Choose whether the probability is mutually exclusive or not

Semmy [17]

9514 1404 393

Answer:

mutually exclusive

Step-by-step explanation:

The formula of interest is ...

P(A or B) = P(A) + P(B) - P(A and B)

Filling in the given values, we have ...

9/10 = 2/5 + 1/2 - P(A and B)

Solving for P(A and B), we get ...

P(A and B) = 2/5 +1/2 -9/10 = 4/10 +5/10 -9/10

P(A and B) = 0

Events are mutually exclusive when they can never happen at the same time. That is, P(A and B) = 0.

The events A and B are mutually exclusive.

Jodi built a rectangular sandbox for her daughter. The sandboxmeasures6 feet by 5feet by 1.2 feet. Jodi purchases 20cubic feet o

Mamont248 [21]

For this case, the first thing to do is to model the rectangular sandbox as a rectangular prism.

The volume of the prism is given by:

$V = w * l * h$

Where,

w: width
l: length
h: height

Therefore, replacing values we have:

$V = 6 * 5 * 1.2\\V = 36 ft ^ 3$

We observed that:

$36 ft ^ 3> 20 ft ^ 3$

Therefore, the sandbox is not completely filled.

Answer:

the sandbox will hold $36 ft ^ 3$ of sand

Jodi purchase is not enough sand to fill the sandbox to the top.

$36 ft ^ 3> 20 ft ^ 3$

Write in lowest terms: 7x2 - 13x - 2 27x2 - 6x - 1

Ksju [112]

So... get the like-terms and add/subtract $7x^2-13x-2+27x^2-6x-1
\\ \quad \\
\textit{add/subtract the like-terms}
\\ \quad \\
\boxed{7x^2+27x^2}\quad \boxed{-13x-6x}\quad \boxed{-1-2}$

see what that gives you
