Hi there,
A rectangle has got 2 lengths, and 2 widths, so we have got the formula:
P = 2·L + 2·l, where P - perimeter, L - length, and l - width.
P -- 2·L = 2·l, if we divide everything by 2, we have
P/2 -- L = l, so l = P/2 -- L = 76/2 -- 20 = 38 -- 20 = 18 cm, so l = 18 cm.
Was it difficult ?

14 < n - 3
We must isolate n. To do that we must bring -3 to the left side of the equation. To make -3 zero on the right side of the equation and bring it to the left side you must add 3 to both sides like so...
14 + 3 < n + (-3 + 3)
17 < n + 0
17 < n
Hope this helped!

Answer:
We want to find the following probability:
And using the probability mass function we got
Step-by-step explanation:
Let X the random variable of interest "number of orders on time", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:
And using the probability mass function we got
