4/12 in simplest form would be 1/3 because 4 goes into 4, one time and 4 goes into 12, 3 times.
Answer:
Answer Cone Z and Cylinder Y.
Step-by-step explanation:
The relationship between the volume of the cone and the volume of the cylinder with the same height and same base is the volume of the cone is 1/3 of the volume of the cylinder.
The formula for the volume of the cone is :
V = 1/3π
h
The formula for the volume of the cylinder is :
V = π
h
Let be the height of the cylinder Y. Therefore the height of the cone Z is 3h, when we put it into the formula we get :
V = 1/3π
(3h) = π
h
Therefore Cone Z and Cylinder Y have same volume.

Step-by-step explanation:
12 out of 15 = 80%
80% of 435 = 348
Answer:
The parameter is the population proportion of fans who listened to her new single and has an estimated value of 90%.
Step-by-step explanation:
The parameter is a value that corresponds to a population, while an a value that corresponds to a sample is know as statistic.
She takes a sample to estimate, with a point estimate and probably with a confidence interval around this point estimate, the true proportion of fans who listened to her new single.
This is the paramater: the population proportion of fans who listened to her new single.
Its value comes from an estimation based on the sample proportion (point estimate).
The sample proportion is 90%, so we can estimate, as there is no bias, that the population proportion is also 90%.
