Year Sam Sally1: X (3/2)X-10002: (5/2)X-2000 2X-15003: X/5+1000 X/4+1400Total 37X/10-1000 15X/4-1100
Since their investments are known to be equal, we equate the two totals and solve for X.37X/10-1000=15X/4-1100(150-148)X/40 = 1100-1000X/20=100X=2000
So Sam invested $2000 the first year.Sally invested X/4+1400=1900 in the last year.
G(x) would be exponential. Additionally, the exponential is shifted down 5.
Answer:
11/15
Step-by-step explanation:
There are 8 marbles total. If they are being selected from twice with one missing, we could add 8 and 8 - 1 together to get the denominator for the probability.
8 + (8 - 1) = 15
We have to assume the first marble taken was red, so we will have 6 plus 6 - 1 red marbles to choose from for our numerator.
6 + (6 - 1) = 11
The probability of consecutively selecting two red marbles is 11/15.
