Answer:
it's 65 because if u count the inside of the boxes u get 65
Answer:
34
Step-by-step explanation:
to get the perimeter you add the side-A with Base-B and Side-C.
The base at the bottom is 10 and the two symmetrical sides is 12.
P= a + b + c
34= 12 + 10 + 12

Test Booklet AP CollegeBoard AP Statistics Name Unit 7, part 2 Test (MC) 1. A statistics student wants to compare the mean times needed to access flight information for two major airlines. Twenty randomly selected students accessed one airline's Web site, and the time required to locate the flight information using the Web site had a mean of 2.5 minutes and a standard deviation of 0.8 minute. Twenty different randomly selected students accessed the other airline's Web site, and the time required to locate the flight information using the Web site had a mean of 2.1 minutes and a standard deviation of 1.1 minutes. Assuming that the conditions for inference are met, which of the following statements about the p- value obtained from the data and the conclusion of the significance test is true?
A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two Web sites
B. The p-value is greater than 0.01 but less than 0.05, therefore, there is a significant difference in mean search times on the two Web sites.
C. The p-value is greater than 0.05 but less than 0.10, therefore, there is a significant difference in mean search times on the two Web sites.
D. The p-value is greater than 0.10, therefore, there is no significant difference in mean search times on the two Web sites
E. Since this is a matched-pairs situation, additional information is needed to perform a test of significance
Answer:
The statement about the p-value obtained from the data and the conclusion of the significant test that is true is option D
D. The p-value is greater than 0.10, therefore, there is no significant difference in mean search times on the two Web sites
Step-by-step explanation:
From the question, the statistics student wants to compare the mean times needed to access flight information for two airlines
Let 'A' represent one of the airlines and let 'B' represent the other airline
In the statistics hypothesis test we have;
The mean time to access airline A's website, [tex]\overline x_1[/tex] = 2.5 minutes
The standard deviation to access airline A's website, s₁ = 0.8 minutes
The mean time to access airline B's website, [tex]\overline x_2[/tex] = 2.1 minutes
The standard deviation to access airline B's website, s₂ = 1.1 minutes
The t-test is given as follows;
The null hypothesis is H₀; μ₂ - μ₁ = 0
The alternative hypothesis is H₀; μ₂ - μ₁ ≠ 0
[tex]t=\dfrac{(\bar{x}_{1}-\bar{x}_{2})}{\sqrt{\dfrac{s_{1}^{2} }{n_{1}}+\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]
The critical-t at n₁ + n₂ - 2 = 20 + 20 - 2 = 38 degrees of freedom is therefore, from a graphing calculator, the critical-t = ±2.734 and the probability = 0.197;
[tex]t=\dfrac{(2.5-2.1)}{\sqrt{\dfrac{0.8^{2} }{20}+\dfrac{1.1^{2}}{20}}} \approx 1.32[/tex]
Therefore, given that the test statistic is smaller than the critical-t, and the p-value is greater than the significance level of 0.01 and is also larger than 0.10, therefore, there is no significant difference in mean search times on the two Web sites.

Please help!! it's due in an hour, If you answer Street F, I will mark you the Brainlyist answer
Answer:
y=-3/4+9
Step-by-step explanation:
First off we know that they are parallel, so they have to have the same slope.
y=-3/4
that is all we have for now, so we have to find b, the y intercept
we know that Street F passes through the point (4,6), so we graph that.
now we look at the graph and we can see that it look like we can translate it up 7 units.
this will give us the equation
y=-3/4+9
this is the answer hope this helps!

Find the volume of a rectangular prism with the dimensions:
length: 4 yd
width: 5 ft
height: 11 ft
(keep in mind, that 1 of them is yards and the rest are feet)
Answer:
220
Step-by-step explanation:
V= whl = 5 · 11 · 4 = 220
Find the volume of a rectangular prism with the dimensions:
length: 4 yd
width: 5 ft
height: 11 ft
Answer:-Given:-[tex] \bullet [/tex] Length of a rectangular prism = 4 yards = 4 × 3 = 12 feet.
[tex] \bullet [/tex] Breadth of a rectangular prism = 5 feet.
[tex] \bullet [/tex] Height of a rectangular prism = 11 feet.
To Find:-The volume of a rectangular prism.
Solution:-We know,
Formula of Volume of a rectangular prism is (Length × Breadth × Height) cubic units.
So, Volume = (12 × 5 × 11) cubic feet
Volume = 660 cubic feet
The volume of a rectangular prism is 660 cubic feet. [Answer]A small business office uses 1,613 pieces of paper every 4 days. Which is a reasonable estimate for the pieces of paper the business office uses in 7 days?

Mr. Juarez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest. What is the total amount that Mr. Juarez will have in his account at the end of 3 years?
Answer:
$576.80
Step-by-step explanation:
We have been given that Mr. Juárez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest.
We are asked to find the total amount that Mr. Juárez will have in his account at the end of 3 years.
We will use simple interest formula to solve our given problem.
[tex]A=P (1+rt)[/tex]
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
t = Time in years.
Let us convert 1% into decimal form,
1%=1/100=0.01
P=$560 and t=3
A=$560 (1+0.01(3))
A=$560 (1+0.03)
A= $560 (1.03)
A= $576.80
Therefore, Mr. Juárez will have $576. 80 in his account at the end of 3 years. Hope this helps!
A local hamburger shop sold a combined total of 375 hamburgers and cheeseburgers on Friday. There were 75 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Friday? hurry please lol
Answer: 225 hamburgers were sold on friday
Step-by-step explanation:
Let x represent number of hamburgers
and x-75 represent cheeseburgers
such that total hamburgers and cheeseburgers sold on Friday equaling 375 can be represented as
x + (x-75) =375
2x-75=375
2x=375+75
2x =450
x=450/2=225
Hamburgers =225
cheeseburgers= x-75=225-75=150

A chef added 3/4 teaspoon of pepper and 1 1/2 teaspoons of salt to each pot of spaghetti sauce. How much pepper and salt combined are needed in order to make 5 pots of spaghetti sauce?
Answer:
11 1/4 teaspoons
Step-by-step explanation:
So 3/4 + 1 1/2 teaspoons are in one pot, which means 5(3/4 + 1 1/2) teaspoons are in 5 pots.
5(3/4 + 1 1/2)
5(2 1/4)
10 5/4
11 1/4
Total pepper and salt combined are needed in order to make 5 pots of spaghetti sauce is, 45 / 4
We have to given that,
A chef added 3/4 teaspoon of pepper and 1 1/2 teaspoons of salt to each pot of spaghetti sauce.
Here, Total amount of pepper and salt for each pot of spaghetti sauce is,
3/4 + 1 1/2
3/4 + 3/2
Make denominator same by taking LCM of 4,2 which is 4.
3/4 + 6/4
(3 + 6) / 4
9/4
Therefore, Total pepper and salt combined are needed in order to make 5 pots of spaghetti sauce is,
5 x 9/4
45 / 4

Step-by-step explanation:
Given:
Angle of section = 35°
Radius of circle = 5 inch
Find:
Area of shaded section
Computation:
Area of shaded section = Area of sector of circle
Area of sector of circle = [θ/360][πr²]
Area of sector of circle = [35/360][(22/7)(5)²]
Area of sector of circle = [0.0972][(3.14)(25)]

How do I do these two? I’m so confused-
Answer:
1: 58
2: 140
Step-by-step explanation:
For blank 1:
arc SU is 180, this is because its the angle of the diameter.
arc TU is 122, because its the double of angle S, so 61 times 2 is 122.
- We know that a circle is 360 degrees, so 180 + 122 is 302
-Therefore 360-302=58.
For question 5:
Arc CA is 180, because it's the angle of the perimeter
Arc BC is 40, because its the double of angle A, so 20 times 2 is 40.
- We know that a circle is 360 degrees, so 180 + 40 is 220.
- Therefore 360-220=140

3/12 x 6 with explanation!
Answer:
24 is the ans...................
Answer:
1 1/2
Step-by-step explanation:
3/12 * 6
6 is simply 6/1 so
3/12*6/1
multiply from side to side so
3*6=18
and
12*1=12
18/12
simplify to a mixed number
18 goes in 12 once with a remainder of 6, or 18-12=6 so
1 6/12
6/12 can both be simplified by 6 so you divide both by 6
6/6=1 and 12/6=2
1/2
add it back to the whole number
