Answer:
4.25
Step-by-step explanation:
Here in this question, we want to calculate the mean absolute deviation of the data.
The first thing we will do here is to calculate the mean;
= (74 + 79 + 76 + 85 + 87 + 83 + 86 + 78)/8 = 81
Now, the next thing to do here is to calculate how far each of the values have deviated from the mean. This can be calculated by subtracting the mean from each individual value;
This is presented in the table on the attachment, please check attachment for this
Afterwards, we find the absolute value of all these subtractions then divide by 8 which is the number of values in the data.
Mean absolute deviation = Sum of all absolute deviations/number of values in dataset
Answer:
D) e
Step-by-step explanation:
ln e^e
We know that ln x^a is the same as a ln x
e ln (e)
we know that ln e =1
e (1)
e
P=2
X=4
D=3
Y=4.5
You’re welcome
Answer:
Student-A:
mile/min
Student-B:
mile/min
Student-C:
mile/min
Step-by-step explanation:
Student-A:
she can run 2/3 mile in six minutes
so,
total distance is 
miles
total time =6 min
we can use formula
speed=(total distance)/(total time)
mile/min
Student-B:
she can run 1/2 mile in 4 minutes
so,
total distance is 
miles
total time =4 min
we can use formula
speed=(total distance)/(total time)
mile/min
Student-C:
she can run 4/5 mile in 8 minutes
so,
total distance is 
miles
total time =8 min
we can use formula
speed=(total distance)/(total time)
mile/min
The answer is 10.
(a - b)² = a² + 2ab + b²
(-x - 5)² = (-x)² - 2 * (-x) * 5 + 5²
= x² + 10x + 25
