The claim is that for the population of adult males, the mean platelet count is μ>217. The sample size is n=50 and the test

Deffense [45]

Step-by-step explanation:

First, find the degrees of freedom:

df = n − 1

df = 49

To find the p-value manually, use a t-score table. Find the row corresponding to 49 degrees of freedom. Then find the α column that corresponds to a t-score of 1.421. You'll find it's between α = 0.10 (t = 1.299) and α = 0.05 (t = 1.677). Interpolating, we get an approximate p-value of 0.084. For a more accurate answer, you'll need to use a calculator.

Find a cofunction with the same value as the given expression. csc 52°

sweet-ann [11.9K]

To find a cofunction with the same value as the expression csc 52*, you would use the formula like this. csc (x) = sec (90-x). So if you use csc(52) that equals sec(90-52). This in turn, equals sec(38). So the answer is B.

Answer:

16.9 units

Step-by-step explanation:

Sometimes the easiest way to work these problems is to get a little help from technology. The GeoGebra program/app can tell you the length of a "polyline", but it takes an extra segment to complete the perimeter. It shows the perimeter to be ...

14.87 + 2 = 16.87 ≈ 16.9 . . . units

_____

The distance formula can be used to find the lengths of individual segments. It tells you ...

d = √((Δx)² +(Δy)²)

where Δx and Δy are the differences between x- and y-coordinates of the segment end points.

If the segments are labeled A, B, C, D, E in order, the distances are ...

AB = √(5²+1²) = √26 ≈ 5.099

BC = √(1²+3²) = √10 ≈ 3.162

CD = Δx = 3

DE = √(3²+2²) = √13 ≈ 3.606

EA = Δy = 2

Then the perimeter is ...

P = AB +BC +CD +DE +EA = 5.099 +3.162 +3 +3.606 +2 = 16.867

P ≈ 16.9
