Answer :
0.2322
Step-by-step explanation:
Proportion, p of those who used e - ticket to get boarding pass = 112 / 280 = 0.4
p = 0.4
1 - p = 1 - 0.4 = 0.6
Number of samples, n = 8
P(x = 4)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 4) = 8C4 * 0.4^4 * 0.6^4
P(x = 4) = 70 * 0.0256 * 0.1296
P(x = 4) = 0.2322432
P(x = 4) = 0.2322
Answer:
Combine -15 + 2n first, then you get -13 n.
Then work from -13n to subtracting -9n, that is -4n. Now all you have left is -4n = 8. Divide both sides by -4n/-4 8/-4. The answer is n = -2.
Step-by-step explanation:
Let
x = scale
For this case you should count how many divisions there are in the longest dimension.
14
Then, as the longest dimendion of the park is 63 meters then, the scale is
14x = 63
x = 63/14
x = 4.5
answer
the scale is 4.5m
