There are four colors in a bag containing 500 plastic chips. It is known that 28% of the chips are green. On average, how many chips from a random sample of 50 (with replacement) would be expected to be green

14

Step-by-step explanation:

Total number of chips = 500

Percentage of green chips = 28%

P(green chips) = 0.28

Expected number of green chips from a simple of 50

Sample size, n = 50

p of green chips = 0.28

Recall:

Mean, m = n*p

Expected number of green chips = 50 * 0.28 = 14

14 green chips

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
