Jonathan, a researcher, wants to know the average variation in altimeters of small, privately owned airplanes. This task is expe

nsive and time-consuming, if even possible, given the large number of such airplanes. Jonathan decides to use government records to randomly locate the owners of 10 such planes, and then solicit permission to test the altimeters. When Jonathan is done, he will use the data gathered from the group of 10 to reach conclusions about all small, privately owned airplanes. The average variation computed using the data gathered on the group of 10 airplanes is best described as

Answer: Inferential statistics

Explanation:

Inferential statistics is defined as the method in which a data sample is taken from population so that inference about basic population can be made. Conclusion about certain characteristic or property of bigger population from small sample is based upon considering sample as guideline for wider group of population.

According to the question,Jonathan is using inferential statistic method for researching about average differences in small airplanes which are owned privately by people. Instead of conducting research on large amount of such planes, he is performing it on ten planes sample with the help of government record.

This group of ten planes are representing major population of small and private planes.Thus, the output remarking about variation in group of ten planes will represent the basic variation present in population of such planes.

Hi there!

Since the triangle is equilateral, all of its sides are congruent. This means that to solve, we can set the two given equations equal to each other.

2(x - 8) = 1/2x + 8
2x - 16 = 1/2x + 8
1.5x - 16 = 8
1.5x = 24
x = 16

Now that we know what x is, we can plug that in for x in the equation for ZY.

2(16 - 8) = ZY
ZY = 2(8)
ZY = 16 units

And here is the work to show that XZ is also 16.

1/2(16) + 8 = XZ
XZ = 8 + 8
XZ = 16

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

The following annual expenses for car insurance, vacation, and home repairs for the Clark family are $1130, $700, and $468, resp
eimsori [14]

Answer:

A) $192

Step-by-step explanation:

Given:

Yearly expense of Car insurance = $1130

Yearly expense of Vacation = $700

Yearly expense of home repairs = $468

we need to find the monthly allowance of Clark family.

First we find the total annual expense of Clark family.

Total Annual expense is equal to sum of Yearly expense of Car insurance and  Yearly expense of Vacation and Yearly expense of home repairs.

Framing in equation form we get;

Total annual expense = \$1130 + \$700+\$468 = \$2298

Now we know that;

Number of months in a year = 12 months.

Total Monthly allowance will be equal to Total annual expense divided by Number of months in year.

Framing the equation we get;

Total Monthly allowance  = \frac{\$2298}{12}= \$191.5

Rounding to nearest dollar we get;

Total Monthly allowance of Clark family is $192.
