In the iris data, we wish to build a simple linear regression model to predict Sepal. Length based on Petal. Length. Calculate the least squares regression line to predict Sepal. Length based on Petal. Length. Interpret the slope of the line in the context of the problem. Remember that both variables are measured in centimeters.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

5/12, or 5: 12

step-by-step explanation:

80 the answer is 80

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt
