There's been a zombie outbreak! There are three major U.S. cities that have been affected: Atlanta,
Chicago, and New York City. Your group at the Center for Disease Control (CDC) has been
dispatched to each city. Read the scenarios below...
Atlanta - Each day, the original zombie infected 400 people and infects people at a constant rate
of 10 people per day. New zombies cannot infect anyone.
1. Do the zombie attacks appear to be linear, quadratic, exponential?
2.Create the equation for this scenario
3. Predict how many people would get infected by Day 15
4. If the population of the city is 488,800 people, how long would it take to infect the whole city?
Can someone answer all of these pleasee

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 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

|5 - 5.5| = 0.5

|6 - 5.5| = 0.5

|7 - 5.5| = 1.5

|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).

j = f-24

Substitute the second equation into the first

f-24 +f = 58

2f -24= 58

Add 24 to each side

2f = 58+24

2f =82

So, since the scale factor is 1 : 12, the model is 1/12 of the actual. So, multiply:

6.25 * 12 = 75

So, the actual length would be 75 inches.

To check:
