The answer to your question is below

Step-by-step explanation:

First, determine the kind of lines.

The Pink line must be dotted because of the "≤" sign.

The Yellow line must be dotted because of the ">" sign.

Then, choose the shaded areas

For the pink line, we need the lower part.

For the yellow line, we need the right part

Choose the area where both areas cross.

It is the lower and right area.

As a manager for an advertising company, you must plan a campaign designed to increase Twitter usage. A recent survey suggests t

kolbaska11 [484]

Given:
Sample proportion = 85% = 0.85.
Confidence level (CL) = 90%.
Confidence interval (CI) $\hat{p} \pm z^{*} \sqrt{ \frac{\hat{p}(1-\hat{p})}{n} } \\ where \\ n=sample\, size \\ z^{*}=1.645 \, at \, 90\% \, CL$

We want the confidence interval to be 5% or 0.05. Therefore
$0.85 - 1.645 \sqrt{ \frac{0.85(1-0.85)}{n} }=0.05 \\ 0.85 - \frac{0.5874}{ \sqrt{n} } =0.05 \\ \frac{0.5874}{ \sqrt{n} }=0.8 \\ \sqrt{n} = .7342 \\ n=0.54$

Because this number is less than 1, a default sample size of 30 (for the normal distribution) is recommended.

the sum of the digits of a certain two-digits number is 7.Reversing its digits increases the number by 9.What is the number

rusak2 [61]

Unit digit=y
tens digit=x
the number: 10x+y

We suggest this system of equations:
x+y=7
(10y+x)=(10x+y)+9
we solve it by substitution method.
x=7-y
10y+(7-y)=(10(7-y)+y)+9
9y+7=70-10y+y+9
9y+10y-y=70+9-7
18y=72
y=72/18=4

x=7-y
x=7-4=3

number=10x+y=10*3+4=30+4=34

solution: the number: 34

To check:
3+4=7
43=34+9
