A fisheries biologist is interested in studying the relationship between width and weight in horseshoe crabs. She collects a random sample of such crabs and cross-classifies them based on these variables as given below. Width (in cm) Weight Tiny 0–5 Small 5–10 Medium 10–15 Large 15–20 Light (<1.8kg) 39 36 29 18 Heavy (>1.8kg) 11 14 21 32 The chi-square statistic for these data equals 21.9. The P-value is

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).

step-by-step explanation:

493 would be the correct answer
