In parallelogram wxyz, what is cy? 11 ft 15 ft 21 ft 23 ft
The CY in the given Parallelogram WXYZ is 15 ft.
A parallelogram is defined as, "A geometrical figure whose sides are parallel to each other. "
In the given Parallelogram WXYZ, the length of the sides is not given. Although, the length of the two diagonal sides is given which are CY and CW with a variable x. The following are the values of these two diagonals:
CY = (2x - 7) ft .....(1)
CW = (x + 4) ft ......(2)
In this given question, we need to find the value of CY. So, we can find the value of CY by finding the value of variable x.
To find the value of x, we follow the theorem:
"In the parallelogram, The diagonals bisect each other"
We get that,
CY = CW ......(3)
By putting the value equation (1) and (2) in equation (3), we get
2x - 7 = x + 4 ......(1)
By subtracting 'x' and adding '7' on both sides of the equation.
x = 11,
So we get,
x = 11.
By putting the value of 'x' in equation (1), we get:
CY = 2(11) - 7 = 11 - 7
CY = 4.
Hence, the value of CY is 4.

What is ANOVA ?
Analysis of variance (ANOVA) is a statistical technique for examining variations in means. It consists of a number of statistical models and the estimating techniques they require. The statistician Ronald Fisher is credited with creating the ANOVA. According to the law of total variance, which is the foundation of ANOVA, the observed variance in a given variable is divided into components that can be attributed to various causes of variation. ANOVA generalizes the t-test beyond two means by offering a straightforward statistical test for the equality of two or more population means. In other words, the ANOVA is employed to compare two or more means.
Therefore, the correct answer is analysis of variance.

Shera is building a cabinet. She is making wooden braces for the corners of the cabinet. Find the surface area of each brace.
The surface area of each brace of the cabinet is 30 square inches
What is the surface area of each brace?length = 3 inWidth = 3 inHeight = 1 inSurface area of the first brace = 2 (lh +wh + lw )
= 2{(3×1) + (3 × 1) + (3 × 3)}
= 2(3 + 3 + 9)
= 2(15)
= 30 square inches
Surface area of the second brace = 2 (lh +wh + lw)
= 2{(3×1) + (3 × 1) + (3 × 3)}
= 2(3 + 3 + 9)
= 2(15)
= 30 square inches
Total surface area of the cabinet = Surface area of the first brace + Surface area of the second brace

Use a Riemann sum with 4 rectangles of equal width to approximate the area between y=3x^(2)+1 and the x-axis on the interval -1,5. Use the left -hand endpoint of each subinterval.
The approximate area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 is 136.6875.
We can approximate the area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 using a Riemann sum with 4 rectangles of equal width. The left-hand endpoint of each subinterval will be used.
The width of each rectangle is the length of the interval (5-(-1)) divided by the number of rectangles (4). Therefore, the width of each rectangle is
(5-(-1))/4 = 6/4 = 1.5.
Since we are using the left-hand endpoint of each subinterval, the x-values of the left-hand endpoints of the rectangles are
-1, -1+1.5
-1+1.5+1.5
-1+1.5+1.5+1.5 = -1+4.5=3.5
The height of each rectangle is determined by the value of y at the corresponding x-value.
Therefore, the heights of the rectangles are
3(-1)^2+1=2
3(-1+1.5)^2+1=7.125
3(3.5)^2+1=35.125
3(3.5+1.5)^2+1=46.875
The area of each rectangle is the product of its width and height, so the areas of the rectangles are
2*1.5=3
7.125*1.5=10.6875
35.125*1.5=52.6875
46.875*1.5=70.3125.
Therefore, the approximate area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 is 136.6875.

Using the inverse proportion formula, the value of the second quantity y in the question is (D) 27.
What is inverse proportion?One kind of proportionality relationship is inverse proportion.
If two quantities are inversely related, one will increase while the other will decrease.
Building a wall would be an example of an inverse proportion in action.
On the other hand, in indirect or inverse proportion, if one quantity rises, the other one falls, and vice versa.
So, the value of the second quantity will be:
The formula for inverse proportion:
y = k/x ...(1)
Pur x = 15 and y = 18 in (1) as follows:
15 = k/15
× 15 on both sides:
15 × 15 = k/15 × 15
k = 270
Now, obtain y as follows using the same process:
Let, x = 10 and k = 270:
y = k/x
y = 270/10
y = 27

Probability:
In math, probability means the possibility of favorable outcome.
Given,
License plates in a country far away consist of 2 letters followed by 4 digits (0-9). if the only restriction is that plates can not have the same digit 4 consecutive times,
Here we need to find how many plates are possible.
Here we have given that, A license plate composed of 2 letters followed by 4 digits.
The first step is considering the letters in the plate.
Here we know that, the plate consists of 2 letters.
And in alphabets, we have 26 letters which start from A to Z.
Therefore, we can choose 2 letters from 26 letters in 26² ways.
Now, we considering the digits in the plate.
Here the plate consists of 4 digits.
And we have 10 digits which starts from 0 to 9.
Now we can choose 4 digits from 10 digits in 10⁴ ways.

The final cost for Paul's ping pong table will be;
⇒ $296.8
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The original price of ping pong table = $350
And, He uses a coupon code to get a 20% discount off of the original price. He is then charged a 6% tax on the discounted price.
Now,
Since, The original price of ping pong table = $350
And, He uses a coupon code to get a 20% discount off of the original price.
Hence, The discounted price = 20% of $350
= 20/100 × 350
= $70
So, The price of ping pong table = $350 - $70
= $280
And, He is then charged a 6% tax on the discounted price.
So, We get;
The tax price = 6% of $280
= 6/100 × $280
= $16.8
Thus, The final price for Paul's ping pong table = $280 + $16.8
= $296.8

Suppose the mean gmat score is 550 with a standard deviation of 100. Hayden takes the gmat and is told his z-score is 2. 5. Interpret the meaning of a z-score in this context.
a 2.5 z score is that, Hayden's score is 2.5 standard deviations below the 550
z-scores are used to describe normal distributions
The interpretation of a 2.5 z score is that, Hayden's score is 2.5 standard deviations below the 550
How to interpret the z-scores
The z-score is given as:
z = 2.5
The mean and the standard deviation are:
Mean = 550
Standard deviation = 100
A z-score is the number of standard deviations above or below the mean.

The probability having of 3 boys and 4 girls is 33 or 0.33
what is probability?
The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
solution:
Assuming 50/50 chance on boy/girl we see following outcome:
(1/2^7).
Since there is only one way you can have 3 girls, followed by 4 boys.
If you would tell the boys apart, and the girls, for instance by their names, the probability would be:
6 * (1/2)^3 *(1/2)^4 * 24.
6 Times because the girls would then have 6 orders of having been born.
24 Times because then the boys would have 24 orders of having been born.
