Answer:
x = ![\frac{13}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D)
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
2x = 13 ( divide both sides by 2 )
x = ![\frac{13}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D)
Answer:
q = 94
p = 18
Step-by-step explanation:
The triangles are congruent so q = 94
Add q + 68 same as 94 + 68 = 162
Subtract 162 from 180 to get p
180 - 162 = 18
Hope this helps!
Answer:
The mean of the sampling distribution of p is 0.75
The standard deviation of the sampling distribution of p is 0.0274
Step-by-step explanation:
According to the given data 75% of the sampled households watch sports on television at least once a month therefore the mean of the sampling distribution of p is 0.75.
In order to calculate the standard deviation of the sampling distribution of p we would have to use the following formula as follows:
Standard deviation = √ [ p ( 1 - p) / n ]
= √[ 0.75 * ( 1 - 0.75) / 250]
= 0.0274
The standard deviation of the sampling distribution of p is 0.0274.
The answer is 4/3 as you can cancel 5 and 10 you get 2 as the numerator and then times 2/3
