Whatever is inside parentheses first [g(x)], is what you would evaluate first, then after that, you would substitute that answer into the f(x) function for EVERY "X" YOU SEE:
[2x² + 5]² + [2x² + 5] + 2
[2x² + 5]² + [2x² + 7]↓
This is your final answer. You get it?
A) The empirical rule tells you the probability of being within 1 standard deviation of the mean is 68%.
b) The probability that the sample mean falls within 3 standard deviations* of the mean is 99.7%.
___
* The standard deviation of the sample mean is 1/√9 = 1/3 of the standard deviation of an individual sample. Hence the same limits (90-110) now cover 3 standard deviations of the sample mean.
Answer:
x + 3 + 
Step-by-step explanation:
Divide using Synthetic division
dividing by ( x - 3)
Using 0 to represent the x- term
3 | 1 0 4
↓ 3 9
+ +
------------------
1 3 13 ← remainder
Thus
= x + 3 +
Answer:
y = 5
Step-by-step explanation:
slope = Δy / Δx = (5 - 5) / (0 - 2) = 0
y = Ax + B
y = 0x + 5
