Find the slope between the points (2, -10) and (-4, 2). A) 1/4 B) -2 C) 4 D) -1/2

Find the volume of the cone. Round your answer to the nearest tenth.

oee [108]

Answer:

15205.3

Step-by-step explanation: H=30 R²=484 3.14=π →= rounded up to tenth V = Volume

formula (no numbers): H x R² x π ÷  $\frac{1}{3}$  (or 3) = V

how i got the answer : 30 x 484 x 3.14 ÷ 3 = 15205.31 → 15205.3

At the end of a meal in a restaurant, a person wants to have pie a la mode (pie topped with ice cream) for dessert. there are 5

JulsSmile [24]

1/5x1/2=1/10

1/5 because there are 5 flavors.
1/2 because there are 2 kinds of pies.
So the answer is 1/10.

Hope this helps.

Restaurateur Denny Valentine is evaluating two sites, Raymondville and Rosenberg, for his next restaurant. He wants to prove tha

Aleksandr-060686 [28]

Answer:

$\bar X_1$ represent the sample for the sample 1

$\bar X_2$ represent the sample for the sample 2

$s_1$ represent the deviation for the sample 1

$s_2$ represent the deviation for the sample 2

$n_1 = 81$ represent the sample size for the group 1

$n_2 = 81$ represent the sample size for the group 2

And on this case if we create the system of hypothesis we have this:

Null hypothesis : $\mu_1 -\mu_2 \leq 0$

Alternative hypothesis: $\mu_1 -\mu_2 >0$

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

On this caseHe wants to prove that Raymondville residents (population 1) dine out more often than Rosenberg residents (population 2). So this statement need to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.

Solution to the problem

We assume that we have the following statistics:

$\bar X_1$ represent the sample for the sample 1

$\bar X_2$ represent the sample for the sample 2

$s_1$ represent the deviation for the sample 1

$s_2$ represent the deviation for the sample 2

$n_1 = 81$ represent the sample size for the group 1

$n_2 = 81$ represent the sample size for the group 2

And on this case if we create the system of hypothesis we have this:

Null hypothesis : $\mu_1 -\mu_2 \leq 0$

Alternative hypothesis: $\mu_1 -\mu_2 >0$

Suppose a circle has a radius of 13 inches. How far would a 24 inch chord be from the center of the circle? (Hint: Draw a diagra

lys-0071 [83]

Answer:

Step-by-step explanation:

Directions

Draw a circle
Dear a chord with a length of 24 inside the circle. You just have to label it as 24
Draw a radius that is perpendicular and a bisector through the chord
Draw a radius that is from the center of the circle to one end of the chord.
Label where the perpendicular radius to the chord intersect. Call it E.
You should get something that looks like the diagram below. The only thing you have to do is put in the point E which is the midpoint of CB.

Givens

AC = 13 inches Given

CB = 24 inches Given

CE = 12 inches Construction and property of a midpoint.

So what we have now is a right triangle (ACE) with the right angle at E.

What we seek is AE

Formula

AC^2 = CE^2 + AE^2

13^2 = 12^2 + AE^2

169 = 144 + AE^2 Subtract 144 from both sides.

169 - 144 = 144-144 + AE^2 Combine

25 = AE^2 Take the square root of both sides

√25 = √AE^2

5 = AE

Answer

The 24 inch chord is 5 inches from the center of the circle.
