5j
Step-by-step explanation:
Alright! First you'd have to subtract the flat fee of the mug which is $8.95, then you'd have to divide by the rate which is $1.50. Your equation would be:
(26.95 - 8.95) ÷ 1.50 = r
Then you solve using your head.. lol.
(26.95 - 8.95) = 18.
(18 ÷ 1.50) = 12.
R = 12.
Hope this helps :).

Answer:
Step-by-step explanation:
Horizontally the table values total the number in the first column.
first row missing table value = 700 -665 = 35
second row missing table values = 300 -240 = 60
__
The conditional probability formula applies.
P(contains | positive) = P(contains & positive)/P(positive)
The probability associated with each table entry is that value divided by 1000. Then the numbers in the formula are ...
P(contains | positive) = .665/(.665+.060) = .665/.725 ≈ 91.7%
