Answer: Option D, 16/21
Answer: The total cost of computer would be $719.95
Step-by-step explanation:
I use proportions for these types of problems so we begin with a proportion!
20/100=x/849
100x=16980
x=169.80
Then, after finding how much the discount is, we would subtract it.
849-169.80=679.20
Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.
6/100=x/679.20
100x=4075.2
x=40.75
Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!
Hope this helps! Good luck! (:
One possible probability is 1/10.
Since P(b) = 1/5, we know that there must be some multiple of 5 as the total number of markers.
There cannot be 5 markers in the box; if there is only 1 blue out of 5 markers, it is impossible for there to be any red markers and have a probability less than 1/5.
Using a total of 10 markers, there would be 2/10 blue to have a probability of 1/5. This means there would be 1/10 red. We know nothing about the number of green markers, so there can be as many as we want, in theory. This means the other 7 markers could be green.
Answer:
Draw a straight line that goes through the point (0,4) and (20,0)
Step-by-step explanation:
The y-intercept is equal to 4, since the function is already in y=mx+b form, where b is the y-intercept.
To find the x-intercept, we substitute 0 into y or in this case the f(x).
0 = -1/5 (x) + 4
1/5 x = 4
x = 20
The x-intercept is 20.
