The ages of the 5 officers for a school club are 18, 18, 17, 16, and 15. The proportion of officers who are younger than 18 is 0.6. The table displays all possible samples of size 2 and the corresponding proportion for each sample.
Sample n = 2 18, 18 18, 17 18, 17 18, 16 18, 16 18, 15 18, 15 17, 16 17, 15 16, 15

Using the proportions in the table, is the sample proportion an unbiased estimator?
Yes, the sample proportions are calculated using samples from the population.
Yes, the mean of the sample proportions is 0.6, which is the same as the population proportion.
No, 0.6 is not one of the possible sample proportions.
No, 70% of the sample proportions are less than or equal to 0.5.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

mariah is studying the life cycle of the monarch butterfly. she must choose one stage in the cycle to present in science class: egg, caterpillar, chrysalis, or adult. she plans to make her choice randomly using a custom spinner divided into four sections. first, however, she spins the spinner 50 times to see the frequencies it generates.

stage times landed on

egg 10

caterpillar 12

chrysalis 15

adult 13
