7) 1/3

The keyword 'and' here implies that we need to multiply. Both events are independent of each other, so we can just multiply the probability of each occurring together.

Probability of rolling a number less than 5: 4/6

Probability of spinning an even number: 3/6

4/6 x 3/6 = 1/3

8) It is likely that a 7th grade student will pick pizza as his/her favorite food.

5/8 is approximately 62.5%. The probability of this event occurring is fairly high, so we would say that this event is likely to happen.

Hope this helps! :)

Annabelle read 10 books in 2 months. What was her rate of reading, in books per month?

goblinko [34]

Answer:

5 books per month

Step-by-step explanation:

We are trying to find a rate.

To find books per month, we would take the number of books and divide it by the number of months.

This would give us 10 books/2 months.

10/2 simplifies to 5.

Therefore the answer would be 5 books per month.

The number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function T, where x is the number of

Svetradugi [14.3K]

Answer:

Option A:

$R(x)=20x^2+300x+1080$

Explanation:

The revenue, R(x) is the product of the number of teams who entered the tournament, T(x), times the entry fee paid by each team, F(x); then you can write:

$R(x)=T(x)\times F(x)$

Thus you must multiply the two functions (polynomials):

$R(x)=(4x+24)\times (5x+45)$

Use distributive property:

$R(x)=(4x+24)\times (5x+45)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)$

Simplify:

$R(x)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)=20x^2+180x+120x+1080$

Add like terms:

$R(x)=20x^2+180x+120x+1080=20x^2+300x+1080$

NEED ANSWER ASAP pls

Answer:

Let F = Fran's income

Let W = Winston's income

Combined income is 80000 ==> F + W = 80000

One quarter of Winston's income is the same as one-sixth of Fran's income ==>

(1/4)*W = (1/6)*F

Multiply the 2nd equation by 12 to clear the fractions

3*W = 2*F

Solve this equation for F

F = (3/2)*W

Substitute this value for F into the 1st equation

(3/2)*W + W = 80000

(5/2)*W = 80000

W = (2/5)*80000 = 32000

So F = 80000 - 32000 = 48000

So Winston earns 32000 and Fran earns 48000

Check: One quarter of Winston's income is 32000/4 = 8000

One sixth of Fran'e income is 48000/6 = 8000

Step-by-step explanation: Hope this helps

The useful life of an electrical component is exponentially distributed with a mean of 1000 hours a. What is the probability the

julia-pushkina [17]

Answer:

0.865

Step-by-step explanation:

To solve for the probability we would be using the formula:

F(x) = 1 - e^−λx

Therefore, P(x > 2000) = F(x) = 1 - e^−λx

Mean = 1000 hours

λ = 1/mean = 1/1000 hours

x= 2000 hours

F(x) = 1 - e^−(1/1000)2000

F(x) = 1 - e^−2

= 0.8646647168

Therefore, the probability the the circuit will last at least 2000 hours = 0.865
