A city manager made a scatter plot of number of retail stores in a certain cirty over years. The scatterplot had a trend like wi th an equation of y=11x+12, where y is the total number of retail stores and X is the number of years since 1990. Mark and his family moved to a city in 1997. How many retail stores were their in 1997
1 answer:
Answer: There were 89 retail stores in 1997.
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the number of years since 1990(x).
1997-1990 = 7 years
Now, we simply substitute x=7 (years) in the equation given
y=11x+12
y=11(7)+12
y=77+12
y = 89 retail stores
There were 89 retail stores in 1997.

Step-by-step explanation:
y= kx
or, k= y/x
or, k = 5/4
k = 1.25
y= kx = 1.25 × (-8) = -10

Answer:
8.4 cm^3 to the nearest tenth.
Step-by-step explanation:
The ratio of the volumes of the 2 cones is the ratio of the cubes of their radii.
So:
5^3 / 2^3 = 131 / v
v = 2^3 * 131 / 5^3
= 8 * 131 / 125
= 8.384.
Answer: 36 Explanation: 36 is the smallest number divisible by both 12 and 18. 12x3 and 18x2 = 36
Answer:
57
Step-by-step explanation:
( 27 + 19 + 41 + 51 + 29 + 35 + k ) / 7 = 37
202 + k = 37 x 7
202 + k = 259
k = 259 - 202
k = 57
