  AB AC BC CB CA BA

Answer:

B

Step-by-step explanation:

So we have:

[tex]\frac{x^{\frac{2}{3}}}{y^{\frac{-3}{4}}}[/tex]

First, we recall that we can switch an exponent from the denominator to the numerator if we multiply the exponent by -1 and vice versa. Therefore:

[tex]=x^{\frac{2}{3}}}\cdot {y^{\frac{3}{4}}[/tex]

Now, use the following property:

[tex]a^{x/n}=\sqrt[n]{a^x}[/tex]

Therefore:

[tex]x^{\frac{2}{3}}=\sqrt[3]{x^2}[/tex]

And:

[tex]y^{\frac{3}{4}}=\sqrt[4]{y^3}[/tex]

And so together:

[tex]=x^{\frac{2}{3}}}\cdot {y^{\frac{3}{4}}\\=\sqrt[3]{x^2}\cdot\sqrt[4]{y^3}[/tex]

Our answer is B :)

Answer:

B

The points the blue marble should be worth for the game to be fair is given by: Option C: 8

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

Expectation can be taken as a weighted mean, weights being the probability of occurrence of that specific observation.

Thus, if the random variable is X, and its probability mass function is given : f(x) = P(X = x), then we have:

[tex]E(X) = \sum_{i=1}^n( f(x_i) \times x_i)[/tex]

(n is number of values X takes)

For the game to be fair, the expected number of points that one can loose should be equal to the expected number of points one can gain.

Now, probability of getting any specific colored marble = 1/5 = 0.2 (since there is one way to choose a specified colored marble, but there are 5 ways to choose a single (no color specified) marble out of 5 marbles.

The game would be fair if there is equal chance of winning and loosing.
Let we have:

Then we need E(X) = expectation of X = 0 (since the negative points of loosing would equate to positive point of winning, thus, making the expected overall score 0, thus, making game fair.

Values of  X = -2(if lost, or say chose any four colored marble except blue marble), or p(if won, or say chose blue colored marble)

(its because choosing one marble from 5 marbles can be done in 5 ways, so n(S) = 5, and choosing 1 blue marble out of 5 different colored marble can be done in 1 way, and choosing 1 non-blue marble out of 5 different colored marble can be done in 4 ways)

Thus, we get:

[tex]E(X) = -2 \times P(X = -2) + p \times P(X = p)\\E(X) = -2 \times 4/5 + p \times 1/5\\0 = -8/5 + p/5\\0 = -8 + p\\p = 8[/tex]

Thus, the points the blue marble should be worth for the game to be fair is given by: Option C: 8

912.80 - 482.36 = 430.44

430.44 divided by 12 = 35.87

Answer:

$35.87

Step-by-step explanation:

Let's first find out how much more they need to raise in total.

912.80 - 482.36 = 430.44

Now, if everyone contributes the same amount, they each need to contribute one twelfth of this amount.

430.44/12 = 35.87

Answer:

-11/2

Step-by-step explanation:

According to the information given, you can write the following:

3(-5/3)-x=1/2, where x is the number that should be subtracted from thrice the rational number -5/3 to get 1/2.

Then, you can solve for x:

-15/3-x=1/2

-5-x=1/2

x=-5-1/2

x=-11/2

According to this, the answer is that -11/2 is what should be subtracted from thrice the rational number -5/3 to get 1/2.

Step-by-step explanation:

"8 times" = 8 must be alone and not being multiplied or subtracted from anything

"the quantity of" is asking for a number

"5 less than 10" = 5, so we must see (10 - 5) in the correct answer

so we get 8 times 5, or 8(10 - 5)

Answer:

Ordinal

Step-by-step explanation:

Level of measurement used in statistics summarizes what statistical analysis that is possible. There exist three types of level of measurement. The nominal, ordinal and Interval/Ratio level of measurement. Here, our primary focus will be the Ordinal level of measurement.

Ordinal level of measurement indicates the position in a sequence. In the military sector, the officer's rank is said to be Ordinal. This implies that the ordinal level of measurement categorizes variables according to hierarchy or ranks with a meaningful order. Still, the intervals and differences between the variables may not be equal.

Answer: x=14 and y=8

*Note: x and y are used as variables to solve the problem. Just know that the sides for one square is 14 and the other, 8.

Step-by-step explanation:

For this problem, we can use system of equations to solve. Let's use x for one side of a square and y for the other.

Equation 1:

x²+y²=260

We get this equation from the sum of the areas. The x² and y² are from the area. Since all sides of a square are equal lengths, we can directly square them.

Equation 2:

4x-4y=24

This equation comes from the difference of the perimeters. 4x and 4y are perimeters because perimeter is adding all sides of the square together. There are 4 sides to a square, therefore we get 4x and 4y.

We can use substitution method to solve.

4x-4y=24                                   [add both sides by 4y]

4x=24+4y                                  [divide both sides by 4]

x=6+y

Now that we have x, we can plug it into any equation and solve.

(6+y)²+y²=260                            [expand]

y²+12y+36+y²=260                    [combine like terms]

2y²+12y+36=260                       [subtract both sides by 36]

2y²+12y=224                              [factor out 2]

2(y²+6y)=224                             [divide both sides by 2]

y²+6y=112                                   [subtract both sides by 112]

y²+6y-112=0                                [factor equation]

(y-8)(y+14)=0                              [set each factor equal to 0 to solve]

y=8 and y=-14

We know that y=8 because (y+14)=0 gives you y=-14, but a length or area can NEVER be negative, only positive.

Now that we have y, we can plug it into any equation to find x.

4x-4(8)=24                                 [combine like terms]

4x-32=24                                   [add both sides by 32]

4x=56                                         [divide both sides by 4]

x=14

Now, we have x and y. x=14 and y=8.

Answer:

The value of f(-1) in the given equation is -10.

Step-by-step explanation:

When we see f(-1), it means that -1 is represented as our value of x. So, knowing this information, we can plug this into our given equation.

f(-1) = -3(-1)² + 2(-1) - 5

Simplify the exponent on -1.

f(-1) = -3(1) + 2(-1) - 5

Multiply -3 by 1.

f(-1) = -3 + 2(-1) - 5

Multiply 2 by -1.

f(-1) = -3 - 2 - 5

Subtract 2 from -3.

f(-1) = -5 - 5

Subtract 5 from -5.

f(-1) = -10

The function defined by [tex]f (x) = -3x^2 + 2x - 5[/tex] when x = -1 is -10

Given the function [tex]f (x) = -3x^2 + 2x - 5[/tex]

To get f(-1), we will substitute x = -1 into the function to have:

[tex]f (-1) = -3(-1)^2 + 2(-1) - 5 \\f(-1)=-3-2-5\\f(-1) =-10[/tex]

Hence the function defined by [tex]f (x) = -3x^2 + 2x - 5[/tex] when x = -1 is -10
