It means, Whatever the Value of x is, add 2 to it. ( example x=5, it would be 5=2=7

so y-7)

Answer:

a = ± 2

Step-by-step explanation:

Let the scale factor is k.

Then the transformation is:

(x, y) → (kx, ky)

We have:

(x, y) → (12x, 3a²y)

The scale factor is k = 12, find the value of a:

3a² = 12
a² = 4
a = √4
a = ± 2

Answer: 0.6368

Step-by-step explanation:

Given : The proportion of z-test for population mean : $\hat{p}= 0.80$

Sample size : $n=45$

We assume that this is normally distributed.

The test statistic for population proportion :-

$z=\dfrac{\hat{p}-p_0}{\sqrt{\dfrac{p_0(1-p_0)}{n}}}$

Now, for $p_0=0.82$ , we have

$z=\dfrac{0.80-0.82}{\sqrt{\dfrac{0.82(1-0.82)}{45}}}\\\\\approx-0.35$

By using the standard normal distribution table , the probability that at least 82% of the surveyed students will be attending college will be :-

$P(p\geq0.82)=P(z\geq-0.35)\\\\=1-P(z$

Hence, the probability that at least 82% of the surveyed students will be attending college = 0.6368
