Answer:
- 6, 9 and 27
Step-by-step explanation:
Substitute a = - 3 into the expressions and evaluate
(a)
2a = 2(- 3) = - 6
(b)
a² = (- 3)² = 9
(c)
3a² = 3(- 3)² = 3(9) = 27

Answer:
a. Probability distribution is given below
Scores Ex, x. 1 2 3 4 5
P(X=x). 0.05 0.09 0.03 0.42 0.41
b. Scores mg, Y 1. 2. 3. 4. 5
P(Y=y). 0.04. 0.1. 0.12 0.46 .28
c. probability that a randomly selected senior executive will report a job satisfaction score of 4 or 5.
P(4 or 5) =p(x=4) +p(x=5)
= 0.42 + 0.41=0.83
Answer:
There was an increase of 176.92 % of life expectancy
Step-by-step explanation:
To find this solution, we need to compare the life expectancy in the Stone age and in 2016
Stone age
26 years. (this represents 100%)
2016
72 years
We apply a rule of three
26 years ------------------100%
72 years --------------------x
(72/26)*100% = 276.92 %
276.92 % - 100% = 176.92 %
There was an increase of 176.92 % of life expectancy
