Answer: Q1 = 7.5
Q3 = 14
Step-by-step explanation:
Q1 means the lower quartile of a group of numbers and Q3 means the upper quartile. Once the median of such group of numbers are established then the the median of the lower set of numbers is the Q1 and the median of the upper set of numbers is the Q3.
We're given the data:
6,7,8,9, 11, 13, 14, 14, 18
Median of the general set of numbers = 11.
Q1= median of 6,7,8,9 = (7+8)/2 = 7.5
Q3 = median of 13,14,14,18 = (14+14)/2 = 14
Answer:
It takes them approximately 27 minutes to mow the lawn if they are working together.
Step-by-step explanation:
Wilma can mow a lawn in 80 minutes. This means she can mow at the rate of 1 lawn in 80 minutes. We can write this rate as R = 1/80
Melissa can mow the same lawn in 40 minutes. This means she can mow at the rate of 1 lawn in 40 minutes. We write the rate as R = 1/40.
Now, if the are working together, we need to determine how long it would take for them to mow a lawn. Let this rate be 1/x.
What we want to find is
1/80 + 1/40 = 1/x
Multiply through by 80, we have
1 + 2 = 80/x
3 = 80/x
Take reciprocals of both sides
x/80 = 1/3
x = 80/3
= 1600 seconds
Approximately 27 minutes
Answer:x) = 2x + 1
Step-by-step (x) = 2^x + 1 where x is an exponent of the number 2 Now to solve for the average rate of change of the given function from points x = 0 and x = 2, we must first assume that …explanation:
Add “24” six times and add a negative symbol in front of the answer. It’s pretty simple.
