Answer:
110°
Step-by-step explanation:
128°+40°+82°+x°= 360°
so 250°+x°=360°
x°=360°-250°
x°=110°

Answer:
r=14cm
Step-by-step explanation:
Curved Surface area of a cylinder=484cm²
Height=5.5cm
r=?
Curved Surface Area=2πrh
484=2×3.142×r×5.5
484=34.56r
r=484/34.56
r=14cm

The probability that the participant was a nonsmoker is 25%.
<h3><u>Probability</u> </h3>
Given that at the beginning of a certain study of a group of persons, 15% were classified as heavy smokers, 30% as light smokers, and 55% as nonsmokers, and in the five-year study, it was determined that the death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively, to calculate, if a randomly selected participant died over the five-year period, the probability that the participant was a nonsmoker, the following calculation must be performed:
- 15 x 5 = 75
- 30 x 3 = 90
- 55 = 55
- 55 + 90 + 75 = 220
- 220 = 100
- 55 = X
- 55 x 100 / 220 = x
- 5500 / 220 = X
- 25 = X
Therefore, the probability that the participant was a nonsmoker is 25%.
