What is the rate of change of the function represented by the table?

Alexeev081 [22]

Rate of change, or slope, or rise over run, or ‘m’ is the difference between a pair of y-coordinates over the difference between a pair of x-coordinates.

The formula for rate of change or slope is:

m=(y2-y1) / (x2-x1)

All we have to do is take two pairs of coordinates from the table and solve for the slope (m).

Let’s just choose the first two coordinates: (1, 5) and (2, 5).

m=(5-5) / (2-1)

m=(0)/(1)

m=0

So, the rate of change is 0; there is no rate of change. There is 0 rise per 1 unit of run.

I’ll give brainliest!

DochEvi [55]

Step-by-step explanation:

Line L passes through point (0,2) and (4,0)

If you want to find the gradient of Line L, you can use this formula :

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

$m = \frac{0 - 2}{4 - 0}$

$m = \frac{ - 2}{4}$

$m = - \frac{1}{2}$

Many people who bought Z-Game gaming systems over the holidays have complained that the systems they purchased were defective. I

Bas_tet [7]

Answer:

The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022

Step-by-step explanation:

Upper Limit for 95% Confidence Interval can be calculated using p+ME where

p is the sample proportion of defective gaming systems ( $\frac{18}{1200} = 0.015$ )

ME is the margin of error from the mean

and margin of error (ME) around the mean can be found using the formula

ME= $\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} }$ where

z is the statistic of 95% confidence level (1.96)

p is the sample proportion ( $\frac{18}{1200}=0.015$

N is the sample size (1200)

Using the numbers we get:

ME= $\frac{1.96*\sqrt{0.015*0.985}}{\sqrt{1200} }$ ≈ 0.007

Then upper limit for the population proportion is 0.015+0.007 =0.022

If a = 7, what is the value of the expression 2(a + 8)?

raketka [301]

Answer:

30

Step-by-step explanation:

Substitute X with 7 since X=7 so 2(7+8). Follow order of operations and 7+8=15 and the multiply 15 by 2 to get your final answer 30.
