The life expectancies (in years) for men and women in the U. S. can be given using models in slope-intercept form. Women: L = m t + b Men: L = m t + b where t is the number of years since 1980. Suppose that in 1980, women's life expectancy was 77.2 and was increasing by 0.09 years of life expectancy per year of time. (In other words, each year that passed saw women's life expectancy go up an additional 0.09 years.)

answer: 1 and 3

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
