Find the probability that your friend is at least 20 minutes late

Mathematics

If the graph has 1/3 length…

At least 20 minutes late: this would mean 20 minutes late or more.

20 or more minutes goes from 20 to 30. So that is a difference of 30 – 20 = 10. The distance of your rectangle is 10.

Length * width = (1/30) * 10 = 1/3 or 0.3333. The probability the friend is at least 20 minutes late is 0.3333.

Anon25 [30]

Answer:

4x^{2}

Step-by-step explanation:

Given:

Amy works for a marketing agency and is designing a label for a company's newest product.

The label needs to be a rectangle where the length is 4 times the width.

x represents the width.

Question asked:

Which expression represents the area of the label ?

Solution:

Width of the label = x (given)

Then, length of the label will be = <u>4 times the width</u> = 4x

As label needs to be a rectangular shape and as we know:-

Area\ of\ rectangle=Length\times width

                              =4x\times x\\=4x^{2}

Therefore, 4x^{2} represents the area of the label.

Can someone help me with this question? <br> (2,5) and (10,3) What is the slope and the y-intercept
Paha777 [63]

Answer:

slope is -1/4

y intercept is 11/2

Step-by-step explanation:

the slope is (3-5)/(10-2) = -2/8 = -1/4 (using the slope formula)

the y intercept we can set up an equation, y= mx + b

we already know m, which is -1/4 (the slope), and to find b, we could just plug in one of the points to get

5 = (-1/4)*2+b

solve the equation

b = 11/2
