Answer:
$3,000 was invested in the account that gained 13%
$17,500 was invested in the account that lost 10%
Step-by-step explanation:
Let the amount in both accounts be x and y
x for the first and y for the second
Adding both is 20,500
x + y = 20,500 •••••(i)
First account earned 13% profit
= 13/100 * x = 0.13x
Second account, a loss of 10%
= -10/100 * y = -0.1y
Total loss of -1,360
This is;
-0.1y + 0.13x = -1,360 •••••••(ii)
From i, x = 20,500-y
Insert this into ii
-0.1y + 0.13(20,500-y) = -1,360
-0.1y + 2665 -0.13y = -1360
-0.23y = -1360-2665
-0.23y = -4025
y = -4025/-0.23
y = 17,500
To get x, we have
x = 20,500 -y
x = 20,500- 17,500
x = 3,000
Answer:

Step-by-step explanation:
Answer:
a) Time in terms of AM or PM: Binary, qualitative and nominal (binary attributes are considered nominal)
b) Brightness as measured by a light meter: Ratio, quantitative and continuous.
c) Brightness as measured by people's judgments: Discrete, qualitative and ordinal (assuming they're chosen discretely)
d) Angles as measured in degrees between 0 and 360: Ratio, quantitative and continuous.
e) Bronze, Silver, and Gold medals as awarded at the Olympics: Qualitative, discrete and ordinal.
f) Height above sea level: Quantitative, continuous, ratio/interval (depending if it's seen as an arbitrary origin).
Answer:
1. -20 is the y intercept
2. 2x+4y=16
2x/2+4y/2=16/2
x+2y=8
x-x+2y=8-x
2y=-x+8
2y/2=-x/2+8/2
y=-x/2+4
4 is the y intercept
3. 2y+3x=7
2y+3x-3x=7-3x
2y=-3x+7
2y/2=-3x/2+7/2
y=-3
x/2+3.5
3.5 is the Y intercept
4. -3 is the y intercept
