ikadub [295]

Answer:

The probability that in a one-game playoff, her score is more than 227 is 0.4404.

Step-by-step explanation:

We are given that Susan has been on a bowling team for 14 years. After examining all of her scores over that period of time, she finds that they follow a normal distribution. Her average score is 225, with a standard deviation of 13.

<em>Let, X = scores over that period of time</em>

X ~ N(\mu = 225, \sigma = 13^{2})

The z score probability distribution is given by;

          Z = \frac{X-\mu}{\sigma} ~ N(0,1)

where, \mu = average score

            \sigma = standard deviation

So, probability that in a one-game playoff, her score is more than 227 is given by = P(X > 227)

    P(X > 227) = P( \frac{X-\mu}{\sigma} < \frac{227-225}{13} ) = P(Z > 0.15) = 1 - P(Z \leq 0.15)

                                                      = 1 - 0.55962 = 0.4404

Therefore, probability that in a one-game playoff, her score is more than 227 is 0.4404.

Two rectangular prisms have a combined volume of 432 cubic feet. Prism A has half the volume of Prism B.
dexar [7]

Answer:

a. 144 cubic foot

b. 12 ft

c. 18 ft

Step-by-step explanation:

Let the volume of prism A be V_a

and that of prism b be V_b

ATQ,   V_a  +  V_b= 432

also V_a= 0.5 V_b

⇒1.5 V_b= 432

= V_b= 432/1.5= 288 cubic feet

therefore V_a= 144  cubic feet

volume of prism= area of base×height = V_a

24×h = 144

⇒h= 12 ft

A_b= 2/3×24

⇒base area of prism B= 16 sq.ft

now 16×h_b= 288⇒h_b= 288/16= 18 ft
