Answer:
A. $1,710
B. Yes, probably.
Step-by-step explanation:
Assuming that a 10% decrease in energy use leads to a 10% decrease in the electric bill:
We'll want to find the value which is 10% less than the original value, i.e., the bill cost which is 90% of the original bill.
90% = 0.9
Since the original bill was $1900, we can just multiply 1900 by 0.9:
Answer: A bill of $1,710 would equal a 10% decrease.
Since $1,672 is less than that, then they have decreased their energy use by more than 10% which is likely a success.
Answer: Yes, probably.
Answer:
Non-mutually exclusive
Step-by-step explanation:
both events can happen simultaneously... 3 is an odd number, events A and B have a common outcome.
It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.
60 is the base OK. I think am right
797,100 deaths x
---------------------------------- = -------------------------
350,000,000 people 100,000 people
or:
797,100 deaths x
--------------------------- = -----------------
3500 people 1 people
Result: 228 deaths per 100,000 people
Answer:
The range is 5.
Step-by-step explanation:
You can deduce this by concluding all other statements are true, or by calculating the range. 10 - 1 = 9
