(8 x 6) 8h =144
48+ 8h=144
144-48= 96
8h=96
96 divided by 8= 12
So he should have to work 12 hours at the restaurant. Hope this helps and sorry if it’s wrong!
Answer:
7.34×10⁰
Unless you're missing something in your question then that'd be it I guess... There isn't really a reason to put 7.34 in scientific notation though, so I'm assuming something isn't loading for me (or the question was changed).
Answer:
1. B
2. D
Step-by-step explanation:
(2x^2+6x-11)-(5x^2-x+7)
Pretend that there is a -1 in front of the second bracket
-1(5x^2-x+7)=-5x^2+x-7
2x^2+6x-11-5x^2+x-7
2x^2-5x^2+6x+x-11-7 ( combine like terms)\
-3x^2+7x-18
Answer: d. -3x^2+7x-18
Answer:
Null Hypothesis years
Alternative hypothesis years
Step-by-step explanation:
Hypothesis is a tentative guess. In a null hypothesis, we state that there's no statistical significance between the variables. For alternative hypothesis, it's stated that there's significant statistical relation between the provided variables. In this case, the null Hypothesis is years and the alternative hypothesis is years
We can decide to accept or reject either null hypothesis or alternative hypothesis
