You just cross multiply and then simplify
Answer:
(a) 71.00%
(b) 63.00%
Step-by-step explanation:
No optional features = 0.29
One feature = 0.34
Two features = 0.37
(a) The probability that an order requests at least one optional feature is 100% minus the probability of an order requesting no optional features:
(b) The probability that an order does not request more than one optional feature is 100% minus the probability of an order requesting two optional features:
Well, in the first one, 2 degrees below zero is -2 degrees, and then it says that it dropped 14 degrees, which means it dropped -14 degrees, so to know the total amount it dropped you would just have to add -2 plus -14 which is -16 degrees, so your answer for the first question would be the last answer, -16 degrees.
For the second question, just know that whenever a negative number is BY ITSELF in parentheses, that means it is used like a positive number in the equation. So (-12) automatically becomes 12. Now, since the problem is asking for a SUM, (the answer to an ADDITION problem; when you add instead of subtract), you would turn that minus symbol to a plus symbol, and add normally to get your final answer; 30 + 12 = 42. To check if this is correct, just type in <span>30 – (–12) to a calculator and you'll get the same answer! :D
Hope this helps! :3</span>
Answer:
Step-by-step explanation:
Alina=2x---eq(1)
Asim=5x----eq---(2)
So,we get
2x+5x=210
7x=210
x=30
Now,Putting '30' in eq 1 and eq 2
2*30=60
5*30=150
Therefore Alina got 60 Rs while Asim got 150 Rs
