The answer is C
First multiple 4 into bracket then put +1 in both side so it will be y = 4x-11
Answer:
15.40/3.5=$4.40 dollars a pound
7.65/1.8=$4.25 dollars a pound
Step-by-step explanation:
divide to get the unit price
so 7.65/1.8=$4.25 dollars a pound is the cheaper unit as well.
Volume formula of a sphere:
r³
given:
r = 3
V =
(3)³
V =
× 27
V = 36
units³ (in terms of
)
V = 113.097 units³ ≈ 113.1 units³
The best estimate for this correlation would be B) 0.9.
We can see that the number is constantly going up, which would throw out the D answer.
We can also see that for every time the x goes up 1, the y goes up a little less than one. We can see that in the ordered pairs that exist on the graph such as (3, 2), (8, 6) and (2.1, 1.9).
Since the y values are just lower than the x, the correlation would be just under one. Therefore, 0.9 is an accurate estimation.
