Answer:

3 is the bottom base 5 for the top base add them together to get 8, height is 3 multiply it by height which is 3 to get 24 divide by 2 since its always used in the formula of a trapezoid, which would be 12

The standard deviation s given z = 3, a desired accuracy of 5%, a mean cycle time of 1.9, a sample size of 17, and (xi+x)2 = 0.1296 is approximately 0.10.

To calculate the standard deviation s, we need to use the formula: s = sqrt((xi+x)2/n-1), where xi is the deviation from the mean, x is the mean, and n is the sample size. First, we need to find xi, which is the square root of 0.1296 divided by n-1, or 0.1296/16 = 0.0081. Next, we find x, which is given as 1.9. Finally, we can use the formula to find s: s = sqrt(0.0081*17) = 0.10 (rounded to two decimal places).

The accuracy of 5% is not directly used in this calculation but is important for determining the confidence level of the standard deviation. The confidence interval is typically expressed as (x-bar ± t(s/√n)), where x-bar is the sample mean, t is the t-distribution value based on the desired confidence level and degrees of freedom, s is the sample standard deviation, and n is the sample size. In this case, we would need to know the desired confidence level and degrees of freedom to calculate the appropriate t-value.

The two planes will meet 6 hours after they start, i.e. at 3 pm.

Two planes leave at 9 am from airports that are 2700 miles apart and fly towards each other at a speed of 200 mph and 250 mph. At what time will they pass each other?

Let's assume the planes A and B leave the two airports that are 2700 miles apart at the same time. The speed of the first plane is 200 mph and the speed of the second plane is 250 mph. To find out the time at which they pass each other, we need to calculate the distance between them and divide it by the sum of their speeds.

Distance traveled by the first plane in time t1 is equal to 200t1.Distance traveled by the second plane in time t2 is equal to 250t2.The distance covered by the first plane and the second plane together will be 2700 miles.Time taken by both the planes to meet can be calculated as below:

t1 + t2 = 2700/(200+250) = 6 hoursAs both the planes start at 9 am, they will meet each other after 6 hours of their journey. Therefore, they will pass each other at 3 pm. This is the required answer. Explanation: So, the two planes will meet 6 hours after they start, i.e. at 3 pm.

The derivative of the function y = xeˣ when calculated is xeˣ + eˣ

Given that

y = xeˣ

To find the derivative of the function y = xeˣ, we can use the product rule and the chain rule of differentiation.

First, we use the product rule:

d/dx = x * d/dx eˣ + d/dx x * eˣ

Next, we use the chain rule to complete the derivative

d/dx = x * eˣ + 1 * eˣ

Substituting this into the product rule equation gives:

d/dx = xeˣ + eˣ

Therefore, the derivative of y = xeˣ is  xeˣ + eˣ

Here is the ans ...hope it helps:)

Part A: Rebecca's credit card balance can be calculated using the equation x = (51 - 1) 0.02 if her finance charge is $51.

Part B: By making the purchase on the final day of the billing cycle rather than the first day, Rebecca will be able to avoid paying $27 in finance charges.

How do equations work?

A mathematical statement proving the equality of values between two or more mathematical expressions is called an equation.

Equation symbols (=) are used to represent equations.

A finance charge is what?

The interest and other fees levied on credit cards are included in a finance charge.

Typically, the finance charge is based on a stated APR (annual percentage rate).

The month's billing cycle lasts for 28 days.

Balance at current starting = x.

APR = 24%, or annual percentage rate.

The monthly percentage rate (MPR) equals 2% (24% divided by 12).

The final day's purchase cost $1,400.

$51 is the total finance fee for the month.

($1,400 x 2% x 1/28) = $1 finance fee for the last-minute purchase.

$50 ($51 - $1) serves as the initial balance's finance charge.

The starting balance at this time is x = $2,500 ($50 x 2%).

Current Beginning Balance Equation: x = 51 - 1 0.02

($1,400 x 2%) Equals $28 in total loan charges for the last-minute purchase.

Finance charge savings from buying on the last day equals $27 ($28 - $1).

By buying the $1,400 gift for her friend on the last day of the billing cycle rather than the first, Rebecca can avoid paying $27 in finance charges.

Answer:

By the end of the week there will be 49,152 zombies in Panama City Beach.

Step-by-step explanation:

Since the Zombie Apocalypse has come to Panama City Beach, starting when 3 Spring Breakers become zombie after an encounter with a deadly fish, and since waking up the next day, each Spring Breaker can infect 4 more people per day before needing a rest , and each of these zombies can, in turn, infect an additional 4 people per day, to determine how many crazy Spring Break Zombies will be roaming the beach at the end of the week the following exponential function has to be solved:

3 x 4 ^ 7 = X

3 x 16,384 = X

49.152 = X

Therefore, by the end of the week there will be 49,152 zombies in Panama City Beach.

The number of crazy Spring Break Zombies will be roaming the beach at the end of the week 7 are 49,152 and the equation for the situation is,

\(x=3\times(4)^7\\\)

Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.

The exponential function with dependent variable y and independent variable x can be written as,

\(y=ba^x+c\)

Here, a, b and c are the real numbers.

The Zombie Apocalypse has come to Panama City Beach. It starts when 3 Spring Breakers become zombie after an encounter with a deadly fish.

In the next morning, each Spring Breaker can infect 4 more people per day before needing a rest. Each of these zombies can, in turn, infect an additional 4 people per day.

As total number of weeks are 7. Thus, for this situation, the exponential function for the variable x can be given as,

\(x=3\times(4)^7\\\)

Now to find the number of crazy Spring Break Zombies will be roaming the beach at the end of the week 7, simplify the above equation as,

\(x=3\times(4)^7\\\\x=3\times16384\\x=49152\)

Hence, the number of crazy Spring Break Zombies will be roaming the beach at the end of the week 7 are 49,152 and the equation for the situation is,

\(x=3\times(4)^7\\\)

Answer: 12

Step-by-step explanation:

Answer:

B.   3,158

Step-by-step explanation:

h(x) = -49x − 125

Let x = -67

h(-67) = -49(-67) − 125

          =3283-125

          = 3158

Answer:

Answer B

Step-by-step explanation:

To find the value of h(-67) for the function h(x) = -49x - 125,

we substitute -67 for x in the function and evaluate it.

h ( - 67 ) = - 49 ( - 67 ) - 125

Now we can simplify the expression:

h ( -67 ) = 3283 - 125

h ( -67 ) = 3158

Since each canoe sells for $800 and has a variable unit expense of $400, the contribution margin per canoe is $400 ($800 selling price - $400 variable unit expense).
Using the contribution margin per canoe, we can calculate the number of canoes Tippy Canoe needs to sell to reach a revenue of $200,000:
$200,000 / $400 contribution margin per canoe = 500 canoes
Therefore, Tippy Canoe needs to sell 500 canoes to make a $150,000 profit.

To calculate the number of canoes Tippy Canoe needs to sell to make a $150,000 profit, we'll use the formula: Profit = (Selling Price - Variable Expense) × Number of Canoes - Fixed Expenses.

Since each canoe sells for $800 and has a variable unit expense of $400, the contribution margin per canoe is $400 ($800 selling price - $400 variable unit expense).
Using the contribution margin per canoe, we can calculate the number of canoes Tippy Canoe needs to sell to reach a revenue of $200,000:
Let's denote the number of canoes as "x." We want to find x in this equation:
$150,000 = ($800 - $400) × x - $50,000.

First, simplify the equation:
$150,000 = $400x - $50,000.

Now, add $50,000 to both sides of the equation:
$200,000 = $400x.

Finally, Using the contribution margin per canoe, we can calculate the number of canoes Tippy Canoe needs to sell to reach a revenue of $200,000:
And, divide both sides by $400 to find the value of x:
x = 500.
Tippy Canoe needs to sell 500 canoes to make a $150,000 profit.

The correct answer is option a. $7,594.46.

To calculate the amount you would reduce the amount you owe in the first year, we can use the formula for the equal installment of a loan. The formula is:

Installment = Principal / Number of Installments + (Principal - Total Repaid) * Interest Rate

In this case, the principal is $45,000, the number of installments is 5, and the interest rate is 8.5%.

Let's calculate the amount you would reduce the amount you owe in the first year:

Installment = $45,000 / 5 + ($45,000 - $0) * 0.085Installment = $9,000 + $3,825

Installment = $12,825

Therefore, you would reduce the amount you owe by $12,825 in the first year.The correct answer is option a. $7,594.46.
