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.)

Step-by-step explanation:
A two-digit number, such as 79, contains a tens place and a ones place.
That is because 79 is also equal to 70 + 9.
The tens place is thus the 7, since since 7 × 10 = 70
and the ones place is the 9.
So lets Subtract breaking apart 143 - 79.
Break 79 down into its parts:
70 + 9.
Subtract 70 from the original number:
143 - 70 = 73
Subtract 9 from the answer:
73 - 9 = 64
Therefore, 64 is the final answer.

Answer:
x = - 6
Step-by-step explanation:
Let x b number, according to instructions´ we must
1.-Multiply by 4
2.-Subtract 6
3.-Divide by 2
4.-Arturo says his new number - 15
4,.Which one was the original number ??
The maths expression for that is :
(4*x - 6 ) / 2 = - 15
we solve for x
4x - 6 = - 30
4x = - 24
x = - 6
Final answer:
To find Arturo's starting number, reverse the given steps: divide by 2, add 6, then multiply by 4.
Explanation:
To find Arturo's starting number, we need to reverse the steps Savanna provided. Let's go through the steps backwards:
- Arturo's number after dividing by 2 is -15 * 2 = -30.
- Arturo's number after adding 6 is -30 + 6 = -24.
- Arturo's number after multiplying by 4 is -24 / 4 = -6.
Therefore, Arturo started with the number -6.

- y₁ = y₂ for x = 6
Step-by-step explanation:
In each case, put the x-value in the formula and do the arithmetic. If you're allowed, you can save some time and effort by realizing that the solution (x) will have to be an even number.
y₁ is an integer value for all integer values of x. y₂ is an integer value for even values of x only. y₁ and y₂ will both be integers (and possibly equal) only when x is even.
For example, for x = 6, we have
... y₁ = 3·6 - 8 = 18 -8 = 10
... y₂ = 0.5·6 +7 = 3 +7 = 10
That is, for x = 6, both columns of the table have the same number (10). That is, y₁ = y₂ for x = 6. The solution to the equation
... y₁ = y₂
is
... x = 6.

Answer:
y=2x+5
Step-by-step explanation:
distribute 2 to x and 1, do this by multiplying each.
you should get y-3=2x+2.
then you have to move the -3 from the left to the right. but when you do this you have to change the -3 to a positive 3. then combine 3 and 2.
you then get the answer, y=2x+5.
