<h3>
Answer: Approximately 2.1667</h3>
==========================================================
Explanation:
First we need to find the arithmetic mean.
Add up the values to get 3+8+6+9+2+5 = 33
Divide this over 6 because there are 6 values: 33/6 = 5.5
The mean is 5.5
------
Subtract the mean from each data value. Apply absolute value to ensure the result is not negative.
- |3 - 5.5| = |-2.5| = 2.5
- |8 - 5.5| = |2.5| = 2.5
- |6 - 5.5| = |0.5| = 0.5
- |9 - 5.5| = |3.5| = 3.5
- |2 - 5.5| = |-3.5| = 3.5
- |5 - 5.5| = |-0.5| = 0.5
Each result represents how far that specific data value is from the mean. Absolute value is used to find distance on a number line.
Add up each of those results to get: 2.5+2.5+0.5+3.5+3.5+0.5 = 13
Then divide by 6 to find the average: 13/6 = 2.1667 which is approximate
The mean absolute deviation represents the average distance any given value is from the mean. The term "deviation" refers to how far each data value is from the mean, which is the center point we're after more or less.
The MAD (mean absolute deviation) effectively measures how spread out the data set is. The larger the MAD, the more spread out the data is likely to be. The range, standard deviation and variance are also measures of spread.
(-2-2)^2+(-2-3)^2=16+25=41
Length is square root of 41
Answer:
152.99 m
Step-by-step explanation:
Using the solution diagram attached below :
We can obtain the height, h of skyscraper to the position of her eye level using trigonometry ;
Tan θ = opposite / Adjacent
Tan 24 = h / 340
h = tan 24 * 340
h = 151.37775
Hence, the height will be (h + distance from eyelevel to ground)
151.37775 + 1.61
= 152.98775
= 152.99 m
Answer:
$80.73
Step-by-step explanation:
115 * 0.35 = $40.25 off
115 - 40.25 = $74.75 after sale
add tax (0.08)
74.75 * 0.08 = $5.98 tax
74.75 + 5.98 = $80.73 in total
