Find the margin of error for the given values of c, o, and n.

Mathematics

Alika [10]2 years ago

Using the z-distribution, it is found that the margin of error is of 0.059.

We are given the standard deviation for the population, hence the <em>z-distribution</em> is used.

<h3>What is the margin of error for a z-confidence interval?</h3>

It is given by:

M = z\frac{\sigma}{\sqrt{n}}

In which:

  • z is the critical value.
  • \sigma is the population standard deviation.
  • n is the sample size.

In this problem, the parameters are:

  • \sigma = 0.25, n = 49.
  • Confidence level of 0.90, hence, using a z-distribution calculator, the critical value is z = 1.645.

Then:

M = z\frac{\sigma}{\sqrt{n}}

M = 1.645\frac{0.25}{\sqrt{49}}

M = 0.059

The margin of error is of 0.059.

How much does Greg earn per hour? Explain how to determine the unit rate from the table?
Butoxors [25]

Answer:

Well you can already answer that(37)

Step-by-step explanation:

In 3 hours and 30 minutes Greg has earned 64.75 dollars if you take that amount(the amount earned in 3 and a half hours) and divide it by the 3 1/2 hours(the time it took to earn that amount) you get 18.50 which is the amount you earn per half hour since that graph is increasing at 30min. per 18.50 or the amount.

Please help with the steps as well!!
mariarad [96]

To solve this problem, we need to use the Pythagorean Theorem, which states that a^2 + b^2 must equal c^2. "a" is the length of one of the legs (shorter sides of the triangle) and "b" is the length of the other leg. "c" is the length of the hypotenuse.

a = y = 36.25cm

b = x = 20.93cm

a^2 + b^2 = c^2

(36.25)^2 + (20.93)^2 = c^2

1314.0625 + 438.0649 = c^2

√1752.1274 = √c^2

c = 41.8584209 ≈ 41.86

So your final answer is...

The length of the hypotenuse is about 41.86 cm.
