Answer:
blue and i dont know he answer
Answer:
a)
P(X = 0) = 5/10
P(X = 5) = 3/10
P(X = 10) = 2/10
b)
E = 0·5/10 + 5·3/10 + 10·2/10 = 3.5
V = 0^2·5/10 + 5^2·3/10 + 10^2·2/10 - 3.5^2 = 15.25
Stop 1 : -
15 + 5 = 20
20 - 2 = 18
So, on the first stop 18 passengers were left on the bus going to the next stop.
Stop 2 : -
18 + 3 = 21
21 - 15 = 6
So, 6 passengers get off at the 2nd stop.
Hope I helped ya!!
You're basically multiplying the number and the variable with the number on the outside of the parenthesis.
So, 8(x + 7). You multiply 8 and the variable to get 8x. The same with '7'.
8 times 7 is 56.
Answers:
A) 8x + 56
B) 66 + 6x
C) 8x + 8
ANSWER:
m∠1 = 60°
m∠2 = 60°
m∠3= 120°
EXPLANATION:
The purple arrows indicate that side are parallel, so we know that that triangle NMP is the same as triangle NOP. If they are they same then we know that ∠1 and ∠2 equal 60° since the opposing angles equal 60°.
For ∠3 we look at the opposing angle and now know it is 60°. Since ∠3 and the opposing angle make a straight line which equals 180°. We can figure out ∠3 by subtracting 60 from 180 = 120°.
