One 16-ounce bottle of an energy drink has an average of 500 mg of caffeine with a standard deviation of 25 mg. In a carton containing 30 bottles, what is the standard deviation of the average amount of caffeine?
Final answer:
The standard deviation of the average amount of caffeine in a carton containing 30 bottles of an energy drink is approximately 4.564 mg.
Explanation:
To calculate the standard deviation of the average amount of caffeine in a carton containing 30 bottles of an energy drink, we can use the concept of the sampling distribution of the sample mean.
When independent random samples of a fixed size are taken from a population, the standard deviation of the sample means (σx-bar) is equal to the population standard deviation (σ) divided by the square root of the sample size (n), which is also known as the standard error of the mean.
The formula to find the standard deviation of the sample means is:
σx-bar = σ / √n
In this case, the population standard deviation is given as 25 mg of caffeine, and the sample size is 30 bottles.
So, we calculate the standard deviation of the average amount of caffeine as follows:
σx-bar = 25 mg / √30
σx-bar ≈ 25 mg / 5.477
σx-bar ≈ 4.564 mg (rounded to three decimal places)
Thus, the standard deviation of the average amount of caffeine in a carton containing 30 bottles is approximately 4.564 mg.

The probability of randomly selecting a heart or a spade is 1/2. The probability of randomly selecting a heart or a spade or a club is 3/4. The probability of randomly selecting a two or a diamond is 17/52.
Explanation:(a) There are 13 hearts and 13 spades in a standard deck of cards. The probability of randomly selecting a heart or a spade can be calculated as:
P(Heart or Spade) = P(Heart) + P(Spade) = 13/52 + 13/52 = 26/52 = 1/2
(b) To find the probability of randomly selecting a heart or a spade or a club, we add the probability of selecting a club to the previous result:
P(Heart or Spade or Club) = P(Heart or Spade) + P(Club) = 1/2 + 13/52 = 39/52 = 3/4
(c) There are 4 twos and 13 diamonds in a standard deck of cards. The probability of randomly selecting a two or a diamond can be calculated as:
P(Two or Diamond) = P(Two) + P(Diamond) = 4/52 + 13/52 = 17/52

You buy a pair of jeans at a department store. Jeans 39.99 Discount -10.00 Subtotal 29.99 Sales tax 1.95 Total 31.94 a. What is the percent of discount to the nearest percent? The percent of discount is ___%. b. What is the percent of sales tax to the nearest tenth of a percent? The percent of sales tax is ___% c. The price of the jeans includes a 60% markup. After the discount, what is the percent of markup to the nearest percent? The percent of markup is ___%
The discount offered on the jeans is 25 percent. The sales tax charged on the jeans is 6.5 percent. Markup on the jeans after allowing discount is 60 percent.
a. To find the percent of discount, we need to calculate the actual discount and divide it by the original price, then multiply by 100. From the given information, the original price of the jeans is $39.99 and the discount is $10.00. Therefore, the actual discount is $10.00 and the original price is $39.99. The percent of discount to the nearest percent is:
Percent of discount = (actual discount / original price) x 100
Percent of discount = (10.00 / 39.99) x 100
Percent of discount = 25%
Therefore, the percent of discount to the nearest percent is 25%.
b. To find the percent of sales tax, we need to divide the sales tax by the subtotal, then multiply by 100. From the given information, the subtotal is $29.99 and the sales tax is $1.95. Therefore, the percent of sales tax to the nearest tenth of a percent is:
Percent of sales tax = (sales tax / subtotal) x 100
Percent of sales tax = (1.95 / 29.99) x 100
Percent of sales tax = 6.5%
Therefore, the percent of sales tax to the nearest tenth of a percent is 6.5%.
c. The price of the jeans includes a 60% markup, which means that the selling price is 160% of the cost price. Let x be the cost price of the jeans. Then, the selling price of the jeans is 1.6x. After the discount of $10.00, the selling price becomes 1.6x - 10.00. The percent of markup after the discount to the nearest percent is:
Percent of markup = ((selling price - cost price) / cost price) x 100
Percent of markup = (((1.6x - 10.00) - x) / x) x 100
Percent of markup = (0.6x - 10.00) / x x 100
Percent of markup = 60 - (1000 / x)
Percent of markup = 60%.
So, the percent of markup after the discount is approximately 60%.
When a crew rows with the current, it travels 18 miles in 3 hours. Against the current, the crew rows 6 miles in 3 hours. Let x=the crew's rowing rate in still water and let y = the rate of the current. Find the rate of rowing in still water and the rate of the current.
The speed of the boat in still water is 4mph and the speed of the current is 2mph.
Using the distance formula expressed as:
Distance = speed * time
d = st
Let x be the crew's rowing rate in still water and;
let y be the rate of the current
If a crew rows with the current and it travels 18 miles in 3 hours, the
3(x+y)=18
If they row against the current, the crew rows 6 miles in 3 hours then;
3(x-y)=6
The equations becomes
x + y = 6
x - y = 2
Add both equations
2x = 6 + 2
2x = 8
x = 4
Recall that x + y = 6
4 + y = 6
y = 2
Hence the speed of the boat in still water is 4mph and the speed of the current is 2mph.

How long will it take a $800 investment to be worth $900 if it is continuously compounded at 11% per year?
It takes approximately 1.083 years, or around 1 year and 1 month for an $800 investment to grow to $900 when continuously compounded with an 11% yearly interest rate.
Explanation:To calculate how long it will take for an $800 investment to grow to $900 with continuous compounding at an 11% yearly interest rate, we use the formula for continuously compounded interest, P = Pert, where P is the final amount, Pe is the original principal, r is the interest rate, and t is time in years.
Rearranging the equation to find t, we have, t = ln(P/Pe) / r.
Substitute P as $900, Pe as $800, and r as 0.11 into the formula.
Therefore, t = ln(900/800) / 0.11 = approximately 1.083 years or around 1 year and 1 month.

A parallelogram is cut out of a 12-inch by 8-inch sheet of paper. There are four right triangle remnants. Two have the dimensions 2 inches by 9 inches, and the other two have the dimensions 3 inches by 6 inches. The resulting parallelogram has a base of approximately 9.22 inches. Complete the following steps to calculate the altitude of the parallelogram using area methods. The area of the sheet of paper is square inches. The combined area of the triangle cutouts is square inches. The area of the parallelogram is square inches. The altitude of the parallelogram rounded to two decimals is square inches.
Answer:
96
36
60
6.51
Step-by-step explanation:
The area of a shape is the amount of space it occupies.
The area of the paper is 96 square inchesThe combined area of the triangle cutouts is 36 square inchesThe area of the parallelogram is 60 square inchesThe altitude of the parallelogram is 6.51 inchesThe dimension of the paper is given as: 12-inch by 8-inch
So, its area is:
[tex]\mathbf{A_1 =12 \times 8}[/tex]
[tex]\mathbf{A_1 =96}[/tex]
The dimensions of the 4 right triangles are: Two 2 inches by 9 inches, and two 3 inches by 6 inches
So, the combined area is:
[tex]\mathbf{A_2 = 2 \times \frac 12 \times 2 \times 9 + 2 \times \frac 12 \times 3 \times 6}[/tex]
[tex]\mathbf{A_2 = 36}[/tex]
The area of the parallelogram is the difference between the areas of the paper and the four right triangles.
So, we have:
[tex]\mathbf{A_3 = A_1 - A_2}[/tex]
[tex]\mathbf{A_3 = 96 - 36}[/tex]
[tex]\mathbf{A_3 = 60}[/tex]
The area of a parallelogram is:
[tex]\mathbf{Area = Base \times Altitude}[/tex]
The base is given as 9.22
So, we have:
[tex]\mathbf{60 = 9.22\times Altitude}[/tex]
Divide both sides by 9.22
[tex]\mathbf{6.51 = Altitude}[/tex]
Rewrite as:
[tex]\mathbf{Altitude = 6.51}[/tex]
Hence, the altitude of the parallelogram is 6.51 inches

Allen's monthly take-home pay is $3000, and his monthly rent is $750. If both his monthly take-home pay and his rent increase by $200, what percentage of Allen's take-home pay will be used to pay rent?
Answer:
29.68%
Step-by-step explanation:
Allen's monthly take-home pay is $3000
His monthly rent is $750
Now both his monthly take-home pay and his rent increase by $200
So, After increase Allen's monthly take-home pay =$3000+$200= $3200
After increase His monthly rent = $750+200=$950
Now we are supposed to find what percentage of Allen's take-home pay will be used to pay rent
So, percentage = [tex]\frac{\text{Rent after increase}}{\text {Take- home pay after increase}} \times 100[/tex]
= [tex]\frac{950}{3200}\times 100[/tex]
= [tex]\frac{950}{32}[/tex]
= [tex]29.68\%[/tex]
Hence 29.68% of Allen's take-home pay will be used to pay rent.

To be eligible for a basketball tournament, a basketball team must win at least 60% of its remaining games. If the team has 21 game remaining, how many games must the team win to qualify for the tournament?
The basketball team must win at least 13 out of their 21 remaining games to qualify for the tournament, as they need to win at least 60% of the games.
Explanation:To determine how many games a basketball team must win out of 21 to qualify for a tournament, given they must win at least 60%, we perform the following calculation:
First, multiply the total number of remaining games, which is 21, by 60% (or 0.60) to find the minimum number of games they need to win.Next, solve for the number: 21 games × 0.60 = 12.6.Since a team can't win a fraction of a game, they must win at least the next whole number of games, which is 13.Therefore, the team must win at least 13 games out of the remaining 21 to be eligible for the tournament.
