Answer:
A
Step-by-step explanation:
If the dice are fair and 6 sided then you can roll a 4 in three ways
2 2
1 3
3 1
The total number of ways you can throw two 6 sided dice is 6 * 6 or 36
So P(4) = 3/36 = 1/12

Answer:
8.8
Step-by-step explanation:
To find the hypotenuse...
a²+b²=c²
C is the hypotenuse, so we add the others...
8.4²+2.6²=c²
70.56+6.76=c
77.32=c
Now, square root c to bring it to its original position.
√77.32=8.8
Your answer is 8.8 yards.

Solid fats are more likely to raise blood cholesterol levels than liquid fats. Suppose a nutritionist analyzed the percentage of saturated fat for a sample of 6 brands of stick margarine (solid fat) and for a sample of 6 brands of liquid margarine and obtained the following results: Exam Image Exam Image We want to determine if there a significant difference in the average amount of saturated fat in solid and liquid fats. What is the test statistic
Answer:
[tex]t = 31.29[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{ccccccc}{Stick} & {25.8} & {26.9} & {26.2} & {25.3} & {26.7}& {26.1} \ \\ {Liquid} & {16.9} & {17.4} & {16.8} & {16.2} & {17.3}& {16.8} \ \end{array}[/tex]
Required
Determine the test statistic
Let the dataset of stick be A and Liquid be B.
We start by calculating the mean of each dataset;
[tex]\bar x =\frac{\sum x}{n}[/tex]
n, in both datasets in 6
For A
[tex]\bar x_A =\frac{25.8+26.9+26.2+25.3+26.7+26.1}{6}[/tex]
[tex]\bar x_A =\frac{157}{6}[/tex]
[tex]\bar x_A =26.17[/tex]
For B
[tex]\bar x_B =\frac{16.9+17.4+16.8+16.2+17.3+16.8}{6}[/tex]
[tex]\bar x_B =\frac{101.4}{6}[/tex]
[tex]\bar x_B =16.9[/tex]
Next, calculate the sample standard deviation
This is calculated using:
[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
For A
[tex]s_A = \sqrt{\frac{\sum(x - \bar x_A)^2}{n-1}}[/tex]
[tex]s_A = \sqrt{\frac{(25.8-26.17)^2+(26.9-26.17)^2+(26.2-26.17)^2+(25.3-26.17)^2+(26.7-26.17)^2+(26.1-26.17)^2}{6-1}}[/tex]
[tex]s_A = \sqrt{\frac{1.7134}{5}}[/tex]
[tex]s_A = \sqrt{0.34268}[/tex]
[tex]s_A = 0.5854[/tex]
For B
[tex]s_B = \sqrt{\frac{\sum(x - \bar x_B)^2}{n-1}}[/tex]
[tex]s_B = \sqrt{\frac{(16.9 - 16.9)^2+(17.4- 16.9)^2+(16.8- 16.9)^2+(16.2- 16.9)^2+(17.3- 16.9)^2+(16.8- 16.9)^2}{6-1}}[/tex]
[tex]s_B = \sqrt{\frac{0.92}{5}}[/tex]
[tex]s_B = \sqrt{0.184}[/tex]
[tex]s_B = 0.4290[/tex]
Calculate the pooled variance
[tex]S_p^2 = \frac{(n_A - 1)*s_A^2 + (n_B - 1)*s_B^2}{(n_A+n_B-2)}[/tex]
[tex]S_p^2 = \frac{(6 - 1)*0.5854^2 + (6 - 1)*0.4290^2}{(6+6-2)}[/tex]
[tex]S_p^2 = \frac{2.6336708}{10}[/tex]
[tex]S_p^2 = 0.2634[/tex]
Lastly, calculate the test statistic using:
[tex]t = \frac{(\bar x_A - \bar x_B) - (\mu_A - \mu_B)}{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]
We set
[tex]\mu_A = \mu_B[/tex]
So, we have:
[tex]t = \frac{(\bar x_A - \bar x_B) - (\mu_A - \mu_A)}{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]
[tex]t = \frac{(\bar x_A - \bar x_B) }{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]
The equation becomes
[tex]t = \frac{(26.17 - 16.9) }{\sqrt{0.2634/6 +0.2634/6}}[/tex]
[tex]t = \frac{9.27}{\sqrt{0.0878}}[/tex]
[tex]t = \frac{9.27}{0.2963}[/tex]
[tex]t = 31.29[/tex]
The test statistic is 31.29
Find the volume of a pyramid with a square base, where the perimeter of the base is 10.4 in and the height of the pyramid is 9.6 in. Round your answer to the nearest tenth of a cubic inch.
9514 1404 393
Answer:
21.6 in³
Step-by-step explanation:
The volume of a square pyramid is given in terms of perimeter and height by ...
V = (1/48)P²h
V = (1/48)(10.4 in)²(9.6 in) ≈ 21.6 in³
The volume is about 21.6 cubic inches.
Select all the polygons that would be used in a net of the solid figure shown.
A triangular pyramid. The base has all three sides equal in length. The pyramid is taller than the width of the base.

Answer:
C, definitely two sides are different in the triangle.
A, it looks as if the bottom is a right triangle if you look at it in a different way.
The polygons that would be used in a net isosceles triangle & right triangle
What is Pyramid?A pyramid is a structure whose outer surfaces are triangular and converge to a single step at the top,
As, we need a triangular pyramid whose base has all the three sides equal in length.
We can have a net in the form of isosceles triangle whose two are equal
i.e., two sides are different in the triangle.
and also, bottom with the right angle
i.e., the bottom is a right triangle if you look at it in a different way.

The circle graph shows the percent of time different people took turns driving during a 20-hour road trip.
How many hours did Dan drive?
==========================================================
Explanation:
Add up the percentage values:
25+20+6+6+6 = 63
This means 63% of the trip was driven by anyone but Dan. That must mean 100-63 = 37% of the trip is how much Dan drove.
Apply this percentage to the 20 hour duration
37% of 20 = 0.37*20 = 7.4 hours represents how long Dan drove.
extra notes:
7.4 hours = 7 hours, 24 minutes because 0.4 hours = 0.4*60 = 24 minutes7.4 hours = 7 hrs + 24 min = 7*60+24 = 444 minutesPlease help me!

Answer:
94
Step-by-step explanation:
So
376= x + 3x
Where x is the hambugers and 3 x is cheeseburgers
so it is the same as
376= 4x
divide both sides by 4
x= 94
we can check by tripling x = 283 and adding the hamburgers we found to be 94 which gives us 376

A reporter for a student newspaper is writing an article on the cost of off-campus housing. A sample was selected of 10 one-bedroom units within a half-mile of campus and the rents paid. The sample mean is $550 and the sample standard deviation is $60.05. Provide a 95% confidence interval estimate of the mean rent per month for the population of one-bedroom units within a half-mile of campus. Assume that population is normally distributed.
Answer:
(507.05, 592.95)
Step-by-step explanation:
Given data:
sample mean = $550, sample standard deviation S = $60.05
95% confidence interval , n = 10
For 95% confidence interval for the mean
mean ± M.E.
where M.E. is margin of error = [tex]t_{n-1}, \alpha/2\times\frac{S}{\sqrt{n} }[/tex]
Substituting the values in above equation
[tex]=t_{10-1}, 0.05/2\times\frac{60.05}{\sqrt{10} }[/tex]
= 2.62×18.99
=42.955
= 550±42.95
=(507.05, 592.95)
