the following graph shows the number of soccer games a team won in each of their three seasons. Explain how you could redraw the graph so the change in wins between the three seasons does not seem so great.

Answers

Answer:

you can instead draw a 4x3 graph, and just shrink the width to make it look like there was a bigger dip in between seasons. so season 1 would be under the first box, the second season under the second box, and the third season under the third box. this would then make the slope downward to therefore make the graph look like a bigger drop

The answer is 15.

Step-by-step explanation:

Don't forget about the A and H equaling 5. That is there to throw you off. A and B equals 8. Right? Well that's the length. The the A and E is 3. Right? Well that's the height. what you do is cut the triangular prism in half and you end up with a triangular prism with a height of 5. Then you multiply that with 1.5. You get 1.5 by dividing 3 by 2.  You then get 7.5. Now multiply that with 2. Your final answer is 14.

The number of storybooks owned by eight classmates is shown below: 8, 9, 9, 7, 8, 6, 9, 8. The mean is 8 and Absolute Deviation= 0.

How to find the mean value of a data set?

The mean value of the data set is the ratio of the sum of the data set's values to number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

The number of storybooks owned by eight classmates is shown below:

8, 9, 9, 7, 8, 6, 9, 8

Part A:

[tex]\overline{x} = \dfrac{ 8+ 9+ 9+ 7+ 8+ 6+ 9+ 8}{8}[/tex]

Therefore, The mean is 8

Part B: Absolute Deviation= 0  

subtract each number by the mean

8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0

(then divide sum by mean) 0 divided by 8 = 8

An angle measures 48.4° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

The angles are 69.2 degrees and 20.8 degrees

Step-by-step explanation:

Complementary angles, when added together, = 90°

We’ll call the first unknown angle a and the second angle b

b = a - 48.4

a + b = 90

So let’s substitute in for b in the second equation:

a + a - 48.4 = 90

2a - 48.4 = 90

2a = 138.4

a = 69.2

69.2 - 48.4 = 20.8 = b

Now, does a + b = 90?

69.2 + 20.8 = 90

Jeff had $20. He spent 3/8 of his money on lunch. How much money does jeff have left?

Answers

Answer:

$12.50

Step-by-step explanation:

3/8 x 20/1 = 7.5

20 - 7.5 = 12.50

Jeff has $12.50 left after spending 3/8 of his money on lunch.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that Jeff had $20.

Jeff spent 3/8 of his money on lunch.

To find the money he left after spending on lunch we get by subtracting three by eight from one.

1 - 3/8

=8-3/8

= 5/8 of his money left.

To find out how much money Jeff has left, we can multiply the remaining fraction by his initial amount of money:

Intitial amount is 20

The money left is 5/8.

Multiply five by eight with twenty.

Money left = (5/8) × $20

Five divided by eight times of twenty.

=100/8

When hundred is divided by eight we get twelve point five.

= $12.50

Therefore, Jeff has $12.50 left after spending 3/8 of his money on lunch.
