Answer:

y = 3x - 8

Step-by-step explanation:

Line is passing through the points (2, - 2) & (0, - 8)

Slope of line

$\: m = \frac{ - 8 - ( - 2)}{0 - 2} \\ \\ = \frac{ - 8 + 2}{ - 2} \\ \\ = \frac{ - 6}{ - 2} \\ \\ = 3 \\ \\y-intercept = b = - 8\\ \\equation \: of \: line \: in \:slope \:\\ intrecept \: form \: is \: given \: as \\ \\ y = mx + b \\ \\ y = 3x + ( - 8) \\ \\ \huge \red {y = 3x - 8}$

Ugo [173]

Answer: A. 664

Step-by-step explanation:

Given : A marketing firm is asked to estimate the percent of existing customers who would purchase a "digital upgrade" to their basic cable TV service.

But there is no information regarding the population proportion is mentioned.

Formula to find the samples size , if the prior estimate to the population proportion is unknown :

$n=0.25(\dfrac{z*}{E})^2$

, where E = Margin of error.

z* = Two -tailed critical z-value

We know that critical value for 99% confidence interval = $z*=2.576$ [By z-table]

Margin of error = 0.05

Then, the minimum sample size would become :

$n=0.25(\dfrac{2.576}{0.05})^2$

Simplify,

$n=0.25\times2654.3104=663.5776\approx664$

Thus, the required sample size= 664

Hence, the correct answer is A. 664.

Question 1:
If you know that 3 squares equals 7 circles and the squares are being counted by 3, then continue to count the circle by 3 until you get 25 circles.
Example:
3 Squares : 7 circles
4 squares : 10 circles
5 squares : 13 circles
6 squares : 16 circles
7 squares : 19 circles
8 squares : 22 circles
9 squares : 25 circles Add 9 squares to 3 = 12
You will have 12 squares when continues to count all the way to 25 circles.

Question 2:
Just multiply 14 by 28 and you will get your answer. Which is 3. The missing digit's 3. You can then check by doing 392 ÷ 14 to see if you get 28.
