Assuming that the two events are independent (i.e. the fact of scoring the first time does not influence the probability of scoreing the second time), the probability of scoring the first time is equal to the probability of scoring the second time.and the joint probabililty is the product of thw two probabilities.


Probability of scoring the first time = 0.30


Probability of scoring the second time = 0.30


Joint probability = 0.30 * 0.30 = 0.09


Then, the answer is 0.09.

Your time spent playing pool and ice skating must not exceed 20 hours a week. Your weekly allowance is $80. You pay $3 an hour p
Anton [14]

Answer:

The graph in the attached figure

Two possible solutions are the point (10,10) and the point (4,8)

see the explanation

Step-by-step explanation:

Let

x ----> the time in hours spent playing pool in a week

y ----> the time in hours spent for ice skating in a week

we know that

x+y \leq 20 ----> inequality A

3x+5y \leq 80 -----> inequality B

using a graphing tool

The solution is the shaded area

see the attached figure

Remember that the time can not be a negative number

If a ordered pair is a solution of the system of inequalities, then the ordered par must lie on the shaded area of the solution

Looking at the graph

Two possible solutions are

(10,10) ----> this point lie on the shaded area of solution

That means -----> The time in hours spent playing pool in a week is 10 and the time in hours spent for ice skating in a week is 10

(4,8) ----> this point lie on the shaded area of solution

That means -----> The time in hours spent playing pool in a week is 4 and the time in hours spent for ice skating in a week is 8

Answer:

17.5 page in 25 minutes

Step-by-step explanation:

We can use ratios to solve

7 pages       x pages

-------------  = ----------------

10 minutes    25 minutes

7 * 25  = 10 x

175 = 10x

Divide by 10

175/10 = 10x/10

17.5 =x

17.5 page in 25 minutes

. The daily sales at a convenience store produce a distribution that is approximately normal with a mean of 1220 and a standard
rewona [7]

Answer:

0.78015

Step-by-step explanation:

Given that :

Mean, μ = 1220

Standard deviation, σ = 110

Probability that sales is less Than 1305 on a given day

P(x < 1305) :

Obtain the standardized score Z

Z = (x - μ) / σ

Z = (1305 - 1220) / 110

Z = 85 / 110

Z = 0.7727272 = 0.7727

P(Z < 0.7727) = 0.78015 (Z probability calculator)
