Answer:
Step-by-step explanation:
Let p be the population proportion.
Given : According to a recent study of 7335 young people in the US, 30% had been arrested for a crime other than a traffic violation by the age of 23. i.e.p= 0.30
The margin of error for the population proportion estimate, p : E= 0.01 .
Then, the range of plausible values for the parameter will be :-
Hence, the required answer =
Answer:
∴ opposite side = √108
Step-by-step explanation:
Here hypotenuse = 12 ft
It is a right angled triangle.
here triangle ABC in which ∠ C = 60°
∠B = 90°
so ∠A = 180° -( 90 +60)
= 180 - 150
= 30°
cos 60° = adjacent side ÷ hypotenuse
= x ÷ 12
=
12 = 2 x
∴ x = 6
adjacent side = 6
hypotenuse ² = adjacent side² + opposite side²
12² = 6² + opposite side²
144 - 36 = opposite side ²
108 = opposite side²
∴ opposite side = √108
