Hey there! :)
Answer:
h(x) = 3x² - 7x - 6
Step-by-step explanation:
Calculate h(x) by adding the two polynomials:
h(x) = f(x) + g(x):
h(x) = x² - 3x + 5 + 2x² - 4x - 11
Combine like terms:
h(x) = 3x² - 7x - 6
Answer:
(4x+2) +(3x+4)
Step-by-step explanation:
2(6x²+11+4)
(6x+3)+(3x+4)
12x²+16x+6x+8
12x²+22x+8
let me know if this helps guys my husband helped me with it he is good at math
According to the Central Limit Theorem the sum or average of at least 30 independent random variables with the same distribution is approximately normal. Therefore the answer is 'at least 30 measurements.'
Answer:
No solution
Step-by-step explanation:

Answer:
0.148 or 14.80%
Step-by-step explanation:
Mean overhead reach (μ) = 200 cm
Standard deviation (σ) = 8.9 cm
The z-score for any reach, X, is given by:

For a X = 209.30 cm:

A z-score of 1.045 corresponds to the 85.20th percentile.
Therefore, the probability that an individual distance is greater than 209.30 cm is:

The probability is 0.148 or 14.80%
