Answer: The graph of line
Step-by-step explanation:
Since, here x represent the number of slices of pizza purchased, and let y represent the total cost.
And, According to the question,
Will bought 4 slices of pizza for $6.00.
Therefore, the price of one slice pizza = 6/4 = $3/2
Thus, the price of x pizza = 3x/2
But, the price of x pizza = y
Therefore, y = 3x/2
Which is the required equation of line.
And, this line passes through the origin.
If x =2 y =3
If x= 4 y = 6
If x = 8 , y= 12
Thus, the points of the line are ( 2,3), (4,6) and (8,12)
Therefore, we can plot the graph of the line with help of above information.
Answer:
(a) more than 2 such accidents in the next month
(b) more than 4 such accidents in the next 2 months
(c) more than 5 such accidents in the next 3 more than 5 such accidents in the next 3 months
Step-by-step explanation:
Let N be the Random variable that marks the number of crashes in certain month.
Now let us use Poisson distribution since we are given with average number of crashes that is N \sim Pois(2.2)
(A) more than 2 such accidents in the next month
Probability(more than 2 such accidents in the next month)=P(N>2)
P(N>2)=1-P(N=0)-P(N=1)-P(N=2)
=>
=>
B) more than 4 such accidents in the next 2 months
since the average number of crashes in 1 month is 2.2, the average number of crashes in two months is 4.4. hence, if we say that is the number of crashes in 2 months, we have that
Pois(4.4)
Thus,
Probability(more than 4 such accidents in the next 2 months)=P()
=
=>
C) more than 5 such accidents in the next 3 more than 5 such accidents in the next 3 months
If we say that marks the number of crashes in the next 3 months , using the same argument as in (a) we have that a
Pois(6.6)
Hence
P()=
=>
