Answer:
200 feet
Step-by-step explanation:
I believe you can use cosine 60° (which is 0.5) and set it equal to x/400
.5 = <u> x </u>
400
x = 200
255-136=119
start at 255 then go down or left 136 times and you'll get 119
Answer:
0.0228
Step-by-step explanation:
Given that:
mean (μ) = 75, Standard deviation (σ) = 3.5
The z score is a score used in statistics to measure by how many standard deviations the raw score is above or below the mean. If the z score is positive, it means that the raw sore is above the mean and if the z score is negative then the raw score is below the mean. The z score is given by:

For x > 76 and a sample (n) = 49:

From the normal distribution table, the probability that the average score of the 49 players exceeded 76 = P(x > 76) = P(z > 2) = 1 - P(z < 2) = 1 - 0.9772 = 0.0228
