What is the rate of change of height?The rate of change of height represents the change in height with time.
Here, the given graph represents:
For some time the water level of the Humpy Dam doesn't change.
After a heavy rain spell, the water level rises, increasing at a constant rate.
After the rain subsides, it levels off again.
Here, the x-axis represents time and the y-axis represents the height of the water behind the dam.
The water height behind the dam was constant for a certain period. After rainfall, the height of the water increased at a constant rate. When the rain stopped, the water height behind the dam is constant at a newer height.

Answers
Answer:
[tex]17.5\ \text{feet}[/tex]
Step-by-step explanation:
A bookcase has 5 bookshelves. Each bookshelf is 42 inches long.
Total bookshelf length in the book case = [tex]5\times 42=210\ \text{inches}[/tex]
[tex]1\ \text{feet}=12\ \text{inches}\\\Rightarrow 1\ \text{inch}=\dfrac{1}{12}\ \text{feet}[/tex]
[tex]210\ \text{feet}=210\times \dfrac{1}{12}=17.5\ \text{feet}[/tex]
The bookcase has a total shelf space of [tex]17.5\ \text{feet}[/tex].
*One bookshelf has a space of [tex]\dfrac{42}{12}=3.5\ \text{feet}[/tex].

Let E be the event that a corn crop has an infestation of ear worms, and let B be the event that a corn crop has an infestation of corn borers. Suppose that P(E) = 0.24, P(B) = 0.16, and P(E and B) = 0.13. Find the probability that a corn crop has either an ear worm infestation, a corn borer infestation, or both.
a. 0.53
b. 0.13
c. 0.6
d. 0.27
Answers
Answer:
d. 0.27
Step-by-step explanation:
Calculation to determine the probability that a corn crop has either an ear worm infestation, a corn borer infestation or both
Using this formula
P(E U B) = P(E) +P(B) -P(E n B)
Let plug in the formula
P(E U B) =0.24 + 0.16 -0.13
P(E U B)=0.27
Therefore the probability that a corn crop has either an ear worm infestation, a corn borer infestation or both will be 0.27

Quadrilateral means four sided shape, so automatically, because a square has 4 sides, you know it is a quadrilateral.

The value of a school bus reduces from $512000 to $343000in 3 years. Find the
uniform rate of depreciation per annum (R).
Answers
Answer:
The uniform rate of depreciation is $56,333 per year, or 11% per year.
Step-by-step explanation:
Rate of Depreciation
If some object has a certain value P and after some time t its value decreases to Q, the rate of depreciation is a measure of how much its value changed per unit time.
It can be calculated as:
[tex]\displaystyle R=\frac{P-Q}{t}[/tex]
It can also be expressed as a percentage, dividing the previous value by P.
The school bus reduces its value from $512,000 to $343,000 in 3 years, thus:
[tex]\displaystyle R=\frac{512,000-343,000}{3}[/tex]
[tex]\displaystyle R=\frac{169,000}{3}[/tex]
R = 56,333 $/year
Expressed as a percentage:
R = 56,333 / 512,000 = 0.11
R = 11%/year
The uniform rate of depreciation is $56,333 per year, or 11% per year.

b)
Four gallons of water weigh 33.4 lb
Find the constant of variation.
Answers
Answer:
a) 62.625 lb
b) 8.35
Step-by-step explanation:
a)
Use a proportion.
4 gal is to 33.4 lb as 7.5 gal is to x lb.
4/33.4 = 7.5/x
4x = 33.4 * 7.5
4x = 250.5
x = 62.625
Answer: 62.625 lb
b)
33.4/4 = 8.35
1) Cost of 7.5 gallons of water = 62.63 lb
2) The constant of variation = 8.35 lb
We have to given that,
1) Cost of 4 gallons = 33.4 lb
2) And, Cost of 4 gallon of water = 33.4 lb
Hence, We can simplify it as,
1) Since, Cost of 4 gallons = 33.4 lb
Hence, Cost of 7.5 gallons = 7.5 × 33.4 / 4 lb
= 62.63 lb
2) Since, Cost of 4 gallon of water = 33.4 lb
Hence, the constant of variation = 33.4 / 4
= 8.35

Find the sample size required to estimate the percentage of college students who take a statistics course. Assume that we want 95% confidence that the proportion from the sample is within four percentage points of the true population percentage. Round the answer to the next larger whole number.
Answers
Answer:
The sample size is [tex]n = 600 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is E = 4% = 0.04
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Since the sample proportion (point estimate of the population proportion was not give we will assume it to be )
[tex]\^ p = 0.5[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n = [\frac{1.96}{0.04} ]^2 * 0.5 (1 - 0.5 ) [/tex]
=> [tex]n = 600 [/tex]
