Maria runs a channel where she uploads and shares videos that she makes. She noticed an exponential relationship between how long her videos have been posted and the number of times each video has been viewed. Maria took the natural logarithm for the numbers of views only, and she noticed a linear relationship between the how long her videos have been posted and the transformed numbers of views.
Here's the least-squares regression equation for the transformed data, where "time" represents days since posting, and "views" is the number of views.
ln(views)

=0.72(time)+2.65
According to this model, what is the predicted number of views on a video that's been posted for 5 days?

4.6875 pounds

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
