The mean of eight numbers is 41.  The mean of two of the numbers is 29. What is the mean of the other six numbers​
GarryVolchara [31]

Answer:

45

Step-by-step explanation:

The mean is calculated as

mean = \frac{sum}{count}

Given the mean of 8 numbers is 41 , then

\frac{sum}{8} = 41 ( multiply both sides by 8 )

sum of 8 numbers = 328

Given the mean of 2 numbers is 29 , then

\frac{sum}{2} = 29 ( multiply both sides by 2 )

sum of 2 numbers = 58

The sum of the remaining 6 numbers = 328 - 58 = 270 , so

mean = \frac{270}{6} = 45

The mean of the other 6 numbers = 45

Isaac drove at an average speed of 49 mph over 6 hours during the first three hours he drove at a speed that was 172 mph less th
IgorC [24]

Isaac drove the car at 44 mph during last three hours.

Step-by-step explanation:

Average speed = 49 miles per hour

Let,

s be the speed during last three hours

4s-172 be the speed during first three hours

Average = \frac{Sum\ of\ items}{No.\ of\ items}

49=\frac{4s-172+s}{2}\\\\49*2=5s-172\\\\98=5s-172\\\\98+172=5s\\\\270=5s\\\\5s=270

Dividing both sides by 5

\frac{5s}{5}=\frac{270}{5}\\\\s=54

Speed during last three hours = 54 mph

Speed during first three hours = 4(54)-172 = 44 mph

Isaac drove the car at 44 mph during last three hours.
