Answer:
First one is quinton
second one is 900
Step-by-step explanation:
Brand A is. Just divide 100 (100% of a pickle) by each number, so 100 divided by 240 and 100 by 325. Then you multiply them by the fraction of 100, which 1/3 is 33.3% and 1/2 is 50%. It comes very close but A is the lowest.
Answer:
5.5
i just put the numbers in order and found the number(s) in the middle, which is 5 and 9 in this case. then i added them to get 11 and divided 11 by 2, which is 5.5
Answer:
0.9256
Step-by-step explanation:
Given that a convenience store owner claims that 55% of the people buying from her store, on a certain day of the week, buy coffee during their visit
Let X be the number of customers who buy from her store, on a certain day of the week, buy coffee during their visit
X is Binomial (35, 0.55)
since each customer is independent of the other and there are two outcomes.
By approximation to normal we find that both np and nq are >5.
So X can be approximated to normal with mean = np = 19.25
and std dev =
Required probability = prob that fewer than 24 customers in the sample buy coffee during their visit on that certain day of the week
= (after effecting continuity correction)
= 0.9256
Answer:
1st option
Step-by-step explanation:
We are summing the expression for n = 1 to n = 4 , that is
+ + +
1 ! = 1, 2! = 2 × 1 = 2 , 3! = 3 × 2 × 1 = 6 , 4! = 4 × 3 × 2 × 1 = 24 , then
+ + +
= 1 + 1 + +
