Use the simple interest formula to determine the missing value.
p = ? r = 6% t = 3 months i= 21$

Answers

Answer 1

Answer:

p = 1,400

Step-by-step explanation:

Simple Interest Formula:

In the simple interest rate formula, each year the same amount of interest is applied, as it's based off the initial amount invested and the interest rate.

[tex]I=P*r*t[/tex]

Where "r" is the interest rate, "t" is time, and "p" is the principle amount, or initial amount invested.

We're given the following values:

r = 6% = 0.06t = 3 monthsi = 21

Now the only thing is generally speaking, interest is applied annually rather than monthly. So we would need to convert the 3 months into years, which we can do by dividing by 12, giving us: 0.25 years

So we actually have: t = 0.25 years

Now from here we can plug in known values, and leave anything we don't know alone. So we start with our initial formula of:

[tex]I=P*r*t[/tex]

Now from here we plug in i = 21, t = 0.25, r = 0.06 and leave "P" as "P"

[tex]21=P*0.25*0.06[/tex]

Now let's simplify the multiplication on the right side:

[tex]21 = 0.015P[/tex]

Divide both sides by 0.015:

[tex]1,400=P[/tex]

And now we have our missing value!

show that the additive inverse, or negative, of an even number is an even number using a direct proof.

Answers

Let x be an even number. Then, x = 2k for some integer k. The negative of x, -x, is equal to -2k, which is also an even number. Thus, the additive inverse of an even number is an even number.

An even number is any number that can be divided by 2 without any remainder, meaning that it can be written in the form x = 2k for some integer k. The additive inverse, or negative, of an even number, x, is -x. By definition, this is equal to -2k. As -2k can still be divided by 2 without any remainder, it is also an even number.

This can also be understood by looking at the positive and negative sides of the number line. If x is an even number, then it is two units away from 0. Therefore, -x is also two units away from 0, which means it is an even number. This shows that the additive inverse of an even number is an even number.

To prove this, we can look at a specific example. Let x = 8. Then, 8 = 2x4. The negative of 8, -8, is equal to -2x4, which is still an even number. Thus, this proves that the additive inverse of an even number is an even number.

The median of a data set is the middle value when the data is arranged in ascending or descending order. When number of values is even, there are two values in the middle, so we take the average of the two. So the median is

= (26 + 27)/ 2

= 26.5

The first quarter or the lower quartile (Q1), is the value under which 25%, that is first quarter of the data points are found when they are arranged in increasing order. Here Q1 is  0.25*10,  that is 2.5th value, but its not possible. So we should interpolate

Q1 = 22.5

Similarly third quartile, Q3 is the value under which 75% of the data points are found when they are arranged in increasing order. So

Q3 = (70 + 50)/2

= 60

A. $2,205.90
C. $6,490.00
B. $2,329.80
D. $2,400.50

Answers

Answer:

Step-by-step explanation:

The balance after 3 years can be calculated as follows:

I = P * r * t

Where:

I = interest

P = principal amount (2200)

r = interest rate (0.0295)

t = time in years (3)

So,

I = 2200 * 0.0295 * 3

I = 153.1

The final balance would be:

P + I = 2200 + 153.1

P + I = 2353.1

The final balance after 3 years is $2353.1, which is closest to option B ($2,329.80).

find the other end point of the line segment with the given endpoint and midpoint endpoint: (6.9), midpoint (,-6)

Answers

The other endpoint of the line segment is (13.8, 6).

The midpoint of a line segment is the point that lies exactly halfway between the two endpoints.

In this case, we have one endpoint, (6.9), and the midpoint (0,-6). Here is how we find the other endpoint:

To find the other endpoint, we need to subtract the midpoint from the given endpoint and then multiply by 2. The midpoint formula is given by:

M = (x1 + x2) / 2 and (y1 + y2) / 2

Where M is the midpoint, (x1, y1) and (x2, y2) are the coordinates of the two endpoints.

So, in our case, the other endpoint will be given by:

(x2, y2) = 2 * (6.9, 0) - (0, -6)

Expanding the expression, we get:

x2 = 2 * 6.9 - 0 = 13.8

y2 = 2 * 0 - (-6) = 6

Therefore, the other endpoint of the line segment is (13.8, 6).

1. A soft-drink manufacturer can produce 1000 case of soda in a week at a total cost of GHC6,000, and 1,500 cases of soda at a cost of GHe8,500. Fid the manufacturer's weekly fixed costs and marginal cost per case of soda.​

Answers

To find the manufacturer's weekly fixed costs and marginal cost per case of soda, we can use the following equations:

Total Cost = Fixed Cost + Variable Cost

Variable Cost = Marginal Cost * Quantity

At 1000 cases of soda, the variable cost is GHC6,000, and the total cost is GHC6,000. So the fixed cost at this quantity can be found as:

Fixed Cost = Total Cost - Variable Cost
Fixed Cost = GHC6,000 - (1000 * GHC6/1000) = GHC6,000 - GHC6 = GHC0

This means the manufacturer has no fixed costs at this quantity of 1000 cases.

Next, we can find the marginal cost per case of soda by calculating the change in the variable cost as the quantity changes from 1000 to 1500 cases.

Variable Cost = Total Cost - Fixed Cost
Variable Cost = GHC8,500 - GHC0 = GHC8,500

Marginal Cost = (Variable Cost at 1500 cases - Variable Cost at 1000 cases) / (1500 - 1000)
Marginal Cost = (GHC8,500 - GHC6,000) / 500 = (GHC2,500) / 500 = GHC5

So the manufacturer's marginal cost per case of soda is GHC5.

Note: The fixed cost is assumed to be zero because the information provided does not specify any fixed costs. This may not necessarily be the case in a real-world scenario.

What is the sum of the first 45 terms of an arithmetic sequence if the sum of its 18 th and 28 th term is 36?

Answers


The simplest arithmetic progression satisfying the given condition is the constant progression with all 45 terms equal to 18. The sum of that progression is 45×18=810. If we assume there's enough information to deduce the answer, that must be it.

The reason the sum of the 18th
and 28th terms are enough to determine the sum is the symmetric placement of those two terms about the center of the progression.

The sum of 45 terms of the arithmetic progression whose sum of 18 th and 28 th terms is 36 is given by 810.

Let the first term of the arithmetic progression be A and the common difference for the same be D.

So 18th term of the progression is = A + (18 - 1) D = A + 17D

28th term of the progression is = A + (28 - 1) D = A + 27D

Given that the sum of the 18th and 18th terms of the progression is 36.

So, A + 17D + A + 27D = 36

2A + 44D = 26

So now the sum of 45 terms of the arithmetic progression is given by,

= 45/2 [2A + (45 - 1)D]

= 45/2 [2A + 44D]

= (45/2) * 36

= 45 * 18

= 810

Hence the sum of 45 terms of the arithmetic progression whose sum of 18 th and 28 th terms is 36 is given by 810.

(e) E(Y) = 125, Var(Y) = 4.5

Answers

The correct option is (b) as the expected value and variance of daily revenue are 37.5 and 4.5 respectively.

What is meant by variance?

Consider the expected value to be the average value. The expected value of X when it is a discrete random variable is the exact mean of the relevant data.

The difference between the actual numbers and the average should be viewed as the variance. A greater range of values is indicated by a higher variance. A spread of measure for a random variable distribution that quantifies how much a random variable's values deviate from its expected value is called variance. Frequently, V(X) is used to represent the variance of random variable X.

Given,

  Cost of soft drink c = $0.30

   Expected value of the number of cans sold per day E(X) = 125

  Variance of number of cans sold per day V(X) = 50

 So,

    Expected value of daily revenue E(Y) = c *  E(X) = 0.3 * 125 = 37.5

  Variance of daily revenue V(Y) = * V(X) = 0.3² * 50 = 4.5

Therefore the expected value and variance of daily revenue are 37.5 and 4.5 respectively. The correct option is (b).

Consider the function below. x= -1, 0,1,2 and f(x)= -2,3,8,13 Which of the following functions could be the inverse of function f?

Answers

Answer:

Step-by-step explanation:

A function is the inverse of another function if it "undoes" the original function. In other words, if you apply the original function to an input and then apply the inverse function to the result, you get the original input.

To find the inverse of a function, you can swap the input and output values of the original function, and then solve for the new input variable. For example, if the original function is f(x) = y, the inverse function would be f^-1(y) = x.

Given the function f(x) = -2, 3, 8, 13, it is not possible to find a simple algebraic inverse function for the given values of x = -1, 0, 1, 2. The inverse of a function is only well-defined if the function is one-to-one, meaning that for every output value, there is only one input value that maps to it. In this case, the function does not appear to be one-to-one, so it does not have an inverse function.

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.

Since the pizza was heated at a constant rate, we can model the experiment as a line, where the slope represents how fast the pizza was heated.

The slope is given as:

m = (y2 - y1)/(x2 - x1)

Let

(x1,y1) = (6, 40)

(x2,y2) = (8, 55)

m = (55 - 40) / ( 8 - 6 )

m = 7.5 degrees per minute.

The pizza heats up an average of 7.50 degrees per minute

To reach a temperature of 100 degrees the pizza would take:

(100)(7.50) = 750 minutes.

Hence, to reach a temperature of 100 degrees the pizza would take:

(100)(7.50) = 750 minutes.

the heights of a group of students, in centimeters, are 158, 162, 172,.157, 161.com. A) caculate the mean heaight . B) another student joins the group. his height is 169cm. calculate the new mean height?​

Answers

Step-by-step explanation:

So basically To find the mean you have to add all the numbers and divide by how many numbers you have, but to do that you have to make sure the numbers are lined up correctly so

157,158,161,162,172 ( Correct Order ) Smallest to biggest now add these up

157 + 158 + 161 + 162 + 172 = 810 / 5 = 162

The mean height is 162 cm

The new mean height

Again we're going to do the same thing

157 + 158 + 161 + 162 + 169 + 172 = 979/6 = 163.16666 = 163 cm

Hence the first mean height is 162 cm and the new mean height is 162 cm

Express the statement as an equation. (Use k as the constant of proportionality.). A varies inversely as r. Use the given information to find the constant of proportionality. If r = 3, then A = 7. k=

Answers

The equation expressing the statement is A = k/r, where k is the constant of proportionality. Given that r = 3 and A = 7, the constant of proportionality can be found by rearranging the equation to k = A × r and substituting the given values to calculate: k = 7 × 3 = 21.

The statement "A varies inversely as r" can be expressed mathematically as an equation: A = k/r, where k is the constant of proportionality. This equation states that A is proportional to 1/r, meaning that as r increases, A decreases, and as r decreases, A increases. To find k, we can rearrange the equation to k = A × r and substitute the given values. In this case, if r = 3 and A = 7, then k = 7 × 3 = 21. Therefore, the constant of proportionality is 21. This equation can be used to determine the values of A, given a value of r, or the values of r, given a value of A. For example, if r = 4, then A = k/4 = 21/4 = 5.25. Conversely, if A = 10, then r = k/A = 21/10 = 2.1. This equation can be used to determine the values of A and r for any given situation.

Solve the inequality. Express your solution using interval notation. graph the solution set. -5(x-3) ≥ 3[4-(x+4)]

Answers

On solving the provided question we can say that The inequality we have here is  -5(x-3) ≥ 3[4-(x+4)] => 15/17 ≥ x

What is inequality?

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

The inequality we have here is

-5(x-3) ≥ 3[4-(x+4)]

-5x + 15 ≥ 12x
