Options:
- 30; it represents the hourly wage for the worker
- 30; it represents the cost for insurance
- 10; it represents the hourly wage for the worker
- 10; it represents the cost for insurance
The answer is the third option "10; it represents the hourly wage for the worker." 10 would be the slope and if x represents hours then 10 would represent the amount of money the worker would get every hour.
Hope this helps!
Answer:
I don’t understand
Step-by-step explanation:
4,034.06 ,5,965.94 are confidence interval for the population average wages at the factory.
What is confidence interval estimation?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. Another term for probability in statistics is confidence.
The formula for confidence interval estimation is:
μ = M ± Z(sM)
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
M = 50000
Z = 2.58
sM = √(30002/64) = 375
μ = M ± Z(sM)
μ = 50000 ± 2.58*375
μ = 50000 ± 965.94
μ = 4,034.06 ,5,965.94

<u>First, find the perpendicular slope</u>
y = 0.3x + 6 ⇒ m = 0.3 =
perpendicular slope =
<u>Next, input</u> the point (x₁, y₁) and slope (m) into the Point-Slope formula
y - y₁ = m(x - x₁)
y - (-8) = (x - 3)
y + 8 = + 10
y = + 2
The correct answer would be D.
The mechanic would charge x amount per hour,
so it would look like:
x(time)
So lets say every hour was $5 and he worked on it for 5 hours, then it would be
$5(5)
