Write an integer to represent a 6 yard loss in football.
Answer: - 6.
Step-by-step explanation:
The set of integers is the set of the whole numbers. {..., -1, 0, 1, 2, ...}
We want to represent a loss by 6 yards in football.
Because this is a loss, we should use a negative number, then we can use:
-6
This represents the number of yards by which your team losts.
Notice that I did not write the units, this is because:
-6 yards is a measure, furthermore can be "an integer number of yards"

You need a 55% alcohol solution. On hand, you have a 550 mL of a 95% alcohol mixture. How much pure water will you need to add to obtain the desired solution?
Answer:
We need to add 400 ml of pure water to obtain the solution at 55%
Step-by-step explanation:
Concentration
The concentration of a solution measures the amount of solute that has been dissolved in a given amount of solution. The question states the alcohol is the solute and water is the solvent to produce the mix or solution.
The concentration can be calculated with the formula:
[tex]\displaystyle c=\frac{solute}{solute+solvent}*100\%[/tex]
Originally, the mixture was 95% concentrated.
Substituting in the formula:
[tex]\displaystyle 95\%=\frac{solute}{solute+solvent}*100\%[/tex]
We know there were 550 ml of solution (solute+solvent), thus
[tex]solution*0.95=solute=522.5\ ml[/tex]
Now we know there were 522.5 ml of alcohol.
We now need to add x ml of water to have a 55% concentrated solution. Recall that water is solvent, the solute keeps its original value, thus:
[tex]\displaystyle 55\%=\frac{solute}{550+x}*100\%[/tex]
Operating:
[tex]0.55(550+x)=522.5[/tex]
Dividing by 0.55
[tex]550+x=950[/tex]
Thus [tex]x=950-550=400[/tex]
We need to add 400 ml of pure water to obtain the solution at 55%
find the percent change from 50 to 22
Answer:
28
Step-by-step explanation:
50 - 22 = 28
Answer:
56% decrease or -56.00%
Step-by-step explanation:
1) Find the difference between 50 and 22 as a number.
2) Divide the result from Step 1 by the starting number 50.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 50 to 22, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 50, and Y is the ending number 22 that it changed to When we enter these numbers into the formula, we get:
((22-50)/50)*100 = -56.00%

6) A boat traveled 80 miles downstream and back. The trip downstream took 5 hours. The trip back took
10 hours. What is the speed of the boat in still water? What is the speed of the current?
Answer:
12 mph and 4 mphStep-by-step explanation:
Let the speed of the boat = b and the speed of the current = cEquations to reflect time, time = distance/speed:
Downstream80/(b + c)= 5 ⇒ b - c = 80/5 ⇒ b + c = 16Upstream80/(b - c) = 10 ⇒ b - c = 80/10 ⇒ b - c = 8Sum of the 2 equations above
b + c + b - c = 16 + 82b = 24b = 12c = 16 - 12 = 4So the speed of the boat is 12 mph
The speed of the current is 4 mph

C≈18.85 cm
A≈28.27 [tex]cm^{2}[/tex]
The area of the circle is approximately 28.27 cm², and the circumference is approximately 18.85 cm.
We have,
Area of a circle: A = πr²
Circumference of a circle: C = 2πr
Radius (r) = Diameter / 2 = 6 cm / 2 = 3 cm
Area of the circle:
A = πr² = π(3 cm)² ≈ 28.27 cm²
Circumference of the circle:
C = 2πr = 2π(3 cm) ≈ 18.85 cm
Therefore,
The area of the circle is approximately 28.27 cm², and the circumference is approximately 18.85 cm.

Step-by-step explanation:
Use a calculator to see what would happen if you used a credit card to pay the minimum monthly payment. Calculate using the following information: Cost of computer (balance): $600 Annual percentage rate (APR): 12.9% Total duration of payments: 2 years Use the simple interest formula: A = (P)(r)(t) If you make only the minimum payment each month, what will the total cost of the computer be?
Answer:
C. $755 i got it right
Step-by-step explanation:
If you make only the minimum payment each month, the total cost of the computer will be $755.00, which is $155 more than the original cost of the computer ($600).
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To calculate the total cost of the computer if you make only the minimum payment each month, we need to use the simple interest formula:
A = P(1 + rt)
where A is the total amount paid, P is the principal or balance, r is the annual interest rate expressed as a decimal, and t is the time in years.
P = $600
r = 12.9% or 0.129 (annual interest rate)
t = 2 years
To find the monthly interest rate, we divide the annual interest rate by 12 (the number of months in a year):
Monthly interest rate = 0.129 / 12 = 0.01075
Now, we can use this monthly interest rate to calculate the minimum monthly payment:
Minimum monthly payment = 1% x P = 0.01 x $600 = $6
Therefore, the minimum monthly payment is $6.
To find the total cost of the computer over the 2-year period, we need to calculate the total amount paid (A) by making the minimum monthly payment each month:
A = P(1 + rt)
A = $600(1 + 0.01075 x 2 x 12)
A = $600(1 + 0.258)
A = $755.00
Therefore, if you make only the minimum payment each month, the total cost of the computer will be $755.00, which is $155 more than the original cost of the computer ($600).

You need to arrange 10 of your favorite books on a small shelf. How many different ways can you arrange the books, assyming that the ordwr of the books make a differe
Answer:
You can arrange the books 3,628,800 different ways.
Step-by-step explanation:
You can imagine that the shelf has 10 "slots" where you can place a book. Each slot can take 1 of the 10 books. However, after you have placed 1 book, there are only 9 possible books to place. After 2 have been placed, there are only 8 possible.
Going left-to-right, the first slot has 10 available books.
Total combinations: 10
The 2nd slot has 9 available books.
Total combinations: 10 * 9
The 3rd slot has 8 available books.
Total combinations: 10 * 9 * 8
This continues for all 10 slots.
Eventually, for slot 10, there is only 1 book possible.
Total combinations: 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
Multiply all numbers between 10 and 1 with each other is also known as "10 factorial" or "10!"
Thus, the total number of combinations is:
[tex]10! = 10*9*8*7*6*5*4*3*2*1 = 3628800[/tex]
Answer: You can arrange the books 3,628,800 different ways.
Suppose you are interested in how participants behave in different color conditions. You select 30 participants and assign them to one of three rooms. The rooms differ only with respect to the color of the walls. One room is white, one is pale blue, and a third is bright red. Each participant is served a meal of a hamburger and french fries, and you then measure how long it takes them to finish eating. What would be the independent variable in this study
The answer is the color of the room
Explanation:
In this study, the color of the room is the factor or variable that is modified by the researcher. Also, it is expected the color of the room affects participants' behavior but not the opposite. This shows the color of the room is an independent variable because this factor is not affected by other variables, and it modifies the dependent variable (behavior). Moreover, in studies, the independent variable is always the one that is changed by the researcher.
A polling organization asked a nation-wide random sample of 1600 new brides (those who got married in the past 2 years) the following question: "How much money did your wedding cost?"

Correct: It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively. Incorrect It has millions of tickets. The average of the tickets is exactly $20,000 and the SD is exactly $5,000. Incorrect It has millions of tickets marked with "0"s and "1"s, but the exact percentage of each is unknown.
Answer:
It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.
Step-by-step explanation:
Given that:
sample size n = 1600
sample mean [tex]\overline x[/tex] = 20000
standard deviation = 5000
The objective is to choose from the given option about what most closely resembles the relevant box model.
The correct answer is:
It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.
However, if draws are made without replacement, the best estimate of the average amount for the bride will be $20,000
Similarly, the standard error for the sample mean = [tex]\dfrac{s}{\sqrt{n}}[/tex]
[tex]= \dfrac{5000}{\sqrt{1600}}[/tex]
[tex]= \dfrac{5000}{40}}[/tex]
