Answer:

102 adults, 165 children

Step-by-step explanation:

Let a be the number of adults, and let c be the number of children. We set up and solve this system of equations:

a + c = 267---------> 7a + 7c = 1869

12a + 7c = 2379------->12a + 7c = 2379

-----------------------

5a = 510

a = 102, c = 165

Answer:

10:2, 15:3, 20:4, etc.

Step-by-step explanation:

Well just keep going, they all simplify back to 5:1

The required equivalent ratios are,

\(10:2\\15:3\\20:4\\\)

Equivalent ratios are the ratios that are the same when we compare them. Two or more ratios can be compared with each other to check whether they are equivalent or not.

For example, 1:2 and 2:4 are equivalent ratios.

The given ratio is,

\(5:1\)

Now, as we know that we can convert the given ratio into fractions.

\(\frac{5}{1}\)

Now, for finding the equivalent ratios multiply the same constant in both the numerator and denominator.

So, the required ratios are,

\(\frac{5\times2}{1\times 2} =\frac{10}{2}=10:2\\ \frac{5\times3}{1\times 3} =\frac{15}{3}=15:3\\\frac{5\times4}{1\times 4} =\frac{20}{4}=20:4\\\)

And so, on.

Step-by-step explanation:

(212900 + 213500) ÷ 2

426400/2 = 213200

The number exactly halfway between 212,900 and 213,500 is 213,200.

Finding the number that is halfway between two given values is a fundamental concept in mathematics, and it involves a simple calculation using basic arithmetic.

To find the number that is exactly halfway between two values, you need to add the two values together and then divide the sum by 2.

In this case, 212,900 + 213,500 = 426,400.

Dividing 426,400 by 2 gives us 213,200, which is the number exactly halfway between the two given values.

Therefore, 213,200 is the answer to the question.

The experiment is not a binomial experiment because the probability of choosing a green marble is not same for each drawing

An experiment consisting of a fixed number of independent trials each with two possible outcomes, success and failure .

The experiment is not  a binomial experiment because the probability of choosing a green marble is not the same for each as after drawing the marble from hat , he is laying the marble aside and not putting it back into the hat  which altered the probability every time because total number of marbles are decreasing after every turn of drawing.

Answer: 5/7 of the kids chose New York or L.A.

Step-by-step explanation:

All you need to do in this problem is add the fraction of people that chose New York and the fraction of people that chose L.A:

4/7 + 1/7 = 5/7

The conditions necessary for this problem are

1)The trials are independent,

2) There are only two possible outcomes for each trial

3) The probability of success is constant

4) The sample size is fixed

For this problem to be analyzed using the binomial random variable, the following conditions must be met:

The trials are independent: Each selection of an eligible voter must be independent of the other selections, meaning that the outcome of one selection does not affect the outcome of another.

There are only two possible outcomes for each trial: In this case, the two possible outcomes are that the selected voter will vote or will not vote in the next presidential election.

The probability of success is constant: The probability of success (i.e., the probability that a selected voter will vote) must be the same for each trial.

The sample size is fixed: The number of trials, or the number of selected eligible voters, must be fixed in advance.

Answer: I think its C

Step-by-step explanation:

The class width used for the frequency distribution is 6.

The class midpoint for the class 23-29 is 26.

The class midpoint for the class 30-36 is 33.

The class midpoint for the class 37-43 is 40.

To find the class width of the frequency distribution, we need to determine the range of each age class. The range is the difference between the upper and lower boundaries of each class. Looking at the table, we can see that the class boundaries are as follows:

23-29

30-36

37-43

For the class 23-29, the lower boundary is 23 and the upper boundary is 29. To find the class width, we subtract the lower boundary from the upper boundary:

Class width = 29 - 23 = 6

So, the class width for the frequency distribution is 6.

To find the class midpoint for each class, we take the average of the lower and upper boundaries of each class.

For the class 23-29:

Class midpoint = (23 + 29) / 2 = 52 / 2 = 26

For the class 30-36:

Class midpoint = (30 + 36) / 2 = 66 / 2 = 33

For the class 37-43:

Class midpoint = (37 + 43) / 2 = 80 / 2 = 40

So, the class midpoint for the class 23-29 is 26, for the class 30-36 is 33, and for the class 37-43 is 40.

For the angles to be parallel, the value of x is of x = 28, and the angle is of 132º.

The angles need to have the same measure. Their measures are of 3x + 48 and 6x - 36, hence:

3x + 48 = 6x - 36

3x = 84

x = 84/3

x = 28.

Answer:

(a) 1.645

(b) 2.5758

Step-by-step explanation:

The complete question is: Find Z(\(\alpha\)/2) for the confidence level 90% and for the confidence level 99%.

Firstly, as we know that \(\alpha\) represent the level of significance, i.e;

Level of significance = 1 - confidence level

(a) We are given the confidence level of 90%, so;

     Level of significance = 1 - 90%

                                         = 1 - 0.90 = 0.10 or 10%

Now, \(Z_(_\frac{\alpha}{2}_)\) = \(Z_(_\frac{0.10}{2}_)\) = \(Z_(_0_._0_5_)\)

This means that we have to look for a critical value in the z table at a 5% level of significance which gives us a value of 1.645.

(a) We are given the confidence level of 99%, so;

     Level of significance = 1 - 99%

                                         = 1 - 0.99 = 0.01 or 1%

Now, \(Z_(_\frac{\alpha}{2}_)\) = \(Z_(_\frac{0.01}{2}_)\) = \(Z_(_0_._0_0_5_)\)

This means that we have to look for a critical value in the z table at a 0.5% level of significance which gives us a value of 2.5758.

We need to find which statement is not true:

Let us check each statement:

-They are opposite numbers.

Opposite numbers have the same distance away from zero. Hence, 7 and -7 are opposite numbers.

-They form a zero pair:

7-7 =0, the statement is true.

- They have the same absolute value

The absolute value is the not negative value no matter the sign.

Hence, l7l= 7 and l-7l= 7.

-They have a sum of -14.

Then:

7+(-7) = 0

Therefore, the last statement "They have a sum of -14" is not true.

The value of d that makes (x - d) a factor of p(x) is d = -5.

Given that we need to find the value of d if (x-d) is a factor of the polynomial \(\mathrm{p(x)= 2x^3 -dx^2+(1-d^2)x+5}\).

If (x - d) is a factor of the polynomial \(\mathrm{p(x)= 2x^3 -dx^2+(1-d^2)x+5}\), it means that if we substitute (x = d) into the polynomial, the result should be equal to zero.

In other words, p(d) = 0.

Let's find the value of d by setting p(d) to zero and solving for d:

\(\mathrm{p(d)= 2d^3 -d\cdot d^2+(1-d^2)d+5}\)

To find d, we set p(d) equal to zero:

\(\mathrm{ 2d^3 -d\cdot d^2+(1-d^2)d+5 = 0}\)

Now, let's simplify this equation and solve for d:

0 = 2d³ - d³ - d³ + d + 5

0 = 2d³ - 2d³ + d + 5

0 = d + 5

Now, isolate d:

d = -5

So, the value of d that makes (x - d) a factor of p(x) is d = -5.

Answer:

If y and x have a proportional relationship, then we can write an equation of the form y = kx, where k is a constant of proportionality.

To find the value of k, we can use the given values of y and x:

y = kx

24 = k(12)

k = 2

Now that we know k, we can use the equation to find the value of y when x=16:

y = kx

y = 2(16)

y = 32

Therefore, when x=16, y=32.
