Answer:
a) Mean = 0.30, SD = 0.017
Step-by-step explanation:
The mean and sampling distribution of the sample proportion can be found using the equations
Mean= p
where
- n is the sample size (750)
- p is the sample proportion of all Division I athletes think that these drugs are a problem (0.30 or 30%)
Using these information:
Mean = 0.30
≈ 0.017
Incomplete question. However, here is a similar question attached.
Solve 3x^2 + 17x - 6 = 0.
Based on the work shown to the left, which of these values are possible solutions of the equation? Check all of the boxes that apply
A X=-6
B X=6
C X=-1/3
D X=1/3
E X=0
Answer:
A and D
Step-by-step explanation:
Note that such question requires using completing the square method of solving equations. By using the values X= -6 and X= 1/3 we arrive at a solution.
the length of the hypotenuse is 25 units and the length of the other leg is 15 units
To find the length of one leg of a right triangle we apply Pythagorean theorem
(one leg)^2 = hypotenuse ^2 - other leg ^2
Let x be the length of one log
hypotenuse = 25
other log = 15
Take square root on both sides
x = 20
The length of one leg = 20 units
