A wildlife biologist is interested in the relationship between the number of chirps per minute for crickets (y) and temperature. Based on the collected data, the least-squares regression line is y x ˆ = + 10.53 3.41 , where x is the number of degrees Fahrenheit by which the temperature exceeds 50° . Give a sentence that describes the meaning of the slope of the least-squares regression line.

the number of cephalopods in her seashells collection is 26.

Step-by-step explanation:

Maria has a collection of 64 seashells consisting of three types bivalves,gastropods,and cephalopods. If 1/4 of her collection are bivalves, it means that the number of bivalves that she has is

1/4 × 64 = 14

If 3/8 of her collection are gastropods, it means that the number of gastropods in her collection is

3/8 × 64 = 24

Therefore, the number of cephalopods in her seashells collection is

64 - (14 + 24) = 26
