Find The Missing Values So That The Area Of The Product Is Equal To Thearea Of Its Sum.

Answers

Answer 1

On solving the provided question, we can say that here, in the equation = (2x+3y)(3y-3)=12x+3y-15. so the missing values are = 3y

What is equation?

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

here, in the equation

(2x+3y)(3y-3)=12x+3y-15

so the missing values are

3y

Scores for a civil service exam are normally distributed with a mean of 75 and a standard deviation of 6.5. what score marks the difference between the bottom 10% and the top 90%?

Answers

The lowest score you can earn and still be eligible for employment is 85.6925.

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean  and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

Top 5%.

At least the 100-5 = 95th percentile.

The 95th percentile is X when Z has a pvalue of 0.95. So X when Z = 1.645.

x-75 = 1.645*6.5

x = 85.692

Thus the lowest score you can earn and still be eligible for employment is 85.6925.

The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another

Let the side of a square be x.

So,

(A) 5.2 (B) 6.5 (C) 13.1 (D) 26.2​

Answers

Answer:

B 6.5

Step-by-step explanation:

The area of a whole circle is

a = [tex]\pi[/tex][tex]r^{2}[/tex]  A whole circle is 360 degrees.  We only have part of a circle.  We were also given the diameter and we need the radius.  The radius is half of the diameter.

a = [tex]\frac{30}{360} \pi 5^{2}[/tex]

a= 6.5 rounded.

A whole circle exists 360 degrees. The radius exists half of the diameter.

[tex]$$a = (30/360) $\pi 5^2[/tex]

a = 6.5 rounded.

The area to the nearest tenth of a square centimeter, of the sector formed by the 30° angle exists at 6.5 rounded.

How to calculate the area of a circle with diameter?

The diameter of the circle exists double the radius of the circle. Therefore the area of the circle formula utilizing the diameter exists equivalent to π/4 times the square of the diameter of the circle. The formula for the area of the circle, utilizing the diameter of the circle

π/4 × [tex]$$diameter^2[/tex].

Given: diameter of the circle = 10 cm

then the radius of the circle is half of the diameter

Radius of the circle  = 10/2 = 5 cm

Area of circle = [tex]$$\pi $r^2[/tex]

Where r be the radius of the circle

A whole circle exists 360 degrees. The radius exists half of the diameter.

[tex]$$a = (30/360) $\pi 5^2[/tex]

simplifying the above equation we get

[tex]$$a = 25$\pi$ /$12[/tex]

a = 6.5 rounded.

The area to the nearest tenth of a square centimeter, of the sector formed by the 30° angle exists at 6.5 rounded.

For a total of 9 marbles.

The probability of getting a red marble is equal to the quotient between the number of red marbles and the total, so:

P(red) = 2/9

Then the probability of getting a blue marble is equal to the quotient between the number of blue marbles and the total, but because we already took one marble, now the total is 8.

Step-by-step explanation:

let width be w then length is w + 12

the perimeter ( P) is calculated as

P = 2( width + length )

here P = 60 , then

2(w + w + 12) = 60 ( divide both sides by 2 )

2w + 12 = 30 ( subtract 12 from both sides )

2w = 18 ( divide both sides by 2 )

w = 9

You want to prove that FHG is similar to RXS by the SSS Similarity Theorem. Complete the proportion that is needed to use this theorem.

Answers

Answer:

[tex]\frac{FH}{RX} =\frac{HG}{XS} =\frac{FG}{RS}[/tex]

Step-by-step explanation:

The order of the letters matters in any similarity theorem.

When triangle FHG is similar to triangle RXS, the lengths of FH must be similar to RX.

When 2 similar lines are divided, that number is the factor by which one triangle can be dilated to match the other.

That being said, each of these proportion statements can be read as individual division expressions that equal the next division expression.

This means [tex]FH\div RX = HG\div XS = FG\div RS[/tex].

If you look at it this way, you can see that the sides you need to fill in must be the corresponding similar sides, so that you end up with the factor for the dilation of the 2 triangles.

Answers

The system of linear equations can be used to find the number of nickels, n, and the number of quarters, q, yolanda used is n + q = 28

n + q = 280.05n + 0.25q = 4

Simultaneous equation

n + q = 28

0.05n + 0.25q = 4

n = 28 - q

substitute n = 28 - q

0.05n + 0.25q = 4

0.05(28 - q) + 0.25q = 4

1.4 - 0.05q + 0.25q = 4

- 0.05q + 0.25q = 4 - 1.4

0.20q = 2.6

q = 2.6 / 0.20

q = 13

Substitute into

n + q = 28

n + 13 = 28

n = 28 - 13

n = 15
