Answer: Choice A) Solar energy; renewable

The image shows panels that convert <u> </u><u>solar energy </u> to electricity. This is an example of using <u> renewable </u> sources.

This is in contrast to something like coal energy which is nonrenewable. Coal is finite and will run out some day, unlike the sun's energy which won't run out any time soon. Sure it will eventually die off in about 5 billion years or so, but that timescale is much longer compared to the amount of coal is left. So this is a benefit to using renewable resources.

The pie chart to the right shows how adults rate their financial shape. Suppose 4 people are chosen at random from a group of 11

vekshin1

Answer:

Step-by-step explanation:

Given that a pie chart shows data as

Excellent 7%

Good 44%

Fair 35%

Poor 13%

Other 1%

If 4 people are chosen at random we find that each person is independent of other and there are two outcomes either excellent or not excellent.

p = Prob for success = p = 7%=0.07

q = Prob for non success = 1-0.07 = 0.93

If x is a random variable representing the excellent persons then X is binomial with n =4, p = 0.07

Required probability = P(X=4)

= $p^4\\=(0.07)^4\\=0.00002401$

The elevation of city A is 72 feet above sea level; the elevation of city C is 24 feet above sea level. The elevation of city D

Elena-2011 [213]

Step-by-step explanation:

Part A:

In math, the word "of" means "multiplied by".

So if the elevation of city D is 1/4 of the elevation of city C, then our equation is 1/4*C, or C/4

Part B:

But we already know that C = 24, so we can just plug in 24 for C in our equation:

24/4 = 6 feet

Explanation: The answer is positive because when you're dividing two positive integers, there's no possible way to get a negative number.

What is the slope of the line that passes through the pair of points (1/3, -1) and ( -2, 9/2)

UkoKoshka [18]

Answer:

$\boxed{m = - \frac{33}{14} }$

.

Step-by-step explanation:

Use the form below

$\boxed{\boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }}$

Where

$m$ is a slope
$(x_1,~y_1)$ and $(x_2,~y_2)$ are the point of the line

.

So, the slope is

$(\frac{1}{3} ,~ -1) \to x_1 = \frac{1}{3} ~and~y_1 = -1$

$(-2,~ \frac{9}{2} ) \to x_2 = -2~and~y_2 = \frac{9}{2}$

.

$m = \frac{\frac{9}{2} -(-1)}{-2-\frac{1}{3} }$

$m = \frac{\frac{11}{2} }{\frac{-7}{3} }$

$m = \frac{11}{2} \div (-\frac{7}{3} )$

$m = \frac{11}{2} \times (-\frac{3}{7} )$

$m = - \frac{33}{14}$

.

Happy to help:)
