Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= 5.6 feet
Sample size, n = 27
Alpha, α = 0.10
Sample standard deviation, s = 0 .1 feet
90% Confidence interval:
Putting the values, we get,
Option a) [5.567, 5.633]
Answer:
12 cm³
Step-by-step explanation:
the volume of the sphere = 4/3 πr³
the volume of the cylinder (h=2r)= πr².2r
= 2πr³
the volume ratio of S : C =
4/3 πr³ : 2 πr³
= 4/3 : 2
= 4 : 6
= 2 : 3
so, the volume of the Sphere =
2/3 × 18 = 12 cm³
Answer:
9
Step-by-step explanation:
f(x) = -x^2
f(3) = -3^2
f(3) = 9
