Answer:

5,8

Step-by-step explanation:

since C is on y coordinate 8 if its a reflection C' will be as well and C is on x coordinate -5 so if its a reflection then C' will be 5 so 5,8

Answer:

(5,8)

Step-by-step explanation:

one way I like to do it is a) count how many squares C is away from the axis, which is 5, and then staring at the Y-axis count five spaces to the right, or b) which might be a little more time consuming, do where the original D is and see how many spaces up and across C is from D, which is up two and right 5. So then go to the new one, and go up two and instead of going right five, count five to the left because it's reflected. Hope that made sense and helped! If not please let me know and i'll try to explain further.

The amount of money that you will have in eight years from today is $29,315.79 (rounded to 2 decimal places).

To find out the amount of money that you will have in eight years, you need to use the future value formula, which is:FV = PV × (1 + r)n

Where, FV = future value

PV = present value (initial investment) r = annual interest rate (as a decimal) n = number of years

First, you need to find the future value of the gift amount of $17,000 in two years.

Since it's a gift and not an investment, we can assume an interest rate of 0%.

Therefore, the future value would simply be:

PV = $17,000r = 0%n = 2 years

FV = $17,000 × (1 + 0%)2FV = $17,000

Now, you will loan that amount at 9.75% interest for six more years.

So, you need to find the future value of $17,000 after 6 years at an annual interest rate of 9.75%.

PV = $17,000

r = 9.75%

n = 6 years

FV = $17,000 × (1 + 9.75%)6

FV = $29,315.79

Therefore, the amount of money that you will have in eight years from today is $29,315.79 (rounded to 2 decimal places).

The probability of either A or B occurring is 0.5. The probability that neither A nor B will happen is also 0.5.

It is given that events A and B are mutually exclusive, meaning there is no intersection that is they are independent events. In simple terms, A and B are occurring at different times.

P(A or B) = P(A) + P(B) = 0.30 + 0.20 = 0.50

So the probability of either A or B occurring is 0.5.

Also, the total probability of the event is 1.

So to find the Probability of (neither A nor B):

P complement = 1 - P(A or B) = 1 - 0.50 = 0.50

So a,=0.5 and b,= 0.5

The  length of each congruent side of the isosceles triangle is given to be equal 2.75 inches while the base calculated to be equal to 23.5 inches

We first have to define x as the length of the congruent side. The question tells us that the base is 7 inches longer than 3x the length of 2 sides

This would be represented as:

= 3(2x) + 7

= 6x + 7

The perimeter of the shape is said to be 29, hence we would have

x + x + (6x + 7) = 29

= 2x + 6x + 7 = 29

= 8x = 29 - 7

8x = 22

x = 22 / 8

= 2.75

Given the value of x we would have to put it in

6x + 7

= 6 x 2.75 + 7

= 23.5

Therefore the  length of each congruent side of the isosceles triangle is given to be equal 2.75 inches while the base calculated to be equal to 23.5 inches

The test statistic for this hypothesis test is approximately -2.748. Americans spend less than 7 hours a week answering their email.

To find the test statistic, we need to perform a hypothesis test to determine if the sample data supports the researcher's suspicion that Americans spend less than 7 hours a week answering their email.

Let's set up the null and alternative hypotheses:

Null hypothesis (H₀): The population mean number of hours Americans spend answering their email per week is 7 or more

Alternative hypothesis (H₁): The population mean number of hours Americans spend answering their email per week is less than 7

Next, we can calculate the test statistic, which is the standardized value that measures the distance between the sample mean and the hypothesized population mean, considering the sample size and variability.

The test statistic formula for a one-sample t-test is given by:

t = (sample mean - hypothesized mean) / (sample standard deviation / √sample size)

Given the information from the study:

Sample mean = 6.01

Sample standard deviation (s) = 8.96

Sample size (n) = 617

Hypothesized mean  = 7

Substituting these values into the formula, we get:

t = (6.01 - 7) / (8.96 / √617)

Calculating this expression gives us the test statistic.

t = (-0.99) / (8.96 / √617)

t ≈ -0.99 / (8.96 / 24.81)

t ≈ -0.99 / 0.3602

t ≈ -2.748

Therefore, the test statistic for this hypothesis test is approximately -2.748.

The test statistic provides a measure of how far the sample mean is from the hypothesized mean in terms of standard deviations. In this case, since the test statistic is negative, it suggests that the sample mean is less than the hypothesized mean, supporting the researcher's suspicion that Americans spend less than 7 hours a week answering their email.

The points of solution that are obtained for the system of linear equations 3x + 2y = 11 and -8x - 4y = -20 are (-1,7).

2(3x + 2y = 11)

1(-8x - 4y = -20)

3x + 2y - 8x - 4y = 11 - 20 gives -5x - 2y = -9

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The system of linear equations are -

3x + 2y = 11....(1)

-8x - 4y = -20....(2)

When solved initially the value of equation is -

3x + 2y - 8x - 4y = 11 - 20

-5x - 2y = -9

Multiply equation (1) by 2 -

2(3x + 2y) = 2 × 11

6x + 4y = 22.....(3)

Simplify the equation (2) and (3) by adding -

-8x - 4y + 6x + 4y = -20 + 22

-2x = 2

x = -1

Substituting the value of x = -1 in equation (1) -

3x + 2y = 11

3(-1) + 2y = 11

Simplifying the equation -

-3 + 2y = 11

2y = 11 + 3

2y = 14

y = 7

Therefore, the final value is obtained as (-1,7).

Using Benford's law, based on the probability that amount's first digit of a randomly chosen invoice is an 8 or a 9 is 0.097, a) you expect to examine 10.309 invoices until you get one that begins with an 8 or 9. b) If you don't get an amount starting with an 8 or 9 until the 40th invoice, then the probability of this happening is 0.0000124, which is a very low probability, which suggests that the invoice amounts may not be genuine.

According to Benford's law, the given probability that the first digit of the amount of a randomly chosen invoice is an 8 or a 9 is 0.097.

(a) The expected number of invoices to examine until you get one that begins with an 8 or 9 can be calculated using the formula

E(X) = 1/p, where p is the probability of the desired outcome.

In this case, p = 0.097, so E(X) = 1/0.097 = 10.309. Therefore, you can expect to examine about 10 invoices until you get one that begins with an 8 or 9.

(b) If you don't get an amount starting with an 8 or 9 until the 40th invoice, you may suspect that the invoice amounts are not genuine.

To compute an appropriate probability to support your answer, you can use the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successes, and p is the probability of success.

In this case, n = 39, k = 0, and p = 0.097. So, P(X = 0) = (39 choose 0) * 0.097^0 * (1-0.097)^(39-0) = 0.023. This means that the probability of not getting an amount starting with an 8 or 9 in the first 39 invoices is 0.023, which is quite low. This supports the suspicion that the invoice amounts may not be genuine.

To simplify the given expression, let's break it down step by step:

- Negative 2 a squared b a squared: This term remains the same in the simplified expression.

- Minus 5 a b: This term remains the same in the simplified expression.

- 3 a b squared minus b squared: This can be simplified as (3 a b squared) - (b squared) = 3 a b squared - b squared.

- 2 (a squared b 2 a b): This can be simplified as 2 (a squared b) - 2 (a b) = 2 a squared b - 2 a b.

Now, combining all the simplified terms, we have:

-2 a squared b a squared - 5 a b + 3 a b squared - b squared + 2 a squared b - 2 a b

Simplifying further, we can group like terms:

-2 a squared b + 2 a squared b - 5 a b - 2 a b + 3 a b squared - b squared

Combining like terms, we get:

0 - 7 a b + 3 a b squared - b squared

If 830 grams = 1 day.

23.24 kilograms = 4 weeks.

23.24 kilograms were used by Sebastian in those 4 weeks.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 3x = 4 is an equation.

We have,

830 grams is used each day.

830 grams = 1 day ___(1)

1 week = 7 days

Multiply 4 on both sides.

4 weeks = 28 days ___(2)

From (1) and (2) we get,

4 weeks = 28 days

4 weeks = 28 x 1 day

4 weeks = 28 x 830 grams

4 weeks = 23240 grams ____(3)

1000 grams = 1 kg

Multiply both sides by 23240/1000.

23240 grams = 23.24 kilograms _____(4)

What is radioactive decay?

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Here,

The half-life of the reaction is defined as the time required by a substance to reach half its initial concentration. It is represented by t(1/2)

 All radioactive decay processes follow the first-order reaction.

The equation for the half-life for first-order reaction follows:

t(1/2) = 0.693/k....(1)

where,

k = rate constant of a first-order reaction

Given value:

t(1/2) = 5715 years

Put the value of t in equation (1), and we get

k = 0.693/5715

k = 1.21×10⁻⁴yr

The integrated rate law expression for first-order reaction follows:

t = 2.303/k×㏒(a/(a-x))

where,

t = time period

a = initial concentration of the reactant = 58.2 counts per minute

(a-x) = Concentration of reactant left after time t = 38.0 counts per minute

k = rate constant of a first-order reaction

Put the values in the equation and we get

t = 2.303/1.21×10⁻⁴㏒58.2/38

t = 3523.77 years.

Hence, the age of the artifact is 3523.77 years.
