Answer:
Quartile 1 is 18
Step-by-step explanation:
Arrange the numbers in order from least to greatest;
18, 18, 18, 20, 21, 22, 23, 23, 24, 24
Find the Median = (21+22)/2= 21.5
Find the median (Q1) between 21.5 and 18 = 18
Find the median (Q2) between 21.5 and 24 = 23
In order to find the answer, we'll divide 49.5 by 56.25. Once you do that, you'll get your answer.
Answer:
A.
Step-by-step explanation:
The figure moves to the right 8 units which is positive and then up 7 units which is also positive.
-3x - 4y - 2z = 0
x + 3y + 2z = 1
-2x - y = 1
-4x - 4y - 2z = 10
3x + 4y +2z= 0
-x = 10. x = -10
-2(-10) - y = 1
20 - y = 1
-y = -19
y = 19
-10 + 3(19) + 2z = 1
-10 + 57 + 2z = 1
47 + 2z = 1
2z = -46
z= -23
check: 2(-10)+2(19)-23=-5
-20+38-23=-5
-43+38=-5
-5=-5
