Answer:

x = 105

Step-by-step explanation:

the sum of all interior angles of any four-sided figure has 360 degrees

∡F and ∡H are equal

add all four expressions and set them equal to 360

x + (x + 5) +( x + 5) + (140 - x) = 360

combine like terms

2x + 150 = 360

2x = 210

x = 105

Use the data set to answer the question. {22,26,28,35,45,63,91} What is the mean absolute deviation (MAD) of the data set? Enter

shtirl [24]

Answer:

mean absolute deviation is 18.85

Step-by-step explanation:

<u>Step 1:</u>-

Given observation values 22,26,28,35,45,63,91

$mean (x ) = \frac{22+26+28+35+45+63+91}{7}$

mean = 44.28≅ 44

<u>Step2</u>:-

The deviations of the respective observations from the mean (x)

That is $x_{i}-x$

22-44, 26-44,28-44,35-44,45-44,63-44,91-44

-22, -18 ,-16 ,-9, 1, 19, 47

<u>Step 3:</u>-

The absolute values of the given data

$x_{i}-x$

modulus of all these values

22,18,16,9.1,19,47

<u>Step 4</u>:-

Mean absolute deviation M.D=∑ $\frac{x_{i} - x }{n}$

$MAD = \frac{22+18+16+9+1+19+47}{7}$

on simplification we get mean absolute deviation is 18.85

As a graduating senior, Chun Kumora of Manhattan, Kansas, is eager to enter the job market at an anticipated annual salary of $4

ludmilkaskok [199]

1. Chun Kumora's salary after 11 years will be <u>$63,117.6200</u>.

2. Chun Kumora's salary after 21 years will be <u>$93,429.4900</u>.

3. Chun must receive raise greater than <u>$42,640</u> ($41,000 x 1.04) for the next year and greater than <u>$44,345.6000</u> ($42,640 x 1.04) for the year after.

<h3>How are the future salaries determined?</h3>

The future salaries (values) can be determined using an online finance calculator that compounds with the sum of the average inflation rate of 2% and the cost-of-living raise of 2% for 11 and 21 years, respectively.

<h3>Data and Calculations:</h3>

Future Value in 11 years:

N (# of periods) = 11 years

I/Y (Interest per year) = 4% (2% x 2)

PV (Present Value) = $41,000

PMT (Periodic Payment) = $0

<u>Results</u>:

FV = $63,117.62 ($41,000 + $22,117.62)

Total Interest = $22,117.62

<h3>Future Value in 21 years:</h3>

N (# of periods) = 21 years

I/Y (Interest per year) = 4% (2% x 2)

PV (Present Value) = $41,000

PMT (Periodic Payment) = $0

<u>Results</u>:

FV = $93,429.49 ($41,000 + $52,429.49)

Total Interest = $52,429.49
