Answer:
0.0765 = 7.65% probability that, for any day, the number of special orders sent out will be exactly 3
Step-by-step explanation:
We have the mean, which means that the poisson distribution is used to solve this question.
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
The auto parts department of an automotive dealership sends out a mean of 6.3 special orders daily.
This means that
What is the probability that, for any day, the number of special orders sent out will be exactly 3?
This is P(X = 3). So
0.0765 = 7.65% probability that, for any day, the number of special orders sent out will be exactly 3
Answer:
-3
Step-by-step explanation:
The slope for two points is found by
m = (y2-y1)/(x2-x1)
= (4--2)/(0-2)
= (4+2)/(0-2)
= (6/-2)
=-3
Answer:
The length is 9.
The width is 7.
Step-by-step explanation:
A rectangle has two dimensions.
The width, which is the distance between the points who have the same value of y.
The length, which is the distance between the points who have the same value of x.
Distance between 2 points:
Points (a,b) and (c,d).
Same value of x:
(-1,1), (-1-8) or (6,1), (6,-8)
The distance for both of them is the same, can calculate for only one.
The length is 9.
Same value of y:
(-1,1), (6,1) or (6,-8), (-1,-8)
The width is 7.
Answer:
$24
Step-by-step explanation:
James
Allowance per week = $6
He spends = $4
Balance = $6 - $4 = $2
Mike
Allowance per week = $7
He spends = $3
Balance = $7 - $3 = $4
Their mother's birthday is in 4 weeks
how much money can they save together in that time to buy her present?
James savings per week × 4 weeks
= $2 × 4
= $8
Mike's savings per week × 4 weeks
= $4 × 4
= $16
Total amount James and Mike can save together = $8 + $16
= $24
