Answer:
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.
to increase each dimension by equal lengths so that its area triples is 12 feet.
The given dimensions are 18 feet by 15 feet.
We need to find how much should each dimension increase.
Shaquana wants to increase each dimension by equal lengths so that its area triples.
Let the increased length be x.
So, length =18+x feet and width=15+x feet.
As we know, the area of a deck=Length×Width
The original area of a deck=18×15=270 square feet.
Now, the new area of a deck=(18+x )×(15+x)=3×270
⇒270+15x+18x+x²=810 square feet
⇒x²+33x-540=0
Here, a=1, b=33 and c=-540 in .
⇒
⇒
⇒x=-45 or x=12
Length can not be a negative integer.
Therefore, to increase each dimension by equal lengths so that its area triples is 12 feet.
