Answer:

For 25, the answer is C

Step-by-step explanation:

How I got the answer for 25 is:

To find the mean absolute deviation of the data, start by finding the mean of the data set.

How you do this is first you need to find the sum of the data values, (add all the numbers together) and divide the sum by the number of data values.(and divide that number by how many numbers you added together in the first place)

In this case, we'd be adding 44 + 39 + 47 + 38 + 38 + 41 + 40, and that equals 287. Now we'll divide 287 by how many numbers we added together, which is 7 numbers. 287 ÷ 7 = 41. That's the mean of the data set.

Next, we'll find the absolute deviation of the mean. How we do this is, we find how far away all the numbers are from 41.

44 is 3 away from 41

39 is 2 away from 41

47 is 6 away from 41

38 is 3 away from 41

41 is 0 away from 41

40 is 1 away from 41

So now, we add all of the distances together (3, 2, 6, 3, 0, and 1), and that equals 15! Now we do 15 ÷ 6, which is 2.5 and the reason we're dividing by 6 is because we're dividing by the number of distances we added together. Now, if you look on your worksheet, the closest answer to 2.5 is C, (2.6) so I'd chose that as the correct answer. I hope that helped!

Answer:

96 cupcakes

Step-by-step explanation:

If they sold 4 times as many cupcakes as shamrock cookies, and they sold 24 shamrock cookies, then all you need to do is 24x4, which equals 96.

They sold a total of 18 dozens of chocolate chip cupcakes.

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of shamrock shaped cookies, y for horseshoe shaped cookies and z for mint chocolate cupcakes.

He sold a total of 24 dozens, hence:

x + y + z = 24  (1)

The sold 4 time shamrock shaped cookies as cupcakes, hence:

z = 4x   (2)

Also:

x = 3y   (3)

From the equations:

x = 4.5, y = 1.5 and z = 18

They sold a total of 18 dozens of chocolate chip cupcakes.

Answer:

b took test

Step-by-step explanation:

B. Organ systems must work together to keep the body functioning is the true statement of organ systems in the human body. Option B is correct.

Organ systems in the human body are composed of multiple organs that work together to carry out specific functions that are necessary for the survival and health of the organism

Here

Each system has specialized organs that are uniquely suited to carry out its specific functions. These systems are not self-sufficient, and they must work together to keep the body functioning. For example, the circulatory system, respiratory system, and digestive system all work together to deliver oxygen and nutrients to the cells of the body and remove waste products. This coordination and interdependence among organ systems is essential for the proper functioning of the human body.

Answer:

The real answer is 6

Step-by-step explanation:

Fairly simple. You know the length and the area, but you don't know the width. So your equation looks like this: 30 x ? = 180. But to figure out the width, you change the position of the numbers in the equation like this:

180 ÷ 30 = ?. Then you solve. 180 ÷ 30 = 6. If you want to double check your answer, you can plug in your answer to your original equation, 30 x 6 = 180.

Step-by-step explanation:

The ratio for Ms. Bojorquez is 32:28 which simplified is 8:7

The ratio for Ms. William is 104:98 which simplified is 52:49

Both these ratios cannot be simplified any further an after simplifying the ration, both are not equivalent therefore these are not equivalent ratios.

Answer:

z = -6

Step-by-step explanation:

5z + 2 = 3z - 10

Subtract 3z from both sides

2z + 2 = -10

Subtract 2 from both sides

2z = -12

Divide each side by 2

z = -6

So, the answer is z = -6

Answer:

24÷6= 4

Possible values of x are 6, 7 and 10.

Solutions of the inequality are 6, 7 and 10.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Given inequality

7 > z - 4

If x = 6; x - 4 = 2 < 7

x = 7; 7 - 4 = 3 < 7

x = 10; 10 - 4= 6 < 7

x = 11; 11 - 7 = 7 not less than or equal to 7

Thus, possible values of x are 6, 7 and 10.

Answer:

Varsity has a larger IQR

Step-by-step explanation:

Answer: well what are my choices?

Step-by-step explanation:

Answer:

Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.

The school decided to cover the semicircles with grass to create a space for stretching and other activities.

To Find: area of one of the semicircles at either end of the track

How many square yards of grass will the school need to cover the entire circle?

Solution:

Diameter of semicircle = 70 yards

Radius of semicircle = 70/2 = 35 yards

Area of semicircle at one end = (1/2)πr²

= (1/2)(22/7)35²

= 1,925 sq yards

area of one of the semicircles at either end of the track = 1,925 sq yards

square yards of grass will the school need to cover the entire circle

= 2 x   1,925

= 3850 sq yards

distance around one of the semicircles at either end of the soccer field = πr  = (22/7) 35 = 110 yards

distance around the inner lane of the track  = 100 + 100 + 110 + 110

= 420 yards

We need to do 90-61, which is 29. X = 29, because the base of 61 and the right of the x is equal to a right angle.

Answer:

x=29 degrees

Step-by-step explanation:

Both angles shown ad up to a 90 degree angle. We can see this because on the adjacent side there is a box indicating that it is a right angle. The three angles add up to 180, thus if we subtract 90 degrees due to the angle on the left of the y axis, the angles on the right of the y axis must add up to 90 as well.

Since the angles on the right must add up to 90, we set an equation to solve for x:

61+x=90(subtract 61)

x=29 degrees
