There are 56 female performers in a dance recital. The ratio of men to women is 3:8. How many men are in the dance recital?

Answer:

The standard deviation = 1.9

Step-by-step explanation:

standard deviation, ρ = sqrt ( [tex]\frac{sum(x_{i} - u)^{2} }{N}[/tex])

Where u is the mean of the data, [tex]x_{i}[/tex] each given value, and N is the number of data given.

Mean, u = [tex]\frac{6+5+2+5+8}{5}[/tex]

              = 5.2

So that;

[tex](6-5.2)^{2}[/tex]  = [tex](0.8)^{2}[/tex] = 0.64

[tex](5-5.2)^{2}[/tex] = [tex](-0.2)^{2}[/tex] = 0.04

[tex](2-5.2)^{2}[/tex]  = [tex](-3.2)^{2}[/tex] = 10.24

[tex](5-5.2)^{2}[/tex] = [tex](-0.2)^{2}[/tex] = 0.04

[tex](8-5.2)^{2}[/tex] = [tex](2.8)^{2}[/tex] = 7.84

Sum = 18.8

So that;

[tex]\sqrt{\frac{18.8}{5} }[/tex]  = [tex]\sqrt{3.76}[/tex]

          = 1.9391

          = 1.9

The standard deviation of the given data is 1.9

Answer:

0.5 pounds per container.

Step-by-step explanation:

just divide 3 pound by 6 containers so it would be 3/6 which is equal to 1/2 which is the same as 0.5

There each container holds a number of pounds of flour which would be  0.5 pounds.

In mathematics, divides left-hand operands into right-hand operands in the division operation.

If three pounds of flour are divided into 6 containers so that each container holds the same number of pounds of flour, we can find out how many pounds of flour each container holds by dividing the total amount of flour by the number of containers.

We can use the following equation to find out how many pounds of flour each container holds:

pounds of flour per container = total pounds of flour / number of containers

So, using this equation:

pounds of flour per container = 3 / 6

Apply the division operation, and we get

pounds of flour per container = 0.5

Each container holds 0.5 pounds of flour.

Answer:

false. the y-intercept is -2.

Answer:

28

Step-by-step explanation:

The Distributive property uses the number outside the parenthesis and combines it (using multiplication) with the ones inside.

So, the number 7 will be multiplied with the numbers inside the parenthesis.

7(11-7)

7 × 11 = 77

7 × -7 = -49 (It will just be the same way you multiply but with a added negative sign.)

77-49=

Answer:

Measurements of this years garden are 10 meters and 6 metres.

Step-by-step explanation:

Width of a rectangular garden = 3 meters

Area of a rectangular garden = 10 square meters

Also,

Area of a rectangular garden = length × breadth

10 = length × 3

Length = [tex]\frac{10}{3}[/tex] meters

Mr. Petersons wants to make the garden three times as long and two times as wide.

New length = 3 (length) = [tex]3(\frac{10}{3} )=10[/tex] meters

New breadth = 2(width) = 2(3) = 6 meters.

Therefore,

Measurements of this years garden are 10 meters and 6 metres.

Step-by-step explanation:

Answer:

Coefficient. For example, in the term -3x, -3 serves as the coefficient of x.

The number in front of a variable or term is called a coefficient.

The coefficient represents the numerical factor by which the variable or term is multiplied. In an algebraic expression, the coefficient is the number that appears directly in front of the variable.

For example, in the expression 5x, the coefficient of x is 5. Similarly, in the expression 3y², the coefficient of y² is 3. The coefficient helps determine the magnitude or scale of the variable or term within the expression.

Therefore, the number in front of a variable or term is called a coefficient.
