The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for the IQ scores are given as follows:

She had to pay they have to pay her back $ 132.

Multiply: -

Payback = 360 x 120/100

               = 132

Payback is a financial metric that measures the time it takes to recover the initial investment cost of a project. It is commonly used in investment analysis to evaluate the viability of potential projects by estimating the time it takes for the project to start generating profits.

The payback period is calculated by dividing the initial investment by the expected cash flow of the project on an annual or monthly basis until the investment is fully recovered. The shorter the payback period, the more attractive the project is to investors. Payback is a simple and straightforward metric, but it has some limitations. It does not consider the time value of money or the long-term profitability of the project.

The measure of angle A is 83 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

In the triangle ABC, ∠A=(12x-1)º, ∠B=10x and ∠C=3x+6

Now we need to find the value of angle A.

We know that from angle sum property that the sum of three angles is 180 degrees.

∠A+∠B+∠C=180

12x-1+10x+3x+6=180

25x+5=180

25x=175

Divide both sides by 25

x=175/25

x=7

Answer:

  6 years

Step-by-step explanation:

You want the length of time it takes for a $50 investment to total $3200 if it doubles in value each year.

The value of the investment can be described by ...

  v = 50·2^t

where t is the number of years.

You want t when v=3200:

  3200 = 50·2^t

  64 = 2^t

  log(64) = t·log(2) . . . . . take logarithms

  t = log(64)/log(2) = 6

It will take 6 years for her investment to reach $3200.

If you're familiar with powers of 2, you recognize that 64 = 2⁶. Comparing exponents in ...

The formula (D) f(n) = 65 − 9(n − 1) represents the arithmetic sequence for 65, 56, 47, 38, 29 ….

An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k.

In a geometric sequence, each term rises by dividing by or multiplying by a certain constant k.

For instance, a1 = 25 and a(n) = a(n-1) + 5.

Each word in an arithmetic sequence increases by adding or subtracting a certain constant, k.

As opposed to a geometric sequence, where each term is increased by dividing or multiplying a certain constant k, this one does not.

For instance, a(n) = a(n-1) + 5 and a1 = 25.

So, we have the sequence:

65, 56, 47, 38, 29 …

Now, the difference is 65 - 56 = -9

Now, the first term is 65.

Then, the equation which represents its formula is f(n) = 65 − 9(n − 1).

Answer: The best graph to illustrate June's situation is a cost-volume-profit (CVP) graph, which shows the relationship between the revenue, cost, and volume of goods sold.

In June's case, her fixed costs (the cost of the sewing machine) are constant and do not change regardless of the number of quilts she makes and sells. Her variable costs (the raw materials) are directly proportional to the number of quilts she makes and sell. Her revenue is directly proportional to the number of quilts she sells.

The CVP graph will show a line representing fixed costs, a line representing variable costs, and a line representing revenue. The point at which the total costs (fixed costs + variable costs) equal the revenue represents the break-even point, at which June neither makes a profit nor incurs a loss. Beyond this point, June will make a profit, and before this point, she will incur a loss.

The CVP graph can be used to determine the break-even point and to make predictions about the future financial performance of a business, based on changes in volume, costs, or price.

The measure of each angle in complementary angles with measures 3x and 6x - 18 degrees is 36° and 54°.

We are given two angles 3x and 6x - 18 and these angles are complementary angles.

Complementary angles are those whose combined angle is 90 degrees or less. In other terms, two angles are said to be complimentary if they combine to make a right angle.

So, sum of 3x and 6x - 18 is 90°

     3x + 6x - 18 = 90°

                    9x = 108°

                      x = 12°

So, 3x = 3 × 12 = 36°

     6x - 18 = 6 × 12- 18 = 54°

Hence, the measure of each angle is 36° and 54°.

John has 2 books

Peter has twice books more than John = 2 * 2 = 4 books

Total books they have together = 2 + 4 = 6 books

John has 2 books, so Peter has twice books more than John. This means that Peter has 2 * 2 = 4 books. Together, John and Peter have 2 + 4 = 6 books. John’s books are the starting point of the problem, so it is important to keep track of John’s books. Since Peter has twice books more than John, we can calculate the number of books that Peter has by multiplying the number of books that John has by two. Once we have calculated the number of books that Peter has, we can add the number of books that John has to the number of books that Peter has and get the total number of books that they have together. In this example, the total number of books that John and Peter have together is 6. This can be arrived at by adding the number of books that John has (2) to the number of books that Peter has (4).

2) Add like terms 8y and 4y to get 12y. Our new equation is -36=12y-24.

3) Remove the constant -24 by adding 24 to both sides to get -12=12y.

4) Remove the coefficient 12 by dividing 12 on both sides to get y= -1  

If reid takes a 2 quart pitcher of lemonade to the table and pours it all equally into 9 glasses, each glass contains approximately 0.888 cups (or 7/8 cups) of lemonade.

The problem states that Reid has a 2 quart pitcher of lemonade, which is equivalent to 8 cups. This is because there are 4 cups in one quart, so 2 quarts would be 2 x 4 = 8 cups.

Reid pours this entire amount of lemonade equally into 9 glasses. This means that the amount of lemonade in each glass will be the same. To find out how much lemonade goes in each glass, we need to divide the total amount of lemonade by the number of glasses.

We can use the following formula:

amount per glass = total amount / number of glasses

Plugging in the values we know, we get:

amount per glass = 8 cups / 9

Dividing 8 cups by 9 gives us a decimal value of 0.888..., which means that each glass contains approximately 0.888 cups of lemonade. This value is an approximation, since we rounded to the nearest thousandth place.

We can also express this value as a fraction by simplifying 0.888... as follows:

0.888... = 888.../1000...

= 8/9

Therefore, we can say that each glass contains 7/8 cups or approximately 0.888 cups of lemonade.

To determine Km from a double-reciprocal plot, you would choose option (A) which is to multiply the reciprocal of the x-axis intercept by -1.

In the double-reciprocal plot equation, the x-axis intercept is -1/Km, and the y-axis intercept is 1/Vmax. Therefore, if you take the reciprocal of the x-axis intercept, you get -Km, and multiplying it by -1 gives you Km.

This method is preferred because it is more accurate than estimating Km based on the position of the curve on the plot or by taking the x-axis intercept where V0 = 1/2 Vmax, which can be influenced by experimental error.
