Answer:
let c = cashew pounds, w = walnut pounds, m = mixed pounds
Here's what we know:
c + w = m
7c + 5.5w = 6.50m
m = 35
So we now have:
c + w = 35
7c + 5.5w = 227.5
We can use substitution or elimination here. Let's try substitution in this case:
c = 35 - w
7(35 - 7) + 5.5w = 227.5
245 - 7w + 5.5w = 227.5
245 - 1.5w = 227.5
-1.5w = -17.5
w = 11 2/3
Now to solve for cashews:
c = 35 - 11 2/3
c = 23 1/3
Check:
23 1/3 * 7 + 5.5 * 11 2/3 = 227.5
163 1/3 + 64 1/6 = 227.5
163 2/6 + 64 1/6 = 227.5
227 3/6 = 227.5
227.5 = 227.5

Answer:
k = 4
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
. So
P(X < k) = 0.6625
k only assumes discrete values, so
We have to find the cummulative distribution until we hit 0.6625. So
So k = 4
