Hellppp Please!!! Find The Area Of The Shaded Region

Answers

Answer 1

Answer:

1600-400pi

Step-by-step explanation:

There are 2 semicircles making it a full circle. We are doing (40*40)-the area of the circle. We do 20*20 since that it is the radius and get 400. We then multiply it by pi. We get 400pi. Now we find the area of the square. This is 40*40 which gives us 1600. 1600-400pi is our answer

The ordered pair (15, 12) means that 15 pounds of beans cost $12.

Step-by-step explanation:

Ordered pairs are in the format of (x,y). The first number represents a point's position on the x-axis and the second represents a point's position on the y-axis. Also note that in this graph, the x-axis represents the weight of beans in pounds and the y-axis represents the cost of beans.

Knowing this, (15,12) means that 15 pounds of beans must cost $12.

15 pounds cost $12.

A ball is drawn from a bag of 26 red and 12 yellow balls. The process is repeated 50 times, replacing each ball that is drawn. Which of the following statements about the distributions of counts and proportions is true?A. The count of drawing a yellow ball is not a binomial distribution.B. The count of drawing a red ball is a binomial distribution.C. The distribution of the count of drawing a red ball cannot be approximated with a normal distribution D. The distribution of the count of drawing a yellow ball from a sample size of 10 can be approacimated with a normal distribution.

Answers

Answer:

B. The count of drawing a red ball is a binomial distribution.

Step-by-step explanation:

The count of drawing a red ball can be gotten by binomial distribution because:

the chance of success; p = 26/50 and chance of no failure; q = 24/50

For example, If we want to find probability of getting 5 red balls out of 20 selections, we will use the binomial probability distribution formula;

P(X = 5) = C(20, 5) × p^(5) × q^(20 - 5)

This same procedure also applies if we want to get the probability of getting a number of yellow balls out of a number of selections from the bag.

Looking at the options, the best option that explains how it's binomial probability that works is option B

Let V(t) represent the values of a bank account, in thousands dollars, t years after the account is opened at the bank. Determine whether each statement below is true

Answers

Complete question is;

Let V(t) represent the value of a bank account, in thousands of dollars, t years after the account is opened at the bank. Determine whether each statement below is true. Select True or False for each statement.

V(0) = 2 means that the value of the bank account when it is opened is $2000

V(5) = 2.2 means that 2.2 years after the bank account is opened, its value is $5000

V(10) – V(5) = 0.4 means that the bank account grows by $400 between 5 and 10 years after its opening

Answer:

Statement 1: True

Statement 2: False

Statement 3: False

Step-by-step explanation:

We are told that the function V(t) represents the value of a bank account, in thousands of dollars, t years after the account is opened at the bank.

This means that if V(10) = 50, it means that the bank account is valued after 10 years is $50,000

From this little explanation, it's clear that only statement 1 is correct.

Megan went to the store and bought 4 notebooks and 9 pencils for a total of $8.25. Joanne went to the same store and bought 7 notebooks and 14 pencils for a total of $14. What was the price per pencil and the price per notebook?

Answers

Let notebooks be x and let pencils be y

4x+9y=8.25 (equation 1)
7x+14y=14.00 (equation 2)

Multiply equation 1 by 7
So that you get 28x+63y=57.75

Multiply equation 2 by 4
So that you get 28x+56y=56.00

28x+63y=57.75 -
28x+56y=56.00
-----------------------
7y=1.75

Divide both sides by 7
1.75/7 is 0.25

So, now we know that one pencil costs 0.25 cents

Sub this y value into equation one

4x+9(0.25)=8.25

4x+2.25=8.25

Move 2.25 to the other side as a negative number

4x= 6

Divide both sides by 4

6/4 is $1.50

So, one pencil is equal to 0.25 cents and one notebook is equal to $1.50

h (x) =4x-2 complete the function table

Answers

Note:

You did not mention the table of the points. But, I would try to clear your concept by taking 6 sample points.

Answer:

The table and the graph of the function h(x) = 4x-2 is also attached below.

Step-by-step explanation:

Given the function

[tex]h(x) = 4x-2[/tex]

substituting x = 0 in the function

h(0) = 4(0) -2 = 0 -2 = -2

Therefore, the point (0, -2) satisfies on the function.

substituting y = 1 in the function

h(1) = 4(1) -2 = 4 -2 = 2

Therefore, the point (1, 2) satisfies on the function.

substituting y = 2 in the function

h(2) = 4(2) -2 = 8 -2 = 6

Therefore, the point (2, 6) satisfies on the function.

substituting y = 3 in the function

h(3) = 4(3) -2 = 12 -2 = 10

Therefore, the point (3, 10) satisfies on the function.

substituting y = 4 in the function

h(4) = 4(4) -2 = 16 -2 = 14

Therefore, the point (4, 14) satisfies on the function.

substituting y = 5 in the function

h(5) = 4(5) -2 = 20 -2 = 18

Therefore, the point (5, 18) satisfies on the function.

Therefore, we conclude that table:

x                  h(x) = 4x-2

0                  -2

1                    2

2                   6

3                   10

4                   14

5                   18

The graph of the function h(x) = 4x-2 is also attached below.

Answer:

Put the arrow facing the left with a non-filled up dot at the point between 31 and 32.

Step-by-step explanation:

x < 31.5 means that x is lesser than 31.5 and so x cannot be 31.5 itself.

< means lesser.

> means more than.

A filled up dot means that the number itself is included in the values of x.

A non-filled up dot means that the number itself is not included in the values of x.

An arrow facing left means lesser than that number.

An arrow facing right means more than that number.

Since 31.5 is not included in the values of x, we will be using the non-filled up dot.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

3x - y = 10

2x - y =  7

Step 2: Rewrite Systems

3x - y = 10

Subtract 3x on both sides:                    -y = 10 - 3xDivide -1 on both sides:                         y = 3x - 10

Step 3: Redefine Systems

y = 3x - 10

2x - y = 7

Step 4: Solve for x

Substitution

Substitute in y:                    2x - (3x - 10) = 7Distribute -1:                        2x - 3x + 10 = 7Combine like terms:           -x + 10 = 7Isolate x term:                     -x = -3Isolate x:                              x = 3

Step 5: Solve for y

Define equation:                    3x - y = 10Substitute in x:                       3(3) - y = 10Multiply:                                  9 - y = 10Isolate y term:                         -y = 1Isolate y:                                 y = -1

a retailer makes a profit of 5% by selling a fan for Rs 735 at what price did he purchase the fan​​

Answers

Answer:

[tex]\large\boxed{\pink{\sf \leadsto He \ purchased \ the \ fan \ for \ Rs 700. }}[/tex]

Step-by-step explanation:

Given that , a retailer makes a profit of 5% by selling a fan for Rs 735 . So let us take CP be x .

Now , here

[tex]\implies \red{\sf Profit \ made \ by \ retailer = 5\% }[/tex]

Here we assumed CP to be x , and profit % is 5% . So , its SP will be

[tex]\implies SP = CP + 5\% \ of \ CP \\\\\implies Rs 735 = x + \dfrac{5}{100}x \\\\\implies \dfrac{100x+5x}{100}= Rs 735 \\\\\implies \dfrac{105x }{100}= Rs 735 \\\\\implies x = \dfrac{735\times 100}{105} \\\\\underline{\boxed{\orange{\tt \implies x = Rs 700 }}}[/tex]

Hence the CP of the fan was Rs 700 .

The table shows the number of points the Lions scored and allowed in 8 games. Based on the data, which sentence is true? The median for points scored is greater than the median for points allowed.

The range for points scored is greater than the range for points allowed.​

Answers

Answer:

The range for points scored is greater than the range for points allowed.

Step-by-step explanation:

Points scored: 175

Points allowed: 168

The true sentence is that the range for points scored is greater than the range for points allowed.

What is mean?

The mean of observations is equal to the ratio of sum of all the observations and the number of observations.

Points scored by the lion in the 8 games are

24 + 21 + 18 + 17 + 24 + 31 + 22 + 28 = 175.

Points allowed in the 8 games are

16 + 10 + 27 + 21 + 21 + 24 + 28 = 168

Thus, the range for points scored is greater than the range for points allowed.​
