Answer:

C. 5 to 10 days

Step-by-step explanation:

If she drove 100 miles per day, then

1000/100 = 10

it took her 10 days.

If she drove 200 miles per day, then

1000/200 = 5

it took her 5 days.

Since she drove between 100 miles and 200 miles per days,

it took her from 5 to 10 days.

Answer: C. 5 to 10 days

The ability to find a job after graduation is very important to GSU students as it is to the students at most colleges and unive

Answer: (0.8468, 0.8764)

Step-by-step explanation:

Formula to find the confidence interval for population proportion is given by :-

$\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

, where $\hat{p}$ = sample proportion.

z* = Critical value

n= Sample size.

Let p be the true proportion of GSU Juniors who believe that they will, immediately, be employed after graduation.

Given : Sample size = 3597

Number of students believe that they will find a job immediately after graduation= 3099

Then, $\hat{p}=\dfrac{3099}{3597}\approx0.8616$

We know that , Critical value for 99% confidence interval = z*=2.576 (By z-table)

The 99 % confidence interval for the proportion of GSU Juniors who believe that they will, immediately, be employed after graduation will be

$0.8616\pm(2.576)\sqrt{\dfrac{0.8616(1-0.8616)}{3597}}$

$0.8616\pm (2.576)\sqrt{0.0000331513594662}$

$\approx0.8616\pm0.0148\\\\=(0.8616-0.0148,\ 0.8616+0.0148)=(0.8468,\ 0.8764)$

Hence, the 99 % confidence interval for the proportion of GSU Juniors who believe that they will, immediately, be employed after graduation. = (0.8468, 0.8764)

Which expression can be simplified to find the slope of the trend line in the scatterplot? On a coordinate plane, a line goes th

Goryan [66]

Answer:

(A) $\dfrac{24-79}{12-2}$

Step-by-step explanation:

Given the trend line which goes through (2, 79) and (12, 24).

$Slope, m=\dfrac{y_2-y_1}{x_2-x_1} \\x_1=2, y_1=79,x_2=12, y_2=24\\$Therefore$:\\\\m=\dfrac{24-79}{12-2}$

The equation which can be simplified to find the slope of the trend line in the scatterplot is $\dfrac{24-79}{12-2}$

The correct option is A.
