The three units upward shift is denoted by +3 outside of the parenthesis and horizontal shift to the right is represented by -2 inside the parenthesis.
The answer is C.

The graph of y = x² ( the parent function ) is shifted vertically 3 units up and horizontally 2 units right:
y = ( x - h )² + k, where: h = 2 and k = 3
Answer:
C ) y = ( x - 2 )² + 3

Answer:

1. x=11/4

Step-by-step explanation:

$\frac{3}{5} x - \frac{3}{4} = \frac{9}{10}$

u should x 20 then u will get

$12x - 15 = 18$

$12x = 18 + 15$

$12x = 33$

$x = \frac{33}{12}$

$x = \frac{11}{4}$

You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard devia

gtnhenbr [62]

Answer:

$n=(\frac{2.58(58.2)}{1})^2 =22546.82 \approx 22547$

So the answer for this case would be n=22547 rounded up to the nearest integer

Step-by-step explanation:

Let's define some notation

$\bar X$ represent the sample mean

$\mu$ population mean (variable of interest)

$\sigma=58.2$ represent the population standard deviation

n represent the sample size

$ME =1$ represent the margin of error desire

The margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (a)

And on this case we have that ME =+1 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=(\frac{z_{\alpha/2} \sigma}{ME})^2$ (b)

The critical value for 99% of confidence interval now can be founded using the normal distribution. The significance would be $\alpha=0.01$ and the critical value $z_{\alpha/2}=2.58$ , replacing into formula (b) we got:

$n=(\frac{2.58(58.2)}{1})^2 =22546.82 \approx 22547$

So the answer for this case would be n=22547 rounded up to the nearest integer
