A randomized study compared the effectiveness of two different flea collars for dogs. The dogs in the treatment group using flea collar A had a mean of 2.8 fleas. The dogs in the treatment group using flea collar be had a mean of 3.3 fleas. To determine if the results are significant data or rerandomized in the differences of the means are shown in the dot plot. What is the best conclusion to make based on the data?

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48

step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one

using pemdas, (order of operations) you'll see the answer is 24.
