Answer:

area of circle having radius 3

is πr²=π*3²=9π square units

area of circle having radius 2

=πr²=π×2²=4π square units

again

area of big circle having radius [3+2]=5 units

=πr²=π×5²=25π square units

Now

<u>area</u><u> </u><u>of</u><u> </u><u>shaded</u><u> </u><u>region</u><u>=</u><u>2</u><u>5</u><u>π</u><u>-</u><u>4</u><u>π</u><u>-</u><u>9</u><u>π</u><u>=</u><u>1</u><u>2</u><u>π</u><u> </u><u>or</u><u> </u><u>3</u><u>7</u><u>.</u><u>7</u><u>s</u><u>q</u><u>u</u><u>a</u><u>r</u><u>e</u><u> </u><u>units</u><u>.</u>

Answer:

37.7 sq units

Step-by-step explanation:

Find area if entire region then subtract out each smaller circle

Diameter of entire circle would be 3(2)+2(2) which is 10 so radius is 5

Area of entire region = 25π

Area of circle one = 9π

Area of circle two = 4π

Area of shaded region = 25π - 13π which is 12π or 37.7

(3x - 4x - 2 + 3x - 6 = 180<br> 7x – 8 =
skelet666 [1.2K]
If we collect like terms of the first equation, we can simplify to

2x - 8 = 180

If we add 8 to both sides, we get

2x = 188

And that means x = 94

If we substitute this into the second equation, we get

7(94) - 8 = ?

7 x 94 is equal to 658

658 - 8 = 650

A manufacturer has invested $120,000 in a new product and wants to set a price to earn a $80,000 profit. The variable cost per u
Misha Larkins [42]

Answer: 500

Step-by-step explanation:

The remainder of the question is:

How many units does the company need to sell to reach the target profit?

The required sales to break even will be calculated as:

= (Fixed cost + Required profit) / ( Price per unit - Variable cost)

= (120000 - 80000) / (100 - 20)

= 40000/80

= 500

The company needs to sell 500 units.

In your own words, how do you create a residual plot that shows whether a linear model is an appropriate fit for the data?
tresset_1 [31]

Step-by-step explanation:

We need to understand what residual plot is?

A residual plot is a graph that shows the residuals on the vertical axis and the independent variable on the horizontal axis.

Hence, there are 2 cases related to the relation between residual plot and a linear model:

1. If the points in a residual plot are randomly dispersed around the horizontal axis => the linear model is an appropriate fit for the data

2. If the points in a residual plot has a pattern => nonlinear model is more appropriate or the line have a bad fit with the set of the data.

Hope it will find you well.

The number of players in the league is the product of the number of payers in each team and the number of teams in the league.

This the expression to obtain the total number of players goes thus :

Total number of players in the league = 20 * m

Total Numbr of players in the league = 20m
