Answer:

  (d)  2/3(11)

Step-by-step explanation:

The height of the cylinder is h=2r, so the volume of the cylinder in terms of radius is ...

  V = πr^2·h = πr^2·(2r) = 2πr^3

The volume of the sphere is given by the formula ...

  V = (4/3)πr^3

So, the ratio of the sphere volume to the cylinder volume is ...

  sphere volume / cylinder volume = ((4/3)πr^3)/(2πr^3) = (4/3)/2 = 2/3

That is, the sphere volume is ...

  sphere volume = (2/3) × (cylinder volume)

  V = (2/3)(11)

Can someone solve this please?
Hunter-Best [27]

Answer:

3.16 units

Step-by-step explanation:

The distance between the points P1 (6, 8) and P2 (7, 5)) can be solved by using the distance formula given as d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.

Let,

(6, 8) = (x_1, y_1)

(7, 5) = (x_2, y_2)

Plug these values into the distance formula.

Thus:

d = \sqrt{(7 - 6)^2 + (5 - 8)^2}

d = \sqrt{(1)^2 + (-3)^2}

d = \sqrt{1 + 9}

d = \sqrt{10} =

d = 3.16 (nearest tenth)

Distance between the two points in the graph is approximately 3.16 units

Write the following using index notation<br><br> 9 x 7 x 9 x 9 x 7 x 9​
Vikentia [17]
We just have to group the like terms together. So there are 4 nines and 2 sevens.

That would make it; 9^4 x 7^2

9 to the power of 4 multiplied by 7 to the power of 2(the second power).

Find the exact length of the third side
devlian [24]
You can use the Pythagorean theorem, a^2+b^2=c^2, to solve this.

b= square-root of (c^2)-(a^2)

b= square-root of (9^2)-(2^2)

b= 8.77.... which in the exact form is square root of 77.

True or False: A p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is f
professor190 [17]

Answer:

False

Step-by-step explanation:?

The hypothesis tests compare weather an event is meant to alter a population mean results, for example, a scientist experiment might have or not have a significant effect over the population results. The test aims to reject the null hypothesis, so what it really want to find out is if the alternative Hypothesis H1 is likely true. The null hypothesis is the probability that the results are not due to chance – if it’s rejected, then the results are due to chance.The level of significance , or so called p-value, is the probability that the null hypothesis (H0) happen , If p is very small then the null hypothesis is rejected - isn’t true- and the alternative Hypothesis is accepted. A higher P value implies a higher probability than results are not happening so that the H0 is accepted and H1 rejected. The null Hypothesis will normally will rejected when the level of significance are either lower than 0.05 or 0.01, the lower P value the higher the level of confidence that the results are due to chance.

Since the first part of the statement (A p is the probability that the results are not due to chance) is correct, and the second part is wrong (…the probability that the null hypothesis (H0) is false), the total statement is false. The correct statement would be as follows : A p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is true.

Joseph claims that a scatterplot in which the y-values increase as the x-values increase must have a linear association. Amy cla
quester [9]

Answer:

Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.

Step-by-step explanation:

I just took the quiz, I hope this helps :).
