Answer:
4.4
Step-by-step explanation:
Data set = 79, 93, 92, 86, 90
Xmean = (79 + 93 + 92 + 86 + 90)/5
= 440/5
Xmean = 88
MAD =
(79 - 88) + (93 - 88) + ( 92 - 88) + ( 86 - 88) + ( 90 - 88)/ 5
=
(9) + (5) + (4) + (2) + (2)/ 5
=
22/5
Mean Absolute Deviation = 4.4
To answer this you will need to find out how many quarts there are in 5 gallons. You can use the conversion of 4 quarts in 1 gallon to find out how many quarts there are in 5 gallons.
4 qts/1 gal = 20 qts/5 gal
Here will need to fill the container 20 times to fill the aquarium.
Answer:
10. 0
11. -16
12. 2
13. 2
14. 3
15. 0
Step-by-step explanation:
10. (x+4)(x-4) --> x= 4, -4 --> 4 + (-4) = 0
11. 4(-4) = -16
12. 2(x-2)² --> x = 2
13. 2
14. x(x-3) --> x= 0, 3, 0+3=3
15. 0(3) = 0
