Answer 1

Answer:

mDE = 9

Step-by-step explanation:

mCD and mDE must add up to mCE

Step 1: Set up equation

mCD + mDE = mCE

5x + 1 + 3x + 3 = 20

Step 2: Solve for x

Combine like terms: 8x + 4 = 20Subtract 4 on both sides: 8x = 16Divide both sides by 8: x = 2

Step 3: Find mDE

mDE = 3x + 3

mDE = 3(2) + 3

mDE = 6 + 3

mDE = 9

What is the length of the hypotenuse of the triangle?

Answers

Answer:

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides. For example, if one of the other sides has a length of 3 (when squared, 9) and the other has a length of 4 (when squared, 16), then their squares add up to 25. The length of the hypotenuse is the square root of 25, that is, 5.

solve the proportion just type in the answer do not include the variables 14/8 equals x over 20​

Answers

The answer. . . . . . x=35
To solve this ratio let us use cross multiplication :-

[tex] \frac{14}{8} = \frac{x}{20} [/tex]

[tex]14 \times 20 = 8 \times x[/tex]

[tex]280 = 8x[/tex]

[tex]8x = 280[/tex]

[tex]x = \frac{280}{8} [/tex]

[tex]x = 35[/tex]

Using this let us find the proportional fractions :-

[tex] \frac{14}{8} = \frac{x}{2 0 } [/tex]

[tex] \frac{14}{8} = \frac{35}{20} [/tex]

[tex]∴the \: proportional \: fractions \:are :[/tex]

[tex] \frac{14}{8} :: \frac{35}{20} [/tex]

which property of equality is 4x-3=x+9

Answers

Answer:

Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.

5+3−2=6+2−2

This gives us a couple of properties that hold true for all equations.

The addition property of equality tells us that adding the same number to each side of an equation gives us an equivalent equation

ifa−b=c,thena−b+b=c+b,ora=c+b

The same goes with the subtraction property of equality.

ifa+b=c,thena+b−b=c−b,ora=c−b

As well as it goes for the multiplication property of equality. If you multiply each side of an equation with the same nonzero number you produce an equivalent equation.

ifab=c,andb≠0,thenab⋅b=c⋅b,ora=cb

And naturally this goes for the division property of equality as well. You can divide each side of an equation with the same nonzero number to produce an equivalent equation

ifa⋅b=c,andb≠0,thena⋅bb=cb,ora=cb

This gives us a way to change an equation to our own liking. Anything is acceptable as long as you do the same thing on both sides.

Answers

Given parameters:

 Quadratic expression:

                 x² - 6x + 7 = 0

Solve using quadratic formula;

From the equation;

  a  = 1, b = -6 and c = 7

A selective college would like to have an entering class of 1200. Because not all students who are offered admission accept, the college admits more than 1200 students. Past experience shows that about 70% of the students will accept. The college decides to admit 1500 students. Assuming that students make their decision independently, the number who accept, X, has the Bin(1500, 0.70) distribution. If this number is lower than 1200, the college will admit students from its waiting list.What is the mean of the distribution of X - that is, the expected number of students who will accept admission

Answers

Answer:

The value is [tex]\mu = 1050 [/tex]

Step-by-step explanation:

From the question we are told that

The sample size is n = 1500

The probability of a student accepting the admission is p = 0.70

Generally the mean off the distribution of X is mathematically represented as

[tex]\mu = np[/tex]

=>    [tex]\mu  =  1500 *  0.70 [/tex]

=>    [tex]\mu  =  1050 [/tex]

Step-by-step explanation:

It does not exist because the

it exist when we have

there when the value of x increasing the fractions tends to 0

so we can say that when x approaches infinity the value is 0.

Hello your question has some missing part below is the missing part

The Zagat Restaurant Survey provides food, decor, and service ratings for some of the top restaurants across the United States. For 15 restaurants located in Boston, the average price of a dinner, including one drink and tip, was $48.60. You are leaving for a business trip to Boston and will eat dinner at three of these restaurants. Your company will reimburse you for a maximum of $50 per dinner. Business associates familiar with these restaurants have told you that the meal cost at one-third of these restaurants will exceed $50. Suppose that you randomly select three of these restaurants for dinner.

Answer : 0.2637

Step-by-step explanation:

Average price of dinner including one drink and a tip in Boston = $48.60

Number of restaurants = 15

number of restaurants whose meal cost more than $50 = 1/3 * 15 = 5

Probability that None of the meals will exceed the cost covered by your company

ATTACHED BELOW is the solution

6 eggs weigh 3/4 of a pound. How much does each egg weigh?

Answers

Answer:

  1/8 lb or 2 oz

Step-by-step explanation:

You find the weight per egg by dividing the weight by the number of eggs:

  (3/4 lb)/(6 eggs) = 3/24 lb/egg = 1/8 lb/egg

A pound is 16 ounces, so 1/8 lb is 2 oz.

Each egg weighs 1/8 lb or 2 oz.
