Find The Area Of The Shaded Region. Use 3.14 As An Approximate For [tex]\pi[/tex] .nvm Not The Last Question

Answers

Answer 1

Step-by-step explanation:

For Big Circle

Radius (R) = 11yd

We know Area of a circle,

(A1) = πr²

(A1) = 3.14×11²

(A1) = 379.94yd²

For Small Circle

Radius (R) = 6yd

We know Area of a circle,

(A2) = πr²

(A2) = 3.14×6²

(A2) = 113.04yd²

Now,

Area of the shaded region = A1 - A2

= 379.94yd²-113.04yd²

= 266yd²

Therefore, Area of the shaded region is 266yd²

Identify the least value, first quartile, median, third quartile, and greatest value of the data.
5, 1, 4, 0, 9, 0, −8, 5, 2, 4, −1, 10, 7, −5

Answers

Answer:

least value=-8, Q1=-0.5, median=3, Q3=5, greatest value=10

Step-by-step explanation:

To find the least and greatest values, we simply look at the numbers in the data set and see that the least is -8 and the greatest is 10.

To find the first quartile, median, and third quartile, we need to put the data in order from least to greatest:

-8, -5, -1, 0, 0, 1, 2, 4, 4, 5, 5, 7, 9, 10

There are 14 numbers in the data set, so the median is the average of the 7th and 8th numbers, which is:

(median) = (2+4)/2 = 3

To find the first quartile, we need to find the median of the lower half of the data set. The lower half includes the first 7 numbers:

-8, -5, -1, 0, 0, 1, 2

The median of this lower half is the average of the 3rd and 4th numbers:

(first quartile) = (-1+0)/2 = -0.5

To find the third quartile, we need to find the median of the upper half of the data set. The upper half includes the last 7 numbers:

2, 4, 4, 5, 5, 7, 9, 10

The median of this upper half is the average of the 4th and 5th numbers:

(third quartile) = (5+5)/2 = 5

So the least value is -8, the first quartile is -0.5, the median is 3, the third quartile is 5, and the greatest value is 10.

What do we divide the numerator and denominator by to simplify
12/30 to lowest terms? (What is the largest number we can divide both the numerator and denominator by?)

Answers

Answer:

The factors of 12 are 1, 2, 3, 4, 6, and 12.

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.

The largest number that both 12 and 30 have in common is 6.

So, we can divide both the numerator and denominator by 6:

12/30 ÷ 6/6 = 2/5

Therefore, 12/30 simplified to lowest terms is 2/5.

Answer:

Divide the numerator and denominator by 6:

[tex] \frac{12}{30} = \frac{2}{5} [/tex]

Step-by-step explanation:

12 = 2 × 2 × 3

30 = 2 × 3 × 5

GCD of 12 and 30 = 2 × 3 = 6

Create a number line that represents the solution set of the inequality w divided by 7 > 38. Show all your work

Answers

Answer:

Step-by-step explanation:

To represent the solution set of the inequality w divided by 7 > 38 on a number line, we first need to isolate the variable w:

w/7 > 38

w > 7 x 38

w > 266

This means that any value of w greater than 266 satisfies the inequality.

We can represent this on a number line by marking a closed circle at 266 (since the inequality is not inclusive of this value), and drawing an arrow to the right to indicate all values greater than 266:

<--o======(266)---------------->

This represents the solution set of w/7 > 38.

Nadia is a stockbroker. She earns 12% commission each week. Last week, she sold $6,400 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?

Answers

Answer:

Nadia made a commission of 768 last week

The amount she made in 2011 is 40,045.824

Step-by-step explanation:

What is a commission?  

A commission is the fee got for the services, given by the percentage of the total worth.

If Nadia gets a 12% commission for $6400,

Commission = percentage ×  worth of stock

                    = 12% × 6400

                    = 768

There are 52.143 weeks per year.

The amount of commissions she made in 2011 is,

768 × 52.143 = 40,045.824

Hence, Nadia made a commission of $852 for $6400 worth of stocks. If she averages the same amount each week, Nadia made a commission of $40,045.824

nadia had made 768 in the last week. she made 40,046.24 in 2011
