Answer is 3.78, since the positive number is bigger, so the answer is positive too
Answer:
19.
Step-by-step explanation:
Number of ways the first 4 databases can be selected = 9C4 = 126
Probability that it is in 2 of the first 4 = 5C2 / 126 = 10/126
Probability that it is in 3 of the first 4 = 5C3 / 126 = 10/126
Probability that it is in 4 of the first 4 = 5C4 / 126 = 5/126
Probability that it is in at least 2 of the first 4 = 10/126 + 10/126 + 5/126 = 25/126
Answer:
48x
PEMDAS: Do the exponent first 4 times 4 is 16 times that by 3x to get 48x.
Answer:
As x gets bigger, y is now getting smaller.
Step-by-step explanation:
A fancy way to say this is that the function y = 2-x is what we get when we reflect y = 2x across the y-axis.
