The level of calcium in the blood of healthy young adults follows a Normal distribution with a mean of LaTeX: \mu = 10μ = 10 milligrams per deciliter and a standard deviation of LaTeX: \sigma = 0.4.σ = 0.4. A clinic measures the blood calcium of 100 healthy pregnant young women at their first visit for prenatal care. The mean of these 100 measurements is LaTeX: \bar x= 9.8x ¯ = 9.8. Is this evidence that the mean calcium level in the population of healthy pregnant young women is less than 10?

answer: -8.2562234e+13

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
