2 1/2 times ? = 5/8
Answer:
1/4
Step-by-step explanation:
Well 2 1/2 is the same thing as 5/2
so we do
5/2 * x(unknown number) = 5/8
2 * 5/2 = 5 * 2/8
5x = 5/4
x = 1/4

A group of teachers decided that they would each bring a similar jar of candies to their classrooms so their
students could practice estimation. The students were told that whoever had the closest guess in the class
would win the candy, and so they all guessed how many candies were in their classroom's jar. The
distribution of individual guesses was strongly skewed to the right with a mean of 115 candies and a
standard deviation of 35 candies.
Suppose we took random samples of 6 students and calculated T as the sample mean of their guesses. We
can assume that the students in each sample are independent.
What will be the shape of the sampling distribution of ?

Which statement describes whether the function is continuous at x = –2?
The function is continuous at x = –2 because f(–2) exists.
The function is continuous at x = –2 because Limit as x approaches negative 2 plus f(x) = f(–2).
The function is not continuous at x = –2 because Limit as x approaches negative 2 f(x) ≠ f(–2).
The function is not continuous at x = –2 because Limit as x approaches negative 2 f(x) does not exist.
Answer: D. The function is not continuous at x = –2 because Limit as x approaches negative 2 f(x) does not exist.

Find the measure of each numbered angle or are.
Answer:
<2 = 133degrees
<1 = 135degrees
Step-by-step explanation:
From the diagram, the angle <2 and 47 are supplementary, hence;
<2 + 47 = 180
<2 = 180 - 47
<2 = 133degrees
To get <1;
47 = 1/2(<1 - 41)
47 * 2 = (<1 - 41)
94 = <1 - 41
<1 = 94 + 41
<1 = 135degrees

A new factory in a small town has an annual payroll of $ million. It is expected that of this money will be spent in the town by factory personnel. The people in this town who receive this money are expected to spend of what they receive in the town, and so on. What is the total of all this spending, called the total economic impact of the factory, on the town each year? Use the formula for the sum of an infinite geometric series.

What is the surface area of the
rectangular prism below?
To Find Surface Area:
So Surface area is found according to this equation SA=2lw+2lh+2hw
6and 1/2 times 2 is 13 that would be the 2 sides
then you do 3 times 6 1/2 which is 19 1/2, which is the top and bottom
finally you do 3 times 9 1/5 which is 27 3/5.
Now since 1/2 and 1/5 are not the same, we find the LCM or Least Common Multiple, which is 10 so 1/2 is multiplied by 5 which is 5/10 and 3/5 is multiplied by 2 which makes 6/10.
Adding 5/10 and 6/10 is 11/10 or 1 1/10
13+6+9=28
28+1 1/10 = 29 1/10
and finally because we did surface area it is 29 1/10 CM^2
__________________________________________________________
To Find Volume:
The Equation used to find volume is l*w*h
The Length is 6 1/2
Height is 9 1/5
width is 3
First, lets again convert the fractions
5/10 and 6/10
6 5/10 times 9 6/10 is 62.4
62.4 times 3 is 187.2
The .2 and be put into 2/10 or 1/5 so the FINAL answer is 187 1/5
Another way to check this is
6*9*3=162
1/5*1/2

9514 1404 393
Answer:
-0.75
Step-by-step explanation:
If the difference is common, it is the difference of any pair of adjacent y-values (for sequential x-values).
-4.5 -(-3.75) = -0.75 . . . . . difference between the first two y-values
The common difference is -0.75.
Use the graph of y=f(x) in the figure to estimate:
f(0)≈
f(1)≈
f(b)≈
f(c)≈
f(d)≈
9514 1404 393
Answer:
f(0) ≈ 22f(1) = 10f(b) ≈ -8f(c) = 0f(d) 24Step-by-step explanation:
This takes graph-reading one step further. You get to estimate the y-value without benefit of minor grid lines. You must mentally divide the 10-unit distance between grid lines into equal spaces. Then estimate how many of those spaces lie between the point and the nearest grid line.
You can do this more precisely by drawing a diagonal line across the grid from one major grid intersection to one that is (5, 1) or (5, -1) major grid points away. Where that line crosses the intermediate grid lines, the vertical measure will be some multiple of 1/5 of the vertical difference between grid points. For example, a line from (0,20) to (5,30) will cross at (1,22), (2,24), (3,26), and (4,28). You can use these reference points to identify the y-values at f(0) and f(d).
Here's our eyeball estimate:
f(0) ≈ 22f(1) = 10f(b) ≈ -8f(c) = 0f(d) 24

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis. Verify your results using the integration capabilities of a graphing utility.y = cos 2xy = 0x = 0x = pi/4
Answer:
[tex]V = \frac{\pi^2}{8}[/tex]
[tex]V = 1.23245[/tex]
Step-by-step explanation:
Given
[tex]y = \cos 2x[/tex]
[tex]y = 0; x = 0; x = \frac{\pi}{4}[/tex]
Required
Determine the volume of the solid generated
Using the disk method approach, we have:
[tex]V = \pi \int\limits^a_b {R(x)^2} \, dx[/tex]
Where
[tex]y = R(x) = \cos 2x[/tex]
[tex]a = \frac{\pi}{4}; b =0[/tex]
So:
[tex]V = \pi \int\limits^a_b {R(x)^2} \, dx[/tex]
Where
[tex]y = R(x) = \cos 2x[/tex]
[tex]a = \frac{\pi}{4}; b =0[/tex]
So:
[tex]V = \pi \int\limits^a_b {R(x)^2} \, dx[/tex]
[tex]V = \pi \int\limits^{\frac{\pi}{4}}_0 {(\cos 2x)^2} \, dx[/tex]
[tex]V = \pi \int\limits^{\frac{\pi}{4}}_0 {\cos^2 (2x)} \, dx[/tex]
Apply the following half angle trigonometry identity;
[tex]\cos^2(x) = \frac{1}{2}[1 + \cos(2x)][/tex]
So, we have:
[tex]\cos^2(2x) = \frac{1}{2}[1 + \cos(2*2x)][/tex]
[tex]\cos^2(2x) = \frac{1}{2}[1 + \cos(4x)][/tex]
Open bracket
[tex]\cos^2(2x) = \frac{1}{2} + \frac{1}{2}\cos(4x)[/tex]
So, we have:
[tex]V = \pi \int\limits^{\frac{\pi}{4}}_0 {\cos^2 (2x)} \, dx[/tex]
[tex]V = \pi \int\limits^{\frac{\pi}{4}}_0 {[\frac{1}{2} + \frac{1}{2}\cos(4x)]} \, dx[/tex]
Integrate
[tex]V = \pi [\frac{x}{2} + \frac{1}{8}\sin(4x)]\limits^{\frac{\pi}{4}}_0[/tex]
Expand
[tex]V = \pi ([\frac{\frac{\pi}{4}}{2} + \frac{1}{8}\sin(4*\frac{\pi}{4})] - [\frac{0}{2} + \frac{1}{8}\sin(4*0)])[/tex]
[tex]V = \pi ([\frac{\frac{\pi}{4}}{2} + \frac{1}{8}\sin(4*\frac{\pi}{4})] - [0 + 0])[/tex]
[tex]V = \pi ([\frac{\frac{\pi}{4}}{2} + \frac{1}{8}\sin(4*\frac{\pi}{4})])[/tex]
[tex]V = \pi ([{\frac{\pi}{8} + \frac{1}{8}\sin(\pi)])[/tex]
[tex]\sin \pi = 0[/tex]
So:
[tex]V = \pi ([{\frac{\pi}{8} + \frac{1}{8}*0])[/tex]
[tex]V = \pi *[{\frac{\pi}{8}][/tex]
[tex]V = \frac{\pi^2}{8}[/tex]
or
[tex]V = \frac{3.14^2}{8}[/tex]
[tex]V = 1.23245[/tex]
A random sample of 10 employees of a company was selected to estimate the mean one-way commute time for all employees at the company. The mean and standard deviation of the sample were 38 minutes and 6 minutes, respectively. Assuming all conditions for inference are met.
Required:
What is the margin of error, in minutes, for a 95 percent confidence interval for the population mean one-way commute time?
Answer:
The margin of error is of 4.22 minutes.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.2622
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
We have that [tex]s = 6, n = 10[/tex]. So
[tex]M = T\frac{s}{\sqrt{n}} = 2.2622\frac{6}{\sqrt{10}} = 4.22[/tex]
The margin of error is of 4.22 minutes.
