Answer:
39.9
Step-by-step explanation:
A good trick to remember is SOH CAH TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we're given an angle and the opposite side, and we want to find the adjacent side. So we need to use tangent.
tan 31° = 24 / x
x = 24 / tan 31°
x ≈ 39.9
If you do 6-8 you get -2 so all you have to do is add the 3 and its negative. the answer is .............-32
Jeremy should use coupon 2 because when you multiply both the sweaters (36) by .25 you get 9, and then you subtract 36 by 9 which is 27.
But when you use coupon 1 you multiply 18 by .40 which is 7.20 where you subtract 18 by 7.20 which is 10.80. You then add 10.80 with 18 which is 28.80.
I don't even know what the question is but I found the same problem and this was the answer
Answer:
2.65
Step-by-step explanation:
Multiply each payout by its probability, then add those products.
See the attached image.
The first column has the payouts. The second column has the probabilities. The third column has the results of multiplying a payout by its probability.
The sum of the entries in the third column is 2.65
2 = coefficient
e = variable
- = operation
f = variable
2e = 2 × e
f subtracted from the product of two and e
