A cylindrical water towers has a diameter of 15 meters and a height of 5 meters. About how many gallons of water can the gallon contain?
Answer:
233445.54 gallons
Step-by-step explanation:
Given data
Diameter= 15m
Radius= 7.5m
Height= 5m
Let us first find the volume
the volume of a cylinder is given as
V= πr^2h
substitute
V= 3.142*7.5^2*5
V= 3.142*56.25*5
V=883.6875 m^3
Hence the volume in gallons is
233445.54 gallons (from conversion tables)

What is the probability that someone in your class wants the New England Patriots to win
Answer:
Step-by-step explanation:
It all depends on how many people are in your class.
To calculate probability
Determine a single event with a single outcome.
Identify the total number of outcomes that can occur.
Divide the number of events by the number of possible outcomes.
To determine the probability, Use the formula
What is the formula of probability?
P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
P(A | B) = P(A∩B) / P(B)

What is the volume of the rectangular prism?
9514 1404 393
Answer:
17 7/9 yd³
Step-by-step explanation:
The volume is the product of the dimensions.
V = LWH
V = (3 1/3 yd)(2 2/3 yd)(2 yd) = (10/3)(8/3)(2) yd³ = 160/9 yd³ = 17 7/9 yd³
__
Additional comment
You can guess the correct answer with a couple of estimates.
volume is greater than (3)(2)(2) = 12 . . . . rounding down to integer
volume is less than (3 1/3)(3)(2) = 20 . . . . rounding 2 2/3 up to 3
Based on the way these numbers are rounded, the volume is closer to 20 than to 12. This strongly suggests that 17 7/9 is the correct answer.
The difference between the highest and lowest single game point totals for the MIDDLE HALF of the data is ______ points less for Joe's data than Sam's data. Therefore, the MIDDLE HALF of Joe's single game point totals are less varied than Sam's.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required data to answer the question are missing.
However, the interpretation of the question is to determine the interquartile range (IQR) of a certain dataset.
Then get the difference between the calculated IQR & Joe's data and also the difference between the calculated IQR & Sam's data
Then, make comparison
To do this, I will use the following assumed datasets.
[tex]Data: 62, 63, 64, 64, 70, 72, 76, 77, 81, 81[/tex]
IQR is calculated as:
[tex]IQR = Q_3 - Q_1[/tex]
[tex]Q_3[/tex] is [tex]the\ median[/tex] of the upper half
[tex]Q_1[/tex] is [tex]the\ median[/tex] of the lower half
For Joe, we have:
[tex]Lower\ half: 62, 63, 64, 64, 70[/tex]
[tex]Upper\ half: 72, 76, 77, 81, 81[/tex]
The median is then calculated as:
[tex]M = \frac{N + 1}{2}[/tex]
For, the lower half:
[tex]Q_1 = \frac{5 + 1}{2} = \frac{6}{2} = 3rd[/tex]
So:
[tex]Q_1 = 64[/tex]
For the upper half:
[tex]Q_3 = \frac{5 + 1}{2} = \frac{6}{2} = 3rd[/tex]
So:
[tex]Q_3 = 77[/tex]
When the same process is applied to Sam's data,
[tex]Q_1 = 52[/tex]
[tex]Q_3 = 58[/tex]
[tex]IQR = Q_3 - Q_1[/tex]
[tex]IQR = 77 - 64[/tex]
[tex]IQR = 13[/tex]
Assume that:
[tex]Joe = 60[/tex]
[tex]Sam = 65[/tex]
[tex]Joe - IQR = 60 - 13 = 47[/tex]
[tex]Sam- IQR = 65- 13 = 52[/tex]
Hence, the IQR is 47 points less for Joe's data than Sam's
what is the quotient of 13 divided by 8

In ΔKLM, k = 76 inches, l = 30 inches and m=69 inches. Find the measure of ∠M to the nearest degree. pleseeeeee
Answer: 65
Step-by-step explanation:
Measure of ∠M to the nearest degree is [tex]65^{0}[/tex].
What is law of cosine?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.
Given
k = 76 inches
l = 30 inches
m = 69 inches
From the law of cosines
Cos <M = [tex]\frac{k^{2} +l^{2} -m^{2} }{2.k.l}[/tex]
Cos <M = [tex]\frac{76^{2} +30^{2} -69^{2} }{2.76.30}[/tex]
Cos <M = [tex]\frac{1915}{4560}[/tex]
Cos <M = 0.42
<M = [tex]cos^{-1} (0.42)[/tex]
<M ≈ [tex]65^{0}[/tex]
Hence, measure of ∠M to the nearest degree is [tex]65^{0}[/tex].

A scientist planted seeds in 4 sections of soil for an experiment. Not all of the
seeds grew into plants. After 20 days, the scientist counted the number of
plants in each of the 4 sections. The results are shown in the table.
• Use the data in the table to determine approximately how many plants
grew per square foot.
• Explain or show how you determined your approximation.
• Let y be the number of plants expected to grow in x square feet. Write an
equation the scientist could use to model the relationship between y and x.
Answer:
I think you would multiply 20 × 4 and the answer would be 80 that the scientist counted the number of plants in each 4 sections after 20 days.
The number of plants per square foot will be; 48.
Given that scientist planted seeds in 4 sections of soil for an experiment. Not all of the seeds grew into plants. After 20 days, the scientist counted the number of plants in each of the 4 sections.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
The number of plants per square foot:
= (25 × 13) + (100 × 38) + (125 × 47) + (150 × 62) / (25 + 100 + 125 + 150)
= (325 + 3800 + 5875 + 9300) / 400
= 48.25
Thus, it was illustrated by the number of plants and size of sections.
Thus, the number of plants per square foot will be 48.
