d = total distance of the trip. We know that 345 miles is only 3/5 of the trip. Due to the fact that we know this, we can do some simple math to find the total distance. 345/3 = 115

115 * 5 = 575

This means we are looking for the equation which gives us d = 575.

Lets solve each problem:

A) 3/5 / d = 345. This would give us d = .0017. Which is way too small to be the total distance.

B) 3/5 * d = 345. This would give us d = 575. Seems like our answer, but lets keep trying the other ones.

C) 345 * d = 3/5. d = .0017, this is not right.

D) 345 / d = 5/3. This is d = 207, which is also wrong.

So our answer should be B. \frac{3}{5} *d=345

I hope this helps! :)

The amount of time it takes Renee to go grocery shopping is continuous and uniformly distributed between 18.5 minutes and 40.5 m
balandron [24]

Answer:

47.73% probability that it takes Renee at most 29 minutes to go grocery shopping

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

P(X \leq x) = \frac{x - a}{b-a}

Uniformly distributed between 18.5 minutes and 40.5 minutes.

This means that a = 18.5, b = 40.5

What is the probability that it takes Renee at most 29 minutes to go grocery shopping

P(X \leq 29) = \frac{29 - 18.5}{40.5 - 18.5} = 0.4773

47.73% probability that it takes Renee at most 29 minutes to go grocery shopping

Answer:B. 2x^2 + 4x - 1 - 9/4x + 1

Step-by-step explanation:

f(x) = 8x^3 + 18x^2 − 10

g(x) = 4x + 1

We want to determine f(x)/g(x). We would apply the long division method. The steps are shown in the attached photo.

The correct answer is

2x^2 + 4x - 1 - 9/4x + 1

B/ 21 Marks
Serggg [28]

Answer:

y = 3x + 1.

Step-by-step explanation:

The slope is y2-y1/x2-x1

= 10/1/ 3-0

= 9/3

= 3.

Using the point-slope form for a straight line:

y-y1 = m(x-x1)     (m = slope)

y - 10 = 3(x - 3)

y - 10 = 3x - 9

y = 3x - 9 + 10

y = 3x + 1  is the required equation.
