Answer:15 min=37.5 gal., 20 min=50 gal.
Step-by-step explanation:
Hey! This question can be tricky at first look. So what we’re going to do first is find 24^-1. This would be .0416 rounded to the thousandths place. We are rounding because it is a repeating decimal and it goes on forever or for a while at least. Now we know that .0416 gallons flow each second.
Next, we will multiply by 60 to find how much flows each minutes. We do this because there are 60 seconds in a minute. We then get 2.5 gallons.
We then multiple by the number of minutes which in this case is 15 and 20.
2.5x15= 37.5 gallons
2.5x20=50 gallons

Stream ecologists are interested in the number of distinct organisms found in streams and whether or not differences exist based on geography. Separate random samples are obtained from sites in Northeastern and Southeastern streams, and the number of distinct organisms is recorded. They are given as separate stemplots for Northeastern and Southeastern streams.

What is the sample size obtained from Southeastern?
Answer:
14
Step-by-step explanation:
Given

Required
The sample size for Southeastern
The stem plot for southeastern is:
[tex]Stem | Leaf[/tex]
[tex]0 | 5\ 5\ 7\ 8[/tex]
[tex]1 | 1\ 2\ 3\ 5\ 9\ 9[/tex]
[tex]2 |2\ 7[/tex]
[tex]3 | 3[/tex]
[tex]4 | 1[/tex]
[tex]5 |[/tex]
To get the sample size, we simply count the leaves
The leaves are:
[tex]Leaves = \{5, 5, 7, 8, 1, 2, 3, 5, 9 ,9,2,7,3,1\}[/tex]
The number of leaves is:
[tex]n(Leaves) = 14[/tex]
Hence, the sample size is 14

A consumer advocacy group wants to determine whether there is a difference between the proportions of the two leading automobile models that need major repairs (more than $500) within two years of their purchase. A sample of 400 two-year owners of model 1 is contacted, and a sample of 500 two-year owners of model 2 is contacted. The numbers x1 and x2 of owners who report that their cars needed major repairs within the first two years are 53 and 78, respectively. What is the p-value of the appropriate test of hypotheses
Answer:
The answer is "0.3206".
Step-by-step explanation:
[tex]H_0: p_1 = p_2\\\\H_a: p_1 \neq p_2\\\\\hat{p_1} = \frac{X_1}{N_1} = \frac{53}{400} = 0.1325\\\\\hat{p_1}= \frac{X_2}{N_2} = \frac{78}{500}= 0.156\\\\\hat{p} = \frac{(X_1 + X_2)}{(N_1 + N_2)} = \frac{(53+78)}{(400+500)} = 0.1456[/tex]

The square of p varies inversely as q. When Q=6 p=4
What is the value of q when
P = 12
A. 2/3
B. 3/2
C. 2
D. 18
Answer:
A
Step-by-step explanation:
Given p² varies inversely as q then the equation relating them is
p² = [tex]\frac{k}{q}[/tex] ← k is the constant of variation
To find use the condition when q = 6, p = 4 , then
4² = [tex]\frac{k}{6}[/tex]
16 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
96 = k
p² = [tex]\frac{96}{q}[/tex] ← equation of variation
When p = 12 , then
12² = [tex]\frac{96}{q}[/tex] ( multiply both sides by q )
144q = 96 ( divide both sides by 144 )
q = [tex]\frac{96}{144}[/tex] = [tex]\frac{2}{3}[/tex] → A

Find the value of x.A.66B.58C.68D.32
Answer:
x = 66
Step-by-step explanation:
Remark
98 is an exterior angle. Exterior angles are the sum of the two remote interior angles. The remote interior angles have 2 properties
They are not supplementary to the exterior angleThey each share a side with the remote interior angle.It's much easier just to make an equation.
x + 32 = 98 Subtract 32 from each side
- 32 -32
x = 66

mZR = 110 and mZS = 80. Find mZT. The diagram is not to scale.
Answer:
d. 90°
Step-by-step explanation:
Recall: based on the properties of a kite, the angles where the two unequal sides meet are congruent, this means that m<S = m<U.
Also, the sum of all angles of a kite = 360°
Therefore:
m<S + m<U + m<R + m<T = 360°
m<S = m<U = 80°
m<R = 110°
Substitute
80° + 80° + 110° + m<T = 360°
270° + m<T = 360°
Subtract 270° from each side
m<T = 360° - 270° = 90°

6. Let the function g be defined by g(x) = x4 – x3 – 9x2 + 9x. It is given that
x = 1 is a zero of the function g. Which of the following best represents the fully
factored form of the function g?
Answer:
A
Step-by-step explanation:
There is an x in all for terms that means that x = 0 is one of the factors and H is incorrect.
One of the remaining factors is x^2 - 9 which factors into (x - 3)(x + 3)
You are told that x = 1 is a zero which means x - 1 is a factor.
The answer is g(x) = x (x - 3)(x + 3) (x - 1) which is A
Two sides of a parallelogram are 730 feet and 970 feet. The measure of the angle between these sides is 151°. Find the area of the parallelogram to the nearest square foot.
Answer:
343294 feets
Step-by-step explanation:
We Obtian the height:
Using trigonometry :
Sin151 = h / 730
0.4848096 = h / 730
h = 353.91102
Area of parallelogram = base * height
Base = 970 feets ; height = 353.91102 feets
Area = 970 * 353.91102
= 343293.6894 feets
= 343294 feets

Answer:
Option A.
(x + 8) + (–4x + 31) / (x² + 2x + 1)
Step-by-step explanation:
x³ + 10x² + 13x + 39 / x² + 2x + 1
To rewrite the above expression in the form q(x) + r(x) / b(x), we shall simply divide (x³ + 10x² + 13x + 39) by
(x² + 2x + 1)
Please see attached photo for explanation
From the attached photo,
the quotient q(x) = x + 8
The remainder r(x) = –4x + 31
Divisor b(x) = x² + 2x + 1
Thus,
x³ + 10x² + 13x + 39 / x² + 2x + 1
= (x + 8) + (–4x + 31) / (x² + 2x + 1)
