Answer:
Complementary
Step-by-step explanation:
Complementary Angles add up to 90°
Supplementary Angles add up to 180°
60 + 30 = 90
Answer:
See the calculation below

Answer:
Assuming that the null hypothesis is true and that the new cancer drug shrinks tumors by the same amount as the gold-standard drug, the probability that the test will lead the researcher to this decision = 95%
Step-by-step explanation:
The nulll hypothesis is correct and we are not rejecting it, which means we are making the correct decision.
P(not rejecting the null | null hypothesis is true)
= 1 - P(rejecting null hypothesis | null hypothesis is true)
= 1 - P(type I error)
P(type I error) = significance level of the test = 0.05
P(not rejecting the null | null hypothesis is true)
= 1 - 0.05
= 0.95
= 95%
Hope this Helps!!!
If you look at the pyramid, the pyramid is really just a hexagon with 6 triangles stacked up to each other at the edges, with the hexagon at the bottom.
now, the perpendicular distance from the center of the hexagon to a side, namely the
apothem, is 6√3, and each side is 12 units long, since there are 6 of them that'd be 72 for all, namely the
perimeter.
each of the triangular faces have a base of 12 and an altitude or height of 11, recall that area of a triangle is (1/2)bh, and area of a regular polygon is (1/2)(apothem)(perimeter).
so if we just get the area of the hexagon at the bottom, and the triangles, sum them up, that's the surface area of the pyramid.
