Find the best measure of variability for the data and determine which player was more consistent.
Player B is the most consistent, with an IQR of 3.5.
Player B is the most consistent, with a range of 10.
Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.

Answers

Answer: Player B is the most consistent, with an IQR of 3.5.

Step-by-step explanation:

For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).

For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).

Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

Step-by-step explanation:

To start working, times everything in parenthesis by 2

2 times x = 2x

2 times 3.5 is 7

Now that you have that, re-write the equation

2x+7=-10

subtract 7 from 7 and -10

you get 2x=-17

divide both sides by 2

x=-8.5

Answers

Answer:

4 inches wide

Step-by-step explanation:

We see that 984 ÷ 328 = 3, so the real Eiffel Tower is 3 times as tall as it is wide. So the scale model must also be 3 times as tall as it is wide. If the scale model is 12 inches tall, then it is 12 ÷ 3 = 4 inches wide.

4 inches

984/12=82
328/82= 4
4 inches is the width

A composite figure has a radius of 10 cm.

A circle with radius of 10 centimeters. One-quarter of the circle is cut out of the figure.

What is the area of this composite figure? Use 3.14 for Pi.
23.55 centimeters squared
78.5 centimeters squared
235.5 centimeters squared
314 centimeters squared

Answers

Answer:

C, 235.5 cm^2

Step-by-step explanation:

Formula for area of circle:

A = πr^2

Where π represents pi(3.14 or 22/7) and r represents the radius.

Plug in given value (10):

A = πr^2

A = 3.14(10)^2

A = 3.14(100)

A = 314

Now they say a quarter of this circle is cut out, which means we have to first find out what a quarter of this area is:

314/4

= 78.5

A quarter of this circle is 78.5, so let's subtract this from the total area (314):

314 - 78.5

= 235.5 cm^2

The area is 235.5 centimeters squared.

Two friends plant a tree and record the height of the tree each following year to track its growth. The data can be represented by the linear model y = 4.3z +3.25, where y represents the height of the tree, in feet, and z represents the number of years since it was planted.
Based on the linear model, what is the expected height of the tree in 8 years?

3.25
4.3
31.2
37.65

Answers

Answer:

D.) 37.65

Step-by-step explanation:

I know that 8 is an input based on this word problem. So, then I plug in the 8 for z and solve to find the expected height of the tree in 8 years.

y=4.3z+3.25

y=4.3(8)+3.25

y=34.4+3.25

y=37.65

In 8 years the expected height of the tree is 37.65

The answer is D. 37.65

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500
