Answer:
Step-by-step explanation:
we have
This is the equation of a line in slope intercept form
where
---> the slope
----> the y-intercept
we know that
If the given line was shifted down 7 units, then the new y-intercept is equal to
The slope of the new line will be the same that the original line, because are parallel lines
so
The new equation is
14. 32 out of the 125 people surveyed preferred Company B. If the same proportion holds for the larger sample, we expect
... (32/125)×750 = 192 . . . . people would prefer Company B
15. There are a total of 45 marbles in the bag, of which 28 are NOT blue. The probability of drawing a NOT blue marble is 28/45.
16. We can desginate the point where the lines meet as O. Angles NOK and MOL are vertical angles, so are equal. The diagram tells you the measure of NOK is 90° + 15° = 105°, so that is the measure of (5x)°. The value of x is
... 105/5 = x = 21
17. Division by a fraction is the same as multiplication by its inverse.
