Answer:
It = 1
Step-by-step explanation:
25-24.75=0.25
0.25 / 25= 0.01
0.01 * 100 = 1
There are 24 possible answers, 6 are correct answers and 18 are incorrect answers. By use of the hypergeometric distribution the probabilities of each possible number of randomly selected correct answers can be found, as follows:
P(0) = 0.1379, P(1) = 0.3819, P(2) = 0.341, P(3) = 0.1213, P(4) = 0.017, P(5) = 0.0008, P(6) = 0.000007.
The expected or mean number of correct answers is found from:
The answer is: 1.4998
Answer:
3000 bags
Step-by-step explanation:
In this case we must apply the formula of the mean, which would be the sum of the values divided by the amount of data is the mean:
m = (a1 + a2 ... an) / n
In this case we know the mean, we must know the 1987 data, therefore:
Let x be the number of bags sold in 1987, replacing in the previous equation:
2100 = (1800 + 1500 + x) / 3
2100 * 3 = 3300 + x
x = 6300 - 3300
x = 3000
Therefore, for the average to be a total of 2100 bags in those 3 years, the amount of bag sold in 1987 must have been 3000 bags
I think six packs because it only takes 5 bags of the six pack to get 26 but it takes 7 packs of the four packs to only get 23 and 8 packs of the four pack to get 27 it’s a better deal to get the 5 packs of the $5.28 pack
Answer:
5^14
Step-by-step explanation:
We use the laws of indices:
When there is a power outside the bracket multiply the powers.
(a^m)^n=a^m×n
So (5^7)^2=
5^7×2
5^14
