Answer:
The answer to your question is: -2x -5
Step-by-step explanation:
h(x) = x -3
g(x) = 3x + 2
find (h -g)(x)
Just
(h-g)(x) = x - 3 - (3x + 2)
= x - 3 - 3x - 2 like terms
= -2x -5 result
Answer:
Null hypothesis: H0: The dictator's negative are equal to 70%.
Alternative hypothesis: Ha: The dictator's negative are less than 70%.
Step-by-step explanation:
The null hypothesis always contains equality sign and alternative hypothesis usually contains claim made by researcher. Here, in the given scenario, the political committee of a dictator wants to keep negatives below to 70%. So, the null hypothesis will be that the negative are equal to 70% while alternative hypothesis will be that the negative are less than 70%.
Thus, the hypotheses for the given scenario are
Null hypotheses: H0: The dictator's negative are equal to 70%.
Alternative hypotheses: Ha: The dictator's negative are less than 70%.
Speed=slope=∆distance/∆time
Part1:
(20-60)/(1-0)=-40mph
Part2:
(0-20)/(3-1)=-20/2=-10mph
