Harvey has some 1 bills and some 5 in all he has 6 bills worth 22 let x be the number of 1 bills and let y be the number of 5 bills write a system of equations to represent the information and use substitution

Answers

Answer 1
We can write two equations to represent the information given. The first equation represents the total number of bills and the second equation represents the total amount of money:

x + y = 6 (the number of 1 bills plus the number of 5 bills is 6)

1x + 5y = 22 (the total amount of money is 22)

We can use substitution to solve for one of the variables in terms of the other and then substitute that expression back into one of the equations to find the other variable.

From the first equation, we can solve for y in terms of x:

y = 6 - x

Substituting this expression for y into the second equation, we have:

1x + 5(6 - x) = 22

Expanding the right side:

1x + 30 - 5x = 22

Combining like terms:

-4x + 30 = 22

Subtracting 30 from both sides:

-4x = -8

Dividing both sides by -4:

x = 2

So, there are 2 one dollar bills. To find the number of 5 dollar bills, we can substitute x = 2 back into the equation we derived for y:

y = 6 - x = 6 - 2 = 4

So, there are 4 five dollar bills.

Step-by-step explanation:

Shawna joined the bowling league at Bronze Lanes, a bowling alley. She scores a strike 75% of the time. For a perfect game, she needs to bowl a strike 12 times in a row. How likely is it that Shawna will bowl a perfect game at her next game?

Shawna simulates the situation by using a computer to randomly generate 12 numbers from 1 to 4. Each time 1, 2, or 3 appears, it represents a strike

Answers

The probability of Shawna bowling a perfect game is 7.23%.

Assuming that Shawna's chance of getting a strike is independent on each roll (which may not be entirely accurate in real life), the probability of her getting a strike on any given roll is 0.75.

To calculate the probability of Shawna bowling a perfect game (i.e., getting a strike on all 12 rolls), we can use the multiplication rule of probability, which states that the probability of two independent events occurring together is the product of their individual probabilities.

So, the probability of Shawna getting a strike on the first roll is 0.75. The probability of her getting a strike on the second roll, assuming she got a strike on the first roll, is also 0.75. Similarly, the probability of her getting a strike on the third roll, assuming she got strikes on the first two rolls, is also 0.75. We can continue this pattern for all 12 rolls.

Therefore, the probability of Shawna bowling a perfect game is:

0.75 x 0.75 x 0.75 x ... (12 times)

which is approximately equal to 0.0723, or about 7.23%.

Using a computer to randomly generate 12 numbers from 1 to 4 and treating 1, 2, or 3 as a strike is a reasonable way to simulate the situation and estimate the probability of Shawna bowling a perfect game. By repeating this process many times, we can get a better idea of the distribution of possible outcomes and the likelihood of different results.

a fitness club leases space at a major shopping center. the club has 10,500 square feet which represents 16% of the total leasable space at the shopping center. calculate the total leasable space at the center?

Answers

The shopping mall has 65,625 square feet of total leasable area. As stated in the problem, this indicates that the fitness club takes up 16% of the total leasable space.

According to the information provided, a fitness club occupies 10,500 square feet or 16% of the total leasable area at a sizable shopping mall. We can use the proportional and percentage approaches to determine the total leasable area.

Let's assume that the variable "x" stands for the whole amount of leasable space. Since we are aware that the area leased by the gym is 16% of the total leasable area, we can create the following equation:

10,500 = 0.16x

To solve for "x", we can divide both sides of the equation by 0.16:

10,500 / 0.16 = x

Simplifying this expression gives us:

x = 65,625

Therefore, The shopping mall has 65,625 square feet of total leasable area. As stated in the problem, this indicates that the fitness club takes up 16% of the total leasable space.

how many ways can rudy choose 6 pizza toppings from a menu of 14 toppings if each topping can only be chosen once?

Answers

Rudy has 3003 different ways to choose 6 toppings from a menu of 14 toppings if each topping can only be chosen once.

The number of ways to choose 6 toppings from a menu of 14 toppings where each topping can only be chosen once is 14!/(14-6)! = 14!/(8!) = 3003. This is because for the first topping, Rudy has 14 options, for the second topping he has 13 options, for the third topping he has 12 options, and so on. To calculate the total number of combinations, we use the formula n!/(n-r)! where n is the number of items and r is the number of items to choose. This formula gives us the number of ways to choose r items from a set of n items without regard to order, which is the number of combinations.

The formula for combinations is given by n!/(n-r)! where n is the number of items and r is the number of items to choose. Here, n = 14 (the number of toppings on the menu) and r = 6 (the number of toppings Rudy wants to choose). So, the number of combinations is 14!/(14-6)! = 14!/(8!).

The factorial (!) is the product of all positive integers up to that number. For example, 4! = 4 x 3 x 2 x 1 = 24.

So, 14! = 14 x 13 x 12 x ... x 2 x 1 = 87178291199, and 8! = 8 x 7 x 6 x ... x 2 x 1 = 40320.

Now, to calculate the number of combinations, we divide 14! by 8!: 14!/(8!) = 87178291199/40320 = 3003.

Therefore, Rudy has 3003 different ways to choose 6 toppings from a menu of 14 toppings if each topping can only be chosen once.

Answers

Answer:

Step-by-step explanation:Class Trip Fund Calculation

The class figured out that if the percent increase is 99% from the beginning of the year, the class will have enough money for every student to go on the field trip. How much money will the class need to raise for every student to go

To calculate the amount of money that the class needs to raise, you can use the formula for calculating the amount after a percent increase:

amount = original amount + (original amount * percent increase / 100)

Let's assume that the original amount is x. After a 99% increase, the new amount will be:

x + (x * 99 / 100) = x * 199 / 100

So, to find the original amount, you can set up an equation:

x * 199 / 100 = amount needed for the field trip

And then solve for x:

x = amount needed for the field trip * 100 / 199

So, the class needs to raise an amount equal to the amount needed for the field trip * 100 / 199 to have enough money for every student to go on the field trip.

A store charges a restocking fee for any returned item based upon the item price. An item priced at $200 has a fee of $12. An item priced at $150 has a fee of $9. If you return an item that has an original price of $180, how much is the restocking fee?

Answers

An item priced at $200 has a fee of $12. An item priced at $150 has a fee of $9. The restocking fee for an item priced at $180 is $10.

To solve this problem, we need to use a proportion to relate the item price to the restocking fee. The problem provides two pairs of corresponding item prices and restocking fees: $200 and $12, and $150 and $9. We can set up a proportion using these pairs:

$200/$12 = $150/$9

We can simplify this proportion by dividing both sides by 3:

$200/$4 = $150/$3

Now we can use the simplified proportion to find the restocking fee for an item priced at $180. We'll use cross-multiplication:

$200 x $3 = $150 x $4

$600 = $600

This tells us that the ratios are equivalent, and the restocking fee for an item priced at $180 is $10.

In other words, the restocking fee is proportional to the item price, and we can use the given pairs of prices and fees to find the fee for any given price using a proportion.

Answers

Using compounding we know that after 30 years, the account balance has changed by $345.31.

What is continually compounded?

Theoretically, continually compounded interest indicates that interest is continuously earned on an account balance as well as reinvested into the balance so that additional interest is generated.

So, a business owner put $7,000 into a Treasury bond paying a semiannual compound interest rate of 4.3%.

The bond's value after 30 years is $25,084.20.

Instead of compounding twice a year, the investment made by the business owner was made continuously.

After 30 years, we must determine the difference in the account balance.

Think of the continuously compounding recipe:

A = Pe∧rt

We have, p = 7000.

r = 4.3% = 0.043

t = 30

Then,

A = 7000e∧(0.043*30) = 25429..51

A = $25429.51

Therefore, using compounding we know that after 30 years, the account balance has changed by $345.31.

It takes 45 scoops of water.
Since the height and radius of the bucket and the scoop are the same, the volume of the bucket and the scoop can be calculated as follows:

V_bucket = π * r^2 * h = π * r^2 * r = π * r^3
V_scoop = (1/3) * π * r^2 * h = (1/3) * π * r^2 * r = (1/3) * π * r^3

Now that we have the volumes of the bucket and the scoop, we can find the number of scoops it would take to fill the bucket 15 times:

V_bucket * 15 = 15 * π * r^3
V_bucket * 15 / V_scoop = 15 * π * r^3 / (1/3) * π * r^3 = 45

So it would take 45 scoops of water to fill the bucket 15 times.

1) How can we get System BBB from System AAA?

Answers

1. To get System BBB from System AAA, we can divide both sides of the first equation in System AAA by -3:

-3x + 12y = 15

-3x/ -3 + 12y/ -3 = 15/ -3

x + 4y = -5

So System BBB is obtained by dividing both sides of the first equation in System AAA by -3.

2. Are Systems AAA and BBB equivalent?

Yes, Systems AAA and BBB are equivalent. This means that they have the same solution set, despite having different coefficients in their equations. Equivalent systems of linear equations are systems that have the same solution set, regardless of the coefficients of the equations.

two messenger services deliver to a small town. service a has 75% of all the scheduled deliveries, and service b has the remaining 25%. their on-time rates are 80% and 60% respectively. calculate the probability that a package is delivered on time.

Answers

Service a has 75% of all the scheduled deliveries, and service b has the remaining 25%, their on-time rates are 80% and 60% respectively, the probability that a package is delivered on time is 0.75 or 75%.

To calculate the probability that a package is delivered on time, we need to use the law of total probability and the probabilities of on-time delivery for each messenger service.

Let A denote the event that a package is delivered by Service A, and B denote the event that a package is delivered by Service B. Then, we have:

P(on-time delivery) = P(on-time delivery | A) * P(A) + P(on-time delivery | B) * P(B)

where P(on-time delivery | A) is the probability that a package is delivered on time given that it was sent through Service A, and P(A) is the probability that a package is sent through Service A.

Similarly, P(on-time delivery | B) is the probability that a package is delivered on time given that it was sent through Service B, and P(B) is the probability that a package is sent through Service B.

From the information given in the question, we know that P(A) = 0.75, P(B) = 0.25, P(on-time delivery | A) = 0.8, and P(on-time delivery | B) = 0.6. Substituting these values into the above formula, we get:

P(on-time delivery) = 0.8 * 0.75 + 0.6 * 0.25

= 0.6 + 0.15

= 0.75

Intuitively, this result makes sense because Service A, which has a higher on-time rate and delivers 75% of the packages, dominates the total probability of on-time delivery. However, the contribution of Service B cannot be ignored completely and reduces the overall on-time rate slightly.

Answers

Based on your knowledge of the two data sets described below, would you expect a scatter plot describing the two data sets to have a no correlation.

Based on my knowledge, I would not expect there to be a strong correlation between hourly pay and total number of sick days allowed. These two variables are not directly related to each other and there is no clear reason to expect a positive or negative correlation between them. Therefore, I would expect the scatter plot to show no correlation between the two variables. However, it's worth noting that without actually seeing the data, it's difficult to definitively determine whether there is any correlation present.

on january 28, 1986, space shuttle challenger exploded on takeoff. all seven crew members were killed. following the disaster, scientists and statisticians helped analyze what went wrong. they determined that the failure of o-ring joints in the shuttle's booster rockets was to blame. under the cold conditions that day, experts estimated that the probability that an individual o-ring joint would function properly was 0.977. but there were six of these o-ring joints, and all six had to function properly for the shuttle to launch safely. assuming that o-ring joints succeed or fail independently, find the probability that the shuttle would launch safely under similar conditions. show your work.

Answers

The probability of the shuttle launching safely under similar conditions is 0.859, or approximately 86%.

Scientists and statisticians played a crucial role in analyzing the cause of the disaster, which was eventually attributed to the failure of O-ring joints in the shuttle's booster rockets.

To understand the probability of the shuttle launching safely under similar conditions, we need to consider the probability of all six O-ring joints functioning properly. According to experts, the probability of an individual O-ring joint working in cold conditions was 0.977.

Assuming that the O-ring joints succeed or fail independently, we can use the multiplication rule of probability to calculate the probability of all six joints functioning properly.

The multiplication rule states that the probability of two independent events occurring together is the product of their individual probabilities. In this case, the probability of all six joints working properly is:

P(all six joints work) = P(joint 1 works) x P(joint 2 works) x P(joint 3 works) x P(joint 4 works) x P(joint 5 works) x P(joint 6 works)

Plugging in the given probability of an individual O-ring joint working in cold conditions (0.977), we get:

P(all six joints work) = 0.977 x 0.977 x 0.977 x 0.977 x 0.977 x 0.977

P(all six joints work) = 0.977⁶

P(all six joints work) = 0.859

If the two quantities on a coordinate graph are time and distance from home which quantity is a function of which?

Answers

The distance is a function of time and the slope of the distance time graph will give the speed

What is a function rule?

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the first quantity be represented as Distance D

Let the second quantity be represented as Time T

Now , the function is given as

The distance D is a function of time and the slope of the line between the x and y axis of the distance time graph will give us the speed

Substituting the values in the equation , we get

Let the y axis represent the distance D
