Choose the correct order of steps to solve the equation x/2+5=9 ? I. Multiply both sides by 2 II. Add 5 to both sides III. Divide both sides by 2 IV. Subtract 5 from both sides

Answers

Answer 1
Answer:

subtract 5 from both sides


Answer 2
Answer:

The steps you take to solve an equation of this sort are informed by the Order of Operations. Look at what operations are performed on the variable when you evaluate this equation. They are

• x is divided by 2

• 5 is added to the quotient


To solve for x, you "undo" these operations in reverse order. To "undo" addition, you perform subtraction. Here, you (IV.) subtract 5 from both sides as the first step of your solution.


Then you undo the division by 2. To "undo" division, you perform multiplication. Here, you (I.) multiply both sides by 2 as the second step of your solution.



In summary, the order of steps you would take to solve this equation is

... IV

... I


_____

x/2 + 5 = 9

x/2 = 4 . . . . . . . . subtract 5

x = 8 . . . . . . . . . . multiply by 2


Note that in our description of the operation we performed, we simply say "subtract 5" because the properties of equality require that you do that to both sides of the equation.

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 survey showed that 62% of employers are likely to require higher employee contributions for health care coverage this year relative to last year. Suppose the survey was based on a sample of 800 companies likely to require higher employee contributions for health care coverage this year relative to last year. At 95% confidence, compute the margin of error for the proportion of companies likely to require higher employee contributions for health care coverage. (Round your answer to four decimal places.) Compute a 95% confidence interval for the proportion of companies likely to require higher employee contributions for health care coverage. (Round your answers to four decimal places.)

Answers

Answer:

95% confidence interval for the proportion of companies likely to require higher employee contributions for health care coverage.

(0.5868 , 0.6532)

Step-by-step explanation:

Step(i):-

Given the survey was based on a sample of 800 companies

Given size 'n'  = 800

A recent survey showed that 62% of employers are likely to require higher employee contributions for health care coverage this year relative to last year

sample proportion

                                p⁻ = 0.62

Step(ii):-

The margin of error for the proportion of companies likely to require higher employee contributions for health care coverage.

M.E= Z_(0.05)  \sqrt{(p^(-) (1-p^(-)) )/(n) }

M.E= 1.96\sqrt{(0.62 (1-0.62 )/(800) }

M.E  = 0.017 X 1.96

M.E = 0.03

Step(iii):-

95% confidence interval for the proportion of companies likely to require higher employee contributions for health care coverage.

(p^(-) - Z_(0.05)  \sqrt{(p^(-) (1-p^(-)) )/(n) } , p^(-) +Z_(0.05)  \sqrt{(p^(-) (1-p^(-)) )/(n) })

(0.62 - 1.96\sqrt{(0.62 (1-0.62 )/(800) } ,0.62+1.96\sqrt{(0.62 (1-0.62 )/(800) }

( 0.62 - 0.0332 , 0.62+0.0332)

(0.5868 , 0.6532)

Final answer:

The margin of error for the proportion of companies likely to require higher employee contributions for health care coverage is approximately 0.0245. The 95% confidence interval for the proportion of companies likely to require higher employee contributions is (0.5955, 0.6445).

Explanation:

To compute the margin of error for the proportion of companies likely to require higher employee contributions for health care coverage, we can use the formula:

Margin of error = Z * sqrt((p * (1-p)) / n)

where Z is the Z-score corresponding to the desired confidence level (95% in this case), p is the proportion of companies likely to require higher employee contributions, and n is the sample size. Substituting the given values into the formula, we have:

Margin of error = 1.96 * sqrt((0.62 * (1-0.62)) / 800)

Calculating this value gives us a margin of error of approximately 0.0245.

To compute the 95% confidence interval for the proportion of companies likely to require higher employee contributions, we can use the formula:

Confidence interval = p ± margin of error

Substituting the given values into the formula, we have:

Confidence interval = 0.62 ± 0.0245

Calculating this value gives us a confidence interval of (0.5955, 0.6445).

Jimmy wants to draw a 50° angle. Fill in the missing step to make sure his drawing is completed in the correct order:Step 1: He draws a ray.
Step 2: He lines up his protractor with the baseline on the ray and the origin of the protractor on the vertex.
Step 3: ________
Step 4: He uses the bottom of the protractor to draw a straight line connecting the mark he made with the vertex.
Step 5: He draws arrows on both ends to make them rays.

Anwsers:
1. He lines up his ruler with the ray and the zero on the ruler.

2. He finds 50° on the protractor and draws a mark on the paper.

3. He lines up his protractor with a straight line and draws a mark on the paper.

4. He draws parallel lines.

Answers

Answer:

2. He finds 50° on the protractor and draws a mark on the paper.

Step-by-step explanation:

Construction is a topic that requires a step wise procedure during the process. In the given question, since Jimmy wish to draw an angle of 50°, he should locate the angle on his protractor and draw a mark on the paper. This is with respect to the previous steps observed.

The essence of the protractor is for Jimmy to accurately measure the angle. Thus he has to determine the angle by the use of a protractor before the construction can be complete.

Therefore the required procedure in step 3 is he finds 50° on the protractor and draws a mark on the paper.

Answer He finds 50° on the protractor and draws a mark on the paper.

13. points help meeeeee

Answers

Answer: A

Step-by-step explanation:

For this problem, we can automatically eliminate B and D. We know this because of the inequality. The inequality is less than or equal to. anything that has an equal to sign is a solid line because any point on the line itself is a solution. If it was a < sign, it shows that the solution is less than, and not equal to. Therefore, the line would be dotted/dashed.

Now that we have figured out what type of line we have, we can see where the shading is located. To do so, we must make all the same variables go on the same side to see the equation.

y ≤ x²-4x+2

From this, we see that y is less than or equal to. This tells us that the shading is under the line. Under the line, y goes towards negative infinity, which makes y less than the line. Above the line, y goes towards positive infinity, which makes y greater than the line. That would make the inequality y≥x²-4x+2. Therefore, A is the correct answer.

It’s either A or B because it has the greater than OR equal to symbol

Draw a bar diagram for the equation and then solve 2,400/6=m

Answers

The solution to the equation is m = 400

What are equations

  • Equations are used to expressed quantities that are of equal values.
  • Equations are identified by the "=" sign

The equation is given as:

(2400)/(6) = m

Rewrite the above equation as

m =(2400)/(6)

Divide 2400 by 6

m =400

Hence, the solution to the equation is m = 400

I assume that no two people shake hands if they've already shaken them earlier, irrespective of who initiated it.

In that case Guest 1 will shake hands with 5 others (Guest 2 to 6)

Guest 2 will shake hands with 4 others (Remember she's already shaken hands with Guest 1).

Guest 3 will shake hands with 3 others (having already shaken hands with Guest 1 and 2)

and so on.....

We end up with 5+4+3+2+1 handshakes or 15 handshakes in all!
