Answer:
The answer is
A) Skewed left
Step-by-step explanation:
The line plot has about 3 point that are going more to the left than the others therefore it is skewed left.
x=18 y=69
3x+5y=399
x+5y=363
2x=36
x=18
18+5y=363
5y=345
y=69
c. The tip is $10.00
The total bill in the restaurant is = $ 68.42
They wanted to pay a gratuity of 15%
Therefore the correct tip can be calculated as :
= 68.42 of 15%
=
= 68.42 x 0.15
= 10.263
≈ 10 (approx.)
Thus the individual along with the other two wishes to pay a tip $10.00 for the total value.
2x+3(10+x)
I'm not sure but I think this might be the answer
The sample standard deviation is 15.3.
Given data items,
84, 85, 83, 63, 61, 100, 98,
Number of data items, N = 7,
Let x represents the data item,
Mean of the data points,
Hence, sample standard deviation would be,
