Answer:
10
Step-by-step explanation:
IT WANTS YOU TO ESTIMATE IT SO YOU ROUND 48 TO 50 AND 35 TO 40 THEN YOU SUBTRACT 50 BY 40 AND THEN YOU GET 10.
Since mean is 100 so Λ=1/100,
But since exponential distribution is continuous distribution so probability at a particular points
Is zero. That probability
That X is equal to 90 degree is 0.
Answer: 3 different ways
Those three ways, I'll label as A, B, and C
A) Buying the 78 cookies one at a time
B) Buying 6 packs of the 13-count cookies, so 13*6 = 78 cookies total.
C) Buying 2 packs of the 39-count cookies, so 2*39 = 78 cookies total
--------
For option A, we can imagine a rectangle that is 1 unit high and 78 units long giving an area of 1*78 = 78. Or we can imagine a single row of 78 cookies in this row.
In option B, we can have a rectangle that is 13 by 6, giving an area of 78. Or We could have 6 rows of 13 cookies per row (each row representing a package of cookies).
Option C would be similar to B, instead there would be 2 rows of 39 cookies per row.
