Hey there! I'm happy to help!

Let's call this number n. Here is the info we can write about it. Remember that to write as a percent as a decimal you divide by 100.

n-0.16n=159.6

We combine like terms.

0.84n=159.6

We divide both sides by 0.84

n=190

Have a wonderful day! :D

An online camping gear company ships two camping tents to a customer. Each tent weighs 6 lb 10 oz,. What is their combined weigh
dezoksy [38]
<em>The answer is 13 pounds (lbs.) and 4 ounces (oz.). There are 2 tents and each is 6 pounds. Add those together and that is 12 pounds. All that is left is to add the ounces. 10+10=20. Since there are only 16 ounces in a pound and we have 20 ounces, we add an extra pound and are left with 4 ounces. </em>

Please help last question and u get 15 points

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%
