Hello,
we are going to use the theorem of the bissectrice. (if this word is good in english)
Answer: 3.8168
Step-by-step explanation:
7.34 x 0.52
3.8168
M= y1-y2/x1-x2
m= 8/10
m= 4/5
Answer: Third option
Step-by-step explanation:
You have the function:
Then, if the value of x increases by 1, you obtain:
-Rewrite the function:
-Substitute values for x into the function and observe what happen to y. Then:
x=1
x=2
x=3
The value of y is doubled.
Answer:
(c)
Step-by-step explanation:
As given in the statement, we have:
Out of 4 games pieces, 1 is winner.
Probability to win =p=
Jeff has game pieces = n = sample size = 4
As we need to find the probability that he wins exactly 1 prize, we will use binomial probability here :
Evaluating at k=1, (k=1 as we need to find probability for exactly 1 prize won)
put n = 4, p =
P (X = 1) =
P =
Which is the probability that he wins exactly 1 prize and is option c.
