Miles per gallon of a vehicle is a random variable with a uniform distribution from 23
to 47. The probability that a random vehicle gets between 28 and 36 miles per gallon
is: Answer: (Round to four decimal places)

Answers

Answer:

Step-by-step explanation:

The range of the uniform distribution is from 23 to 47, so the minimum value (a) is 23 and the maximum value (b) is 47.

The probability density function for a uniform distribution is:

f(x) = 1 / (b - a) if a ≤ x ≤ b

= 0 otherwise

We want to find the probability that a random vehicle gets between 28 and 36 miles per gallon. This is the same as finding the area under the probability density function between x = 28 and x = 36.

Since the distribution is uniform, the probability density function is a horizontal line between x = 23 and x = 47, with height equal to 1 / (47 - 23) = 1/24.

The area under the probability density function between x = 28 and x = 36 is:

P(28 ≤ x ≤ 36) = (36 - 28) * 1/24 = 8/24 = 1/3

Therefore, the probability that a random vehicle gets between 28 and 36 miles per gallon is 1/3, or 0.3333 rounded to four decimal places.

Step-by-step explanation:

Anna is buying a house selling for ​$ 245,000. To obtain the​ mortgage, Anna is required to make a 15​% down payment. Anna obtains a 30​-year mortgage with an interest rate of 5​%.


​a) Determine the amount of the required down payment.
​b) Determine the amount of the mortgage.
​c) Determine the monthly payment for principal and interest.

Answers

Anna's monthly payment for principal and interest is $1,117.78.

How to solve the mortgage problem?

a) The amount of the required down payment can be calculated as follows:

Down payment = 15% of $245,000

Down payment = 0.15 x $245,000

Down payment = $36,750

Therefore, Anna is required to make a down payment of $36,750.

b) The amount of the mortgage can be calculated as follows:

Mortgage = Total price of the house - Down payment

Mortgage = $245,000 - $36,750

Mortgage = $208,250

Therefore, Anna's mortgage amount is $208,250.

c) The monthly payment for principal and interest can be calculated using the formula for a fixed-rate mortgage:

[tex]$M = P\left[\frac{i(1+i)^n}{(1+i)^n-1}\right][/tex]

Where:

M = Monthly Mortgage

P = Principal (amount of the loan)

i = Monthly interest rate (5% / 12 = 0.0041667)

n = Total number of payments (30 years x 12 months = 360)

Plugging in the values, we get:

[tex]$M = \frac{\$208,250 \left[0.0041667(1+0.0041667)^{360}\right]}{\left[(1+0.0041667)^{360}-1\right]}[/tex]

M = $1,117.78

Therefore, Anna's monthly payment for principal and interest is $1,117.78.

4) The value of 5-30+180-1,080+... when n=11 is 302,330,880.

5) Required number of terms are 10 ( approximately)

What is the formula for a finite geometric series?

[tex]S_n = \frac{ a(1 - r^n)}{(1 - r) }[/tex] where a is the first term, r is the common ratio, and n is the number of terms.

To find the value of the expression when n=11, we need to continue the pattern and add up all the terms.

5-30+180-1,080+... can be written as:

5 - 30 + 180 - 1080 + 6480 - 38880 + 233280 - 1,399,680 + 8,398,080 - 50,388,480 + 302,330,880

In this case, a = 5, r = -6, and n = 11. Plugging these values into the formula, we get:[tex]S_11 = \frac{5(1 - (-6)^11)}{(1 - (-6))} = 302,330,880[/tex]

So the answer is A) 302,330,880.

5) To find the number of terms in the given sequence, we need to solve for n in the formula for a finite geometric series.

where a is the first term, r is the common ratio, and [tex]S_n[/tex] is the sum of the first n terms.

In this case, a = 100,000 and r = 1/2, since each term is half the previous one. Also, we know that S_n = 199,609.375 - (6 + 7 + 8 + 9) = 199,588.375. Plugging these values into the formula, we get:

[tex]199,588.375 = 100,000 \times \frac{(1 - (1/2)^n)}{(1 - 1/2)} \\ 199,588.375 = 200,000 \times (1 - (1/2)^n) \\ 0.997942 = (1/2)^n \\ n = \frac{log(0.997942)}{log(1/2)} \\ = 9.9916[/tex]

Kofo saved N30.00 with the post office savings bank for 2 years. At the end of this period he received N2.40 as simple interest on his money. At what rate per annum was the interest paid?

Answers

Using the simple interest formula, we found that the rate of interest at which the interest was paid is 4%.

What is meant by simple interest?

The financial fee for borrowing money is called interest, and it is typically stated as a percentage, such as an annual percentage rate (APR). For the use of their money, lenders may earn interest, and borrowers may pay interest.

A way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time is by using simple interest. Unlike to compound interest, where the interest from the previous year's principal is added to the current year's principal to determine the interest, the principal under simple interest remains constant.

Given,

The principal amount P = 30 naira

The time period t = 2 years

Interest amount received I = 2.40 naira

We are asked to find the rate of the interest r.

the simple interest formula is:

I = ( P *r * t )/ 100

2.4 = (30*r*2)/100

240 = 60r

r = 240/60  = 4%

Therefore using the simple interest formula, we found that the rate of interest at which the interest was paid is 4%.

SECTION III - Show all your working 37. Mr. Morrie shared $1050 among his three children Daniel, Eva and Francis. Eva received $185.00 more than Daniel who received $175.00 less than Francis. How much money did each child receive? ​

Answers

Answer:

Daniel received $230.00, Eva received $415.00, and Francis received $405.00.

Step-by-step explanation:

Let's assume that Daniel received x dollars.

Then, according to the problem, Eva received $185.00 more than Daniel, which means she received (x + 185) dollars.

Similarly, we know that Daniel received $175.00 less than Francis, which means Francis received (x + 175) dollars.

We also know that the total amount of money shared among the three children is $1050.00. Therefore, we can write the following equation:

x + (x + 185) + (x + 175) = 1050

Simplifying the equation:

3x + 360 = 1050

3x = 690

x = 230

Therefore, Daniel received $230.00, Eva received (x + 185) = $415.00, and Francis received (x + 175) = $405.00.

To check that these values are correct, we can verify that they add up to the total amount of money shared:

$230.00 + $415.00 + $405.00 = $1050.00

Therefore, Daniel received $230.00, Eva received $415.00, and Francis received $405.00.

Solve for w.
(w+5)² =2w² +3w+37

Answers

Answer:

w = 3; w = 4

Step-by-step explanation:

We can start by expanding the equation on the left hand side:

[tex](w+5)^2=2w^2+3w+37\\(w+5)(w+5)=2w^2+3w+37\\w^2+5w+5w+25=2w^2+3w+37\\w^2+10w+25=2w^2+3w+37[/tex]

We can first simplify the equation subtracting all the terms on the right hand side and having the equation equal 0:

[tex]w^2+10w+25=2w^2+3w+37\\(w^2-2w^2)+(10w-3w)+(25-37)=0\\-w^2+7w-12=0[/tex]

Now, we have one equation in standard form (ax^2 + bx + c = 0).

We can solve this equation using the quadratic equation which is

[tex]x = \frac{-b+\sqrt{b^2-4ac} }{2a} \\\\x=\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

Since -1 is our a value, 7 is our b, and -12 is c, we simply plug in our values and solve for x:

First x:

[tex]x=\frac{-7+\sqrt{7^2-4(-1)(-12)} }{2(-1)}\\ \\x=\frac{-7+\sqrt{1} }{-2}\\ \\x=\frac{-7+1}{-2}\\ \\x=\frac{-6}{-2}\\ \\x=3[/tex]

Second x:

[tex]x=\frac{-7-\sqrt{7^2-4(-1)(-12)} }{2(-1)}\\ \\x=\frac{-7-\sqrt{1} }{-2}\\ \\x=\frac{-7-1}{-2}\\ \\x=\frac{-8}{-2}\\ \\x=4[/tex]

Finally, we must check for extraneous solutions, which (if present) will make the equations not true.  We simply plug in 3 for w and 4 for w to check for such solutions:

Checking 3:

[tex](3+5)^2=2(3)^2+3(3)+37\\8^2=2(9)+9+37\\64=18+9+37\\64=64[/tex]

Checking 4:

[tex](4+5)^2=2(4)^2+3(4)+37\\9^2=2(16)+12+37\\81=32+12+37\\81=81[/tex]

Since the equations are true for both 3 and 4, both values work for w.

d. Since the standard normal distribution is symmetric, P(-Z₁≤z≤z) = 0.8994 is equivalent to P(0≤z≤Z₁) = 0.4497. Using a standard normal table or calculator, we find that z = 2.66 satisfies this probability.

e. Since the standard normal distribution is symmetric, P(-Zo≤z≤0) = 0.5 - P(0≤z≤Zo) = 0.5 - 0.3106 = 0.1894. Using a standard normal table or calculator, we find that z = -0.84 satisfies this probability.

f. Since the standard normal distribution is symmetric, P(-3≤z≤3) = 0.998. Therefore, P(z>3 or z<-3) = 0.002.

g. P(Z<z) = 0.0014 is equivalent to P(z>-z₁) = 0.0014, where z₁ is the z-value such that P(z≤z₁) = 0.0014. Using a standard normal table or calculator, we find that z₁ = -2.96. Therefore, z > 2.96 satisfies P(Z<z) = 0.0014.

Solve the equation without using a calculator

[tex](x^3-1000)^{1/2}=(x^2+100)^{1/3}[/tex]

Answers

Without using a calculator, the only solution to the equation    [tex](x^3 - 1000)^{1/2} = (x^2 + 100)^{1/3}[/tex] is 10.1136.

What is the solution of the equation?

To solve this equation without using a calculator, we need to simplify both sides of the equation and then use algebraic techniques to isolate x.

[tex](x^3 - 1000)^{1/2} = (x^2 + 100)^{1/3}[/tex]

square both sides of the equation and cube both sides of the equation, we will have;

(x³ - 1000)³ = (x² + 100)²

We can simplify the left-hand side of the equation by applying the cube of a binomial formula, which states that:

(a + b)³ = a³ + 3a²b + 3ab² + b³

Let's apply this formula with a = x³ and b = -1000:

(x³ - 1000)³ = x⁹ - 3x⁶(1000) + 3x³(1000)² - 1000³

Next, let's simplify the right-hand side of the equation:

(x² + 100)² = x⁴ + 200x² + 10000

Now we can substitute these expressions back into the original equation:

x⁹ - 3x⁶(1000) + 3x³(1000)² - 1000³ = x⁴ + 200x² + 10000

We can then rearrange the terms to get a polynomial equation in x:

x⁹ - 3x⁶(1000) + 3x³(1000)² - x⁴ - 200x² - 10000 - 1000³ = 0

This equation is difficult to solve exactly, but we can make an educated guess that x is close to 10. If we substitute x = 10, we get:

(10³ - 1000)³ ≠ (10² + 100)²

Increase the value of x a little, say 10.1136

(10.1136³ - 1000)³ ≈ (10.1136² + 100)²

This is true, so x = 10.1136 is a solution to the equation. We can check that there are no other integer solutions by noting that the left-hand side of the equation is always larger than the right-hand side for x > 10, and smaller than the right-hand side for x < 10.

Therefore, the only solution to the equation is x = 10.1136.

Elena wonders how much water it would take to fill her cup. She drops her pencil in her cup and notices that it just fits diagonally. (See the diagram.) The pencil is 13 cm long and the cup is 12 cm tall. How much water can the cup hold? Explain or show your reasoning.

Answers

Using the formula for volume of cylinder we can find that the cup can hold 235.5cm³ volume of water.

Define volume?

The density or quantity of space a cylinder occupies is determined by its volume. Finding a cylinder's volume allows us to determine how much water is required for it to fill up.

Volume of a cylinder equals circle's area times height.

Volume equals πr² h

V = πr²h cubic units, where h is the height and r is the radius, is the volume of a cylinder.

Let's assume the cup is a cylinder. The pencil length is simulating a diagonal (hypothenuse), which forms a right triangle with the height of the cylinder and the diameter at the bottom. So, we apply Pythagorean's Theorem.

13² = 12² + d²

⇒ d² = 169-144

⇒ d = √25

⇒ d =5cm.

Radius = d/2

= 5/2

=2.5cm.

Now,

Volume of the cup = π × r² × h

= 3.14 × 2.5² × 12

= 235.5cm³.

Therefore, the cup can hold 235.5cm³ volume of water.

what is symmetry?

A balanced and proportionate likeness between an object's two halves is referred to as symmetry in geometry. It implies that one half is the other's mirror image. The term "line of symmetry" refers to the fictitious axis or line that can be used to fold a figure into symmetrical halves.

A symmetrical object is one that is equal on both sides. Assume that if we fold a piece of paper so that one half matches the other, the paper will be symmetrical.

from the question:

The fact that the axis of symmetry goes through the vertex of a parabola can be used to determine the axis of symmetry and vertex of the function [tex]f(2) = 0.5(2)^2 - 2(2) - 2[/tex]

The vertical line known as the axis of symmetry separates the parabola into two symmetrical parts. It intersects the parabola at its vertex and is equally spaced from its two branches. The following is the equation for the axis of symmetry:

x = -b/2a

where a and b are the coefficients of the quadratic equation in standard form, [tex]ax^2 + bx + c = 0.[/tex]

In this case, a = 0.5 and b = -2, so the equation of the axis of symmetry is:

x = -(-2)/(2*0.5) = 2

Hence, a vertical line going through x = 2 serves as the axis of symmetry.

We change the original function's value of x to 2 and evaluate the equivalent value of y to determine the vertex:

[tex]f(2) = 0.5(2)^2 - 2(2) - 2[/tex]

Antonina goes on Wheel of Fortune and wins $12,000 after taxes. She decides that she will invest this money with the goal of putting a $20,400 down payment on a house. She puts the money in a mutual fund that has had a historical return of 7.5%.
a. (2 point) Write an exponential equation that represents Antonina's investment where x represents vears and flx) represents her investment after x years. Assume the mutual fund earns a 7.5 annual rate of return.
b. (2 point) Calculate how long it will take to reach her investment goal. Round to 2 decimal places.

What is mutual fund?

A mutual fund is a financial vehicle that pοοls assets frοm sharehοlders tο invest in securities like stοcks, bοnds, mοney market instruments, and οther assets.

a. The expοnential equatiοn that represents Antοnina's investment is:

[tex]f(x) = 12000(1 + 0.075)^x[/tex]

Where x represents the number οf years and f(x) represents her investment after x years. The initial investment is $12,000, and the annual rate οf return is 7.5%, which is added tο the principal amοunt each year.

b. We want tο sοlve fοr x in the equatiοn:

[tex]12000(1 + 0.075)^x = 20400[/tex]

Dividing bοth sides by 12,000, we get:

[tex](1 + 0.075)^x = 17/10[/tex]

Taking the natural lοgarithm οf bοth sides, we get:

[tex]ln(1 + 0.075)^x = ln(17/10)[/tex]

Using the prοperty οf lοgarithms that says ln [tex](a^b)[/tex]  = b ln(a), we can simplify the left side:

x ln(1 + 0.075) = ln(17/10)

Dividing bοth sides by ln(1 + 0.075), we get:

x = ln(17/10) / ln(1 + 0.075)

Using a calculatοr, we find that x ≈ 8.86 years. Therefοre, it will take Antοnina abοut 8.86 years tο reach her investment gοal οf $20,400.

section of her yard. In her sketch, what is the area of the shaded region?
Factor out the GCF. Explain.

Answers

The area of the shaded region equals 21.43 sq. units.

Why do we use area?

When calculating how much material is needed to cover a wooden table, how many tiles are needed to tile the floor, how much space is needed for a parking lot, how much paint is needed for the walls, etc., we employ the notion of area.

Given, A circle is circumscribed in the square,

Area of shaded region = area of square - area of circle

Area of square = Side²

= 10 × 10 = 100 sq. units,

Area of circle = Πr²

Radius = Diameter / 2

radius = 10 / 2 = 5 units

Area of circle = 22/7 × 5 × 5

= 78.57 sq. units

Area of shaded region = 100 - 78.57,

10. What is BD? Show work to support your answer.

Answers

Answer:

BD = 8

Step-by-step explanation:

To solve this, you need to use Pythagorean theorem which states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

For △ABC, AC (4+16) is the hypotenuse

=> AC^2 = AB^2 + BC^2

For △ABD, AB is the hypotenuse

=> AB^2 = AD^2 + BD^2

For △BCD, BC is the hypotenuse

=> BC^2 = BD^2 + CD^2

Therefore

AC^2 = AB^2 + BC^2

AC^2 = (AD^2 + BD^2) + (BD^2 + CD^2)

20^2 = 4^2 + BD^2 + BD^2 + 16^2

400 - 16 - 256 = 2BD^2

BD^2 = 128/2 = 64

BD = √64 = 8

order the angles from least to greatest 21m 24m 17m

Answers

The order of the angles is 43.8°, 63.2, and 75.02 (Here the values are approximate values).

Ordering the angles of the triangle:

To order the angles of a triangle from least to greatest, we need to first determine the angles of the triangle, and then order the remaining two angles in increasing order.

The formulas we used are

Cosine formula:  Cos C = (a² + b² - c²)/2ab

Law of sine:     a/ sin(A) = b / sin(B) = c / sin(C)

Here we have

The sides of the triangle are 21m 24m and 17m  

Use the Law of Cosines to find one of the angles

=> Cos C = (a² + b² - c²)/2ab

Where a, b, and c are the lengths of the sides of the triangle, and C is the angle opposite the side of length c.

In this case, we have:

a = 21 m, b = 24 m and c = 17 m

Cos(C) = (21² + 24² - 17²) / (2 × 21 × 24)

Cos (C) = 728/1008 = 0.722  

C = cos⁻¹(0.722) = 43.8°

So angle C is 43.8°, which is the smallest angle in the triangle.

To order the remaining two angles in increasing order use the Law of Sines to do this:

a / sin(A) = b / sin(B) = c / sin(C)

=> 21/sin(A) = 24 / sin(B) = 17 / sin(43.78)

=> 21/sin(A) = 24 / sin(B) = 17 /0.69

=> 21/sin(A) = 17/0.69  

=> Sin A = (21 × 0.69)/17

=> Sin A = 0.85

=> A = Sin⁻¹(0.85)

=> A = 63.2

=> 24 / sin(B) = 17 /0.69

=> Sin B = (24 × 0.69)/17

=> Sin B = 0.97

=> B = Sin⁻¹(0.97)

=> B = 75.02

Hence, the order of the angles is 43.8°, 63.2, and 75.02

Therefore,

The order of the angles is 43.8°, 63.2, and 75.02 (Here the values are approximate values).
