For many years businesses have struggled with the rising cost of health care. But recently, the increases have slowed due to less inflation in health care prices and employees paying for a larger portion of health care benefits. A recent Mercer survey showed that of U.S. employers were likely to require higher employee contributions for health care coverage in 2009. Suppose the survey was based on a sample of companies. Compute the margin of error and a confidence interval for the proportion of companies likely to require higher employee contributions for health care coverage in 2009. The margin of error: (to 4 decimals) The confidence interval: ( , ) (to 4 decimals)

Step 2: Simplify

Answer:

Step-by-step explanation:

[tex]3)\frac{5x}{2}+125 = 180\\\\\frac{5x}{2}=180-125\\\\\frac{5x}{2}=55\\\\ 5x = 55*2\\\\ x =\frac{55*2}{5}\\\\ x = 11*2 = 22[/tex]

4) 3x+ 42 + 90= 180

3x + 132 = 180

        3x = 180 -132

        3x = 48

          x = 48/3

         x = 16

Answer:

6.4 miles

Step-by-step explanation:

5^2 + 4^2 = d^2

25 + 16 = d^2 = 41

d = 6.40 miles

The nearest tenth of a mile from your starting point is 6.4.

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

To round a number to the nearest tenth, we need to look to the right of the tenths place, which is the hundredths place. If the digit in the hundredths place is 5 or greater than 5, we need to add one to the digit in the tenths place. If it is 4 or less than 4, the tenths place digit remains the same. All the digits to the right of the tenths place should be changed to 0. That means, while rounding off a number to the nearest tenth, we will stop the rounding at the tenths place.

According to the question

If you drive 5 miles east and then 4 miles south

We have to find the nearest tenth of a mile from your starting point

From the diagram, we have to use Pythagoras theorem

D = [tex]\sqrt{4^{2} +5^{2} }[/tex]

D = [tex]\sqrt{16+25}[/tex]

D = [tex]\sqrt{41}[/tex]

D = 6.40312

Round 6.40312 to the required nearest tenth

D = 6.4

Hence, The nearest tenth of a mile from your starting point is 6.4.

Answer:

The coefficient of the term 13a is, 13

Step-by-step explanation:

Coefficient term are the numbers that multiply the variables or letters

In the given expression:

13a means 13 times a , and a is the variable,

so 13 is the coefficient .

6b means 6 times b , and b is the variable ,

so 6 is the coefficient .

therefore, the coefficient of the term 13a in the given expression is, 13.

Answer: (2x - 1)(3x - 4)

(split -11x as -8x and -3x)

Step-by-step explanation:

I am assuming that it is actually 6x^2 - 11x + 4

To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)

-8, -3 works

(6x^2 - 8x) + (-3x + 4)

2x(3x - 4) + -1(3x - 4)

Answer:

[tex]y = -2x -1[/tex]

Step-by-step explanation:

Given

Passes through: (0, -1)

Parallel to: y = -2x + 7

Required

Determine the line equation

If the line is parallel to y = -2x + 7, then it has the same slope as y = -2x + 7.

For an equation of form: [tex]y = mx + b[/tex]

The slope is m

By comparison:

[tex]m = -2[/tex]

So, the slope of the extorted is -2.

The equation is then calculated using:

[tex]y = m(x - x_1)+ y_1[/tex]

[tex]y = -2(x - 0)-1[/tex]

[tex]y = -2(x )-1[/tex]

[tex]y = -2x -1[/tex]

Answer:

5

Step-by-step explanation:

Subtract 7-2=5.

Answer:

1) Function

2) Set Notation

3) Domains: {-4, -2, -1, 1, 3, 4}

4) Ranges: {-3, -2, 0, 2, 3}

Step-by-step explanation:

1) This is a function because the x-values are NOT repeated, and it passes the vertical line test.

2) This is a set notation because it has the symbol --> {    } and it is "help define the elements of a set." You can search up "set notation" and you would get the idea. However, this is not an inequality because in inequality you would have, ex: x < 4 ≤ x

3) Domains mean the x-intercept. Remember to list domains from least to greatest!

4) Range means y-intercept. Remember to list the ranges from least to greatest! If a range is repeated then you do NOT need to re-write that number again.

Answer: B) No; the remainder is 234, so (x+3) is not a factor.

===============================================================

Explanation:

We'll use the remainder theorem. That theorem says if we divide p(x) over (x-k), then the remainder is p(k). A special case of this theorem says that if we get 0 as the remainder, then (x-k) is a factor of p(x).

We're dividing f(x) over (x+3) which means that k = -3. Think of x+3 as x-(-3) so you can match it up with the form x-k.

To find the remainder of f(x)/(x+3), we need to compute f(-3).

Plug x = -3 into the f(x) function to get...

f(x) = 4x^3 + 11x^2 - 75x + 18

f(-3) = 4(-3)^3 + 11(-3)^2 - 75(-3) + 18

f(-3) = 234

The remainder is 234, which is isn't zero, so (x+3) is not a factor of f(x).

Answer:

No; the remainder is 0 so (x + 3) is not a factor
