Answer:
orange juice 0.80 dollar
Bagel 1 dollar
coffe 0.60 dollar
Explanation:
We construct the equation system:
We subtract one from another to get an expression without C:
1.5A+1.2B+C - (A+B+C) = 3 - 2.40
0.5A + 0.2B = 0.6
Then, we solve in the first part to express B as an expression of A
considering the coffe is worth half of the new cost of A
C = 1.5A / 2 = 0.75A
A + B + C = 2.40
A + B + 0.75A = 2.40
B = 2.40 - 1.75A
And now we replace in the other expression to get A:
0.5A + 0.2(2.40 - 1.75A) = 0.6
0.5A - 0.35A + 0.48 = 0.60
0.15A = 0.12
A = 0.12/0.15 = 0.8
Now we solve for C:
C = 0.75A = 0.6
Last, for B:
A + B + C = 2.40
0.8 + B + 0.6 = 2.40
B = 2.40 - 0.8 - 0.6 = 1
They must have good communication manners and be polite
Answer:
a. H0 : U ≥ 15
Ha : U < 15
b. Type I error is incorrectly conclude that the pain is reduced in less than 15 minutes.
c. Type II error is fail to conclude that time for pain reduction is less than 15 mints when actually its less than 15 minutes.
Explanation:
Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis.
Type I error is one in which we reject a true null hypothesis.
Type II error is one in which we fail to reject the null hypothesis that is actually false.
Answer:
Pure discount
Explanation:
Cindy is taking a pure discount type of loan. A pure discount loan is the promise to pay a certain sum of money in the future in exchange for borrowing money today. Cindy gets money today and repays a single lump sum at a future date. A pure discount loan is where the principal is paid back at a future date without any periodic interest payments
