I need help with these two
djyliett [7]

Answer:

Part 1) Slope-intercept form

Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee

Step-by-step explanation:

Part 1) we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

y=2.50+2.20x

This is a linear equation in slope intercept form

where

m=2.20

b=2.50

Part 2) we have that

x -----> represent the number of miles

y ----> represent the total charge in dollars

The slope is

m=\$2.20\ per\ mile ---> unit rate

The y-intercept is

b=\$2.50 ----> initial value or flat fee

therefore

The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee

Q. The probability that a student passes a statistics test is 2/3 and the
kenny6666 [7]

Answer:

4/9 or 44.44%

Step-by-step explanation:

We have the following probabilities:

Probability of winning the statistical test = P (s) = 2/3

Probability of winning the mathematics and statistics test = P (s n m) = 14/45

Probability of winning at least one test = P (s u m) = 4/5

We have that, the probability of winning the mathematics test P (m) can be found in the following way:

P (s n m) = P (s) + P (m) - P (s u m)

replacing we have:

14/45 = 2/3 + P (m) - 4/5

P (m) = 14/45 - 2/3 + 4/5

p (m) = 4/9 = 0.444

Which is the same as there is a 44.44% probability that I will win the math test
