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 : $(20.0\%,24.0\%)$ .

Which transformation is a isometry?

Lady bird [3.3K]

Answer:

A. The two triangles.

Step-by-step explanation:

Isometry can be divided into two words: iso = same and metry = measure

So, isometry means "same measure".

In this case, that means the transformation didn't change the measures of the object.

In B, they kept the same shape, but not the same side.

In C, you can see the figure has been transformed,.

What is the equation of the graphed linear model?<br><br> y = ? x + ?

miss Akunina [59]

Use slope intercept form for equation, which is y = mx +b. m is slope and b is the y-intercept.

Find slope by change in y over change in x. So pick two points, for example (0, 24) and (2, 20). Slope (m) will be
(y2-y1)/(x2-x1)
= (24-20)/(0-2)
= 4/-2
m = -2

Y-intercept is 24.

Equation is y = -2x + 24
