81.4% ≅ 81%. The probability that a customer ordered a hot drink given that he or she ordered a large is 81%.
The key to solve this problem is using the conditional probablity equation P(A|B) = P(A∩B)/P(B). Conditional probability is the probability of one event occurring with some relationship to one or more other events.
Similarly to the previous exercise, P(A∩B) is the probability that a customer order a large hot drink. So, P(A∩B) = 22/100 = 0.22
For P(B), is the probability that a customer order a large drink whether hot or cold. P(B) = 27/100 = 0.27
P(A|B) = 0.22/0.27 = 0.814
multiplying by 100%, we obtain 81.4%

Answer:
21/4
Step-by-step explanation:
21 y = -4x Divide 21 on both sides
y = -4/21x Slope is -4/21
Perpendictulare lines have a slope that are the negative inverses of eachother, so flip the 4 and the 21 and make it positve instead of negative
The polynomial 
arranged in descending order is 
Step-by-step explanation:
We need to rewrite the polynomial in descending order.
For writing the polynomial in descending order we arrange the exponents of variables from largest exponent to the smallest exponent.
The given polynomial is:
The descending order of the polynomial is:
So, the polynomial arranged in descending order is
