Let us say that:
x = invested at 7%
y = invested at 8.5%
and that:
<span>x + y = 12,000</span>
We can also say that:
0.07 x + 0.085 y = 900
Therefore:
0.07 x + 0.085 (12000 – x) = 900
0.07 x + 1020 – 0.085 x = 900
- 0.015 x = -120
x = $8000
so y is:
y = 12000 – 8000
y = $4,000
$8000 is invested at 7% annual interest while $4000 is invested at 8.5%
Where are the figures, can you upload a Pic of the figures so that I can answer your question
Answer:
2/27
Explanation:
The two events, drawing a blue marble out of each bag, are independent. This means to find the probability of both occurring, we multiply them.
In the first bag, there are 5 blue marbles out of 15 total. This makes the probability 5/15, or 1/3.
In the second bag, there are 2 blue marbles out of 9 total. This makes the probability 2/9.
Together, the probability of both events happening are:
1/3(2/9) = 2/27
