Three instrument panel designs are being considered. We are interested in pilot response times as a function of these panel designs. Randomly selected pilots are randomly given simulated emergency situations and response times are measured. We are concerned that pilot experience may also influence our results. Analyze the data both including and not including the covariate of experience. Does including the covariate matter in this case? Is there another covariate we should have included?

Work out the height of this cone

Answers

Answer:20 cm

Step-by-step explanation:

Volume of cone=540π

Radius=r=9

Volume of cone=1/3 x π x r^2 x h

540π=1/3 x π x 9^2 x h

540π=1/3 x π x 9 x 9 x h

540π=(1xπx9x9xh)/3

540π=(81πh)/3

540π=27πh

Divide both sides by 27π

540π/27π=(27πh)/27π

20=h

h=20

Height =20 cm

A standard 52-card deck has four 13-card suits: diamonds, hearts, clubs, and spades. the diamonds and hearts are red, and the clubs and spades are black. each 13-card suit contains cards numbered from 2 to 10, a jack, a queen, a king, and an ace. an experiment consists of drawing 1 card from the standard deck. find the probability of drawing a black king of heartsblack king of hearts.

Answers

The probability of getting a black king of hearts is 1/52

From the question, we have:

The number of cards in a standard deck, n = 52

Black king of heart, r = 1

The probability of getting a black king of hearts is the quotient of the number of black king of heart and the total number of cards in the deck.

So, we have:

p = 1/52

Hence, the probability of getting a black king of hearts is 1/52
