What is the correct proportion to find 22% of 86?

Answer:

44%

Step-by-step explanation:

.44 x 125 equals 55 n

Answer:

The percentage of people who were children = 44%

Step-by-step explanation:

We need to determine the percentage of the people on the trail who are children.

so

Children percentage = 55 / 125 × 100

                                   = 0.44 × 100

                                   = 44%

Therefore, the percentage of people who were children = 44%

Answer:

b i did it

Step-by-step explanation:

Answer:

The correct answer is graph C.

Step-by-step explanation:

❌On a coordinate plane, a line goes through points (negative 3, 0) and (0, negative 3).

- the first point needs to be swapped in order to form  x-3.  

❌On a coordinate plane, a line goes through points (0, negative 1) and (1, 2).

- doesnt have a negative 3.

✔On a coordinate plane, a line goes through points (0, negative 3) and (3, 0).

- this answer has x as 0, and y as -3. which is equal to x-3.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Points on line: (1,2) (3,3)

[tex]\frac{2-3}{1-3}[/tex] = [tex]\frac{-1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

0.0214

Step-by-step explanation:

Given that :

p = 5% = 0.05

Number of trials (n) = 5

probability that the sample contains exactly two defective parts

P(x = 2)

Using the binomial probability function :

P(x = x) = nCr * p^x * (1 - p)^(n-x)

P(x = 2) = 5C2 * 0.05^2 * (0.95)^3

P(x = 2) = 5C2 * 0.05^2 * (0.95)^3

P(x = 2) = 10 * 0.0025 * 0.857375

= 0.021434375

= 0.0214

Answer:$5.80

Step-by-step explanation:

if you multiply 1.29 by 4.5 then you get 5.80500 which assuming you're talking about money rounds to $5.80

Answer:

[tex]Area = 968000cm^2[/tex]

Step-by-step explanation:

To be able to answer this question properly. I'll assume the length of the room is in meters.

So for the room, we have:

[tex]Length = 12.8m[/tex]

[tex]Breadth = 850cm[/tex]

For the bed, we have:

[tex]Length = 300cm[/tex]

[tex]Breadth = 400cm[/tex]

First, we calculate the surface area of the room.

[tex]A_1 = 12.8m * 850cm[/tex]

Convert all units to cm

[tex]A_1= 12.8*100cm * 850cm[/tex]

[tex]A_1= 1 088 000 cm^2[/tex]

Next, we calculate the area of the bed

[tex]A_2 = 300cm * 400cm[/tex]

[tex]A_2 = 120000cm^2[/tex]

The area of the space left  is the difference between A1 and A2

[tex]Area = A_1 - A_2[/tex]

[tex]Area = 1088000cm^2 - 120000cm^2[/tex]

[tex]Area = 968000cm^2[/tex]

Answer: x<5

Step-by-step explanation: Subtract 10 from both sides. Simplify  -15-10 to  -25. Divide both sides by -5. Two negatives make a positive. Simplify 25/5 to 5.

Answer:

Answer = (-4,1)

Step-by-step explanation:

Answer:

the slope is undefined

Step-by-step explanation:

slope = y2 - y1

___________

x2 - x1

slope = (-10-0) / {-4 - (-4 ) }

slope = -10 / (-4 + 4)

slope = -10 / 0

slope = undefined

note - Any number divided by zero is undefined

Answer:

Volume of cylinder = 250πm³

Step-by-step explanation:

Given:

Height h = 10 m

Radius r = 5 m

Find:

Volume

Computation:

Volume of cylinder = πr²h

Volume of cylinder = π(5)²(10)

Volume of cylinder = 250πm³

Answer:

r=144

Step-by-step explanation:

Cross multiply:

12 * 60 = r * 5

Simplifying

12 * 60 = r * 5

Multiply 12 * 60

720 = r * 5

Reorder the terms for easier multiplication:

720 = 5r

Solving

720 = 5r

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-5r' to each side of the equation.

720 + -5r = 5r + -5r

Combine like terms: 5r + -5r = 0

720 + -5r = 0

Add '-720' to each side of the equation.

720 + -720 + -5r = 0 + -720

Combine like terms: 720 + -720 = 0

0 + -5r = 0 + -720

-5r = 0 + -720

Combine like terms: 0 + -720 = -720

-5r = -720

Divide each side by '-5'.

r = 144

Simplifying

r = 144

Answer:

r=144

Step-by-step explanation:

We need to find r. To do that me must make the top numbers the same.

We'll multiply

[tex] \frac{12}{r} \times \frac{5}{5 } = \frac{60}{5r} [/tex]

[tex] \frac{5}{60} \times \frac{12}{12} = \frac{60}{720} [/tex]

Since the top numbers are equal that means the bottoms are too.

So we can create the equation:

[tex]5r = 720[/tex]

Divide each side by 5

r=144

Answer:

Remove the variable from the Model

Step-by-step explanation:

Normally, when considering which variable to keep and which one to drop when considering testing of the contribution of an individual regressor variable to the model, generally speaking we use one explanatory variable for between 10-15 observations.

Now, before we run our regression, we would need to run correlation analysis between all explanatory variables to detect if there's any multicollinearity, and also between the dependent variable and the regressors in order to determine the most important predictors to be included in the regression.

So after the analysis, for the null hypothesis not to be rejected, we will remove the variable from the Model.

Answer:

50.24 [tex]m^{2}[/tex]

Step-by-step explanation:

The formula to find the area of a circle is [tex]\pi r^{2}[/tex]. The radius of this circle is 4 because the radius is half the diameter. Since [tex]\pi[/tex] is an irrational number (whose digits goes on forever without repeating), people use use the first three numbers which are 3.14. Substitute 4 for r and 3.14 for [tex]\pi[/tex] into the formula, and you’ll get 50.24, and the answers also have the [tex]m^{2}[/tex] part too because your finding the area of a shape.

Hope this helps! :)
