Lets look at the hours they are open from. 9 am - 4:30 pm which is 7 and a half hours a day. Now we multiply 7 1/2 by the number of days they are open, which will be 7 1/2 * 255 = 1,912.5. This means that the library is open 1,912 1/2 hours a year.
I hope I've helped! :)
Answer:
The standard deviation would have to be 0.05.
Step-by-step explanation:
We can solve this problem using the 68-95-99.7 rule for normal distributions:
The rule states that:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviations of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
What would the value of σ have to be to ensure that 95% of all readings are within 0.1° of μ?
This means that 2 standard deviations would need to be within 0.1 of the mean. So



The standard deviation would have to be 0.05.
Answer:
<em><u>In the graph locate the point (3,0) and draw a line parrallel to Y-axis passing through (3,0) .</u></em>
<em><u>Then your line will cut the graph of f(x) at some point, that point's y-coordinate will be your value of f(3).</u></em>

FOIL stands for first, outer, inner, and last.
So, you multiply the first terms together, the outer terms together, the inner terms together, and then the last terms together.
(b+3)(b-9)
b^2-9b+3b-27 Then simplify
b^2-6b-27
Answer:
The Answer is: B.
Step-by-step explanation:
The form of the equation is:
f(x) = ab^x
When b is greater than 0 and less than 1, the function is an Exponential Decay Function.
B. is f(x) = (.08)^x
In this case, a = 1
