Set up a ratio for this problem:
.25 in/50 miles = 2.5 in/x
.25x = 125
then divide by .25
The actual distance is: 500 miles
A. They are both proportional because they have the same ratio.
b. The two graphs are the same because they have a constant rate of change (50), but they have different y-intercepts.
Answer:
you would get your answer by timesing all the numbers together, that it gives you.
Step-by-step explanation:
If my math is correct it would be the second one.
Answer:
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
Step-by-step explanation:
let assume that stick has length 1.Random variable L that make length of a longer piece and random variable U that mark point .See that L < l means that
U≤ l and 1-U ≤l
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
this means 1-l≤U≤l
so we have
if we have L [1/2,1]
then apply the formula we have E(L)=3/4
Domain : ( – ∞ , ∞ ) , {x/x ∈ R }
Range : [ 0 , ∞ ) , { y/y ⩾ 0 }
I hope I helped you^_^
