Answer:
The slope is -5
Step-by-step explanation:
<u>Slope is the number attached to the x</u>
For this problem, y = -2/3 - 5x, the slope/number attached to the x is -5. So, the slope is -5.
Answer: The slope is -5
Let units cancel out just like numbers...
25365.4cm^3(2.7g/cm^3)=68486.58g which is 68486.6g (to nearest tenth)
Answer:
45 minutes
Step-by-step explanation:
let after t hours they meet after the second runner starts.
15 minutes=1/4 hour.
6(t+1/4)=8t
6t+6/4=8t
8t-6t=6/4
2t=3/2
t=3/2* 1/2=3/4 hours=45 minutes
If we draw the contingency table of x (vertical) against y (horiz.), we have a square.
For n=4, we have (legend: < : x<y = : x=y > : x>y
y 1 2 3 4
x
1 = < < <
2 > = < <
3 > > = <
4 > > > =
We see that there are n(n-1)/2 cases of x<y out of n^2.
Therefore,
p(x<y)=n(n-1)/(2n^2)=(n-1)/(2n)
However, if the sample space is continuous, it will be simply p(x<y)=1/2.
