Answer:
Per phone, there is an expected profit of $206.69. This means that the company can expect a profit in the long term for their smart phones.
Step-by-step explanation:
Ten out of every 75 phones they sell are having issue with the touchscreen
10/75 = 0.1333
0.1333 of the phones have issues with the touch.
The other 1-0.1333 = 0.8667 do not have issues with the touch.
Check whether the company can expect a profit in the long term for their smart phones.
0.1333 of the time, loss of $400.
0.8667 of the time, profit of $300.
So the expected earnings per phone will be:
E = -0.1333*400 + 0.8667*300 = $206.69
Per phone, there is an expected profit of $206.69. This means that the company can expect a profit in the long term for their smart phones.

The reason I am typing all of this is because it says it needs more characters. Not the answer, though.
Answer:
5v+35 = 5(v+7)
Step-by-step explanation:
5(v+7) = 5v+35
When two figures are similar, one is the scaled version of the other.
This means that all the correspondant sides of the two figures are in the same proportion, i.e. there exists a number such that every side of the figure on the right is computed by multiplying the correspondant side of the figure on the left by
If this is the case, the two areas are also proportional, but the coefficient is squared: this means that the area of the figure on the right is not times the area of the figure on the left, but rather times.
We are given two correspondant sides, so we can deduce the scale factor: the side of 12 inches is the result of multiplying the 9 inches factor by the scale factor, so we have
.
Now let's use the result about the areas: the area of the figure on the left, , is given by
