Alright, so she drives 64.5*5 (for 5 days)=322.5 miles each week. She then uses 322.5miles/1 * 1gallon/21.5 miles (we have 1 gallon/21.5 miles because 1 gallon=21.5 miles and we have the gallon at the top to cross the miles out)=15 gallons. The cost per gallon is 2.85 (we add 2.85 for each gallon), and we have 15 gallons, so 2.85dollars*15l=42.75 dollars is our answer
The answer is square root of 36
because the square root of 36= 6
whereas the square roots of 37,38 and 39 give you recurring decimals

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%
I think the answer is 18!!!!!!
