Answer:
The radius of the cone is 3 units
Step-by-step explanation:
An oblique cone is a kind of slanted cone. It is a figure such that the tip of the cone is not directly over the center of the circular base of the cone.
While the method for calculating the area of an oblique and a right-circular cone is different, the method for calculating the volume is the same
Mathematically, the volume of an oblique cone = 1/3 * pi * r^2 * h
in this question, we have the height and the volume but we want to calculate the radius
substituting the value for the volume, the height and radius( radius is half diameter = 2x/2 = x) we have
18 pi = 1/3 * pi * x^2 * 2x
divide through by pi
18 = 1/3 * 2x * x^2
54 = 2x^3
divide both sides by 2
x^3 = 54/2
x^3 = 27
x = cube root of 27
x = 3 units
This is the length of the radius

Answer:

Step-by-step explanation:
Given :In a recent questionnaire about food, a random sample of 970 adults were asked about whether they prefer eating fruits or vegetables, and 458 reported that they preferred eating vegetables.
To Find :What value of z should be used to calculate a confidence interval with a 95 % confidence level?
Solution:
Confidence level = 95 % i.e.0.95
So, significance level = 5% i.e. 0.05
So, the value of z corresponding to significance level 0.05 should be used to calculate a confidence interval with a 95 % confidence level
So, 
Hence z should be 1.645 to calculate a confidence interval with a 95 % confidence level.
I think you meant it to be not repeating 3 times so
You do 192/3 is 60*3= 180 leaving you with 12 which is 4*3. So 64 is A
Then it’s 300/5 which is 60
455/7. So first see, if I multiply 7 by 60 is it over or under. If it’s over then B is the least and if it is less then C is the least. So 7 *60 is 420
C Being greater, b costs least per night
