Step-by-step explanation:
The fraction is 4/10 * 2/9 = 4/45.
E = some event
C = complement of event E
Since the events are complementary, this means P(E)+P(C) = 1
We know that P(E) = 3*P(C) since "an event is three times as likely as its complement"
So we can replace P(E) with 3*P(C) and then isolate P(C)
P(E) + P(C) = 1
3*P(C) + P(C) = 1
4*P(C) = 1
P(C) = 1/4
The probability of the complementary event is 1/4
So the probability of the original event is 3/4 (three times 1/4)
Answer: 3/4
note: in decimal form, 3/4 = 0.75
Add up the sides and you will get your perimeter
When the max number is N the sum is = N*(N+1)
the answer is 35*36
Answer:
Step-by-step explanation:
Two variables, x and y, appear to be exponentially related. The regression equation for ln y on x is 
we need to predict the value of y when x=0.72
plug in the value of x in the given equation
