Adding to the variable (x+3) shifts the graph left 3 units, adding a constant shifts the graph upwards, in this case 4 units.

we know that

f(x)=x^{2} \\g(x)=(x+3)^{2}+4

the vertex in the function f(x) is the point (0,0)

the vertex in the function g(x) is the point (-3,4)

so

the rule of the transformation that occurs from  f(x) to g(x) is

(x,y)--------> (x-3,y+4)

that means

3 units left and 4 units up

therefore

<u>the answer is the option</u>

left 3, up 4

Based on historical data, your manager believes that 39% of the company's orders come from first-time customers. A random sample
Irina-Kira [14]

Answer:

z= \frac{0.21- 0.39}{0.0373}= -4.829

z= \frac{0.32- 0.39}{0.0373}=-1.877

And we can find the probability with this difference:

P(-4.829

Step-by-step explanation:

For this case we have the following info given:

n = 171 represent the sample size

p =0.39 the proportion of interest

We want to find the following probability:

P( 0.21 < \hat p < 0.32)

We can use the normal approximation for this case since np >10 and n (1-p) >10

For this case we know that the distribution for the sample proportion is given by:

\hat p \sim N( p , \sqrt{\frac{p (1-p)}{n}} )

And we can use the following parameters:

\mu_{\hat p}= 0.39

\sigma_{\hat p} =\sqrt{\frac{0.39*(1-0.39)}{171}}= 0.0373

And we can apply the z score formula given by:

z = \frac{p \\mu_{\hat p}}{\sigma_{\hat p}}

And using this formula we got:

z= \frac{0.21- 0.39}{0.0373}= -4.829

z= \frac{0.32- 0.39}{0.0373}=-1.877

And we can find the probability with this difference:

P(-4.829
