Answer:
10
Step-by-step explanation:
By using intersecting chord theorem:
NH.HT=MH.HY
(x+20)*8=12*20
x+20=12*20/8
x+20=240/8
x+20=30
x=30-20
x=10
Answer:
0.8
Step-by-step explanation:
We can solve P(A or B) by using the following:

Since we know P(A) = 0.6, P(B) = 0.3 and P(A and B) = 0.1 we obtain:

Answer: No
Step-by-step explanation: Because it is.
Answer:
Step-by-step explanation:
PART 1
y=mx+b
m is slope and slope is 0 sooo
y=0x+b
it passes through (3,7)
7=0(3)+b
7=0+b
b=7
y=0x+7
so just y=7
PART 2
y=mx+b
y=1/5x+b
1/2=1/5(-2/3)+b
1/2=-2/15+b
1/2+2/15=b
15/30+4/30=b
19/30=b
y=1/5x+19/30
Answer:
Step-by-step explanation:
4 + 2x < 6 + 6x
4 - 4x < 6
-4x < 2
x > -1/2
