the ratio of students with bikes to students with scooters in the school is 85:51. What is the greatest common factor that you could use to simplify this ratio

Answers

Answer:GCF=17

To find the greatest common factor, or GCF, of the numbers, we first need to list the prime factors of both 85 and 51

52=3*17

85=5*17

17 is the sole common factor that these two numbers have in common, therefore 17 is the GCF.

To simplify the ratio, simply divide both numbers by 17.

85:51 becomes 5:3
The greatest common factor is 17

Answers

Answer:

Step-by-step explanation:

Hello!

A regression model was estimated in order to test if the number of units of a restaurant chain affecta the sales of said restaurant chains.

The estimated model is:

Y= a + bX

Where

Y: is the sales of a restaurant chain

X: number of units of a restaurant chain

Looking at the computed data, the estimated coefficients are:

a= 4.633131413

b= 0.439724072

The correct regression equation to predict Sales based on Units, according to this analysis, is..

Y= 4.63 + 0.44X

I hope it helps!

In 1987 a recording artist sold 14,000 albums. In 1998 that same artist sold 4,683 albums. Find the rate of change in record sales from 1987 to 1998. A. 1/847 years per album. B. –847 albums per year. C. 847 albums per year. D. –847 years per album.

Answers

The rate of change in the record sales is the difference of the number of albums sold over the time elapsed from 1998 to 1987. That is,
                          rate of change = (4683 - 14000) / (1998 - 1987) = -847
Thus, the answer is letter B.

Marita orders 12 yards of material to make banners. If she needs 1 foot of fabric for each banner, how many banners can she make?

Answers

Well 3 feet=1 yard
so the conversion factor is 3ft/1yd

so 12 yards converted to feet is
12yd times 3ft/1yd
the yd will cancel and you will be left with 36 feet

each banner is 1 foot so 36/1=36
she can make 36 banners

Elly buys 75 shares of stock in a mutual fund for a total investment of $450. She sells 50 shares of her stock for total proceeds of $400. Determine if Elly made a profit or loss, and how much per share.

Answers

Answer:

She made a profit of $ 2 on each share of stock

Step-by-step explanation:

Elly buys 75 shares of stock in a mutual fund for a total investment of $450.

cost of 1 share of stock= $ 450/75

                                   =  $ 6

She sells 50 shares of her stock for total proceeds of $400.

selling price of 1 share of stock=$ 400/50

                                                 = $ 8

Hence, She made a profit of $ 2 on each share of stock   ($8-$6=$2)

She made $2 per share
