Y=3x+2 is in slope intercept form. If you have a graph to go with this problem, if this equation is correct there should be points on (0,2) and (1,3)
When the number of data points is odd the formula to find the Ranking of the Median is (n+1)/2, When the number of data points is even the ranking of the Median will be the AVERAGE of n/2 + n/2 +1, where n is the number of data points.
In our case the ranking of the Median is the average (20+21)/2 = 20.5.
1- How many points are below the Median =20
Lower half = 20, Upper half = 20 & Median = 20.5 (Don't forget Median is the ranking of data points).
Again the 1st Quartile is at 10.5, so 10 data points are below the 1st Quartile
and 20 points are between Q1 & Q3
Step-by-step explanation:
1/4 √243 + √27/4 =
(¼ √81×3) + (¼ √9×3) =
9/4 √3 + 3/4 √3 =
12/4 √3 =3√3

The area of the circle depends on the square of pi.
Step-by-step explanation:
Answer:equal
Step-by-step explanation:
The probability that a random variable is greater than or equal to z standard deviations from the mean in a standard normal distribution he P(z≤a)+P(z>a)=1, so P(z>a)=1-P(z≤a)=1-.7116=.2884
