To find the IQR you first need to write it in numerical order
77, 81, 83, 84, 86, 86, 88, 92
IQR is just Q3 - Q1
Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82
Q3 done the same process would be 87.
87 - 82 = 5
IQR = 5
(0,4)(4,0)
slope = (0 - 4) / (4 - 0) = -4/4 = -1
y = mx + b
slope(m) = -1
use either of ur points....(0,4)...x = 0 and y = 4
sub and find b, the y int
4 = -1(0) + b
4 = b
equation is : y = -x + 4....in standard form, it is : x + y = 4
Answer: 684
Step-by-step explanation:
95% of 720
Move decimal point two places to the right.
0.95 * 720 = 684
each of the sides of your equation
by the value of
on each of your sides
(you get this because we solve the particular equation we added above)
on each of your sides
because it equals to
because it brings us closer and closer to the answer of
by the number
on each of your sides
