(01.05) Use the graph below to answer this question: graph of line going through negative 1, 4 and 2, 0 Find the average rate of
dsp73

1) Find the graph of a line passing through (-1, 4) and (2, 0).

The slope of two points can be determined by dividing the difference of y-values by the difference of x-values:

\frac{4-0}{-1-2} =\frac{4}{-3}

The slope of this equation is -4/3. Inputting this into the slope-intercept form of an equation, we get:

y=\frac{-4}{3} x+b

To find b, substitute x and y for one of the given coordinate pairs:

0 = (-4/3)(2) + b

0 = -8/3 + b

8/3 = b

Substitute the b value into the equation to finish the line:

y=\frac{-4}{3} x+\frac{8}{3}

I really need help, someone please help me
Hoochie [10]

Answer:

18.84 meters.

Step-by-step explanation:

The formula for a circle is πr^2.

πr^2 = 28.26

3.14 * r^2 = 28.26

r^2 = 9

r = plus or minus 3.

But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters.

The formula for the circumference is 2πr.

2 * 3.14 * 3 = 6 * 3.14 = 18.84.

So, the circumference of the circle is 18.84 meters.

Hope this helps!

Which table shows a proportional relationship
yarga [219]

<h3>stop using this website just for answers, it's cheating, and it doesn't help you learn anything. Instead, you SHOULD ask how to figure out the question you're asking.</h3><h3>For example: how do I figure out which table represents a proportional relationship?</h3>

answer: look for a common Multiple

The answer is option two, "S" represents one and "R" represents five

Suppose a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101
stepan [7]

Answer:

101, 3, 0.025, 0.7416

Step-by-step explanation:

Given that  a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.

As per central limit theorem we have

a) Mean of sample mean = E(\bar x) =\\ \mu =101

Std deviation of sample mean = \frac{\sigma}{\sqrt{n} } =3

Mean = 101

Std dev =3.00

b) P(\bar x >107) = P(Z>\frac{107-101}{3} )\\= P(Z>2) = 0.025

c) the probability that the sample mean deviates from the population mean μ = 101 by no more than 4.

=P(|\bar x-101|) \leq 4\\= P(|z|\leq 1.13)\\= 2(0.3708)\\=0.7416
