Answer:

2 point questions would be 42.5

5 point questions would be 17

Step-by-step explanation:

40 + 2x = 125

Subtract 40 on both sides

40-40 + 2x = 125-40

You'll end up with:

2x= 85

So you'll have to do the opposite of multiplication for both sides, which is division.

2x/2 = 85/2  -------------> x= 42.5

----------------------------------------------------

40 + 5y = 125

Subtract 40 on both sides

40-40 + 5y = 125

You'll end up with

5x = 85

So you'll have to do the opposite of multiplication for both sides, which is division.

5x/5 = 85/5 ----------------> x= 17

I hope this helped !! :)

HEY THERE !!

Factorization of the trinomial
3x^3 +6x^2 -24x
will be :-

taking common 3x

=>3x(x^2+2x-12)......1️⃣

now the factorization of (x^2+2x-12) will be
(x-2)(x+4).......2️⃣

so your answer from 1️⃣and 2️⃣ is (A) 3x(x-2)(x+4).

Hope it helped you.

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.

Write 7/10 as a sum of fractions three diffrent ways​
Elanso [62]

Answer:

3/10 + 4/10

1/2 + 1/5

1/10 + 3/5

Step-by-step explanation:

3/10 + 4/10 = 7/10 (add numerator and keep denominator)

1/2 + 1/5 = 5/10 + 2/10 = 7/10 (use equivalent fractions)

1/10 + 3/5 = 1/10 + 6/10 = 7/10

I hope this helped and please mark me as brainliest!
