To find the first quartile, we have to find the median of the lower data set.
Our real median is 17.5 approximately.
So taking the two points on the line before the 17.5 dot.
we have to add them together and divide by 2.
10 + 15 = 25
25/2 = 12.5
Therefore, our first quartile or q1 is 12.5
Answer:
No
Yes
Step-by-step explanation:
Let's find the inclination of the 3 lines.
m:
((-4) -3)/(0 - (-4))
-7/4
n:
((-2) -2)/(3 - 1)
-4/2
-2
k:
(1 -(-3)/(4 -(-3)
(1 +3)/4 +3
4/7
Okay, we find the inclination of all the three lines. For two lines be parallel, they have to have the same inclination. The inclination of m = -7/4 and the inclination of n = -2, so they're not parallel. And now, to know if m is perpendicular to k, they inclination have to be the opposite of the inverse of each other, so it means that they have to have opposite signals, and they need to be inverted fractions (for example a/b are inverted to b/a), and they are these two things: m = -7/4 and n = 4/7, so they're perpendicular

Answer:
-2 < -1.7 < -1.44.
Step-by-step explanation:
Convert them all to decimals:
-17/10 = - 1.7
- 2
-(1.2)^2 = - 1.44
so its -2 < -1.7 < -1.44.
I think it’s a yardstick.
Hopefully this helps...
