Jackson is building a small rectangular basketball section in his backyard. The length of the section will be 1.25 times the wid
il63 [147K]

Answer:

<u>The dimensions of the basketball section are: length of 17.5 feet and width of 14 feet.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Length of the small rectangular basketball section = 1.25 times the width

2. Part A. Create an equation to represent the area of the basketball section, A, in terms of the width, w.

Let's recall that the formula of the area of a rectangle is:

Area = Length * Width, therefore:

A = 1.25w * w

<u>A = 1.25w²</u>

Part B. Jackson decides to make the area of the basketball section 245 sq feet. What are the dimensions, in feet of the basketball section?

Let's replace the value given in the equation we created in part A, this way:

A = 1.25w²

245 = 1.25w²

w² = 245/1.25

w² = 196

√w² = √196

w = 14 ⇒ 1.25w = 17.5

<u>The dimensions of the basketball section are: length of 17.5 feet and width of 14 feet.</u>

Scores on a college entrance examination are normally distributed with a mean of 500 and a standard deviation of 100. What perce
Alla [95]

Answer:

The percentage is P(350 <  X  650 ) = 86.6\%

Step-by-step explanation:

From the question we are told that

   The population mean is  \mu  =  500

     The standard deviation is  \sigma  =  100

The  percent of people who write this exam obtain scores between 350 and 650    

    P(350 <  X  650 ) =  P(\frac{ 350 -  500}{ 100}

Generally  

               \frac{X -  \mu }{\sigma }  =  Z (The \  standardized \  value \ of  \  X )

   P(350 <  X  650 ) =  P(\frac{ 350 -  500}{ 100}

   P(350 <  X  650 ) =  P(-1.5

   P(350 <  X  650 ) =  P(Z < 1.5) -  P(Z <  -1.5)

From the z-table  P(Z <  -1.5 )  =  0.066807

   and P(Z < 1.5  ) =  0.93319

=>    P(350 <  X  650 ) =  0.93319 -  0.066807

=>  P(350 <  X  650 ) = 0.866

Therefore the percentage is  P(350 <  X  650 ) = 86.6\%
