Answer:

See below.

Step-by-step explanation:

1.)

$24=-3+3n\\27=3n\\9=n$

2.)

$11+4x=x-10\\11+3x=-10\\3x=-21\\x=-7$

3.)

$-216=1+7(1+8m)\\-216=1+7+56m\\-216=8+56m\\-224=56m\\-4=m$

4.)

$3p-3(2-2p)=34+4p\\3p-6+6p=34+4p\\9p-6=34+4p\\5p=40\\p=8$

-5(5-3v)=-115<br> Helpp me please

prisoha [69]

we start by opening the brackets so it will be -25 plus 15 v is equals to 115. negative times a negative is a positive so -5 times -3 we we have gotten positive 15v there I hope you understood so our new equation is -25 + 15v is equals to 115 collect the like terms 15v is equals to 115 + 25 15 v is equals to 140 divide both sides by 15 so v is equals to 9 and 1/3

The probability that a toy Raymond picks out of a box is both plush and a dinosaur is 30%. The probability that a toy Raymond pi

GalinKa [24]

Answer:

0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Dinosaur

Event B: Plush.

The probability that a toy Raymond picks out of a box is a dinosaur is 75%.

This means that $P(A) = 0.75$

The probability that a toy Raymond picks out of a box is both plush and a dinosaur is 30%.

This means that $P(A \cap B) = 0.3$

What is the probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.3}{0.75} = 0.4$

0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.

Use greatest common factor and the distributive property to write equivalent expressions in factored form for the following expr

Nitella [24]

Answer:

a. 4(d+3e)

b. 6(3x+5y)

c. 7(3a+4y)

d. 8(3f+7g)

Step-by-step explanation:

In each case we find the greatest common factor of the numbers. That is the greatest number that goes into both the numbers. Then we factor it out in front and inside parentheses we divide each original term by the greatest common factor:

a. 4d+12e, GCF: 4

$\displaystyle4\left(\frac{4d}{4}+\frac{12e}{4}\right)=4(d+3e)$
