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

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

It seems logical that restaurant chains with more units (restaurants) would have greater sales. Ca 5 n we predict sales by measuring a restaurant chain's number of units? Presented below are data from nine large restaurant chains. Use the accompanying scatterplot, correlation matrix and simple linear regression output to answer the question that follows the output.

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!

If y = 5x + 9 were changed to y = 5x + 6, how would the graph of the new function compare with the first one?

It would be shifted downward

The inital value would be different. in 5x+9 it would cross the yaxis at 9 and the other at 6

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.

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.

rate of change = (4683 - 14000) / (1998 - 1987) = -847

Thus, the answer is letter B.

MIDDLE SCHOOL

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?

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

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

What are the coordinates of the centroid of a triangle with vertices J(-4,2) K(2,4) and L(0,-2)

Answer:

The correct answer is (-2/3, 4/3).

It would go by (-4,2) then (0,-2) next would be (2,4)

parenthaseese

exponents

muliplication or division

addition r subtraction

so first is multiplication since non partnehatases and exonents

3 times 6=18

now we have

3-18+2

add

3-18=-15

now we have

-15+2=-13

answer is -17 because of order of operations (PEMDAS)

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.

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
