There’s a 30% difference between the percent of increase and percent of decrease. There is a 50% increase when it goes from 30 to 45. And a 20% decrease from 45 to 36.

Answer:

30%

Step-by-step explanation:

The increase was 15/30 = 50%,

The decrease was 9/45 = 20%.

50% - 20% = 30%

Which of the statements are true regarding dot plots bar graphs and historgrams
andrey2020 [161]

the only statement that is true is the one in option D.

"Bar graphs are used to represent data that is discrete".

<h3>Which of the statements are true regarding dot plots, bar graphs, and histograms?</h3>

Dot plots,  bar graphs, and histograms are used to repersent graphically data sets.

Thus, what these graphs do represent are populations in a data set with a given property.

Remember that data is usually discrete, so we usually use dot plots and bar graphs to represent discrete data.

Histograms show distributions of numerical data (it can be used for continuous or discrete data).

With all that in mind, we conclude that the only statement that is true is the one in option D.

"Bar graphs are used to represent data that is discrete".

#3 AB and AD are tangent to the circle centered at point C. Find the value of x. *
dezoksy [38]

Answer:

x=4

Step-by-step explanation:

tangent lines from the same point to a circle are congruent in length, so we can say that

5x+8 = 8x-4

5x -5x +8 = 8x - 5x -4

8 = 3x - 4

8+4 = 3x -4 + 4

3x = 12

3x/3 = 12/3

x=4

1.)A rectangle has an area of 72 square centimeters and the length is twice the width. The perimeter of the rectangle
Greeley [361]

1.

area = L x w = 72

L = 2w

72 = 2w*w = 2w^2

divide by 2

36 = w^2

w = sqrt(36) = 6 

l = 2*6 =12

perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36


2.

sqrt(40)= 6.324555 cm ( round to 6.32 )

6.32 - 4 = 2.32 cm original length of a side

The weights of professional wrestlers are approximately normally distributed with a mean of 220 pounds and a standard deviation
nikdorinn [45]

Answer:

1.6%

Step-by-step explanation:

The cumulative distribution function (CDF) of a random variable X is denoted by F(x), and is defined as

F(x) = P(X ≤ x). where x is the largest possible value of X that is less than or equal to x

z = (x-μ)/σ,

where:

x is the raw score = 205

μ is the population mean, = 220 pounds

σ is the population standard deviation = 7 pounds

205 -220/7

z = -15/7

z = -2.1428571429

Using the normal cdf function on your graphing calculator,the cumulative distribution is

normalcdf( -2.1428571429, 100)

= 0.01606229

In percent form = 0.01606229 × 100

= 1.6%
