Experiment 1: Select ONE card from a deck of cards Create two events A and B. For example: Let A = observing a card with an odd number on it B = observing a king Mix and match two events anyway you like.

Answer:

75.36

Step-by-step explanation:

Area of the top of the snowman

A=πr^2

A=3.14(5)^2

A=78.5

A=πr^2

A=3.14(7)^2

A=153.86

The difference of the areas:

153.86-78.5

=75.36

Answer: -(m/n) = (m/n)^-1 = 1 / (m/n)

Hence, a^-(m/n) = (1 / a^(m/n)) where m,n are rational numbers.

For example: let 1/2 be rational number and 4 be real number then, 4^-(1/2) = 0.5 = 1/(4^(1/2))

You're using Newton's method to find the roots to

f(x) = g(x)   →   x ⁶ = cos(x)

Recast this as finding the roots to

h(x) = f(x) - g(x) = x ⁶ - cos(x)

First, get the tangent line approximation L(x) to h(x) at an arbitrary starting point x = x₀ ; in a small neighborhood of x₀, we have

h(x) ≈ L(x) = h(x₀) + h'(x₀) (x - x₀)

Find the root to the tangent line function:

0 = h(x₀) + h'(x₀) (x - x₀)   →   x = x₁ = x₀ - h(x₀)/h'(x₀)

x₁ is the first approximation of a root to h(x). Repeat the process - that is, take the tangent line to h(x) at x₁ to find the next approximation x₂, and so on - until you meet the required condition.

For the smaller root, take x₀ = -π/2 :

x₀ ≈ -1.5708

x₁ = x₀ - h(x₀)/h'(x₀) ≈ -1.31348

x₂ = x₁ - h(x₁)/h'(x₁) ≈ -1.11366

x₃ = x₂ - h(x₂)/h'(x₂) ≈ -0.982446

x₄ = x₃ - h(x₃)/h'(x₃) ≈ -0.928013

x₅ = x₄ - h(x₄)/h'(x₄) ≈ -0.920039

x₆ = x₅ - h(x₅)/h'(x₅) ≈ -0.919887

Stop at x₆ because |x₆ - x₅| ≤ 0.001.

For the larger root, you can start the process over with a different seed for x₀, such as π/2. But since h(x) is an even function and symmetric about the y-axis, the larger root will just be the same root with positive sign, 0.919887.

Answer:

45 mushrooms

Step-by-step explanation:

Ella and Ola had 70 mushrooms altogether. 5/9 of Ella's mushrooms are brown and 2/17 of Ola's mushrooms are white. How many mushrooms did Ella have?

Let the amount of Ella's mushrooms be x

Let the amount of Ola's mushrooms be y

If Ella and Ola had 70 mushrooms altogether, then;

x + y = 70

5/9 x = brown

2/17 y = white

Substiute

x + 5/9 x = 70

14 x/9 = 70

14x = 9 * 70

x = 9* 5

x = 45

Hence Ella has 45 mushrooms

Answer:

[tex]\bf\Huge 65 [/tex]

Step-by-step explanation:

finding the original price

⟼ 100 •/• - 10 •/• = 90•/•

⟼ 90.•/• = $ 58•50

⟼ 1 •/• = $ 58•50 / 90

⟼ 100 •/• = $ 58•50 / 90 × 100

⟼ 100 •/• = $ 5850 / 90

⟼ 100 •/• = $ 585 / 9

⟼ 100 •/• = $ 65.

∴ the original price is $ 65.

Step-by-step explanation:

1. simple interest

I= p × r × t

I = 1050 × 4.5 × 2

I = $9450

2. principal

p = I/(rt)

p= 22.50/ (3× 3)

p = 22.50/9

p = $2.5

3. simple interest

I= p × r × t

I = 500 × 5 × 3

I = $7500

4. time

first convert r to decimal

r= r/100, r= 3.5 / 100

r= 0.035

t = i/(pr)

t = 43.75/ (2500× 0.035)

t = 43.75/ 87.5

t = 0.5 year or 6 months

Answer:

Remember that the Pythagorean's theorem says that:

For a triangle rectangle with hypotenuse H and catheti A and B:

H^2 = A^2 + B^2

Here we also need to remember that the area of a square of side length L is:

area = L^2

Now let's solve this.

First, we start with two squares, one of side length a and the other of side length b.

Such that the complete area in the first image is:

area = a^2 + b^2

Now we draw two triangle rectangles with catheti a and b, and with hypotenuse c.

in step 3, we rotate those triangles in order to make a larger square, with side length c, with an area equal to:

area = c^2

Notice that we never added more shapes, so the area of the image did not change in all this process, then the initial area must be equal to the final area:

a^2 + b^2 = area = c^2

a^2 + b^2 = c^2

And remember that a and b are the catheti of the triangles, and c is the hypotenuse, then this is the Pythagorean's theorem.

Answer:

Speed of first plane is  350 miles per hour

Speed of second plane is 100 miles per hour

Step-by-step explanation:

Let the speed of the second plane be X

Then the speed of the first plane will be 3.5 X

Distance travelled by first plane is 9.5 *X

Distance travelled by second plane is 9.5 * 3.5 X

Difference of distance between the two plane is

[tex]9.5 * 3.5 X - 9.5 *X = 2375\\23.75 X = 2375\\X = 100[/tex]miles per hour

Speed of first plane is 3.5 *100 = 350 miles per hour

Speed of second plane is 100 miles per hour

Step-by-step explanation:

The original function is f(m) = 5(1.07)^m, with the m as an exponent

part A) if the final length is 9.19, we can set f(m) = 9.19 and solve for m

plugging it into a calculator, I get m = ~8.99, so a bit less than 9. therefore, a reasonable domain might be all the m values 9 or below, or m ≤ 9

part B) the y-intercept of a function is the value of the independent variable when the dependent variable = 0. the two variables in your problem are height and number of months - which one do you think is the independent one, and which one is dependent? then re-interpret "value of the independent variable when the dependent variable = 0" in terms of the actual quantities that the variables represent

part C) average rate of change from m = 1 to m = 9

f(9)−f(1)9−1

evaluate, and think about what that represents in terms of height and number of months

Step-by-step explanation:  Reflecting across the y axis changes the x coordinates.

i would say the answer is 5/8

because c is 3/4

Answer:

Since the fraction of this is very obviously 24/30, here's how you can get a decimal out of that:

First, you simplify that fraction.

24/30 = 4/5, since 5x6 is 30 and 6x4 is 24

Now, it's pretty easy to convert 4/5 into a decimal.

This is how I like to do it. You re-convert the fraction one step higher, so it's 8/10, and you just turn it into 0.8, since it's all out of 10.

I hope I helped, and I'd appreciate a "Brainliest"! ☺

Answer:

5 cups of flour

Step-by-step explanation:

if mandy wants a total of 10 dozen muffins, and 2.5 dozen of muffins require 1.25 cups, you'd first have to divide 10 by 2.5 to get the answer of 4. this means that per 2.5 dozen muffins she will need 4 times the amount of materials in order to get a total amount of 10 dozen muffins. therefore if 2.5 dozen muffins require 1.25 cups of flour, then you'd need to multiply 1.25 by 4 which is equivalent to 5 cups of flour.

written math;

10/2.5=4

1.25*4=5

answer=5 cups of flour

Answer:

Future value using simple interest = $10,880

Future value using Compound interest = $11,240 (Approx.)

Step-by-step explanation:

Given:

Principal Amount = $8,000

Rate = 12% = 0.12

Number of year = 3

Find:

Future value

Computation:

Future value using simple interest

Future value = P + (P)(R)(T)

Future value = 8,000 + (8,000)(0.12)(3)

Future value = 8,000 + 2,880

Future value using simple interest = $10,880

Future value using Compound interest

Future value = P[1+r]ⁿ

Future value = 8,000[1+0.12]³

Future value = 8,000[1.12]³

Future value using Compound interest = $11,240 (Approx.)

Answer:

The bill is $1837.5

Step-by-step explanation:

Given

[tex]B = Bills[/tex]

[tex]T = Temperature[/tex]

[tex]B\ \alpha\ \frac{1}{T}[/tex] --- The variation

T = 35; when B = 210

Required

Find B when T = 40

[tex]B\ \alpha\ \frac{1}{T}[/tex]

Express as an equation

[tex]B = \frac{k}{T}[/tex]

Make k the subject

[tex]k = BT[/tex]

T = 35; when B = 210

[tex]k = 35 * 210[/tex]

[tex]k = 7350[/tex]

When T = 40, we have:

[tex]k = BT[/tex]

[tex]7350 = B * 40[/tex]

Make B the subject

[tex]B = \frac{7350}{4}[/tex]

[tex]B = 1837.5[/tex]

Answer:

Corson had a better performance at the skills competition.

Step-by-step explanation:

In order to determine which player had a better performance at the skills competition, we need to find the percentage performance of both the players.

Therefore,

Corson's percentage performance

[tex] =\frac{5}{7}\times 100= 71.43%[/tex]

Charleigh's percentage performance

[tex] =\frac{3}{5}\times 100= 60%[/tex]

[tex] \because [/tex] Corson's percentage performance > Charleigh's percentage performance

So, Corson had a better performance at the skills competition.

Answer:

7

Step-by-step explanation:

to find the circumference of a circle the equation is C=πd where C is circumference, d is diameter, and using 3.14 for π

once we plug in the known information we are left with

22=(3.14)d

all that's left is to solve for d

22=(3.14)d

22/3.14=(3.14)/3.14 d

7=1d

7=d
