Answer:
Step-by-step explanation:
Let 
be the number of gallons so 
is the number of miles traveled per gallons.
We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by , his car will travel a total distance of 25g (where g is the number of gallons.
We also know that the total distance is given by , so we can put the two expressions together to get our function:
Let's check:
- If he uses 1 gallon (g=1), so
miles
He will travel 25 miles with one gallon.
- If he uses 2 gallons (g=2), so
He will travel 50 miles with two gallon.
Answer:
a)
Mean = sum of all numbers in dataset / total number in dataset
Mean = 8130/15 = 542
Median:
The median is also the number that is halfway into the set.
For median, we need to sort the data and then find the middle number which in our case is 546. Below is the sorted data
486 516 523 523 529 534 538 546 548 551 552 558 566 574 586
Standard Deviation (SD). Here X represents dataset and N= count of numbers in data
As per the SD formula, which is Sqrt ( sum (X_i - Meanx(X))/(N-1))
SD= 25.082
2) Formula for coefficient of skewness using Pearson's method (using median) is,
SK = 3* ( Mean (X) - Median(X))/(Standard Deviation) = 3*(542-546)/25.082 = -0.325
3) coefficient of skewness using the software method is also same which is -0.325
Answer: 83.8 +7
Step-by-step explanation:
im not sure what to go off of
3 more fewer days because 6+4=10 and 10-7=3.
Hope that helped:)
There are 6 seeds in carrot and 9 beets because 30 divide by 5 equals 6 and 45 divide by 5 equals 9.
