Complete Question :

The surface area of a given cone is 1,885.7143 square inches. What is the slant height?

Answer:

25 inches

Step-by-step explanation:

In the diagram, we are given the following information

Height of the cone = 20 inches

Radius of the cone = 15 inches.

The formula for the slant height of a cone represented by l =

l² = r² + h²

l = √(r² + h²)

l = √(15² + 20²)

l = √(225 + 400)

l = √625

l = 25 inches

Therefore, the slant height of this cone = 25 inches

How do you describe the function of a graph?
Valentin [98]

The graph of a function is the set of all those point which when placed on a graph represents the data in unorganised manner.

In order to describe the function of a graph the first thing that we do is to stabilize a relationship between the co-ordinate axes.

We closely observe and analyse the change of one Axis with the changes of other. After this step we make a set of all the possible points which are describing the function properly within the range and domain of the function. One Axis represents the domain and the other access represents the range.

After this we finally conclude that the function of a graph is set of all those points which represents and shows the data on a diagram in a well organized and understandable manner.

Test the claim that the proportion of people who own cats is significantly different than 90% at the 0.1 significance level.
miss Akunina [59]

Answer:

The right answer is Option B:

H_0: \pi=0.9\\\\H_1: \pi\neq0.9

Step-by-step explanation:

In this case we have to perform a hypothesis test on the proportion of the people owning cats.

The claim is that the proportion is significantly different than 905, what means it can be greater or smaller than 90% to reject the null hypothesis. Because of that, the null hypothesis has to state an equality (H0:p=0.9).

The right answer is Option B:

H_0: \pi=0.9\\\\H_1: \pi\neq0.9
