The value of x from the equation represented by the given bar diagram is 20.

The equation is represented using the bar diagram and from the bar diagram be can observe that the equation will be the following equation mentioned below:

3.5 x + 12.5 x = 320                                        equation 1

The bar diagram represents 3.5 x + 12.5 x = 320  equation. Now we will simplify this equation and will find the value of x from this equation. The steps that need to be followed to simplify this equation are shown below;

3.5 x + 12.5 x = 320

16 x = 320

Divide both sides of equation by 16 , we will get

x = 320/16

x = 20

The value of x from the equation 3.5 x + 12.5 x = 320 is 20.

Answer:

13.27 cm

Step-by-step explanation:

I am using (xy) to mean the length of the side xy

7^2 + (xy)^2 = 15^2

49 + (xy)^2 = 225

(xy)^2 = 225-49

(xy)^2 = 176

Side (xy) = sqrt(176) = 13.2664991614 = 13.27 cm

Answer:

76 colors available

Step-by-step explanation:

Given

\(Exterior\ Colors = 14\)

\(Interior\ Colors = 5\)

\(Trims = 4\)

Required

Determine the possible combinations available

From the question, there is no distinction between the selection of external and internal color.

So:

\(Colors = 14 + 5\)

\(Colors = 19\)

The are 19 possible colors and 5 possible trims.

So, number of combination is answered using the following rule of product

\(Combination = Colors * Trims\)

\(Combination = 19 * 4\)

\(Combination = 76\)

Answer:

S₂₇ = 1188

Step-by-step explanation:

Answer:

y = -19

y = -36

Step-by-step explanation:

1) -12-2-7-y = -2

-14-7 - y = -2

- 21 - y + 21 = -2 +21

-y ÷ -1 = 19 ÷ -1

y = - 19

-24 - 2- 14 - y = -4

-26 - 14 - y = -4

-40 - y +40 = -4 + 40

-y ÷ -1= 36 ÷ -1

y = -36

Answer:

There are a total of 25 marbles in the bag.

The probability of choosing a red marble first is 8/25 since there are 8 red marbles out of 25 marbles in the bag.

Since a marble is not replaced after the first selection, there are now 24 marbles in the bag. There are still 3 blue marbles in the bag.

The probability of choosing a blue marble second, after a red marble has already been selected, is 3/24 or 1/8 since there are 3 blue marbles left out of 24 marbles in the bag.

To find the probability of both events occurring together, we multiply their individual probabilities:

8/25 x 1/8 = 1/25

Therefore, the probability that a red marble is chosen first, followed by a blue marble, is 1/25.

Regression equation correctly models the data is: y = -43.98x + 1,279.93

To determine the regression equation that correctly models the data, we can use the method of linear regression. The regression equation for a straight line is generally expressed as y = mx + b, where m is the slope and b is the y-intercept.

Using the given table, we can calculate the necessary values to determine the regression equation. Let's denote the sigma notation as Σ.

The slope (m) can be calculated using the formula:

\(m = (Σxy - (Σx)(Σy) / n(Σx^2) - (Σx)^2)\)

Plugging in the values from the table:

m =\((776,600 - (299)(12,400) / 6(18,109) - (299)^2)\)

m = (776,600 - 3,708,800 / 6(18,109) - 89,401)

m = (-2,932,200 / 66,654)

m ≈ -43.98

The y-intercept (b) can be calculated using the formula:

b = (Σy - m(Σx)) / n

Plugging in the values from the table:

b = (12,400 - (-43.98)(299)) / 6

b ≈ 1,279.93

The correct regression equation that models the data is:

y = -43.98x + 1,279.93

Out of the given options, the correct regression equation is:

y = -43.98x + 1,279.93

Step-by-step explanation:

R = 10.5

Step-by-step explanation:

Using Pythagorean theorem, we can write

(OM)^2 + 10^2 = (OR + 4)^2

Since OM = OR, let's call this segment R for brevity.

R^2 + 10^2 = (R + 4)^2

R^2 + 100 = R^2 + 8R + 16

This simplifies to

8R = 84

Answer:

If there is an even number of numbers, the median is the average of the two numbers in the middle.

Step-by-step explanation:

To find the median of any set of numbers, put them in order from smallest to greatest. If a number occurs more than once, list it more than once. The number in the middle is the median. If there is an even number of numbers, the median is the average of the two numbers in the middle. For your first example, we line them up: 3, 6, 6.

Answer:

Set them from least to greatest and remove one from each side until you find the middle number! If you're left with 2, add them both and divide by 2.

Step-by-step explanation:

Step-by-step explanation:

In order to get the answer first you figure out the type of equation. In this case this is a linear equation, y=mx+b

The B or the y-intercept/base is the first step. Here, it says a fee of 14.50 is needed for each order.

The mx part will be the .08 cents needed for each copy.

y= .08x+14.50 is the equation....

The copies needed is 40 which is the x in the situation:

y=.08(40)+14.50....

.08 * 40 is 3.2 then add the base of 14.50 which is: 17.70 all together

The simplified form of the exponential expression \(b^{n- 2}\times{b^{n-3} = b^{2n - 5}\).

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

Given, An exponential expression \(b^{n- 2}\times{b^{n-3}\).

We know, Same base multiplication is exponent addition.

Therefore,

\(b^{n- 2}\times{b^{n-3} = b^{n - 2 + n - 3}\).

\(b^{n- 2}\times{b^{n-3} = b^{2n - 5}\).

Points (-1,7) and (1,3)

Formula

m = (y2 = y1) / (x2 - x1)

y2 = 7

y1 = 3

x2 = - 1

x1 = 1

Solution

m = (7 - 3) / (-1 - 1)

m = 4 / - 2

m = - 2

Now use either one of the points to get b in y = mx + b

x = 1

y = 3

m = - 2

y = mx + b

3 = -2 (1) + b

3 = -2 + b

b = 3 + 2

Squaring the binomial ax+b:

As you can see above to square the given polynomial using the method A you get at the end the formula given in method B.

The solution set for the inequality is x < 2. Among the given options, the value that is included in the solution set is 0.

To determine which value is included in the solution set for the inequality statement -3(x-4) > 6(x-1), we need to solve the inequality for x.

Starting with the given inequality:

-3(x - 4) > 6(x - 1)

First, distribute -3 and 6 to the terms inside the parentheses:

-3x + 12 > 6x - 6

Next, combine like terms by subtracting 6x from both sides and adding 6 to both sides:

-3x - 6x > -6 - 12

-9x > -18

To isolate x, divide both sides of the inequality by -9. Remember that when dividing by a negative number, we need to reverse the inequality sign:

x < (-18) / (-9)

x < 2

Therefore, the solution set for the inequality is x < 2. Among the given options, the value that is included in the solution set is 0.
