Please get the sample response.

Akimi4 [234]

Answer:Find the amount the store marked up the CDs by.

12.95 * .08 = 1.034 which rounds to 1.04

Add that to the former price.

12.95 + 1.04 = 13.99

Multiply by 4 to see how many 4 CDs cost.

13.99 * 4 = 55.96

Multiply by .1 to see how much the discount is.

55.96 * .1 = 5.596 which rounds to 5.60

Subtract the discount from the original price.

55.96 - 5.6 = 50.36

It costs $50.36 to buy four CDs this year.

The GPA's at RHS are Normally distributed with a mean of 2.8 and a standard deviation of 0.7. Let G = a random student's GPA.

Alja [10]

The value of P(G<2.5) is 14.23%.

What is observation?

The active gathering of data from a primary source is observation. Observation of living things makes use of the senses. Using scientific tools to perceive and record data is another way that observation may be used in science.

The $z$ -score for this observation of 2.30 is:

Z= (2.3-2.8)/0.7=-1.71

The table shows a value of 0.8577 , and because this z-score is negative, this is the proportion greater than a GPA of 2.30. So the proportion less than 2.30 is 1-0.8577 =0.1423 . Expressing it mathematically we have:

$\begin{aligned}P(X \leq 2.7) & =P(Z \leq-1.07) \\& =1-P(Z \geq-1.07) \\& =1-P(Z \leq 1.07) \\& =1-0.8577 \\& =0.1423=14.23 \%\end{aligned}$
