Answer/Step-by-step explanation:
Given:
m<A = 115,
m<B = 78,
m<C = 35,
✔️m<1 = 180 - m<A (angles on a straight line/supplementary angles)
m<1 = 180 - 115 (substitution)
m<1 = 65°
✔️m<2 + m<1 + m<B = 180° (sum of interior angles of a triangle)
m<2 + 65 + 78 = 180
m<2 + 143 = 180
m<2 = 180 - 143 (substitution property of equality)
m<2 = 37°
✔️m<3 = 180° - m<B (supplementary angles)
m<3 = 180 - 78
m<3 = 102°
Answer:
The answer is "
"
Step-by-step explanation:
Given:
When 
confidence level so, the z:
When 98% confidence interval estimate of the population mean is,
2 and 3 are correct. 1 is false because the graph opens downward. If the a value, which is -1 in this case, is less than 0, the graph will open downward. -1 is less than 0 so the graph opens downward
