How many 4-letter words with at least one vowel can be constructed from the letters A, B, C, D, and E? (Note that A and E are vowels, any word is valid, not just English language words, and letters may be used more than once.)

Answers

Answer:

544 words

Step-by-step explanation:

The number of 4 letter words can be constructed from ABCDE would be 5^4 = 625

The number of  4 letter words can be constructed using BCD would be 3^4 = 81

So the number of words that use at least one vowel would be  5^4 - 3^4  =  625-81 = 544

Are the grades shown in the math class below normally distributed? Explain your answer.

Answers

Since the histogram is not symmetric, the grades shown in the math class below are not normally distributed.

When does a histogram represent a normal distribution?

A histogram represents a normal distribution if it symmetric.

In this problem, we have that:

57% of the grades are on the left tail.25% of the grades are on the center.18% are on the right tail.

Since the percentages at the tails are different, the histogram is not symmetric, and  the grades shown in the math class below are not normally distributed.

The diameter of a wrecking ball used to tear down buildings is 3.5 ft. What is the volume ( to the nearest hundredth) Use 3.14 for pi and round each approximation to the nearest hundredth.

Answers

Answer:

22.44 ft

Step-by-step explanation:

The radius is equal to half of the diameter or 1.75 ft (in this case).

The volume of a sphere is defined as the equation:

V = 4/3 * pi * radius ^ 3

V = 4/3 * 3.14 * 1.75 ^ 3

V = 4/3 * 3.14 * 5.36

V = 22.44 ft

You work as an assistant for a local musical theatre group, the Main Street Theatre Company. The company is putting on a production of Les Misérables this year, and they need your help planning it.

The company's first task is to cast the lead female roles of Fantine, adult Cosette, and Éponine, and the lead male roles of Jean Valjean, Inspector Javert, and Marius. You have received headshots and resumes from 28 women and 22 men who are interested in auditioning for these parts.



A: If no one has been cast yet, how many different ways are there to cast Jean Valjean from the 22 men?

The permutation illustrates that if no one has been cast yet, the different ways that are there to cast Jean Valjean from the 22 men is 22.

How to compute the value?

The ways to cast Jean will be:

= 22!/(22 - 1)!

= 22!/21!

= 22

When Jean Valjean has already been cast, the different ways that are there to cast Inspector Javert from the remaining men will be:

= 21!/(21 - 1)!

= 21!/20!

= 21

When Jean Valjean and Inspector Javert have already been cast, the different ways that are there to cast Marius from the remaining men will be:

= 20!/(20 - 1)!

= 20!/19!

= 20

Are the expressions –0.5(3x 5) and –1.5x 2.5 equivalent? explain why or why not.

Answers

Answer:

  not equivalent; signs don't match

Step-by-step explanation:

Apparently, you want to compare the expressions ...

-0.5(3x +5)-1.5x +2.5

Distributive property

The distributive property allows you to eliminate parentheses by multiplying each term inside parentheses by the factor outside.

Application

When we do that to the first expression, we get ...

  -0.5(3x +5) = (-0.5)(3x) +(-0.5)(5) = -1.5x -2.5

Note that the signs of the terms inside parentheses are the same, and the signs of the terms after removing parentheses are the same. (Both terms have their signs changed by the negative factor multiplying the parentheses.)

The expanded expression -1.5x -2.5 is not equivalent to -1.5x +2.5, which has terms of different signs.

The area of the right triangle shown is 24 square feet. Which equations can be used to find the lengths of the legs of the triangle? Select three options. 0.5(x)(x + 2) = 24 x(x + 2) = 24 x2 + 2x – 24 = 0 x2 + 2x – 48 = 0 x2 + (x + 2)2 = 100

Answers

The equations to calculate the legs are 0.5(x)(x + 2) = 24, x^2 + 2x - 48 = 0 and x^2 + (x + 2)^2 = 100

How to determine the legs of the triangle?

The complete question is in the attached image

The given parameters are:

Area = 24

Legs = x and x + 2

The area of the triangle is calculated as:

Area = 0.5 * Base * Height

This gives

0.5 * x * (x + 2) = 24

So, we have:

0.5(x)(x + 2) = 24

Divide through by 0.5

(x)(x + 2) = 48

Expand

x^2 + 2x = 48

Subtract 48 from both side

x^2 + 2x - 48 = 0

Hence, the equations to calculate the legs are 0.5(x)(x + 2) = 24, x^2 + 2x - 48 = 0 and x^2 + (x + 2)^2 = 100

Write an equation of a circle with the given center and radius

Answers

The equation of the circle is (x + 7)² + (y + 6)² = 4 if the center and radius are (-7,-6) and 2 respectively.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have center of the circle(h, k) = (-7, -6)

The radius of the circle r = 2

The standard form of a circle:

(x - h)² + (y - k)² = r²

(x - (-7))² + (y - (-6))² = 2²

(x + 7)² + (y + 6)² = 4

Thus, the equation of the circle is (x + 7)² + (y + 6)² = 4 if the center and radius are (-7,-6) and 2 respectively.

WHY IS THAT THE LINEAR EQUATION

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y

WHAT IS THE NONLINEAR EQUATION

Y = x(3x+2)

WHY IS THAT THE LINEAR EQUATION

A nonlinear function has more than one independent variable. The independent variable is x.

y= x(3x-2) is non linear equation.

y= x/3 + 2  is linear equation.

y= 3 -2x  is linear equation.

What is Linear Equation?

Linear equations are the equations of degree 1.

It is the equation for the straight line.

The standard form of linear equation is ax+by+c =0, where a ≠ 0 and b ≠ 0.

We know that the linear equation have highest degree 1.

First, y= x(3x-2)

y= 3x² -2x

Here, the highest degree is 2 which is non linear equation.
