1. -8=1(x+4)
2. -8=x+4 because when you multiply the things in parentheses by one it stays the same, 1 times x = 1x or just x and 1x4= 4
3. -8-4=x because you need to get x by itself so you move the positive 4 to the opposite side which makes it negative
4. -12=x because -8 + -4 = -12 which is x :)
Answer:
Option A. f(x) = 2*(0.25)^x
Step-by-step explanation:
As x increases f(x) decreases so the base of the exponential part is < 1.
So it looks like (0.25)^x is included in the function. When x = 0, f(x) = 2.
Now (0.25)^0 = 1 so 2 * (0.25)^0 will make f(x) = 2.
The answer is f(x) = 2*(0.25)^x.

Answer:
0.0668
Step-by-step explanation:
Assuming the distribution is normally distributed with a mean of $75,
with a standard deviation of $12.
We can find the z-score of 78 using;
Using our normal distribution table, we obtain the area that corresponds to 0.25 to be 0.9332
This is the area corresponding to the probability that, the average is less or equal to 78.
Subtract from 1 to get the complement.
P(x>78)=1-0.9332=0.0668
