V125BC [204]

Answer:

<u>Given </u>

  • f(x) = 3 + 6x

A

<u>Find the inverse of f(x):</u>

  • x = 3 + 6f⁻¹(x)
  • 6f⁻¹(x) = x - 3
  • f⁻¹(x) = (x - 3) / 6

B

  • f · f⁻¹( ∛5/6) =
  • f( f⁻¹( ∛5/6)) =
  • f((∛5/6 - 3)/6) =
  • 3 + 6((∛5/6 - 3)/6) =
  • 3 + ∛5/6 - 3 =
  • ∛5/6

C

  • f · f⁻¹(x) =
  • f(f⁻¹(x)) =
  • f((x - 3)/6) =
  • 3 + 6(x - 3)/6 =
  • 3 + x - 3 =
  • x

oksian1 [2.3K]

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

hence, the required probability is 0.0548.
