A study of king penguins looked for a relationship between how deep the penguins dive to seek food and how long they stay underw

ater. For all but the shallowest dives, there is a linear relationship that is different for different penguins. The study report gives a scatterplot for one penguin titled, "The relation of dive duration (DD) to depth (D)." Duration DD is measured in minutes, and depth D is in meters. The report then says, "The regression equation for this bird is DD=2.69+0.0138D. (a) What is the slope of the regression line? (Enter your answer rounded to four decimal places.)

Answer:

b = 0.0138

Step-by-step explanation:

Given

Regression Equation:

DD=2.69+0.0138D

Required

Determine the slope of the regression line

The equation of regression is of the form

Y =  a + bX

Where b represents the slope;

Compare Y =  a + bX to the given equation

DD=2.69+0.0138D

We have that:

Y = DD

a = 2.69

b = 0.0138

X = D

Hence; the slope is:

b = 0.0138

Find(4) when f(x)=4x^2-3x+3
zimovet [89]
Assuming x = 4, replace each x in the equation with 4:

4(4)^{2} - 3(4) + 3

Solve each term in parentheses:

4(4)^{2}
4^{2} = 16
4 \times 16 = 64

-3(4)
-3 \times 4 = -12

Your equation should now look like this:

64 - 12 + 3 = 55

f(4) will equal 55.
