Can someone explain to me how Slope Rise over Run works? I just don’t understand it no matter how many times I look into it.

Answer: 4/35

Step-by-step explanation:

Number of red marbles = 4

Number of blue marbles = 5

Number of green marbles = 6

Total number of marbles = 4+5+6 = 15

When a red marble is picked, the probability is 4/15, then to pick a green marble after that, we have 14 marbles left and probability of picking green is 6/14.

Now, probability of choosing a red marble from the bag, not putting it back, and then choosing a green marble will be:

= 4/15 × 6/14

= 24/210

= 4/35

Answer:

A. 3.15

Step-by-step explanation:

E(x) = 3.15.

By displaying the proportion of data points (referred to as "bars") that fall inside a certain range of values, a histogram gives a visual explanation of numerical data. A vertical bar graph and a histogram are comparable.

E(X) = ∑( x ∗ P(x))

Given a probability histogram for a discrete random variable X.

We will drive the P(x) for every value of x.

P(X=1)=0.1

P(X=2)=0.2

P(X=3)=0.3

P(X=4)=0.25

P(X=5)=0.15

Putting these values in a summation equation to find E(x)

E(x) = 1*0.1 +2*0.2 + 3*0.3 + 4*0.25 + 5* 0.15

E(x) = 3.15

Therefore E(x) for the given histogram far random variable x will be 3.15.

Answer:

Step-by-step explanation:

This is because,

According to Triangle Inequality Property:

Measurement of any two sides of a triangle is always greater than the third side.

Here,

10 + 16 = 26 > 21

10 + 16 = 26 > 22

10 + 16 = 26 > 22

But,

10 + 16 = 26 < 27

Hence,

Option D: 27 can't be the measurement of the triangle.

Step-by-step explanation:

We know that she uses one tank of gas every 375mi, so we can just divide.

1125 / 375 = 3

To check our work we can just multiply.

375 x 3 = 1125.

So she uses 3 tanks on the trip. I hope this helps :)

5x² - 5x + 17

Step-by-step explanation:

(3x² + 7) + (2x² - 5x + 10)

Combine the like terms.

3x² + 2x² = 5x²

-5x does not have a like term, so there is no change.

7 + 10 = 17

Combine them, and the final equation is

5x² - 5x + 17.

Answer: 5x² - 5x + 17

Step-by-step explanation:

(3x^2+7)+(2x^2-5x+10)

3x^2 + 2x^2

-5x

7 + 10

5x^2 - 5x + 17

Step-by-step explanation:

a trinomial  is composed by three monomials.

So only A and B can be correct

the degree of a polynomial is the same of the monomial that compose it with the biggest degree

so the answer is B because the monomial with the biggest degree is 3x^4 (its degree is 4)

Answer:

length = 6

width = 3 1/2

Step-by-step explanation:

l = length

w = width

l = 2w-1

w(2w-1) = 21

2w² - 1 - 21 = 0

(2w - 7)(w + 3) = 0

w = 7/2 = 3 1/2

find 'l':  l = 2(7/2) - 1 = 7-1 = 6
