Answer:
Step-by-step explanation:
Let X be the no of customers who purchase atleast one item.
X is binomial since there are two outcomes and each customer is independent of the other.
a) Here n =10
Out of 10 customers we expect np = 3 customers to buy at least one item.
b) exactly 3 of the customers would purchase at least one item
=
c) the probability that no more than 3 customers would purchase at least one item
=
Answer:
the formula to find slope is m=y1-y2/x1-x2
using this formula 8-6/8-(-4)
=2/8+4
=2/12 simplify
=1/6
Answer:
=12x+y
Step-by-step explanation:
Combine like terms
=5x+-3y+7x+4y
=(5x+7x)+(-3y+4y)
=12x+y
X1 = 12
X2 = 4
I took the test and can promise you this is correct!!
