Can hair length be used to predict the height of a person? To try to answer this, the following random subset of data were collected from our class’s data: Hair length: 8 12 18 24 1 4 24 2 Height: 68 60 61 67 67 70 68 70 1. Create a scatter plot of the data 2. Find the equation of the regression line 3. Calculate the correlation coefficient. 4. Is there a significant correlation between hair length and height? Use α=.05. 5. Calculate the coefficient of determination. What does this value say about the relationship between hair length and height? 6. What would you expect the height to be of a person with 4 inches of hair? 7. Create a 90% prediction interval for the height of a person with 4 inches of hair.

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
