Amanter on the edge of a mol has the shape a rectangular prism. It is 9 inches high, 2 inches wide, and 14 feet long. How much water can the gutter hold in cubic inches in gallons? Use the fact that
1231 inches
The gather canto cubic inches of water
Answer:
1.1 gallons
Step-by-step explanation:
Given that the shape of the gutter is in the form of a rectangular prism with length 14 feet, width 2 inches and of height 9 inches.
The volume of the gutter = length x width x height
= 14 x 2 x 9
= 252
The volume of the gutter = 252 cubic inches
But with the given fact, we divide the volume determined by 231 inches.
Then,
the required volume in gallons = [tex]\frac{252}{231}[/tex]
= 1.090908
The gutter can hold water of 1.1 gallons.
Please help me, I will give the best answer brainliest. I have a deadline finish of today, and I really want to get my work done... The following figures show the first two steps of a proof of the pythagorean theorem, which of the following statements about this proof is false? Thank you if you can help :)
Answer:
so since there isn't any pics to work with, here we go.
the pytha theorem states that a^2 + b^2 = c^2, you've probably seen/heard this all the time but really know what it means.
It means the the shorter side of the triangle (the ones that aren't the hypotenuse) multiplied by themselves, and then added together equals the hypotenuse also multiplied by itself.
So if i have a triangle with sides lengths of 3 and 4, and I want to calculate the hypotenuse length, the equation would be 3^2 + 4^2 = x^2
we then get 9 + 16 = x^2 –––––> 25 = x^2 ––––> √25 = x
so the hypotenuse equals 5.
hope this helps.

The Miller family must drive 8 hours to reach their destination. They drive 3 2/3 hours before stopping for the first time. Then they drive 2 3/5 hours before stopping again. How many more hours will it take the Miller family to reach their destination? Use paper to show your work. Enter your answer in the box.
Answer:
1 7/10 hours
Step-by-step explanation:
They need to drive a total of 8 hours. After they drive 3 2/3 hours, they have 4 1/3 left. Then, after another 2 3/5 hours, they now have 1 7/10 hours left.
The number of hours will it take the Miller family to reach their destination is 1¹¹/₁₅ hours.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the Miller family must drive 8 hours to reach their destination. They drive 3²/₃ hours before stopping for the first time. Then they drive 2³/₅ hours before stopping again.
The time will be calculated as,
Time = 8 - 3²/₃ - 2³/₅
Time = 8 - 11/ 3 - 13 / 5
Time = 26 / 15
Time = 1¹¹/₁₅ hours

Answer: Option 'D' is correct.
Explanation:
We are required to find that length of sides which cannot be sides of triangle,
As we know that " Sum of two sides is always greater than the third side "
If any option does not follow the above postulate that will be our required answer :
D) 21 m, 6 m, 10 m
So, 21 m, 6 m, 10 m cannot be the length of any triangle as it does not satisfy the above mentioned postulate .

In the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College. To see whether or not the proportions have changed, a sample of 300 students was taken. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. The calculated value for the test statistic equals
Answer:
The test statistic for Business College is -0.9944
The test statistic for Liberal Arts College is 1.1483
The test statistic for Education College is 0
Step-by-step explanation:
The percentage of ABC University college students in
Business College = 35%
Liberal Arts College = 35%
Education College = 30%
The number of students in the sample = 300 students
In the sample, the number of students in;
Business College = 90
Liberal Arts College = 120
Education College = 90
Therefore;
The percentage of Business College students = 90/300 × 100 = 30%
The percentage of Liberal Arts College, = 120/300 × 100 = 40%
The percentage of Education College, [tex]\hat p[/tex] = 90/300 × 100 = 30%
The test statistic for the difference in two proportions is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]
Where;
[tex]\hat p[/tex] = The sample proportion
p = The population proportion
q = 1 - p
n = The sample size
The test statistic for Business College is;
[tex]z=\dfrac{0.3-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{90}}} \approx -0.9944[/tex]
The test statistic for Liberal Arts College is;
[tex]z=\dfrac{0.4-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{120}}} \approx 1.1483[/tex]
The test statistic for Education College is;
[tex]z=\dfrac{0.3-0.3}{\sqrt{\dfrac{0.3 \times 0.70}{120}}} \approx 0[/tex]
Answer:
Using the Chi-Square test we find test statistic equals 4.29
Step-by-step explanation:
Start by calculating the expected value:
35% Business College = 0.35 x 300 = 105
35% Liberal Arts College = 0.35 x 300 = 105
30% Education College = 0.3 x 300 = 90
Use the Chi-Square Test:

Answer:
There are 16 integers between -3.92 and 12.4
Step-by-step explanation:
If we want to find the integers between two numbers we just need to subtract the integer numbers of the interval.
The integer interval will be:
[tex][-3,12][/tex]
Now, we subtract them:
[tex]12-(-3)=12+3=15[/tex]
Let's recall that 0 is an integer
