Answer:

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251

Step-by-step explanation:

Step(i):-

Given mean of the Population = 25cm

Given standard deviation of the Population = 2.60

Let 'x' be the random variable in normal distribution

Given x=22

[tex]Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15[/tex]

Step(ii):-

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = P( Z<-1.15)

             = 1-P(Z>1.15)

             =  1-( 0.5+A(1.15)

             =  0.5 - A(1.15)

             = 0.5 - 0.3749

             = 0.1251

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251

Answer:

Selecting whether each variable is discrete or continuous:

Discrete Variables:

The number of college football games ever attended

The number of sons or daughters

The number of countries ever visited

The number of pets currently living in the household

Continuous variables:

Pounds of chocolate consumed in the past year

Shoe size

Height in inches

Step-by-step explanation:

The researcher can distinguish a discrete variable from a continuous variable by checking if the value of the variable can be counted or measured.  The researcher can count the value of a discrete variable, and she can measure the value of a continuous variable.  In other words, a discrete variable represents countable objects and a continuous variable represents measurable amounts.

Using variable concepts, we have that the discrete variables are:

The continuous variables are:

The variables that are countable, that is, discrete, are:

The ones that can assume decimal values, hence being continuous are:

Answer:

512 cube inches

Step-by-step explanation:

The radius of volleyballs is 4 inches, thus;

diameter of the balls = 2 x radius

                                   = 2 x 4

                                   = 8

The diameter of each ball is 8 inches.

Since the box has the shape of a cube, the smallest box that can hold a volleyball would have its dimensions equal to the diameter of the balls.

So that for the cube,

length = width = height = 8 inches

volume of a cube = [tex]l^{3}[/tex]

volume of the smallest box = [tex]8^{3}[/tex]

                           = 512 cube inches

The volume of the smallest box that can hold a volleyball is 512 cube inches.

Answer: 125 miles

Step-by-step explanation:

We know that 25 miles is 20% of the trip.

20% is 1/5 of 100, so that means we will multiply the number of miles driven by the denominator of the fraction.

25 × 5 = 125 miles

The answer to the question is 125 miles.

Step-by-step explanation:

Hello!

[tex]\large\boxed{2x - 8 = 7 - 3x \text{ and } 4(x - 1) = x + 5}[/tex]

We can go through each equation to solve:

1.

x + 3 = 4(x - 1) + 2

Distribute the coefficient outside of the parenthesis:

x + 3 = 4(x) + 4(-1) + 2

Simplify:

x + 3 = 4x - 4 + 2

x + 3 = 4x - 2

Subtract x from both sides:

3 = 3x - 2

Add 2 to both sides:

5 = 3x

Divide both sides by 3:

5/3 = x. This is not the answer.

2.

2x - 8 = 7 - 3x

Add 3x to both sides:

5x - 8 = 7

Add 8 to both sides:

5x = 15

Divide both sides by 5:

5x/5 = 15/5

x = 3. This is an answer.

3.

3(x + 2) = 14 - x

Distribute:

3(x) + 3(2) = 14 - x

3x + 6 = 14 - x

Add x to both sides:

4x + 6 = 14

Subtract 6 from both sides:

4x = 8

Divide both sides by 4:

4x/4 = 8/4

x = 2. This is not an answer.

4.

4(x - 1) = x + 5

Distribute:

4x - 4 = x + 5

Subtract x from both sides:

3x - 4 = 5

Add 4 to both sides:

3x = 9

Divide both sides by 3:

3x/3 = 9/3

x = 3. This is an answer.

5.

5 - 2(x + 1) = x

Distribute:

5 - 2x - 2 = x

Simplify:

3 - 2x = x

Add 2x to both sides:

3 = 3x

Divide both sides by 3:

3/3 = 3x/3

x = 1. This is not an answer.

6.

6(x - 4) = 2x

Distribute:

6x - 24 = 2x

Subtract 6x from both sides:

-24 = -4x

Divide both sides by -4:

-24/(-4) = -4x/(-4)

x = 6. This is not an answer.

Answer:

2x - 8 = 7 - 3x

4(x -1) = x + 5

Step-by-step explanation:

2) 2x - 8 = 7 - 3x

   2x + 3x - 8 = 7

       5x -  8 = 7

              5x = 7 + 8

              5x = 15

                 x = 15/5

                x = 3

4) 4(x -1) = x + 5

   4x - 4 = x + 5

4x - 4 - x = 5

     3x - 4 = 5

           3x = 5 + 4

           3x = 9

             x = 9/3

            x = 3

Answer:

x = -3

Step-by-step explanation:

2(4x + 6) = 8x + 12

3(x - 1) = 3x -3

8x + 12 = 3x - 3

5x = -15

x = -3

Answer:

x=-3

Step-by-step explanation:

2(4x+6)=3(x-1)

8x+12=3(x-1)

8x-3x+12= -3

8x-3x=-3-12

5x=-3-12

5x=-15

x=-3

Answer:

30 sec.

Step-by-step explanation:

Answer:

The perimeter of a rectangle is the sum of twice the length and twice the width. If the perimeter is at least 48 cm, then the minimum perimeter is 48 cm.

Let width = x

Let length = x + 4

Perimeter = 48

We can set an inequality for perimeter using the variables.

2x + 2(x + 4) ≥ 48

Solve for x.

2x + 2x + 8 ≥ 48

4x + 8 ≥ 48

4x ≥ 40

x ≥ 10

Substitute this value of x into the variable to get your width and length.

width = 10 cm

length = 14 cm

Answer:

[tex]\huge\boxed{1000 \ \text{cm}^3}[/tex]

Step-by-step explanation:

There are two ways we can solve this equation.

The formula provided states that the volume of a cube based on the area of one of it's faces will be [tex]a^{\frac{3}{2}}[/tex], a the area of one face. Since we know the area of one face, we can substitute that inside the equation.

[tex]100^{\frac{3}{2}}[/tex]

It's important to note that when we have a number to a fraction power, it's the same as taking the denominator root of the base to the numerator power.

So - [tex]100^{\frac{3}{2}}[/tex] becomes [tex]\sqrt{100^3}[/tex]

Therefore, the volume of this cube will be [tex]1000 \ \text{cm}^3[/tex]

We can additionally use prior knowledge to find the volume of this cube.

We know that the area of a square will be [tex]s^2[/tex], where s is the length of a side. We also know the formula to find the volume of a cube from it's side length is [tex]s^3[/tex].

Since we know that one face is 100, we can make an equation - [tex]s^2=100[/tex]

Now that we know the value of s, we can plug it into the volume formula, [tex]s^3[/tex].

So the volume is [tex]1000 \ \text{cm}^3[/tex].

Hope this helped!
