(a) 2.49 * 6 = 14.94 <== what they spent on goodie bags
(b) 150 for 8 hrs = 150/8 = 18.75 per hr
(c) 182.53 - (150 + 14.94) = 182.53 - 164.94 = 17.59...they spent 17.59 more
This is not the best question I've ever seen. The wording is the problem, and it's not your fault. The melting point of Krypton is about - 160 oC. It means that numerically the melting point of Krypton is 4 times lower than that of mercury.
Krypton = 4*M
M = - 39
Krypton = 4*-39
Krypton = - 156o C
Now you want to make it something like K(1/4) = - 39 which would be fine. You can't use - 1/4. If you do, your answer will come out to be + 156 which is not what you mean. If this was a multiple choice question, your answer would be the second best one.
The coordinate of point Y such that the ratio of MY to YJ is 2:3 is 6.4
<h3>How to determine the point?</h3>
The complete question is added as an attachment
The coordinates are given as:
M = 2
J = 18
The ratio is given as:
Ratio = 2 : 3
The location of the point Y is then calculated as:
Y = Ratio * (J - M)
This gives
Y = 2/(2 + 3) * (18 - 2)
Evaluate
Y = 2/5 * 16
This gives
Y = 6.4
Hence, the coordinate of point Y such that the ratio of MY to YJ is 2:3 is 6.4

Answer:
$3220
Step-by-step explanation:
A man invests $1000 in a 12-month certificate of deposit paying 8% interest.
So, after 1 year his money will become from the certificate deposit = $
Again the man invest $2000 in municipal bonds that pays 7% a year.
So, after 1 year his money will become from the municipal bond = $
Therefore, total yearly return from both the above investment will be $[(1080 + 2140) -(1000 + 2000)] = $220 (Answer)
Answer:
.
Step-by-step explanation:
The z-score for a normal distribution is calculated using the formula:
.
From the question, the distribution has a mean of 50.
and the standard deviation is
.
For a z-score to be negative, then,
.
.
.
.
.
.
Any value less than 50 will produce a negative z-score
