Answer:
it is 2
Step-by-step explanation:
Answer:
8) x = 5.41
9) x = 45
10) x = 2.25
Step-by-step explanation:
8) 17/15 = 10/(2x-2)
150 = 34x - 34
reduce:
34x = 184
x = 5.41
9) 6/16 = (x-12)/(2x-2)
16x - 192 = 12x - 12
reduce:
4x = 180
x = 45
10) (x-9)/15 = (2x-9)/10
10x - 90 = 30x - 135
reduce:
20x = 45
x = 2.25
To find the mean (fair share/average) of the data set, you will combine all the numbers (add) and then split them into the same number of groups you started with (divide by 10).
1320/10 = 132
The mean is 132.
Y - 5 = -2x - 4
Add 5 on both sides.
y = -2x + 1
y = -2x + 1 is in simplest form.
The current is doubled. Ohm's law states that V = IR, therefore, if the voltage is doubled, aka 1.5 to 3V, than assuming resistance stays constant, the current must double.
