Answer:
B. 300 Copies
Step-by-step explanation:
So inplace of the copies you input the value x. Then, create an equation...
3,255= 13.75x -2.90x
3,255= 10.85x
Next you have to isolate x
3,255/10.85 = 300
so, 300=x
Answer: 4 x 4; 16 x 1; 2 x 8
Step-by-step explanation: You could find all the factors of 16 and done it that way. :)
Answer:
Step-by-step explanation:
a = 27
n = 20
d = -5
L20 = 27 + (n - 1)*d
L20 = 27 + (20-1)*_5
L20 = 27 + 19*-5
L20 = -68
Sum = (a + L)*n/2
Sum = (27 - 68)*20/2
Sum = -41 * 10
Sum = - 410
Yes they can and it depends on what the standard deviations are. The standard deviation is a measure of how close results are to the mean, a low standard deviations means the measurements are precise, so close to the mean. A high standard deviation means that measurements are more spread out. Saying that one set is more spread out than the other.
