Answer:
y = -5/8
x = 7/24
Step-by-step explanation:
elimination
12x + 4y = 1 | ×1 |
6x - 2y = 3 | ×2 |
12x + 4y = 1
12x - 4y = 6
_________--
8y = -5
y = -5/8
elimination
12x + 4y = 1 | ×1 |
6x - 2y = 3 | ×2 |
12x + 4y = 1
12x - 4y = 6
_________+
24x = 7
x = 7/24
<u>ANSWER: </u>
In a data set with a range of 55.4 to 105.4 and 400 observations.86 lies in the 49th percentile.
<u>SOLUTION:
</u>
Given, in a data set with a range of 55.4 to 105.4 and 400 observations.
There are 176 observations below the value of 86, and we need to find the percentile for 86.
We know that, percentile formula =
Percentile of 86 =
Since, we cancelled 400 with 100 we get 4 , hence above expression becomes,
= 49
So, percentile of 86 = 49
Hence, 86 lies in the 49th percentile.
27.24 x .15 = 4.086 which is 4.09
27.24 bill plus time of 4.09 = 31.33
Answer:
$652.5
Step-by-step explanation:
The interest earned in one year would be $130.50 because 1450*.09= 130.50
so then the interest for 5 years would be 652.5 because 130.5*5=652.5
