hello!

if there are currently 900 students enrolled and it would be increased by 60 students in the next 13 years, the equation would be: 900 + 60(13) = 1,680 students after 13 years

if this helps, click “thanks” :)

Answer:

1,680

Step-by-step explanation:

If the population is increasing by 60 for the next 13 years, we must multiply 60 and 13 to get 780.

Then, we just add 780 to the original population to get 1,680!

A 2015 Gallup poll of 1,627 adults found that only 22% felt fully engaged with their mortgage provider.
Zigmanuir [339]

Answer: (20.0\%,24.0\%)

Step-by-step explanation:

Given, A 2015 Gallup poll of 1,627 adults found that only 22% felt fully engaged with their mortgage provider.

Here , 1,627 adults are determining the sample.

Thus, sample size : n = 1627

Also, the sample proportion of adults felt fully engaged with their mortgage provider are \hat{p}=22\%=0.22

for 95% confidence level , critical z-value =1.96

Then , the 95% confidence interval would be :-

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

Substituting values , we get

0.22\pm 1.96(\sqrt{\dfrac{0.22(1-0.22)}{1627}})\\\\=0.22\pm 1.96\sqrt{\dfrac{0.22\times0.78}{1627}}\\\\\approx0.22\pm0.0201\\\\=(0.22-0.0201,\ 0.22+0.0201)\\\\=(0.1999,\ 0.2401)\approx(20.0\%,24.0\%)

Hence, the required 95% confidence interval using only 1 decimal : (20.0\%,24.0\%) .

Help me fast!! I need to get a 90 on it
QveST [7]

Answer:

-7/2

Step-by-step explanation:

Slope equals rise (vertical or y axis) over run (horizontal or x axis).  So you need to find two points on this line that cross directly where the grid lines cross.  If you look closely, the line seems to cross directly at ( -6, 3 ) and again at ( -4, -4).  So the rise values (y axis) are 3 and -4 which is a total of 7 units apart.

The run values are -6 and -4 which is a total of 2 units apart.

So your slope with be 7/2 but since it slopes downward to the right, it is a negative slope.

The answer would be negative 7/2
