Jeriel would need to invest approximately $98,986.25 for the value of the account to reach $137,000 in 5 years, assuming continuous compounding.

The formula accrued amount compounded continuously is expressed as;

A = P × e^(rt)

Where A is accrued amount, P is principal, r is interest rate and t is time.

In this case, we are given that the final amount to be $137,000, the interest rate is 6.5% and the time is 5 years.

We want to solve for Principal P.

First, convert R as a percent to r as a decimal

r = R/100

r = 6.5/100

r = 0.065 per year

Plug these values into the above formula and solve for P.

A = P × e^(rt)

P = A / e^(rt)

P = 137,000.00 / e^(0.065 × 5)

p = $98,986.25

Therefore, the value of the principal P is $98,986.25.

The total cost of the laptop with the sales tax included is 938.18.

The total cost of the laptop with the sales tax included is the sum of the original price and the tax amount. The formula to calculate the total cost is given below:

Total Cost = Original Price + (Original Price * Sales Tax Rate)

In this case, the Original Price is 882.99 and the Sales Tax Rate is 6.25%. Therefore, the Total Cost of the laptop with the sales tax included is calculated as follows:

Total Cost = 882.99 + (882.99 * 0.0625)

Total Cost = 882.99 + 55.19

Total Cost = 938.18

Rounding to the nearest cent, the total cost of the laptop with the sales tax included is 938.18.

The relationship between t, the number of tickets, and c, the total cost of tickets is: c = 55t

Relation between two variables, i.e, total cost and number of tickets:

The statistical relationship between two variables is called their correlation. The correlation can be positive, which means that the two variables move in the same direction, or negative, which means that when the value of one variable increases, the value of the other variable decreases.

Based n the Question:

Since there is no processing fee and the ticket price remains the same, we know that the fee will be proportional to the number of tickets purchased. The general form of the equation expressing the proportional relationship between the cost (c) and the number of tickets (t) is:

c = kt

where k is the constant of proportionality (the cost per ticket).

We can find k by using any of the data points given in the table. Using the first point, we have :

110 = k·2

Dividing the equation by 2:

110/2 = k = 55

Then using this value for k, the desired equation can be written:

c = 55t

The correct option B. The expression for the inverse is f¹(x) = (x - 7)².

A one-to-one function is given. We have to write an expression for the inverse function.

Given function: f(x)=√x+7

The inverse of a function is found by switching the x and y coordinates and solving for y.

So, the expression for the inverse function will be:

f¹(x) = y = √x + 7 ... (1)

Replace x with y and simplify to isolate y from the radical.

   y = √x + 7

=> y - 7 = √x

=> (y - 7)² = x

Hence, the inverse of the given function is given byf¹(x) = (x - 7)².

For the rectangle, the value x will be 14 and angle UDK will be 35°.

What exactly is a rectangle?

A rectangle is a four-sided polygon with four right angles (90-degree angles). It has opposite sides that are equal in length and parallel to each other. The rectangle is a special case of a parallelogram, where the opposite sides are also parallel. The two sides that are equal in length are called the "width" or "short side", while the other two sides are called the "length" or "long side". The area of a rectangle is found by multiplying its length by its width, while its perimeter is found by adding the lengths of all four sides.

Now,

As we know all angles of a triangle are 90°.

then 5x-15+2x+7=90

7x=98

x=14

and in triangle UDK

sum of all angles = 180°

∠UDK+90+5x-15=180

This formula generates the sequence 0, -1/2, 2/3, -3/4, 4/5, -5/6, 6/7, ...

Notice that the sequence alternates between positive and negative terms and that the denominators of each term increase by 1 while the numerators increase by 1 or -1. To find the explicit formula, we can write it in terms of its general form:

a1 = 0

a2 = -1/2

a3 = 2/3

a4 = -3/4

a5 = 4/5

a6 = -5/6

a7 = 6/7

We can see that the numerator of each term is equal to its index number, n, if n is even and equal to -n if n is odd. The denominator of each term is equal to n+1 for all terms.

Using this observation, we can write the explicit formula for the sequence as:

an = (-1)^(n+1) * n / (n+1)

where (-1)^(n+1) is equal to -1 if n is odd and 1 if n is even. This formula generates the sequence 0, -1/2, 2/3, -3/4, 4/5, -5/6, 6/7, ...

The coffee distributor should mix 8 pounds of Kenya coffee blend and 2 pounds of breakfast coffee blend to make 10 pounds of a coffee blend that can sell for $9.36 per pound.

We can use the idea of weighted averages to overcome this issue. Assume that 10 pounds of the desired blend require x pounds of Kenya coffee blend and y pounds of morning coffee blend.

The price of the Kenya coffee mix per pound is $8.20, while the price of the morning coffee blend per pound is $14.00. The required combination costs $9.36 per pound. On the basis of the weighted average, we can construct the following equation:

8.20x + 14.00y = 9.36(10) (10)

When we simplify this equation, we obtain:

8.20x + 14.00y = 93.60

Given that we are producing 10 pounds of the ideal blend, we also know that x + y = 10. To get the values of x and y, we can use substitution or elimination to solve this system of equations.

Use substitute now. We can find x from the second equation by solving in terms of y:

x = 10 - y

Substitute this into first equation, we get:

8.20(10 - y) + 14.00y = 93.60

82 - 8.20y + 14.00y = 93.60

5.80y = 11.60

y = 2

We obtain x = 8 by substituting y = 2 into x = 10 - y. Hence, to manufacture 10 pounds of a coffee mix that can be sold for $9.36 per pound, we'll need 8 pounds of Kenya coffee blend and 2 pounds of breakfast coffee blend.

Step-by-step explanation:

The probability that the 15 cards contain exactly one queen given that they contain exactly two aces is approximately 0.060 or 6.0%.

We can use conditional probability. Let A be the event that the 15 cards contain exactly two aces, and B be the event that they contain exactly one queen. Then we want to find the conditional probability P(B|A).

First, let's find the probability of A. There are C(4,2) ways to choose the two aces out of four, and C(48,13) ways to choose the other 13 cards out of the remaining 48 cards. So the total number of ways to choose 15 cards with exactly two aces is:

C(4,2) × C(48,13) ≈ 4.57 × 10^12

Next, let's find the probability of both A and B. There are C(4,2) ways to choose the two aces out of four, C(4,1) ways to choose one queen out of four, and C(47,12) ways to choose the other 12 cards out of the remaining 47 cards. So the total number of ways to choose 15 cards with exactly one queen and exactly two aces is:

C(4,2) × C(4,1) × C(47,12) ≈ 2.76 × 10^11

Finally, we can use the formula for conditional probability:

P(B|A) = P(A and B) / P(A)

P(B|A) = (C(4,2) × C(4,1) × C(47,12)) / (C(4,2) × C(48,13))

P(B|A) ≈ 0.060

Therefore, the probability is approximately 0.060 or 6.0%.

As per the expression, the cost of 444 burgers and 666 hot dogs from Eric's Hot Ham food truck would be $2773.

In this case, Eric's expression is 3.25b + 2h, where b represents the number of burgers and h represents the number of hot dogs. The expression tells us how much it costs to buy a certain number of burgers and hot dogs from Eric's truck.

To find the cost of 444 burgers and 666 hot dogs, we can substitute b = 444 and h = 666 into the expression. So the cost would be:

3.25(444) + 2(666)

Now we just need to simplify this expression by using the order of operations.

First, we multiply 3.25 by 444 to get 1441. Then, we multiply 2 by 666 to get 1332.

Suppose that IQ scores have a bell-shaped distribution with a mean of 96 and a standard deviation of 17. Using the empirical rule, 15.87 percentage of IQ scores are less than 79.

The empirical rule says that for a normal distribution, almost all of the data will fall within three standard deviations of the mean.

Specifically:
Approximately 68% of the data falls within one standard deviation of the mean.
Approximately 95% of the data falls within two standard deviations of the mean.
Almost all (99.7%) of the data falls within three standard deviations of the mean.
Given that the mean of IQ scores is 96 and the standard deviation is 17.

Hence the Z score can be calculated as
z=(x−μ)/σ=(79−96)/17=−1
From the standard normal distribution table, the percentage of the data that is less than z = -1 is 15.87%.
Hence the percentage of IQ scores that are less than 79 is approximately 15.87%.
