Answer:
It is an enlargement because k=3 is larger than 1. Anything that equals less than one (ex. k=0.25) would be a reduction.
Step-by-step explanation:
The experiment probabilities are listed below:
One: 2 out of 20 = 2 / 20 = 0.1 or 10%
Four: 5 out of 20 = 5 / 20 = 1 / 4 = 0.25 = 25%
The theoretical probability of any single number is 1 out of 6 or about 17%.
The experimental probability for ones was less than and for fours it was greater than the theoretical probability.
Answer:
1) 4x + 4y = -8
x=-2-y
y=-2-x
2) 22 – 2y = 4
y=9
Step-by-step explanation:
To find the mean, aka average, we must add all the values of the table, then divide that sum by the number of values
