Answer:
[tex]2x + 3y[/tex]
Step-by-step explanation:
Given
Shape: Triangle
[tex]P = 5x + 2y[/tex]
Sides: [tex]2x - 3y[/tex] and [tex]x + 2y[/tex]
Required
The measure of the third side
The perimeter of a triangle is the sum of all three sides;
Let the third side be represented by Side3
Hence;
[tex]Side3 + 2x - 3y + x + 2y = 5x + 2y[/tex]
Collect like terms
[tex]Side3 + 2x + x - 3y + 2y = 5x + 2y[/tex]
[tex]Side3 + 3x - y = 5x + 2y[/tex]
Collect like terms
[tex]Side3 = 5x + 2y - 3x + y[/tex]
[tex]Side3 = 5x - 3x + 2y + y[/tex]
[tex]Side3 = 2x + 3y[/tex]
Hence, the measure of the third side is 2x + 3y

-8h = -40
h = -40/-8
h = 5
A local doctor’s office logged the number of patients seen in one day by the doctor for ten days. Find the means, median, range, and midrange of the patients seem in 10 days. 27 31 27 35 35 25 28 35 33 24
Answer:
Mean = 30, Median = 29.5, Range = 9 and Mid-range = 29.5.
Step-by-step explanation:
We are given that a local doctor’s office logged the number of patients seen in one day by the doctor for ten days.
Arranging the given data in ascending order we get;
24, 25, 27, 27, 28, 31, 33, 35, 35, 35.
(a) Mean is calculated by using the following formula;
Mean, [tex]\bar X[/tex] = [tex]\frac{\text{Sum of all values}}{\text{Total number of observations}}[/tex]
= [tex]\frac{27+ 31+ 27+ 35+ 35+ 25+ 28+ 35+ 33+ 24}{10}[/tex]
= [tex]\frac{300}{10}[/tex] = 30
So, the mean of the given data is 30.
(b) For calculating the median, we have to first have to observe that the number of observations (n) in the data is even or odd.
If n is odd, then the formula for calculating median is given by;Median = [tex](\frac{n+1}{2})^{th} \text{ obs.}[/tex]
If n is even, then the formula for calculating median is given by;Median = [tex]\frac{(\frac{n}{2})^{th} \text{ obs.}+ (\frac{n}{2}+1)^{th} \text{ obs.} }{2}[/tex]
Here, the number of observations is even, i.e. n = 10.
So, Median = [tex]\frac{(\frac{n}{2})^{th} \text{ obs.}+ (\frac{n}{2}+1)^{th} \text{ obs.} }{2}[/tex]
= [tex]\frac{(\frac{10}{2})^{th} \text{ obs.}+ (\frac{10}{2}+1)^{th} \text{ obs.} }{2}[/tex]
= [tex]\frac{(5)^{th} \text{ obs.}+ (6)^{th} \text{ obs.} }{2}[/tex]
= [tex]\frac{28+31}{2}[/tex]
= [tex]\frac{59}{2}[/tex] = 29.5
So, the median of the data is 29.5.
(c) The range of the data is given by = Highest value - Lowest value
= 35 - 24 = 9
So, the range of the data is 9.
(d) Mid-range of the data is given by the following formula;
Mid-range = [tex]\frac{\text{Highest value}+\text{Lowest value}}{2}[/tex]
= [tex]\frac{35+24}{2}[/tex] = 29.5
An equilateral triangular plate with sides 8 m is submerged vertically in water so that the base is even with the surface. Express the hydrostatic force against one side of the plate as an integral and evaluate it.
Answer:
Hydro static force is =18377 N
Step-by-step explanation:
The hydro static force is equals to the hydro static pressure times the area.
The hydro static pressure of a fluid increases as the depth of the fluid increases and the formula of it is given below.
Hydro static Pressure, P = d·g·ρ
Where, d is the depth of the object
g is the gravitational constant
ρ is the density of the fluid
Density of water ρ = [tex]1000 kg/m3[/tex]
=1000 kg/m^3 * 9.8m/s^2 which is √(3/2).a below the water level.
Side of the plate x = 10 m
The hydrostatic force = the pressure at the center x the area =[tex][sqrt(3)/2 m][1000 kg/m^3 * 9.8m/s^2][/tex][tex][(1/2)(3)(8)(sqrt(3)/2) m^2][/tex]=18377 N

b. When H0 cannot be rejected, can we conclude that the manager's claim is wrong?
Yes
No
c. When H0 can be rejected, can we conclude that the manager's claim is wrong?
Yes
No
Answer:
(a) Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \leq[/tex] $600
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > $600
(b) When H0 cannot be rejected, we conclude that the manager's claim is correct.
(c) When H0 can be rejected, we conclude that the manager's claim is wrong.
Step-by-step explanation:
We are given that the manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekend is $600 or less.
The accountant will use a sample of weekend guest bills to test the manager's claim.
Let [tex]\mu[/tex] = population mean guest bill for a weekend
(a) Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \leq[/tex] $600
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > $600
Here null hypothesis states that the mean guest bill for a weekend is $600 or less.
On the other hand, alternate hypothesis states that the mean guest bill for a weekend is more than $600.
(b) When the null hypothesis ([tex]H_0[/tex]) cannot be rejected, then the correct conclusion would be: We conclude that the mean guest bill for a weekend is $600 or less which means that the manager's claim is correct.
(c) When the null hypothesis ([tex]H_0[/tex]) can be rejected, then the correct conclusion would be: We conclude that the mean guest bill for a weekend is more than $600 which means that the manager's claim is wrong.
Line segment ON is perpendicular to line segment ML. What is the length of segment NP?
Answer:
2 units.
Step-by-step explanation:
In this question we use the Pythagorean theorem which is shown below:
Given that
The right triangle OMP
The hypotenuse i.e OM is the circle radius =5 units.
The segment MP = 4 units length
Therefore
[tex]OP^2 + MP^2 = OM^2[/tex]
[tex]OP^2 + 4^2 = 5^2[/tex]
[tex]OP^2 + 16 = 25[/tex]
So OP is 3
Now as we can see that ON is also circle radius so it would be 5 units
And,
ON = OP + PN
So,
PN is
= ON - OP
= 5 units - 3 units
= 2 units

The population of the city of Peachwood is currently 12,000 and increases every year at a rate of 5%. The function that describes the model is ƒ(x) = 12000 • 1.05x. Which of the following choices would be the number of people in the city after one year?
Answer: 12600
Step-by-step explanation:
We are given the function that f(x) = 12000 * 1.05x
the x in f(x) is the amount of years that passed in the city of Peachwood, and the f(x) is the total population of Peachwood
These are two key elements in this function,
Therefore after 1 year the equation would be f(1) = 12000*1.05(1)
or f(1) = 12600

A hiker starting at point P on a straight road wants to reach a forest cabin that is 2 km from a point Q, 3 km down the road from P . She can walk 8 km/hr along the road but only 3 km/hr through the forest. She wants to minimize the time required to reach the cabin. How far down the road should she walk before setting off through the forest straight for the cabin?
Answer:
2.19 km
Step-by-step explanation:
If x is the distance she walks down the road before turning, then the total time is:
t = x/8 + √((3 − x)² + 2²) / 3
t = x/8 + √(9 − 6x + x² + 4) / 3
24t = 3x + 8√(13 − 6x + x²)
24t = 3x + 8(13 − 6x + x²)^½
Take derivative of both sides with respect to x.
24 dt/dx = 3 + 4(13 − 6x + x²)^-½ (-6 + 2x)
When t is a minimum, dt/dx = 0.
0 = 3 + 4(13 − 6x + x²)^-½ (-6 + 2x)
-3 = 4(13 − 6x + x²)^-½ (-6 + 2x)
3 / (6 − 2x) = 4(13 − 6x + x²)^-½
3 / (24 − 8x) = (13 − 6x + x²)^-½
(24 − 8x) / 3 = (13 − 6x + x²)^½
(24 − 8x)² / 9 = 13 − 6x + x²
576 − 384x + 64x² = 117 − 54x + 9x²
459 − 330x + 55x² = 0
Solve with quadratic formula.
x = [ 330 ± √((-330)² − 4(55)(459)) ] / 2(55)
x = (330 ± √7920) / 110
x = 2.19 or 3.81
Since 0 < x < 3, x = 2.19.

A farmer is building a fence to enclose a rectangular area consisting of two separate regions. The four walls and one additional vertical segment (to separate the regions) are made up of fencing, as shown below. A rectangular area consisting of two separated regions. If the farmer has 162 feet of fencing, what are the dimensions of the region which enclose the maximal areas?
Answer:
The maximal area will be "1093.5 square feet".
Step-by-step explanation:
Let,
Length = L feet
Breadth = b feet
Given Total fencing = 162 feet
According to the question,
[tex](2\times L)+(3\times b)=162[/tex]
[tex]2L+3B=162[/tex]
[tex]L=\frac{162-3b}{2}[/tex]
[tex]L=81-\frac{3}{2}b[/tex]
As we know,
[tex]Area=Length\times breadth[/tex]
[tex]=(81-\frac{3}{2}b)\times b[/tex]
[tex]=81b-\frac{3}{2}b^2[/tex]
Now, we required to decrease or minimize the are. So for extreme points:
[tex]\frac{dA}{db}=0[/tex]
or,
[tex]\frac{dA}{dB}=\frac{d}{db}(81-\frac{3}{2}b^2 )=0[/tex]
[tex]81-\frac{3}{2}\times 2\times b=0[/tex]
[tex]b=\frac{81}{3}[/tex]
[tex]b=27 \ feet[/tex]
Now on putting the value of b, we get
[tex]l=81-\frac{3}{2}\times 27[/tex]
[tex]=81-40.5[/tex]
[tex]=40.5 \ feet\\[/tex]
So that the dimensions will be:
⇒ 40.5 feet by 27 feet
Therefore when the dimension are above then the area will be:
= [tex]81\times 27-\frac{3}{2}\times 27\times 27[/tex]
= [tex]2187-\frac{3}{2}\times 729[/tex]
= [tex]2187-1093.5[/tex]
= [tex]1093.5 \ square \ feet[/tex]
Suppose you toss a coin 100 times and get 65 heads and 35 tails. Based on these results, what is the probability that the next flip results in a tail?
Answer:
[tex] P(Head) = \frac{65}{100}=0.65[/tex]
[tex] P(Tail) = \frac{35}{100}=0.35[/tex]
And for this case the probability that in the next flip we will get a tail would be:
[tex] P(Tail) = \frac{35}{100}=0.35[/tex]
Step-by-step explanation:
For this case we know that a coin is toss 100 times and we got 65 heads and 35 tails.
We can calculate the empirical probabilities for each outcome and we got:
[tex] P(Head) = \frac{65}{100}=0.65[/tex]
[tex] P(Tail) = \frac{35}{100}=0.35[/tex]
And for this case the probability that in the next flip we will get a tail would be:
[tex] P(Tail) = \frac{35}{100}=0.35[/tex]

Answer:
a. the probability of a type II error is 0.5319
b. the required sample size to satisfy and the type II error probability is 59.4441

Where ;
∝ = 0.01
From the standard normal tables at critical value ∝ = 0.01 ; the level of significance is -2.575 lower limit and 2.575 upper limit
The z statistics for the lower limit is:
[tex]lower \ limit = \dfrac{\bar X - \mu }{\dfrac{\sigma}{\sqrt {n}}}[/tex]
[tex]-2.575= \dfrac{\bar x - 60 }{\dfrac{4}{\sqrt 25}}}[/tex]

[tex]-2.575*0.8= {\bar x - 60 }{}}}[/tex]
[tex]-2.06= {\bar x - 60 }{}}}[/tex]
[tex]\bar x = 60-2.06[/tex]
[tex]\bar x = 57.94[/tex]
The z statistics for the upper limit is:
[tex]lower \ limit = \dfrac{\bar X - \mu }{\dfrac{\sigma}{\sqrt {n}}}[/tex]
[tex]2.575= \dfrac{\bar x - 60 }{\dfrac{4}{\sqrt 25}}}[/tex]
[tex]2.575= \dfrac{\bar x - 60 }{0.8}}}[/tex]
[tex]2.575*0.8= {\bar x - 60 }{}}}[/tex]
[tex]2.06= {\bar x - 60 }{}}}[/tex]
[tex]\bar x = 60-(-2.06)[/tex]
[tex]\bar x = 60+2.06[/tex]
[tex]\bar x = 62.06[/tex]
Thus; the probability of a type II error is determined as follows:
β = P ( [tex]57.94 < \bar x < 62.06[/tex] )
[tex]= P ( \dfrac{57.94 -62 }{\dfrac{4}{\sqrt{25}}}<\dfrac{62.06 -62 }{\dfrac{4}{\sqrt{25}}})[/tex]
[tex]= P ( \dfrac{-4.06 }{0.8}}<\dfrac{2.06 }{0.8})[/tex]
= P ( -5.08 < Z < 0.08 )
= P ( Z < 0.08) - P ( Z < - 5.08)
Using Excel Function: [ (=NORMDIST (0.08)) - (=NORMDIST(-5.08)) ] ; we have:
= 0.531881372 - 0.00000001887
= 0.531881183
≅ 0.5319
b.
What is the required sample size to satisfy and the type II error probability of b(62) = 0.1
Recall that:
The critical value of ∝ = 2.575 ( i. e [tex]Z_{1 - \alpha/2 } = 2.575[/tex] )
Now ;
the critical value of β is :
[tex]Z _{1- \beta} = 1.28[/tex]
The required sample size to satisfy and the type II error probability is therefore determined as :
[tex]n = [\dfrac{(Z_{1 - \alpha/2} + Z_{1 - \beta} ) \sigma }{\delta}]^2[/tex]
[tex]n = [\dfrac{(2.575+1.28 ) 4 }{2}]^2[/tex]
[tex]n = [\dfrac{(3.855 ) 4 }{2}]^2[/tex]
[tex]n = [\dfrac{(15.42 ) }{2}]^2[/tex]
n = 7.71 ²
n= 59.4441
Thus; the required sample size to satisfy and the type II error probability is 59.4441
A)
In order to calculate the Type II Error, we proceed with stating the factors:
Hypothesized Mean is given as = μ[tex]_{0} [/tex] = 60
True Mean is given as = μa = 62
Standard Deviation is given as = σ = 4
Sample Size = n = 25

Acceptance region is
given as: = μ - Z∝ * σx ≤ Π ≤ μ+Z∝⇄ =57.9360 ≤x≤ 62.0640
Type II Error = probability of not rejecting β = P(57.94-μa/σx)) <Z< (62.064-μa)/σx))
= P (-5.08 <Z< 0.08)

Also refer to the attached graph of the equation where you can verify that the equation has two solutions.
Note:
It is a very common mistake to consider only the positive value and not the negative value.
Consider the square root of 25
[tex]\sqrt{25} = \pm 5 \\\\Since \\\\5 \times 5 = 25 \\\\-5 \times -5 = 25 \\\\[/tex]
That is why we have two solutions for the given equation.

Consider the function g(x) = x^12. Describe the range of the function.
Answer:
0 ≤ g(x) < ∞
Step-by-step explanation:
The range is all non-negative numbers.
___
g(x) is an even-degree polynomial with a positive leading coefficient, so it opens upward. There is no added constant, so its minimum value is zero. The function can take on all values zero or greater.
range: [0, ∞)

The kitchen is 15 feet wide and wight 18ft long. How many 12 inch Square tiles will it take to tile the kitchen floor?
Answer:
270 tiles.
Step-by-step explanation:
The kitchen is 15 x 18 feet. If we multiply we find the area is 270 square feet. one square foot is a 12 x 12 inch square, so we can fit one tile per square foot, giving us 270 tiles.
Suggest changing to “On the graph of an exponential function representing growth, what happens to the slope of the graph as x increases?”
Answer:
If we have a growing exponential relation, we can write it as:
f(x) = A*r^x
Where A is the initial amount, r is the rate of growth, in this case, r > 1 (because is a growing exponential relation)
Now, the "slope" of the graph in x, is equal to the derivate of f(x) in that point, and we have:
f'(x) = A*(r^x)*ln(r)
Now, remember that r > 1, then ln(r) > 0.
then, f'(x) is a growing function as x grows, and f'(x) grows exponentially, this means that the slope of the graph also grows exponentially as x grows.
I paid twice as much by not waiting for a sale and not ordering on line. Which ofthe following statements is also true?
(a) I paid 200% more than I could have online and on sale.
(b) I paid 100% of what I could have online and on sale.
(c) I paid 200% of what I could have online and on sale.
(d) I paid 3 times what I could have online and on sale.
Answer:
Option (c).
Step-by-step explanation:
It is given that, I paid twice as much by not waiting for a sale and not ordering online.
Let the cost of items ordering online be x.
So, now i am paying twice of x = 2x
Now, we have find 2x is what percent of x.
[tex]Percent =\dfrac{2x}{x}\times 100=200\%[/tex]
It means, I paid 200% of what I could have online and on sale.
Therefore, the correct option is (c).

Ujalakhan01! Please help me! ASAP ONLY UJALAKHAN01. What's (x-1)(x-1)?
Answer:
x^2-2x+1
Step-by-step explanation:
We can solve this by using FOIL
First, Outside, Inside, Last
Multiply the x with the x to get x^2
Then x times -1 for the outside numbers to get -x
Then -1 times x for the inside numbers to get -x
And finally -1 and -1 for the last numbers to get 1
Add the two -x to get -2x.
Put it all together
x^2-2x+1
Answer:
[tex]x^2-2x+1[/tex]
Step-by-step explanation:
=> (x-1)(x-1)
USING FOIL
=> [tex]x^2-x-x+1[/tex]
=> [tex]x^2-2x+1[/tex]
What is 6 1/2 subtracted by 2 2/3
Answer:
The answer to this equation is 3 5/6
Step-by-step explanation:
in order to solve this problem, we must first turn these fractions into improper fractions. We can do this by multiplying the base number with the denominator and adding the numerator to that number.
6 1/2 = 13/2
2 2/3 = 8/3
Now, set up your equation.
13/2 - 8/3
Change the denominators to the same number so it will be easier to subtract.
39/6 - 16/6
Now subtract.
23/6 = 3 5/6
Answer:
3 5/6
Step-by-step explanation:
6 1/2 - 2 2/3 = 13/2 - 8/3
(39 - 16)/6 = 23/6 = 3 5/6
