Answer:

She should add 10x to both sides

Step-by-step explanation:

Answer:

Step-by-step explanation:

x² - 10x - 2 = 0   {Add 2 to both sides}

            +2 = +2

x² - 10x     = 2

Now to find what to add both sides, divide the co-efficient of x by 2

10/2 = 5

Add 5² to both sides

x² - 10x + 25 = 5²

(x - 5)² = 5²

Take square root both sides,

x - 5 = ± 5

x- 5 = 5   ;   x - 5 = -5

  x = 5+5 ;      x = -5 + 5

  x = 10    ;      x = 0

The lowest point in a business cycle, which follows a period of economic

decline, is called a trough. Therefore, option A is the correct answer.

A prolonged period of weak or negative real GDP (output) growth that is accompanied by a noticeably higher unemployment rate is known as a recession. During a recession, a lot of other economic activity indices are similarly weak.

Trough: This refers to the stage of the business cycle when economic activity is at its lowest point.

Expansion: It denotes the period following a dip when overall demand rises. It leads to a rise in output and a decrease in unemployment.

In the business cycle, expansions and contractions alternate (also called recessions).

Recessions frequently begin at the business cycle's high, when an expansion comes to an end, and finish at its trough, when the following expansion starts.

Therefore, option A is the correct answer.

Step-by-step explanation:

Equate the values on the left to like values on the right side

4x + 2i = 8 + yi , then

4x = 8 ⇒ x = 2

y = 2

Then x = 2, y = 2

5

- 10x + 12i = 20 + 3yi , then

- 10x = 20 ⇒ x = - 2

3y = 12 ⇒ y = 4

Then x = - 2, y = 4

6

2x - yi = 14 + 12i , then

2x = 14 ⇒ x = 7

- y = 12 ⇒ y = - 12

Then x = 7, y = - 12

7

54 - [tex]\frac{1}{7}[/tex] yi = 9x - 4i , then

9x = 54 ⇒ x = 6

- [tex]\frac{1}{7}[/tex] y = - 4 ( multiply both sides by - 7 )

y = 28

Then x = 6, y = 28

Answer:

4x + 2i = 8 + yi , then

4x = 8 ⇒ x = 2

y = 2

Then x = 2, y = 2

Answer:

24/35

Step-by-step explanation:

Answer:

24/35

Step-by-step explanation:

turn 1 1/7 into a mixed number

1 1/7=8/7

multiply the numerator and the denominator of 8/7 and 3/5 to get 24/35

Formula for circumference is C= πd, meaning pi multiplied by diameter. I will complete the question using both 3.14 for pi, and the pi key on the calculator, as I am not sure what the rules are for your mathematics class.

Formula C=πd, where diameter (given: 56) is 56 and pi is 3.14.

C=πd

  = 3.14 x 56

  =175.84

∴ The circumference of the wheel is about 175.8cm.

To find how much distance covered in 100 revolutions, we must multiply the distance covered in one revolution by 100.

175.84 x 100= 17584

The question does not ask to convert to meters or kilometers so I may leave it like this.

If you are told otherwise, follow the rules for converting.

∴ The distance covered in 100 revolutions is 17,584cm.

Formula C=πd where d equals 56 and pi is the full value of pi (3.1415926....)

C=πd

 = π x 56

 =175.929

As you can see, we get a more accurate answer, but again, it is all up to your class rules.

∴ About 175.93 cm circumference

Revolutions:

175.93 x 100 = 17593

∴ About 17, 593cm.

Answer:

By the Central Limit Theorem, it is approximately normal with mean 0.29 and standard deviation 0.0596

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree.

This means that [tex]p = 0.29[/tex]

You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree.

This means that [tex]n = 58[/tex]

Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.

By the Central Limit Theorem, it is approximately normal with mean [tex]\mu = p = 0.29[/tex] and the standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.29*0.71}{58}} = 0.0596[/tex]

Your diagram shows the short side is 15, so the other sides can be found by multiplying the above ratio numbers by 15.
