OLEGan [10]

Answer:

See the calculation below

Step-by-step explanation:

16 + 13 + 20 = 49

blue =  \frac{16}{49}  \times 4900 \\  = 1600

green =  \frac{13}{49}  \times 4900 \\  = 1300

black =  \frac{20}{49}  \times 4900 \\  = 2000

Imagine that a researcher develops a new cancer drug that shrinks tumors, which she measures using an MRI. The researcher needs
Bas_tet [7]

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!!!

Find the surface area of the regular pyramid shown to the nearest whole number. The figure is not drawn to scale.
Pavlova-9 [17]
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.

\bf \stackrel{\textit{area of the hexagon}}{\left[\cfrac{1}{2}(6\sqrt{3})(72)  \right]}~~~~+~~~~\stackrel{\textit{area of the 6 triangles}}{6\left[\cfrac{1}{2}(12)(11)  \right]}
