THE GREATEST PRODUCT
Alex17521 [72]

Answer:

<em>7*6543=45801</em>

Step-by-step explanation:

We have the digits 34567 and must arrange them into a product with the largest possible value.

It's clear that we must place the largest digits to the left, so they represent larger numbers to multiply.

Let's try with:

7654*3=22962

765*43=32895

76*543=41268

7*6543=45801

This last combination definitely produces the largest product

Answer: 7*6543=45801

While on a road trip, Steve drove 300 miles in 5 hours. After stopping for gas, he drove an additional 120 miles in 2 hours. Doe
lawyer [7]

Answer:

B.   Yes, this is direct variation. Time is the independent variable, and miles driven is the dependent variable.

Step-by-step explanation:

In a direct variation, when the independent variable increase the dependent variable also increases. In this case, the independent variable is the time (time is always independent) and the miles driven by Steve is the dependent variable. This means, the miles driven increase as time pass.

Answer:  3/4,  because the probability of renting a comedy is 1/4

================================================================

Explanation:

We have 36+26+30+28 = 120 students. 30 of which rented a comedy.

The probability of renting a comedy is 30/120 = (30*1)/(30*4) = 1/4

The probability of not renting a comedy is 1 - (1/4) = 4/4 - 1/4 = (4-1)/4 = 3/4.

Or you could say that 1/4 = 0.25, so 1-0.25 = 0.75 which converts to the fraction 3/4.

If you had 4 people and 1 of them rents a comedy, then the other 3 hasn't rented a comedy.
