On a sheet of paper complete the following problem: Suppose a study shows that adults aged 65 and over spend a mean of 1.5 hours per day on social media with a standard deviation of 0.75 hours. Assume the variable is normally distributed. If an adult is selected at random, what is the probability that they spend more than 1 hour per day on social media? Write your answer as a percent rounded to the nearest tenth of a percent.

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
