(1) $168.74
On number 2, I didn't fully understand the percentage isn't getting an corrwct answer and i'm puzzled.
The complete question in the attached figure N 1
we know that
The formula for Sample Standard Deviation is indicated in the attached figure N2
n in this problem is 4 <span>and Yuri had to divide in the formula by 3 </span>
therefore
the answer is Yuri divided by n instead of n -1
Answer:
d = 1.75 miles
Step-by-step explanation:
A track team ran 8 and 3/4 miles in 5 days.
We need to find the distance covered by it each day. Let the distance is d.
miles in 5 days
or
miles in 5 days.
So, each day the team will cover 1.75 miles.
Answer:
I don't understand the question can you provide a picture of the question please?
Let's assume that Susan's graph is linear. Then, we can do linear interpolation. Let y be the amount charged for 10 hours of work done:
(7-10)/(7-11) = (168-y)/(168-264)
y = $240
For Jim's Lawn care, let's find the constant slope using points (1,20) and (2,40):
m = (20 - 40)/(1-2) = 20
Then, since the y-intercept is zero, the linear equation is:
y = 20x
Substituting x = 10 hours,
y = 20(10) = $200
The difference between the two would then be:
Difference = $240 - $200 = $40
