Maria will do more laps this year, assuming that last year they didn't do one or zero laps.
Answer: 
Step-by-step explanation:
Given
The central angle of a sector measures 
The radius of the circle is 
The area of the sector is given by
Insert the values
Elegant ejaculation first the kiss then the c0m
First <u>rewrite the equation</u> in slope intercept form
slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]
<u>comparing</u> with y = mx + b
- slope: -1/4 and y-intercept: 4
x-intercept: ( then y will be 0 )
In order to graph the line
- plot x = 16 on the x-axis coordinate: (16, 0)
- plot y = 4 on the y-axis coordinate: (0, 4)
- Then using a scale/ruler draw a straight line through this points.

Answer:
B.
Step-by-step explanation:
There are 20C4 = 4845 ways to take a sample of 4 from 20.
For choices A and C, the mean will be over-estimated if 3 of the 4 samples are of the higher value. There are (10C3)×10 = 1200 samples that will cause the mean to be over-estimated.
For choice D, every sample will correctly estimate the mean, so there are 0 samples that will cause the mean to be over-estimated.
For choice B, any sample that contains all 2s will over-estimate the mean. There are 19C4 = 3876 such samples.
Of the data sets listed, a sample of 4 from data set B is most likely to be one of the samples that will over-estimate the mean.
