TEA [102]

Answer: 0.2119

Step-by-step explanation:

We assume that the random variable X is normally​ distributed.

Given : Population mean : \mu=100

Standard deviation : \sigma=20

Z-score : z=\dfrac{x-\mu}{\sigma}

Then, z-score corresponds to 116

z=\dfrac{116-100}{20}=0.8

By using the standard normal distribution table for z , we have

P(x>116)=P(z>0.8)=1-P(z\leq0.8)

=1-0.7881446\approx0.2119

Hence, the required probability = 0.2119

Complete question

<em>18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented </em>

<em>clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a </em>

<em>variable, write an equation, and solve the problem.</em>

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16

Let the cost of green fees per person be y

If Luis and three friends went golfing, this means that 4 people went golfing.  The total cost of green fees for all of them will be $4y

If two of the friends rented clubs for $6 each, total amount spent will be $2(6)

The equation that models the statement will then be expressed as;

4y + 2(6) = 76\\

Solve for y

4y + 2(6) = 76\\4y+12 = 76\\4y = 76 - 12\\4y = 64\\y =\frac{64}{4}\\y = 16

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16.
