if x=2+ root 3 then find the value of (x-1/x)^3

HELP ASAP

**Answer:**

*10 and ten-elevenths*

**Step-by-step explanation:**

x = 2 + _/3

(x-1/x)^3

(2+_/3)^3 - (1÷2+_/3)^3

= (8 + 3) - 1 ÷ (8 + 3)

= 11 - 1/11

Find the slope of f(x)=5x-4

**Answer:**

5

**Step-by-step explanation:**

**Answer:**

slope, m = 5

**Step-by-step explanation:**

Recall that the slope-intercept form of a linear equation can be written:

y = mx + b or f(x) = mx + b

where m is the slope of the line.

in our case, we are given

f(x) = 5x - 4

if we compare this with the general equations above, we can see that

slope = m = 5

hence the slope is 5

According to the US Bureau of Labor statistics, the average weekly earning of a production worker in 1997 were $424.5. Suppose a labor researcher wants to test to determine whether this figure is still accurate today .The researcher randomly selected 54 production workers from across the United States and obtained a representative earning statement for one week from each. The resulting sample average is $432.69. Assuming population Standard deviation is 33.90. and a 5% level of significance, To determine whether the mean weekly earnings of the production worker have changed.

Required:

To determine whether the mean weekly earnings of the production worker have changed, what would be the value of test statistics?

Answer:

test statistic is 1.775

Step-by-step explanation:

Bar x = 432.69

Standard deviation sd = 33.90

N = 54 production workers

Null hypothesis:

H0: μ = 424.5

Alternate hypothesis

H1: μ not equal to 424.5

Test statistic

= 432.69-424.5/sd/√n

= 8.19/33.9/√54

= 8.19/33.9/7.348

8.19/4.6135

= 1.7752

This is the value of our test statistic

When we test this with level of significance 0.05

Critical value z = 1.96

So we conclude that we do not have enough evidence to reject null hypothesis so we accept null and say mean weekly earnings have not changed

A researcher is exploring the notion that there is an economy of scale in raising children. While having one child might add to a family's financial stress, the second or third one might not be as "expensive" since they would already be sharing one roof, could share clothing, etc. The researcher has access to a large community of parents where 15% have one child under 18 in their home, 65% of parents have two children, and 20% of parents have three or more children. Rounded to the nearest whole number, the probability that any given family who is selected has two or more children at home is ________ %?

**Answer:**

The probability that any given family who is selected has two or more children at home is **85%**.

**Step-by-step explanation:**

The information provided is as follows:

Number of Children Probability

1 0.15

2 0.65

> 3 0.20

Compute the probability that any given family who is selected has two or more children at home as follows:

P (At least 2 Children) = P (2 children) + P (More than 3 children)

= 0.65 + 0.20

= 0.85

Thus, the probability that any given family who is selected has two or more children at home is **85%**.

which equation represents a line which is parallel to the line x-3y=15?

**Step-by-step explanation:**

Two lines that are parallel have the same slope. If we make [tex]x - 3y = 15[/tex] in to slope-intercept form it'll be like this:

[tex]x - 3y = 15 \\ -3y = 15 - x \\ y = \frac{15 - x}{-3} \\ y = \frac{1}{3}x - 5[/tex]

Now we know [tex]y = \frac{1}{3}x - 5\\[/tex] as its slope-intercept form we can see the slope is [tex]\frac{1} {3}\\[/tex].

[tex]y = \frac{1}{3}x + 4\\[/tex] has the same slope as [tex]y = \frac{1}{3}x - 5\\[/tex] so they are both parallel.

Answer:[tex]y = \frac{1}{3}x + 4\\[/tex]

A **percentage **is a way to describe a part of a **whole**. The **amount **paid by **Marta **for the cookbook is** $7.80.**

A **percentage **is a way to describe a part of a whole. such as the fraction ¼ can be described as **0.25 **which is equal to **25%.**

To convert a fraction to a percentage, **convert **the fraction to decimal form and then multiply by 100 with the** '%' symbol.**

As it is given that the **original **price of the cookbook was **$13, **Marta bought it for **40% off.** Therefore, Marta only paid** 60%** of the **original cost,**

[tex]\text{Amount paid by Marta} = \text{60\% of the original cost}\\\\\text{Amount paid by Marta} = \dfrac{60}{100} \times \$13\\\\\text{Amount paid by Marta} = \$7.8[/tex]

Is the expression 6+3=9 an equation? Explain.

**Answer:**

No, 6+3=9 is not an equation.

**Step-by-step explanation:**

The reason as to why this is not an equation is because an equation is a statement that asserts the equality of two expressions, which are connected by the equal sign. And 6+3=9 does not in fact connect two separate expressions.

Which order pairs are solutions to the equation 4x+2y=4

**Answer:**

Slope=2.000/4.000

−2.000x−intercept= 22

=1y−intercept= 12

=**2.00000**

**Step-by-step explanation:**

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

4*x+2*y-(4)=0

Pull out like factors :

4x + 2y - 4 = 2 • (2x + y - 2)

Solve : 2 = 0

This equation has no solution.

A non-zero constant never equals zero.

Solve 2x+y-2 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2x+y-2 = 0 and calculate its properties

Notice that when x = 0 the value of y is 2/1 so this line "cuts" the y axis at y= 2.00000

y-intercept = 2/1 = 2.00000

When y = 0 the value of x is 1/1 Our line therefore "cuts" the x axis at x= 1.00000

x-intercept = 2/2 = 1

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 2.000 and for x=2.000, the value of y is -2.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -2.000 - 2.000 = -4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -4.000/2.000 = -2.000

A and B are complementary angles. If mA = (2x + 30)° and mB = (7x – 3), then find the measure of B.

**Answer:**

mB=46

**Step-by-step explanation:**

2x+30+7x-3=90

Combine like terms

9x+27=90

Subtract by 27 on both sides

9x=63

Divide by 9 on both sides

x=7

mB=(7x-3)

Substitute 7 for x

mB= 7(7)-3

mB= 49-3

mB=46

**Answer:**

The measure of B is 46°

**Step-by-step explanation:**

To solve this equation, you need to add the two equations, and set them equal to 90° since they are **complementary angles**

2x+30+7x-3=90

You also need to add like terms, so 2x+7x and 30+-3, or 30-3

9x+27=90

Then you need to isolate the variable by subtracting 27 from both sides

9x+27-27=90-27

=

9x=63

Then you need to divide both sides by 9 to get x=7

Since we know what x is, we plug x into the equation (7x-3) and we will now have 7(7)-3.

To solve this, we multiply 7 and 7, and subtract 3 to get 46.

So the answer is mB=46
