Answer:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|
Step-by-step explanation:
Answer:
its 15.43
Step-by-step explanation:
you didnt put a picture for the polygons but im pretty sure this is from math nation.
1)
8.75 * 20 = 175
8 * 20 = 160
175 - 160 = 15
He'd make $15 more working at the amusement park.
2)
Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.
3280 * 2 = 6560 (is what she makes per month)
6560/4 (because 4 weeks in a month) = 1640
OR (An alternative method.)
3280/2 = 1640
She'll be paid $1640 per week.
4)
105,000/12 (12 months in 1 year) = 8750 (He makes this per month)
8750 * 2 = 17500
He makes 17500 semi monthly
8750 /4 = 2187.5
2187.5 * 2 (because bi-weekly) = 4375
He makes 4375 bi-weekly
8750/4 = 2187.5
He makes 2187.5 every week
Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.
Use Pythagoras’ theorem:
a^2+b^2=c^2
But we rearrange this formula to make it
c^2-a^2=b^2
So 25^2-15^2=b^2
625-225= b^2 = 400
You now need to find the square root of 400 to find the square root of b
sqrt of 400 is 20
So 20 is the missing length in this triangle
D: −2 ≤ x ≤ 2
R: −3 ≤ y ≤ 3
