Choose The Correct Formulas For The Solid.Lateral Surface Area Of A Cylinder

Answers

Answer 1

Answer:

The last one

Step-by-step explanation:

The 2πrh bit calculates the area of the rectangle at the middle by multipling its height (h) and its width (2πr which is also the circumference of the top and bottom circles) the second 2πr² bit is the areas of the two circles which both have areas πr² so when you have two its πr²+πr² which is 2πr²

The measure of the variation of the data is 2.2 hours.

How to calculate the mean average deviation?

The dot plot shows the weekly biking times (in hours). To describe the center, the most appropriate measure is the median, since the distribution appears to be roughly symmetric.

To find the median, we arrange the data in order from smallest to largest:

2, 4, 4, 5, 6, 7, 8, 8, 9, 10

There are 10 data points, so the median is the average of the fifth and sixth values:

median = (5 + 6) / 2 = 5.5

So, the measure of the center of the data is 5.5 hours.

To describe the variation, the most appropriate measure is the mean absolute deviation (MAD), which measures the average distance of each data point from the median.

To calculate the MAD, we first find the deviations of each data point from the median:

|2 - 5.5| = 3.5

|4 - 5.5| = 1.5

|4 - 5.5| = 1.5

|5 - 5.5| = 0.5

|6 - 5.5| = 0.5

|7 - 5.5| = 1.5

|8 - 5.5| = 2.5

|8 - 5.5| = 2.5

|9 - 5.5| = 3.5

|10 - 5.5| = 4.5

Next, we find the average of these deviations:

MAD = (3.5 + 1.5 + 1.5 + 0.5 + 0.5 + 1.5 + 2.5 + 2.5 + 3.5 + 4.5) / 10

MAD = 2.2

So, the measure of the variation of the data is 2.2 hours (rounded to the nearest tenth).

What are the coordinates of the vertices of a rectangle with an perimeter of 12 units and an area of 5 sq. units.

Answers

Answer: The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The area of the rectangle is A = L w, A = 8 x 5 = 40 units to the 2nd power

Step-by-step explanation:

In order to solve this problem you need to find the distances between the vertices. By inspection the points (5,3) and (5,-2) form one the of the rectangle w = √ ( 5-5)2 + ( -2-3)2 = 5

The length can be obtained by finding distance between the points (5,3) and ( -3,3),

L = √(3-3)2+(-3-5)2 = 8

= 26 units

The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The rectangle is the quadrilateral with 4 right angles. It could also be defined as, an equiangular quadrilateral, since equiangular means that the all of this angles are = (360°/4 = 90°); and the parallelogram containing a right angle. A rectangle with 4 sides of equal length is a square. The term oblong is occasionally used to refer to a non square rectangle.

The area of rectangle is A = L w, A = 8 x 5 = 40 units to the 2nd power

In order to solve this question you want to find the distances between the vertices. By inspection the points (5,3) and (5,-2) form 1 the of the rectangle w = √ ( 5-5)2 + ( -2-3)2 = 5

The length can be obtained by finding distance between the points (5,3) and ( -3,3),

L = √(3-3)2+(-3-5)2 = 8

In 1 box, there are 3 red, 11 white, 8 black, 2 navy and 6 brown socks. What is the probability of randomly picking a white sock, putting it back, and then randomly picking a brown sock?

Answers

Answer 11/150

Explanation: you have 30 socks in all and 11 of them are white that means 11/30 since you replaced the sock or put it back you still have 30 socks and out of those 30 socks there are 6 brown socks basically 6/30 (simplified it is 1/5) you must multiply 11/30 and 1/5 and that gives you 11/150

It does not use encumbrance accounting in the Capital Projects Fund. The following transactions occur: 1. On January 1, 2013, Marilyn County issues general obligation bonds in the amount of $1,000,000 to build a community center.

The county realizes that the community center will cost more than it originally anticipated. On May 1, the county transfers $20,000 from its General Fund to its Capital Projects Fund to help meet project costs. 3. Construction is completed on July 1, 2013, and the community center is ready for occupancy. The county pays the contractor a total of $1,020,000 on July 1. The county anticipates that the community center will have a useful life of 20 years. 4. On September 30, 2013, the General Fund transfers an amount to the Debt Service Fund that is sufficient to pay the first debt service installment, which is due October 1. 5.
