Answer: 22 minutes
Step-by-step explanation: 500-170 means that he drained 330 gallons of water so 330 divided by 15 gallons a minute so you get 22 so it takes 22 minutes to have 170 gallons left in the pool
Answer:
495 degrees
Step-by-step explanation:
2/3 divided by 4= 2/3x1/4 (flip 4 around). 2x1=2 & 3x4=12. 2/12 or 1/6
For this case we have the following complex number:
1 + i
Its equivalent pair is given by:
root (2) * (cos (pi / 4) + i * sin (pi / 4))
Rewriting we have:
root (2) * (root (2) / 2 + i * (root (2) / 2))
(2/2 + i * (2/2))
(1 + i)
Answer:
option A represents a pair with the same complex number
Answer:
Mean= 13.38
Median= 15
Step-by-step explanation:
The mean can be calculated by getting the sun of the 8 scores and then dividing it by the number of students
Mean= 7 + 18 + 18 + 15 + 17 + 10 + 15 + 7/8
= 107/8
= 13.38
The median can be calculated by first rearranging the numbers from the lowest to the highest and then calculating the average of the two middle numbers
7 , 7, 10, 15, 15, 17, 18, 18
Median = 15+15/2
= 30/2
= 15
Hence the mean is 13.38 and the median is 15
