Jason is a very good bowler and has proven over the

Nonamiya [84]

Answer:

The probability that Jason will get exactly 7 strikes out of 10 attempts is 0.117.

Step-by-step explanation:

We are given that Jason is a very good bowler and has proven over the course of a season of league play that he gets a STRIKE 50% of the time.

Also, Jason has been given 10 attempts.

The above situation can be represented through binomial distribution;

$P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......$

where, n = number trials (samples) taken = 10 attempts

r = number of success = 7 strikes

p = probability of success which in our question is % of the time

he gets a strike, i.e; p = 50%

Let X = Number of strikes Jason get

So, X ~ Binom(n = 10, p = 0.50)

Now, probability that Jason will get exactly 7 strikes out of 10 attempts is given by = P(X = 7)

P(X = 7) = $\binom{10}{7} \times 0.50^{7} \times (1-0.50)^{10-7}$

= $120 \times 0.50^{7} \times 0.50^{3}$

= $120 \times 0.50^{10}$

= 0.117

Therefore, the probability that Jason will get exactly 7 strikes out of 10 attempts is 0.117.

the revenue for the school play is given by: r=-50t^2 + 300t, where “t” is ticket price in dollars. The cost to produce the play

artcher [175]

ANSWER

EXPLANATION

The revenue function is

$r = - 50 {t}^{2} + 300t$

The cost function is,

C=600-50t

In order to break even, revenue must be equal to cost.

$600 - 50t= -50 {t}^{2} + 300t$

Group every term on the LHS.

$50 {t}^{2} - 300t - 50t + 600 = 0$

$50{t}^{2} - 350t + 600 = 0$

Divide through by 50.

${t}^{2} - 7t + 12= 0$

Factor to obtain,

$(t - 3)(t - 4) = 0$

$t = 3 \: or \: t = 4$
