(9+5i)(9+8i)
81+72i+45i+40i^2 // i^2 is going to be always -1
81+72i+45i+40(-1)
81+72i+45i-40
41+117i

There you go!!!

A multiple choice test has four possible answers for each question. Let X be the number of correct responses in a test of 100 qu

dimulka [17.4K]

Answer:

a. 4.33.

Step-by-step explanation:

If there is only one correct answer out of four alternatives, the expected proportion of correct answers is p =0.25

Sample size (n) = 100 questions

The standard deviation of a proportion 'p' is given by:

$s=\sqrt{\frac{p*(1-p)}{n} }$

Applying the given data:

$s=\sqrt{\frac{0.25*(1-0.25)}{100}}\\s=0.0433$

If X is the number of correct responses in 100 guesses, the standard deviation of X is:

$\sigma = n*s=100*0.0433\\\sigma = 4.33$

The standard deviation of X is 4.33 questions.

Robert has a container in the shape of a cube with an edge length of 6.1 cm. What is the volume of the container?

Setler79 [48]

Since it's a cube all the side lengths are the same. So the calculation would be 6.1x6.1x6.1 or 6.1^3
V=226.981cm^3
V=Length x width x height

Answer:

11,880π in^3

Step-by-step explanation:

The volume of a cylinder = π r^2 h

Large Cylinder V = π * 15^2*40 = 9,000π in^3

Small Cylinder V = π * 12^2 * (60-40) = 2880π in^3

Adding: the total volume of the model = 11,880π in^3
