The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 3. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 59 and 62
Answer:
About 34%
Step-by-step explanation:
Given that :
Mean, m = 59 ; Standard deviation, s = 3
Bulb replacement numbering between 59 and 62
For, x = 59
Zscore = (x - m) / s
Z = (59 - 59) / 3 = 0
For x = 62
Z = (62 - 59) / 3 = 1
P(Z < 1) - P(Z < 0)
0.84134 - 0.5
= 0.34134
About 34%
How do you find the fraction between 9/5 and 10/5?
Answer:
Step-by-step explanation:
to do something like this, you could just multiply both sides by 2. So now, you have 18/10, and 20/10. The one in between that would be 19/10

There are 1,000 meters in 1 kilometer. How many kilometers are in 3,600 meters?
HELP
Answer:
A. 3.6 kilometers
Step-by-step explanation:
1000 meters = 1 km
3600 meters = x km
Set as a ratio:
1000 : 1 = 3600 : x
Then divide:
[tex]\frac{3600}{1000} = \frac{x}{1} = x[/tex]
so 3600/1000 = 3.6 = x
3.6 km

One angle of a parallelogram measures 65 degrees. what is the measure of the angle opposite it
Answer:
[tex]65\textdegree[/tex]
Step-by-step explanation:
Opposite angles of a parallelogram are congruent and thus have the same measure, so if one angle of a parallelogram measures [tex]65\textdegree[/tex], then the angle opposite it will also have the same measure of [tex]\bold6\bold5\textdegree[/tex]. Hope this helps!

How do I simplify this
Answer:
96/18
Step-by-step explanation:
To simplify you need to turn it into an improper fraction. This means that the numerator (the number on top) is greater than the denominator (the number on the bottom). The improper fraction form of 5 6/18 is 96/18. I believe this is the answer to your question.
I hope this helps you!

Using the graph below, what would the input (x-value) need to be for an output (y value) of 1?
Answer:
X = 2
Y = 1
The graph intersects at the exact point of (2,1)
The value of x or the input value is 2 for which the output or the value of y is 1.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have a graph of a line shown in the picture
As we can see the line passes through the points (3, 3) and (0, -3)
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The equation of the line passes through the points:
( y + 3) = (-3-3)/(0-3)[x - 0]
y + 3 = 2x
y = 2x - 3
Plug y = 1
1 = 2x - 3
2x = 3 + 1
2x = 4
x = 4/2
x = 2
Thus, the value of x or the input value is 2 for which the output or the value of y is 1.

If L(2, 7) is an endpoint of a line segment, and M(8, 3) is the midpoint, find the other endpoint of the segment.
Answer:
Step-by-step explanation:
From L to M,
change in x-coordinates = 8-2 = 6
change in y-coordinates = 3-7 = -4
Extrapolate from M(8,3) to find the other end of the segment:
8 + 6 = 14
3 - 4 = -1
Endpoint of segment: (14,-1)
