Step-by-step explanation:

120÷40=3

Answer:

300

Step-by-step explanation:

The total number of desserts is x. we don't know what it is.

40% of all the desserts are cookies.

That is 40% of x.

We are told that 120 of the desserts are cookies.

That means that 40% of all desserts amount to 120.

40% of x = 120

0.4x = 120

Divide both sides by 0.4

0.4x/0.4 = 120/0.4

x = 300

Answer: In all there are 300 desserts.

Answer: 0.0548

Step-by-step explanation:

Given, A research study investigated differences between male and female students. Based on the study results, we can assume the population mean and standard deviation for the GPA of male students are µ = 3.5 and σ = 0.05.

Let $\overline{X}$ represents the sample mean GPA for each student.

Then, the probability that the random sample of 100 male students has a mean GPA greater than 3.42:

$P(\overline{X}>3.42)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{3.42-3.5}{\dfrac{0.5}{\sqrt{100}}})\\\\=P(Z>\dfrac{-0.08}{\dfrac{0.5}{10}})\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=P(Z>1.6)\\\\=1-P(Z$
