I'm pretty sure it's -625
Step-by-step explanation:
-5 to the fourth power is written like this:
-(5^4)
So all you need to do is 5x5x5x5
5x5 equals 25 so then all you have to do is 25x25
After solving it out on a piece of paper, it should be 625
But because they should be in parenthesis, all you need to do is add the negative symbol to 625 which gives you the answer of -625

a) X'Y' + X'Y + XY simplifies to X' + Y.

Complement of the functions:
a) Complement is W' + X' + YZ.
b) Complement is (A' + B + C)(A'B' + C' + A'B).
a) To prove X'Y' + X'Y + XY = X' + Y, we can use Boolean algebra identities:
X'Y' + X'Y + XY
= Y'(X' + X) + XY(Distributive Law)
= Y' + XY(X + X' = 1)
= X' + Y(Commutative Law)
Therefore, X'Y' + X'Y + XY simplifies to X' + Y.
b) To prove A'BC' + ABC' + BC'D = BC', we can simplify the expression using Boolean algebra:
A'BC' + ABC' + BC'D
= BC'(A' + A) + BC'D (Distributive Law)
= BC' + BC'D(A + A' = 1)
= BC'(BC' + BC'D = BC' + BC'(1) = BC')
Hence, A'BC' + ABC' + BC'D simplifies to BC'.

The box plot represents the data set 2, 4, 6, 8, 10, 12 is option (a) A box-and-whisker plot. The number line goes from 1 to 10. The whiskers range from 1 to 9, and the box ranges from 3 to 8. A line divides the box at 7. 5.
A box-and-whisker plot is a graphical representation of a data set that displays the distribution of the data, as well as its quartiles and any outliers. The plot is made up of a rectangular box, which represents the middle 50% of the data, with a line in the box representing the median. Two lines, called whiskers, extend from the box to represent the range of the data outside of the box, excluding any outliers. Outliers are any values that fall outside of the whiskers.
In the given options, the box-and-whisker plot that represents the data set 2, 4, 6, 8, 10, 12 is the one that has a box ranging from 4 to 10, with a median line dividing the box at 7. This means that 50% of the data falls between 4 and 10, with the median value being 7. The whiskers range from 2 to 12, indicating that the data set has a minimum value of 2 and a maximum value of 12.
Therefore, the correct option is (a) A box-and-whisker plot. The number line goes from 0 to 12. The whiskers range from 2 to 12, and the box ranges from 4 to 10. A line divides the box at 7.

Find the variance of X.
Answers
(a) The mean of X is infinite, which means that X does not have a finite mean. (b) The variance of X is undefined.
To find the variance of the random variable X, we first need to find the mean of X. The mean (μ) of a continuous random variable can be calculated using the formula:
μ = ∫(x * f(x)) dx
where f(x) is the probability density function of X.
In this case, the probability density function f(x) is given as 52(x+2) for x greater than or equal to 0, and 0 elsewhere.
(a) First, let's find the mean (μ):
μ = ∫(x * 52(x+2)) dx
= ∫(52x^2 + 104x) dx
= 52 ∫(x^2 + 2x) dx
= 52 * [ (1/3)x^3 + x^2 ] + C
= (52/3)x^3 + 52x^2 + C
Now, to find the limits of integration, we need to know the range of the random variable X. Since the given density function f(x) is defined only for x greater than or equal to 0, the range of X is [0, ∞). Therefore, we can set the lower limit of integration to 0.
μ = (52/3)(x^3) + 52(x^2) | from 0 to ∞
= (∞) - (52/3)(0^3) - 52(0^2) - [(52/3)(0^3) + 52(0^2)]
= ∞
The mean of X is infinite, which means that X does not have a finite mean.
(b) Since the variance (σ^2) is defined as the average of the squared deviations from the mean, and the mean is infinite in this case, we cannot calculate the variance of X.
Therefore, the variance of X is undefined.

2. en un taller fueron reparados durante un mes 120 vehículos entre automóviles y motos. el número de ruedas de los vehículosreparados fue de 336 exactamente. ¿cuántas motos se repararon?
Answers
36 motorcycles were repaired during the month.
To solve this problem, we can use the formula for the total number of wheels of a vehicle, which is equal to the number of vehicles multiplied by the number of wheels per vehicle. In this case, the number of wheels per vehicle is 4 since both autos and motorcycles have 4 wheels each. This formula can be expressed as: Wheels = Vehicles × Wheels per Vehicle.
We can substitute the given values of the total number of wheels (336) and the number of wheels per vehicle (4) into the formula, and solve for the number of vehicles (V): Wheels = Vehicles × Wheels per Vehicle → 336 = Vehicles × 4 → Vehicles = 336 ÷ 4 → Vehicles = 84.
Since we know that both autos and motorcycles were repaired, and the total number of vehicles was 84, we can use the information that 120 vehicles were repaired to solve for the number of motorcycles (M) that were repaired.
If the total number of vehicles was 84, and 120 vehicles were repaired, then the number of motorcycles that were repaired must be equal to the difference between the total number of vehicles and the total number of autos, which is 120 - 84 = 36.
Therefore, 36 motorcycles were repaired during the month.

The value of c for which the considered trinomial becomes perfect square trinomial is: 20 or -20
What are perfect squares trinomials?They are those expressions which are found by squaring binomial expressions.
Since the given trinomials are with degree 2, thus, if they are perfect square, the binomial which was used to make them must be linear.
Let the binomial term was ax + b(a linear expression is always writable in this form where a and b are constants and m is a variable), then we will obtain:
\((ax + b)^2 = a^2x^2 + b^2 + 2abx\)
Comparing this expression with the expression we're provided with:

By using the sum or difference formula of cosine to solve cos(525°) we get cos(525°) = -0.465
The formula to find the value of cos(A ± B) is given as,
cos(A + B) = cosA cosB − sinA sinBcos(A − B) = cosA cosB + sinA sinB
Here, A = 450° and B = 75°
We can write 525° as the sum of 450° and 75°.
Therefore,cos(525°) = cos(450° + 75°)
Now, we can apply the formula for cos(A + B) and solve it.
cos(A + B) = cosA cosB − sinA sinBcos(450° + 75°) = cos450° cos75° − sin450° sin75°= 0.707 × 0.259 − 0.707 × 0.966= -0.465
Substituting the values in the above equation, we get

(note: some answers are rounded to two decimal places.)
Answers
We can start by creating a table to organize the information:
Likes Chocolate (c) Does Not Like Chocolate (~c) Total
Likes Sprinkles (s) 0.25 0.40
Does Not Like Sprinkles (~s) 0.60
Total 0.70 0.30 1.00
We are given that 40% of friends like sprinkles, so we can fill in that cell of the table. We are also given that 25% of friends who like chocolate also like sprinkles, so we can fill in the cell for likes chocolate and likes sprinkles as 0.25.
To find the proportion of friends who like sprinkles and chocolate, we need to divide the number of friends who like both by the total number of friends who like sprinkles:
proportion = likes chocolate and sprinkles / likes sprinkles
proportion = 0.25 / 0.40
proportion = 0.625
So, approximately 62.5% of friends who like sprinkles also like chocolate.
