Answer is provided in the image attached.
A drawer contains 4 black socks, 3 white socks, and 2 red socks. One sock is drawn from the drawer and kept. The second sock is drawn from the drawer. What is the probability that they are both white?
The probability that they are both white if the first sock is kept and second is drawn will be 8.33%.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
A drawer contains 4 black socks, 3 white socks, and 2 red socks.
One sock is drawn from the drawer and kept.
The second sock is drawn from the drawer.
The total number of the event will be
Total event = 9
Then the probability that they are both white will be
P = (3/9) (2/8)
P = (1/3)(1/4)
P = 1/12
P = 0.0833
P = 8.33%

The probability of drawing two white socks from the drawer is 2/27.
Explanation:To find the probability that both socks drawn are white, we need to find the probability of drawing a white sock on the first draw and then drawing another white sock on the second draw.
There are a total of 9 socks in the drawer (4 black, 3 white, and 2 red).
The probability of drawing a white sock on the first draw is 3/9 (3 white socks out of 9 total socks).
After replacing the first sock, the total number of socks remains the same, but the number of white socks decreases to 2. So the probability of drawing a white sock on the second draw is 2/9.
Now, to find the probability of both events happening, we multiply the probabilities together: P(First white sock) * P(Second white sock) = (3/9) * (2/9) = 6/81 = 2/27.
Therefore, the probability that both socks drawn are white is 2/27.

f(2)=?
Answer:
f(2) = 0
Step-by-step explanation:
Function f(t) is defined in three different ways depending on the value of t.
For t = 8, function f(t) is -64/t.
For t = 10, function f(t) is 14 - t.
We are not asked about f(8) or f(10). We are asked about f(2). The third definition of function f(t) is for all values of t that are not 8 or 10. 2 is not 8 or 10, so use the third definition of function f(t) and plug in 2 for t.
f(t) = t^2 - 3t + 2 for t not equal to 8 or 10.
f(2) = 2^2 - 3(2) + 2
f(2) = 4 - 6 + 2
f(2) = 0

What area is a circle?A circle's area is equal to pi times the radius squared (A = r2).The following formulas can be used to determine a circle's area: Area is equal to r2, where r stands for radius.What is area of rectangle?When calculating the area of a rectangle, we multiply its length by its breadth.A = lw, where l and w are the length and width of the rectangle (rectangle)
In this question we simply calculate area of circle where r=5 , and area of rectangle l = 2 and b = 1.
Area of circle = πr²
= [tex]\frac{22 *5*5}{7}[/tex] = 78.57
Area of rectangle = l * b
2 * 1 = 2
Then simply subtract area of rectangle to area of circle .
Area of shaded blue = 78.57 - 2
= 76.57 ⇒ 77 in²
Therefore, The approximate area that is shaded blue 77 in².

There are 9 players on a baseball team. In how many different ways can the coach choose players for first base, second base, third base, and shortstop?
There are 3,024 different ways the coach can choose players for first base, second base, third base, and shortstop from a team of 9 players.
Since the positions are distinct (first base, second base, third base, and shortstop), and each position can only be filled by one player, we can use the permutation formula to calculate the number of arrangements.
The coach has 9 players to choose from for the first position.
After selecting one player for first base, there remain 8 players for the second position, 7 players for the third position, and 6 players for shortstop.
The total number of different ways the coach can choose players for the four positions is obtained by multiplying these numbers:
9 x 8 x 7 x 6 = 3,024
Hence, there are 3,024 different ways.

Josh is having issues with his over-the-range microwave, and must decide to either have it repaired or replaced. After doing some research, he's determined that if he has to spend $200 or more on repairs, the better decision would be to replace the microwave. The appliance repair company will repair his microwave for a service call fee of $89, a parts fee of $41, and a charge of $17.50 for every 15 minutes of labor. If x represents the number of 15-minute intervals of labor, which inequality represents the number of allowable 15-minute intervals before replacing the microwave becomes the better decision? Assume that Josh won't be charged for a 15-minute interval until the full 15 minutes of labor is used.
Answer:
the inequality would be: 89+41+17.50x Is less than 200
Step-by-step explanation:
add all of the numbers together and the x with the 17.50. Add a less than inequality sign, then 200, which represents how much it would be for repairs
Answer:
[tex]130+17.50x \leq 200[/tex]
Step-by-step explanation:
The appliance repair company will repair his microwave for a service call fee of $89, a parts fee of $41, and a charge of $17.50 for every 15 minutes of labor.
If Josh spends $200 or more on repairs, he will replace the microwave.
Let x represents the number of 15-minute intervals of labor.
So, as per the scenario, the inequality becomes:
[tex]89+41+17.50x \leq 200[/tex]
=> [tex]130+17.50x \leq 200[/tex]
Solving for x
[tex]17.50x \leq 200-130[/tex]
[tex]17.50x \leq 70[/tex]
[tex]x \leq 4[/tex]
Hence, up to 4, 15 minutes interval that is one hour. the repair cost will be up to $200.
But after this it will cost more. Hence, Josh can opt for replacing after 4, 15 minutes intervals.

Hiro has a stack of cards with one number from the set 1, 1, 2, 2, 3, 3, 3, 4 written on each card. What is the probability that he pulls out a 3 first and then pulls out a 2 without replacing them?
Answer:
3/28
Step-by-step explanation:
Given in the question that,
stack of cards have numbers (1, 1, 2, 2, 3, 3, 3, 4)
Total number of cards = 8
Number of card with 3 on them = 3
Number of card with 2 on them = 2
To find the probability that he pulls out a 3 first and then pulls out a 2, we will multiple the probability of having 3 with 2.
Probability of having 3 = 3/8
Probability of having 2 = 2/7 (without replacing)
3/8 x 2/7 = 3/28
Thus, the answer is 3/28
Answer:3/28

What is the mean absolute deviation of the data set?
(21, 22, 24, 26, 27, 28, 20, 303
2
3

Answer:
3
Step-by-step explanation:
The mean absolute deviation of the data set is approximately 3.09.
The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations in a data set and their mean.
To calculate the MAD, you first need to find the mean of the data set. In this case, the mean is 31.375.
Then, you calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).
Once you have calculated the absolute deviation of each data point, you find the average of those absolute deviations. This is the mean absolute deviation.
In the example data set, the mean absolute deviation is approximately 3.
Find the mean of the data set: (21 + 22 + 24 + 26 + 27 + 28 + 20 + 30) / 8 = 31.375
Calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).
Add up the absolute deviations of all the data points. In this case, the sum of the absolute deviations is 24.75.
Divide the sum of the absolute deviations by the number of data points to find the mean absolute deviation. In this case, the mean absolute deviation is 24.75 / 8 = 3.09375.
Therefore, the mean absolute deviation of the data set is approximately 3.09.
The complete question is:What is the mean absolute deviation of the data set?

5y(2x-1)=y(x+2)+20, x=3
Answer:
y=1
Step-by-step explanation:
5y(2x-1)=y(x+2)+20, x=3
5y(2(3)-1)=y(3+2)+20
5y(6-1)=y(5)+20
5y(5)=5y+20
25y=5y+20
25y-5y=20
20y=20
y=20/20
y=1
5y(2x-1)=y(x+2)+20, x=3
Step 1: Substitute x with 3
5y(2(3) - 1) = y(3 + 2) + 20
Step 2: Combine like terms in the parentheses
5y(6 - 1) = y(3 + 2) + 20
5y(5) = y(3 + 2) + 20
5y(5) = y(5) + 20
Step 2: Distribute the number outside the parentheses to the numbers inside the parentheses
25y = 5y + 20
Step 3: Combine like terms by subtracting 5y to both sides
25y-5y = (5y-5y) + 20
20y = 20
Step 4: Divide 20 to both sides to isolate y
[tex]\frac{20y}{20} = \frac{20}{20}[/tex]
y = 1
Check:
5(1) (2(3) - 1) = 1(3+2) + 20
5(6-1) = 1(5) + 20
5(5) = 5 + 20
25 = 25
