Answer:

y = 9

Step-by-step explanation:

-2(20) + 4y = -4

-40 + 4y = -4

4y = -4 + 40

4y = 36

4/4 = y

36/4 = 9

y = 9

Hope this helped! :)

The volume of a rectangular prism is 16.328 cm³. The height is 3.14 cm.

Ghella [55]

Answer:

The area of the base is = 5.2 cm²

Step-by-step explanation:

First, we need to know the formula to calculate volume:

$volume=height XBase area$

if we change to our equations to the values we know:

$16.328 = 3.14XB$

Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:

$\frac{16.328}{3.14} =B$

We calculate the operation=

$\frac{16.328}{3.14} =5.2$

And the answer is 5.2 cm²

Select the correct answer. which data set is the farthest from a normal distribution? a. 2, 3, 3, 4, 4, 4, 5, 5, 6 b. 3, 4, 5, 6

tigry1 [53]

The answer choice which is the farthest from a normal distribution is; Choice E; 2, 4, 5, 5, 6, 6, 7, 7, 7, 8, 8, 9, 9, 10.

<h3>Which data set is farthest from a normal distribution?</h3>

A normal distribution, is a data set which when graphed must follow a bell-shaped symmetrical curve centered around the mean. Additionally, such distribution must adhere to the empirical rule that indicates the percentage of the data set that falls within (plus or minus) 1, 2 and 3 standard deviations of the mean.

On this note, upon evaluation of the data sets, it follows that answer choice E represents the data set that's most farthest from a normal distribution.

A spheres radius is multiplied by 2. How is it’s surface area affected

dexar [7]

Answer:

The surface area is multiplied by 3.

Step-by-step explanation:

If r is the radius of a sphere its surface area = 4(pi)r^2. If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2. So the surface area becomes 4-fold or the increase in surface area is 300%.
