Answer:
for number 2 the answer is 12 ft
Step-by-step explanation: 252π/7=36π, so r=6. d=r*2=12 ft
The estimated probability for P(H) is 0.17.
<h3>What is Probability ?</h3>
Probability is the stream in mathematics that studies about the likeliness of an event to happen.
It is given that
Total number of times coin is flipped = 30
Total number of times the coin gave heads = 5
Total number of times the coin gave tails=25
The P(H) = Total no. of Heads / Total outcomes
P(H) = 5 / 30
= 1/6
= 0.1666
≈ 0.17
Therefore the estimated probability for P(H) is 0.17.

Probabilit is positive events / total number of events
In this case the positive events is to pick a cap that is not green and the total number is 80 (the number of caps).
The number of not green caps is 80 - 12 = 68.
Then the probability the cap selected will not be green is 68 / 80 = 17 / 20

Answer:
By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 190
Standard deviation = 14
Using the empirical rule, what percentage of the games that Aubree bowls does she score between 148 and 232?
148 = 190 - 3*14
So 148 is 3 standard deviations below the mean.
232 = 190 + 3*14
So 232 is 3 standard deviations above the mean
By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232
