The first 15 seconds of a dolphin swimming in the ocean is modeled by a polynomial function where t is the time in seconds and h(t) is equal to the dolphins height above sea level in feet. In
factored form, the dolphin's path can be modeled by the function
k(t) =-.0001(t+1)(t-2)(t-4) (t-10)*2(t-14)(t- 15)
What key feature(s) can be easily identified from the factored form? Explain each
key feature is related to the dolphin. Use specific values in your explanation.

The coach should start recruiting players with weight 269.55 pounds or more.                                                    

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 225 pounds

Standard Deviation, σ = 43 pounds

We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.

Formula:

We have to find the value of x such that the probability is 0.15

Calculation the value from standard normal z table, we have,  

Thus, the coach should start recruiting players with weight 269.55 pounds or more.
