Hey there the answer is 370

Step-by-step explanation:

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.

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.

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.

  (5, 3)

The result can be shown in multiple forms.

Point Form:

  (5, 3)

Equation Form:

  x = 5, y = 3

Step-by-step explanation:

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.

Answer:

You're both learning the same stuff, only in different environments.

Step-by-step explanation:

It doesn't matter about the different environments you are in, you are still learning the same schoolwork that you are required to do.

Answer:

The similarity between online school and in- person is the material learned and how it is taught.

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

Answer:

By adding 6 ounces of chemical B in the mixture

Step-by-step explanation:

Ratio of chemical A and B in compound

A/B=8/12

Ratio of chemical A and B in mixture

A/B=24/30

if we add 6 in denominator

A/B=24/36=8/12

Answer:

First one is infinitely many solutions. Second one is One solution. The third one is No solution.

Step-by-step explanation:

First line both equations have the same line. second one are two completely different equations while the third one are parallel lines which never intersect.

Possible outcomes of a coin toss are a head or a tail.

Since the coin is tossed three times, there'll be six possible outcomes.

H H H T T T - Possible outcomes

The possibility of a head appearing at least once is therefore 1/3.

Hope it helps. :)

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.

Answer:

80 degrees is what I got im not 100 percent its right

Answer:

[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]
