Answer:
w(-15-w)= 0
w= 0 or (-15-w) = 0
Now,
-15-w =0
w= -15
So,The solution of w(-15-w) = 0
w= 0, -15
Answer:
Q (2.5, -4)
Step-by-step explanation:
Let A (1, -5), C = (10, 1), find Q (x, y), so that AQ:QC = 1:5
AQ = (x - 1, y + 5)
QC = (10 - x, 1 - y)
AQ:QC = 1:5
so 5*AQ = QC
5(x - 1) = (10 - x)
5(y + 5) = 1 - y
Solve them:
5x - 5 = 10 - x
6x = 15
x = 15/6 = 2.5
5y + 25 = 1 - y
6y = -24
y = -24/6 = -4
Then answer is Q (2.5, -4)
Answer:
<u><em>8/20</em></u>
Step-by-step explanation
<em>boys left handed=3
</em>
<em>boys right handed=9
</em>
<em>girls left handed=2
</em>
<em>girls right handed=6
</em>
<em>what is the probability that a student chosen from random is a girl? give answer as a fraction please and include step by step process</em>
<em>girls left handed: 2</em>
girls right handed: 6
6+2=8
total all students 20
<em>8/20</em>
