Answer:

The answers to your questions are given below.

Step-by-step explanation:

x² – 24 = 10x

Using the format given in the question above, we shall determine the value of x as follow:

I. Make the equation equal to zero

x² – 24 = 10x

Rearrange

x² – 10x – 24 = 0

II. Find two numbers that multiply to __ and add to ___

Multiply the first term (i.e x²) and the last term (i.e –24). The result is –24x².

Find two factors of –24x² such that their sum will result to the 2nd term (i.e –10x). The numbers are 2x and –12x

Thus, Find two numbers that multiply to –24x² and add to –10x

III. Factored equation

x² – 10x – 24 = 0

x² + 2x – 12x – 24 = 0

x(x + 2) – 12(x + 2) = 0

(x – 12)(x + 2) = 0

Thus, the factored equation is:

(x – 12)(x + 2) = 0

IV. The solution are:

(x – 12)(x + 2) = 0

x – 12 = 0 or x + 2 = 0

x = 12 or x = –2

Thus, the solutions are x = 12 or x = –2

Answer: 1/35

Step-by-step explanation:

I just did the assignment on ck-12 and got it right.

The probability of removing 4 marbles without replacing and getting exactly 3 blue is 1/35.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

A bag contains 10 colored marbles - 4 red, 4 blue, and 2 green.

The probability of removing 4 marbles without replacing and getting exactly 3 blue.

= 1/35

Answer:

The 80% confidence interval for the mean repair cost for the washers is between $34.60 and $70.66.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 4 - 1 = 3

80% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 3 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.8}{2} = 0.9[/tex]. So we have T = 1.638

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.638\frac{22.01}{\sqrt{4}} = 18.03[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 52.63 - 18.03 = $34.60

The upper end of the interval is the sample mean added to M. So it is 52.63 + 18.03 = $70.66.

The 80% confidence interval for the mean repair cost for the washers is between $34.60 and $70.66.

Answer:

D

Step-by-step explanation:

3x * 5x = 15x^2

3x * -3 = -9x

4*5x = 20x

4 *-3 = 12

so 15x^2 +(20x -9x) -12 or 15x^2 +11x -12

Answer:

1.        42

2.       46

3.      0

Step-by-step explanation:

math

Answer:

1. x = 42

2. y = 46

3. z = 0

Step-by-step explanation:

1. 45 + x = 87

         subtract 45 from both sides

  x = 42

2. y - 31 = 15

         add 31 to both sides

  y = 46

3. 5z = 0

         divide 5 from both sides

  z = 0/5

         since any fraction with a numerator of 0 is equal to 0, we get

  z = 0
