For this case we propose a rule of three:
page ---------->
hour
x ---------------------------------> 1 hour
Where the variable x is the number of pages written in one hour.
![x = \frac {1 * \frac {3} {5}} {\frac {3} {10}}\\x = \frac {\frac {3} {5}} {\frac {3} {10}}\\x = \frac {10 * 3} {5 * 3}\\x = \frac {30} {15}\\x = 2](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B1%20%2A%20%5Cfrac%20%7B3%7D%20%7B5%7D%7D%20%7B%5Cfrac%20%7B3%7D%20%7B10%7D%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B%5Cfrac%20%7B3%7D%20%7B5%7D%7D%20%7B%5Cfrac%20%7B3%7D%20%7B10%7D%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B10%20%2A%203%7D%20%7B5%20%2A%203%7D%5C%5Cx%20%3D%20%5Cfrac%20%7B30%7D%20%7B15%7D%5C%5Cx%20%3D%202)
Thus, Ophelia types 2 pages in 1 hour.
Answer:
Ophelia types 2 pages in 1 hour.
Before the work was done, the cost was ...
($4/gal)*(8 gal)/(340 mi) = $32.00/(340 mi)
After the work was done, the cost was ...
($4/gal)*(7 gal)/(350 mi) = $28.00/(350 mi)
The savings is the difference of these costs:
(32.00/340 -28.00/350) $/mi ≈ $0.01/mi
After the mechanic worked on the car, it cost about $0.01 per mile less to run.
Answer: The graph for x cubed has a steep incline levels for a little before another steep incline
explanation: Since choice B is the only one that looks like this the answer is B
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and rotation.
Rigid transformations are transformation that produces an image with the same size, shape and angle as the original object. Rigid transformations are translation, rotation and reflection.
Dilation is not a rigid transformation.
All the transformations attached are rigid transformations.
Here we have to find the probability
. Now express the probability in terms of standard normal cumulative distribution function. That is
.
![P(-2.25](https://tex.z-dn.net/?f=%20P%28-2.25%3Cz%3C1.25%29%3D%5CPhi%281.25%29-%5CPhi%28-2.25%29%20)
Now you can look up the probability from the standard normal tables. Its value is
