Answer:
15.6
Step-by-step explanation:
First, multiply the midpoint of each class by its frequency, as follows:
Class midpoint frequency midpoint*frequency
0-9 4.5 24 4.5*24 = 108
10-19 14.5 20 14.5*20 = 290
20-29 24.5 32 24.5*32 = 784
Total 76 1182
The mean is computed as the division between the addition of the "midpoint*frequency" column by the addition of "frequency" column.
mean = 1182/76 ≈ 15.6
Answer:
16 3/10
Step-by-step explanation:
Think about what fraction become .3 when put into a calculator
that's a 3 in the tenths place in the decimal system so the fraction would be 3/10. Then finally add on the 16
*an aside if this is wrong it it is possible that they have rounded 1/3 to one decimal place. (1/3 is usually .33333 repeating)
6x+12y-6z+7x7y-28z= 13x+19y-34z
Step-by-step explanation:
So you should use headphones while doing writing work and if digital work then take very short brakes during study and concentrate fully.
