Answer:
$9,840
Step-by-step explanation:
Let the money earned from college be 'x'.
Given:
Total money earned from the two jobs = $50,450
Money earned at the store = 1250 + 4(Money earned at college)
∴ Money earned at the store = 
Now, total money earned by Erica is the sum of money earned at store and college. Therefore,
Total money = Money at store + Money at college
Therefore, the money earned by Erica from her job at the college is $9,840.

Answer:
I think its A because with B and C your reflecting it across the y-axis and its asking to reflect it over the x-axis while D, is a reflection and a translation

Answer: a) The probability that the first marble is red and the second is white.
P = (9/23)(8/22)
b) The probability that both are the same color.
P = 2R + 2W + 2B
P = (9/23)(8/22) + (8/23)(7/22) + (6/23)(5/22)
c) The probability that the second marble is blue.
P = (17/23)(6/22) + 2B (Need to consider both are Blue)
P = .202 + (6/23)(5/22) = .202 + .059 = .261
23 marbles
9/23*8/22, since there is one less marble
That is 72/506 or 0.142
-------------------------------
same color
9/23*8/22 (red)
8/23*7/22 (white)
6/23*5/22 (blue)
The denominator is 506
The numerator is 72+56+30=158
158/506=0.312
----------------------------------------
Second marble blue:
3 possibilities
first red and then it is 9/23*6/22
first blue and then it is 6/23*5/22
first is white and then it is 8/23*6/22
Denominator is 506
Numerator is 54+30+48=132
132/506=0.261
