Well compared to the parent function x^2, the graph of y=-3x^2+3 is flipped upside down (negative sign), steeper, and is up 3 units from the origin.
Natural number - 5
Irrational number - π
W-1/4= 3/7
W-1/4+1/4= 3/7+1/4
find the common denominator for the fractions
common denominator is 28
Multiply by 4 , top and bottom for 3/7
Multiply by 7 , top and bottom for 1/4
W= 12/28+7/28
W= 19/28
Answer is W= 19/28
Answer:
<em><u>Junae</u></em>
Step-by-step explanation:
<em><u>So, I am going to guess it is Junae because I wrote it in slope intercept form:</u></em>
y = -3/2x + 5/2
<em><u>Which means it wasn't already in that form? I hope I am right!</u></em>
First arrange the data in an order
3, 3, 3, 7, 7, 10, 10, 12, 12, 13, 14, 17, 17, 18, 21
a.) Q1 = (N + 1)/4th item = (15 + 1)/4 = 4th item = 7
Q2 = 2(16)/4 = 16/2 = 8th item = 12
Q3 = 3(16)/4 = 3(4) = 12th item = 17
IQR = (Q3 - Q1)/2 = (17 - 7)/2 = 10/2 = 5
b.) 82nd percentile = 82(16)/100 = 13th item = 17
c.) 12 is the 8th item which is in the middle of the data set, so the percentile rank is 50%
