Step-by-step explanation:
Hi there,
We know that a pair means two and so for each pair of socks he has, we are going to multiply that number by two to find the individual amount.
White socks: 2 pairs x 2 = 4 total white socks
Black socks: 4 pairs x 2 = 8 total black socks
Blue socks: 1 pair x 2 = 2 total blue socks.
Now, you add up the total amount of individual socks in the drawer.
4+8+2 = 14 socks.
We are trying the find the probability that he is going to pick a black sock. The amount of black socks is going to go on the numerator of the fraction and the total amount of socks in the drawer is going to go on the denominator.
8 black socks / 14 total socks
Now that we have this fraction, we need to simplify it. The number 8 and 14 are both divisible by 2, so we now have the fraction (4/7).
What this means is that, theoretically, if he randomly pulled out 7 socks, that 4 of the socks he pulls out should be black, leaving the probability he picks out black socks to be (4/7) of the time or about 57% likely to happen.
I hope this helps, let me know if you have questions :)

So basically you use this formula to find the best-guessed height and length of the rectangular prism.
1029/7√=
147√=
12.12436
So the best-guessed height and length were both 12.12436.
Now take this info you learned from calculating the best-guessed height and length of the left prism. We are now going to use 12.12436 as the height and length for the right prism. Now make sure to use the order of operations rule "PEMDAS" to solve this equation. If you don't you will get the wrong answer.
12.12436(8)²=
147(8)=
1176
So the best-guessed volume of the right prism is 1176.
Part B:So basically what you have to do is divide 1029 by the solution of height×width which will give you your length.
1029/(14×7)=
1029/98=
10.5
So the best-guessed length of the left prism is 10.5.
Now you will use this info to solve your problem
14×8×10.5= 1,008
1008/8√=
126√=
11.22497
So the best-guessed height would be 11.22497.

Find the best measure of variability for the data and determine which player was more consistent.
Player A is the most consistent, with a range of 7.
Player B is the most consistent, with a range of 9.
Player A is the most consistent, with an IQR of 2.5.
Player B is the most consistent, with an IQR of 3.5.
Answers
To find the best measure of variability for the data and determine which player was more consistent, we can calculate the range and the interquartile range (IQR) for both players.
The range is calculated by subtracting the minimum value from the maximum value in a dataset. The IQR is a measure of dispersion that represents the range between the first quartile (Q1) and the third quartile (Q3) in a dataset.
Let's calculate the range and IQR for both players:
For Player A:
The data for Player A is: 2, 1, 3, 8, 2, 3, 4, 4, 1.
To calculate the range:
[tex]\text{Range} = \text{maximum value} - \text{minimum value}[/tex]
The maximum value is 8, and the minimum value is 1.
[tex]\text{Range} = 8 - 1 = 7[/tex]
For Player B:
The data for Player B is: 1, 4, 5, 1, 2, 4, 5, 5, 10.
To calculate the range:
[tex]\text{Range} = \text{maximum value} - \text{minimum value}[/tex]
The maximum value is 10, and the minimum value is 1.
[tex]\text{Range} = 10 - 1 = 9[/tex]
To calculate the IQR, we need to find the first quartile (Q1) and the third quartile (Q3) for each player:
For Player A:
Arranging the data in ascending order: 1, 1, 2, 2, 3, 3, 4, 4, 8.
To calculate Q1, we find the median of the lower half of the data: 1, 1, 2, 2, 3.
Q1 = 2
To calculate Q3, we find the median of the upper half of the data: 3, 4, 4, 8.
Q3 = 4
The IQR is calculated as:
[tex]\text{IQR} = Q3 - Q1[/tex]
[tex]\text{IQR} = 4 - 2 = 2[/tex]
For Player B:
Arranging the data in ascending order: 1, 1, 2, 4, 5, 5, 5, 10.
To calculate Q1, we find the median of the lower half of the data: 1, 1, 2, 4.
Q1 = 1.5
To calculate Q3, we find the median of the upper half of the data: 5, 5, 5, 10.
Q3 = 5
The IQR is calculated as:
[tex]\text{IQR} = Q3 - Q1[/tex]
[tex]\text{IQR} = 5 - 1.5 = 3.5[/tex]
Based on the calculations, we can conclude:
Player A is the most consistent, with a range of 7.
Player B is the most consistent, with a range of 9.
Player A is the most consistent, with an IQR of 2.
Player B is the most consistent, with an IQR of 3.5.
Therefore, the correct answer is:
Player A is the most consistent, with an IQR of 2.

Indiana plans to purchase a new gaming system during the 15% off sale. Let c represent the cost of the gaming system. How can you write a function to represent this?

Write one single function to help Indiana know how to calculate the final cost.
Answers
Answer:
The single function to calculate the final cost of the gaming system, including a 15% off discount and a 10% state tax, is: final_cost(c) = 0.935c.
Step-by-step explanation:
To represent the cost of the gaming system before any discounts or taxes, we can use the variable c:
c represents the cost of the gaming system.
To represent the price after the 15% off discount, we need to calculate the discounted price by subtracting 15% of the cost from the original cost:
p = c - 0.15c
Simplifying, we get:
p = 0.85c
Here, p represents the price after the 15% discount has been applied.
To represent the price after the 10% state tax has been added to the discounted price, we need to calculate the price with the added tax:
final_price = p + 0.1p
Simplifying, we get:
final_price = 1.1p
Here, final_price represents the price after the 10% state tax has been added.
Therefore, the correct single function to help Indiana calculate the final cost is:
final_cost(c) = 1.1(0.85c)
Simplifying further:
final_cost(c) = 0.935c

Sure.
Tom and Juanita are moving in opposite directions, so their speeds are added together. Their combined speed is 16+18=34 mph.
If they travel for 2 hours at a speed of 34 mph, they will travel a distance of 34×2=68 miles.

How far did I travel to reach my destination on each day of my three-day Trip?

b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
Answers
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
