Answer: (5,3)
Step-by-step explanation:
Solve by Addition/Elimination
x + y = 8
3x − y = 12
Add the two equations together to eliminate y from the system.
x + y = 8
+ 3x −y = 12
4x = 20
Divide each term in 4x = 20 by 4.
4x = 20
4 4
Cancel the common factor of 4.
x= 20/4
x = 5
Substitute the value found for x into one of the original equations to solve for y.
(5) + y = 8
Remove parentheses.
5 + y = 8
Move all terms not containing y to the right side of the equation.
Subtract 5 from both sides of the equation.
y = 8 − 5
Subtract 5 from 8.
y = 3
The solution to the independent system of equations can be represented as a point.

The result can be shown in multiple forms.

There are 3 people in a room, and we are curious whether two of them have their birthday in the same month. We record the triplet that describes the month of birthday for each person. E.g. (Oct, Jan, Jul) is one possible triplet/outcome. (Since each month applies to a specific person, (Oct, Jan, Jul) is not the same as (Jan, Jul, Oct) and so order is important.) a. How many possible outcomes are there
Answers
Answer:
The possible outcomes are 1728.
Step-by-step explanation:
Consider the provided information.
We know that there are 12 months in a year and we have 3 people in a room.
As the order is important it means for each person we have 12 choices of the months.
The possible outcomes are: [tex]12\times12\times12=1728[/tex]
Hence, the possible outcomes are 1728.

A bag contains 9 RED beads, 8 BLUE beads, and 3 GREEN beads. If a single bead is picked at random, what is the probability that the bead is RED or GREEN
Answers
Answer:
0.6 = 60% probability that the bead is RED or GREEN.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 9 + 8 + 3 = 20 beads.
Of those, 9 + 3 = 12 are red or green.
So, there is a [tex]\frac{12}{20} = 0.6[/tex] probability that the bead is RED or GREEN.

A National Retail Federation survey found households intend to spend an average of $469 during the December holiday season. Assume that the survey included 600 households and that the sample variance was $375. Calculate the margin of error for a 99% confidence interval.
Answers
Answer:
The margin of error for a 99% confidence interval was of $1.84.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.005 = 0.995[/tex], so [tex]z = 2.325[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation(square root of the variance) and n is the size of the sample. In this question, [tex]\sigma = \sqrt{375}, n = 600[/tex]
So
[tex]M = z*\frac{\sigma}{\sqrt{n}} = 2.325\frac{\sqrt{375}}{\sqrt{600}} = 1.84[/tex]
The margin of error for a 99% confidence interval was of $1.84.

You have a box of chocolates (30 chocolates in the box). 15 are filled with caramel, 10 are filled with chocolate, and 5 are filled with cream. You and a friend pick a chocolate at random. What is the probability that you both pick chocolate
Answers
Answer:
10.34% probability that you both pick chocolate
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, it is not important if you or your friends picks first. So we use the combinations formula to find the number of desired and total outcomes.
Combinations Formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
10 are filled with chocolate, and we want to pick 2. So
[tex]D = C_{10,2} = \frac{10!}{2!(10-2)!} = 45[/tex]
Total outcomes:
The box has 30 chocolates, and 2 are picked, so:
[tex]T = C_{30,2} = \frac{30!}{2!(30-2)!} = 435[/tex]
Probability:
[tex]P = \frac{D}{T} = \frac{45}{435} = 0.1034[/tex]
10.34% probability that you both pick chocolate

[tex](x + 8)^2 = 55[/tex]
Step-by-step explanation:
Given
[tex]x^2 + 16x + 17 = 8[/tex]
Required
Get an equivalent equation
[tex]x^2 + 16x + 17 = 8[/tex]
Subtract 17 from both sides
[tex]x^2 + 16x + 17-17 = 8-17[/tex]
[tex]x^2 + 16x = -9[/tex]
Add 64 to both sides
[tex]x^2 + 16x + 64 = -9+64[/tex]
[tex]x^2 + 16x + 64 = 55[/tex]
Expand the expression on the left-hand side
[tex]x^2 + 8x + 8x + 64 = 55[/tex]
Factorize:
[tex]x(x + 8) + 8(x + 8)= 55[/tex]
[tex](x + 8)(x + 8)= 55[/tex]
[tex](x + 8)^2 = 55[/tex]

Suppose a normally distributed set of data with 7800 observations has a mean of 188 and a standard deviation of 18. Use the 68-95-99.7 Rule to determine the number of observations in the data set expected to be below a value of 242. Round your result to the nearest single observation.
Answers
Answer:
7788 observations are expected to be below a value of 242.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 188, standard deviation = 18
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.
Percentage of observations below 242:
242 = 188 + 3*18
So 242 is three standard deviations above the mean
Of the measures below the mean, all are below 242.
Of the measures above the mean, 99.7% are between the mean of 188 and three standard deviations above the mean(242). So the percentage is:
[tex}P = 0.5 + 0.997*0.5 = 0.9985[/tex]
Number of observations below 242:
99.85% of 7800 observations
0.9985*7800 = 7788
7788 observations are expected to be below a value of 242.
