Step-by-step explanation:

Using the mean formular, the sum of the four scores that are not the median would be 360.

Average or mean score = 450 / 5

Mean score = 90

Hence, median score = mean score = 90

The sum of the 4 scores that are not the median can be calculated thus :

Sum of the 4 scores = 450 - 90 = 360

Hence, the sum of the 4 scores that are not the median is 360.

this is just a simplified situation. normally people have more deductions from their salary than just taxes.

but anyway,

100% = $52,000

1% = 100%/100 = 52000/100 = $520

20% = 20×1% = 20 × 520 = $10,400

so, she pays $10,400 taxes.

and that leaves her from her salary

52000 - 10400 = $41,600

as net pay.

FYI - to calculate the remaining amount, we could have also done the following :

20% get deducted, so, 80% remain.

80% = 80×1% = 80 × 52000/100 = 52000 × 80/100 =

Answer:

I graphed it, the first one is correct .

(a) The mean of Z in case (a) is -60 and the variance is 400.

(b) The mean of Z in case (b) is 280 and the variance is 3600.

(c) The mean of Z in case (c) is 60 and the variance is 65.

(d) The mean of Z in case (d) is -20 and the variance is 65.

(e) The mean of Z in case (e) is 80 and the variance is 505.

To find the mean and variance of the random variable Z for each case, we can use the properties of means and variances.

(a) Z = 40 - 5X

Mean of Z:

E(Z) = E(40 - 5X) = 40 - 5E(X) = 40 - 5 * 20 = 40 - 100 = -60

Variance of Z:

Var(Z) = Var(40 - 5X) = Var(-5X) = (-5)² * Var(X) = 25 * Var(X) = 25 * (4)² = 25 * 16 = 400

Therefore, the mean of Z in case (a) is -60 and the variance is 400.

(b) Z = 15X - 20

Mean of Z:

E(Z) = E(15X - 20) = 15E(X) - 20 = 15 * 20 - 20 = 300 - 20 = 280

Variance of Z:

Var(Z) = Var(15X - 20) = Var(15X) = (15)² * Var(X) = 225 * Var(X) = 225 * (4)² = 225 * 16 = 3600

Therefore, the mean of Z in case (b) is 280 and the variance is 3600.

(c) Z = X + Y

Mean of Z:

E(Z) = E(X + Y) = E(X) + E(Y) = 20 + 40 = 60

Variance of Z:

Var(Z) = Var(X + Y) = Var(X) + Var(Y) = (4)² + (7)² = 16 + 49 = 65

Therefore, the mean of Z in case (c) is 60 and the variance is 65.

(d) Z = X - Y

Mean of Z:

E(Z) = E(X - Y) = E(X) - E(Y) = 20 - 40 = -20

Variance of Z:

Var(Z) = Var(X - Y) = Var(X) + Var(Y) = (4)² + (7)² = 16 + 49 = 65

Therefore, the mean of Z in case (d) is -20 and the variance is 65.

(e) Z = -2X + 3Y

Mean of Z:

E(Z) = E(-2X + 3Y) = -2E(X) + 3E(Y) = -2 * 20 + 3 * 40 = -40 + 120 = 80

Variance of Z:

Var(Z) = Var(-2X + 3Y) = (-2)² * Var(X) + (3)² * Var(Y) = 4 * 16 + 9 * 49 = 64 + 441 = 505

Therefore, the mean of Z in case (e) is 80 and the variance is 505.

Therefore, the common point for all functions of the form fx = bx is (1, 1), which corresponds to option A.

Let's consider functions of the form fx = bx, where b is a constant. When we substitute x = 0 into this function, we get:

f(0) = b * 0 = 0

So, for any value of b, when we evaluate the function at x = 0, the output is always 0. However, the point (0, 0) is not common to all functions of the form fx = bx because the value of b determines the behavior of the function.

To find the common point for all functions of the form fx = bx, we need to find the value of b that satisfies the condition for all cases. If we substitute x = 1 into the function, we have:

f(1) = b * 1 = b

So, for the common point to hold, we need f(1) to be equal to 1. This implies that b = 1.

Answer:

40% change

Step-by-step explanation:

6/10=40%

Correct option is A,  f(x) -2 has changed the parent function f(x) = (0.5)x to its new appearance.

The parent function f(x) = log5x has been modified by reflecting it over the x-axis, extending it vertically by a factor of three, and moving it down by three units.

In the picture below you can see the blue line is the graph of the function

f(x) = log(5x) and the green line is the graph of the function

g(x) = log[5(x + 4)] - 2

Since the function f passes at point (2, 1), we must reduce it by 2 units to ensure that it also passes at position (-2, -1). To do this, we add 2 to the function f.

We only need to add 4 to the variable x to have the function go left when we obtain log(5x) - 2.

The function shifts to the left when you add a number to x;

The function moves to the right when you remove a number from x;

The function increases when you add a number to it;

The function decreases when you take a number away from it.

Then we get a function g(x) = log[5 (x + 4)] - 2.

There are only two ways that X might be greater than three: X is equal to four, or X is equal to five, increasing the likelihood that X is greater than three. Therefore, the likelihood of being more than three is equal to the likelihood of being four. Additionally, the likelihood of being five, These probability are.03 and.02, which equals C.

Yes. A leg of a right triangle can indicate the distance that separates two vertical or horizontal points, and the hypotenuse can represent the distance between two non-vertical or non-horizontal points.

We can use this theorem to calculate the distances between two locations on a coordinate grid. Consider the following example using the points:

( 3, 4 ) and ( − 2, 1 )

We can see how to make a right triangle with the hypotenuse as that of the line connecting these two spots. A right angle is formed at the coordinates ( 3, 1), where the vertical line from ( 3, 4 ) and the horizontal line from ( 2, 1 ) intersect.

To find the amounts of each canned juice drink needed to obtain 15L of a 21% orange juice mixture, we can use a mixture equation.

Let's assume we need x liters of the 25% orange juice drink and y liters of the 10% orange juice drink.

To set up the equation, we need to consider the amount of orange juice in each drink. The 25% orange juice drink contains 25% of x liters of orange juice, while the 10% orange juice drink contains 10% of y liters of orange juice.

To find the total amount of orange juice in the mixture, we add the amounts of orange juice from each drink:

0.25x + 0.10y = 0.21 * 15

Simplifying this equation, we have:

0.25x + 0.10y = 3.15

To solve for x and y, we can use substitution or elimination.

Let's use the substitution method. Solve the first equation for x:

x = (3.15 - 0.10y) / 0.25

Substitute this value of x into the second equation:

0.25 * [(3.15 - 0.10y) / 0.25] + 0.10y = 3.15

Simplifying, we get:

3.15 - 0.10y + 0.10y = 3.15

The variable y cancels out, leaving us with:

3.15 = 3.15

This equation is always true, which means that y can take any value.

Therefore, there are infinite combinations of the two juice drinks that can be mixed to obtain 15L of a 21% orange juice mixture. The specific values of x and y will depend on the chosen combination.

For example, if we let y = 0, meaning we use only the 25% orange juice drink, then x would be 15L. On the other hand, if we let x = 0, meaning we use only the 10% orange juice drink, then y would be 15L.

In summary, to obtain 15L of a 21% orange juice mixture, you can mix any amount of the 25% and 10% orange juice drinks as long as the total amounts of orange juice from each drink add up to 3.15L (which is 21% of 15L).

Answer:

The answer is x = \(\frac{-5}{3}\).

Step-by-step explanation:

First, we expand the brackets. Therefore:

\(2x+6 = -4x+(-4)\)

\(2x+6 = -4x -4\)

Then, we separate the like terms:

\(2x+4x = -4-6\)

Then we add the like terms up and solve for x:

\(6x = -10\)

Therefore:

\(x = \frac{-10}{6}\)

which, simplified, is:

\(x = \frac{-5}{3}\).

If marbles of the same color are indistinguishable, then we can treat each color as one "block" of marbles. Therefore, we have three blocks - one with 3 red marbles, one with 4 yellow marbles, and one with 4 green marbles.

The number of ways to arrange these blocks in a line is simply the number of ways to rearrange the 3 blocks. This is given by 3! which is equal to 6, Within each block, the marbles of the same color are indistinguishable, so we don't need to worry about arranging them.

Therefore, the total number of ways to arrange the marbles in a line is 6, Since marbles of the same color are indistinguishable, we will use the formula for permutations with indistinguishable items. The formula is:

Total permutations = n! / (n1! * n2! * n3! ... nk!) Using the formula, the number of ways to arrange the marbles in a line is:
Total permutations = 11! / (3! * 4! * 4!) = 39,916,800 / (6 * 24 * 24) = 13,860 So, the boy can arrange the marbles in 13,860 different ways if marbles of the same color are indistinguishable.

Answer:

y= -2.8

x = 1.2

Explanation:

y has been give so first substitute y into y

y=6x−10 and y=x−4

so x-4 = 6x-10

now get all the like terms on one side

it's best to keep the x as postive for easier methods so move the x to the rights side by subtracting x from the left side.

x-4 = 6x-10

- x

-4 = 6x - 10

now add 10 so x's are on one side and the numbers on the other

+ 10

-4 + 10 = 6x - x

now simplify

-4 + 10 = 6

6x - x = 5x

so

6 = 5x

divide by 5 to get X by itself, the value of x

x = 6/5 = 1.2

now we have the value of x we can substitute it to find the value of y.

y=x−4

x = 1.2

y= 1.2 - 4 =-2.8

y= -2.8

x = 1.2

The dimensions of the original sandbox was 2 ft X 2 ft..

Let, The original has a length of Xft and a width of Xft

The area of original sandbox is X^2 ft^2

As per given statement,

The new sandbox would have a length of (X+4)ft and a width of (X+5)ft

So, the area of new sand box would be: (X+4)(X+5) ft^2

Given, the area of new sandbox will be 38 square feet greater than the area of the original sandbox.

so,

X^2+38 = (X+4)(X+5)

or, X^2+38 = X^2 + 9X + 20

Eliminating X^2 from both side

0r, 9X+ 20 = 38

0r, 9X = 18

The function is increasing for all real values of x where x < –4.

The statement that is true about the function is: "The function is decreasing for all real values of x where x < -4."

In order to determine the behavior of the function, we look at the given options. Among the options, the only statement that aligns with the function being decreasing is the one that states the function is decreasing for all real values of x where x < -4.

If a function is decreasing, it means that as the value of x decreases, the value of the function also decreases. In this case, it indicates that as x becomes more negative, the function's values decrease.

The Confidence Interval for the hypothesis test at the 5% level to determine if 68% represents California is 0.65, 0.90.

First, we need to find H₀ and Hₐ. In this case, we want to check whether California community colleges take 68% of the online classes thought by full-time faculties, or not.

H₀ : p = 0.68; Hₐ : p ≠ 0.68

Second, we need to determine the distribution needed. State what our random variable P’ represents.

Normal: N

Test Statistic : z = 0.1873

Third, we have to calculate he p-value using the normal distribution for proportions.

p-value = 0.1873

If the null hypothesis is true (the proportion is 0.68), thus there is a 0.1873 probability which the estimated proportion is 0.773 or more.

Fourth, we need to compare \(\alpha\) and the p-value, then indicate the correct decision (reject or do not reject the null hypothesis).

\(\alpha\) = 0.05

Decision : Do not reject the null hypothesis

Reason for decision : p-value > 0.05

At the 5% level, the data do not provide statistically significant evidence that the true proportion of online courses taught by full-time faculty is not 68%.

The probability that in a random sample of 190 Americans aged 14 or older, more than 27 are single is approximately 0.9975

To solve this problem, we can use the normal approximation to the binomial distribution.

First, we need to calculate the mean and standard deviation of the number of singles in a sample of 190 Americans aged 14 or older.

Mean

μ = n × p = 190 × 0.22 = 41.8

Standard deviation

σ = sqrt(n ×p × (1 - p)) = sqrt(190 × 0.22 × (1 - 0.22)) = 5.27

Now, we can use the standard normal distribution to calculate the probability that more than 27 people in the sample are single. We convert the binomial distribution to a normal distribution by using the following formula

z = (x - μ) / σ

where x is the number of singles in the sample.

z = (27 - 41.8) / 5.27 = -2.80

Using a standard normal distribution table or calculator, we can find that the probability of getting a z-score of -2.80 or lower is approximately 0.0025.

However, we want to find the probability of getting more than 27 singles, so we need to find the area to the right of z = -2.80. This is equivalent to subtracting the probability of getting a z-score of -2.80 or lower from 1:

P(Z > -2.80) = 1 - 0.0025 = 0.9975

C(x,y)=800x+1000y

The first constraint is that the company needs to have 12 IBM copying machines serviced and we know that contractor A can repair 2 IBM copying machines and contractor B can repair 1 IBM copying machines. This translates into the following inequality.

2x+y≥12

The second constraint is that the company needs 18 Xerox copying machines serviced and we know that contractor A can repair 1 Xerox copy machines while contractor B can repair 3 Xerox copy machines. This translates into the following inequality.

x+3y≥18

The third constraint is that the company needs 20 Canon copying machines serviced and we know that contractor A and contractor B can repair 2 Canon copy machines each. This translates into the following inequality.

2x+2y≥20

The fact that x and y must be positive numbers is represented by the following two constraints:

x≥0,y≥0

Using all of this information, our problem is as follows.
