Answer: C. At the α=0.05 significance level, they should conclude that more than 50% of adults support the tax increase.
Step-by-step explanation:
Given: Null hypothesis: 
Alternative hypothesis: 
p-value = 0.033
If the p-value is greater than alpha (p > . 05), then we fail to reject the null hypothesis.
If α=0.01 , then p-value > α i.e. we fail to reject the null hypothesis.
Conclusion: Exactly 50% of adults support the tax increase.
If α=0.05 then p-value < α i.e. we reject the null hypothesis.
Conclusion: more than 50% of adults support the tax increase.
Thus, Correct option: C .
Answer:
Yes, if x < -1
Step-by-step explanation:
Is x + 5 less than 4?
x + 5 < 4
x < 4 - 5
x < -1
Yes, if x < -1

Hope I helped, also, I used the math thingy, which I haven't used before, so I'm not sure quite how this turned out, well, I guess we will see in a minute! But if it does not work I can try it just typing regularly.
Answer: 1. -11=x 2. 24=x 3. x=-12 4. -7 5. x=7
Step-by-step explanation: The answer to first one can be calculated by seeing the - as a -1.
-5 = x - (-6)
-5=x+6
Then subtract 6 from both sides.
-5=x+6
-11=x
The answer to the second can be found simply by dividing both sides by 1.25.
- 30=1.25x
-30/1.25=1.25x/1.25
24=x
The third one can be solved by as we said before dividing both sides by -6.
-6x=72
-6x/-6=72/-6
x=-12
The fourth one can be found again by using division on both sides.
-4.9=0.7x
-4.9/0.7=0.7x/0.7
-7=x
Finally we solve the last one by again doing the same thing dividing both sides by 0.45.
3.15=0.45x
3.15/0.45=0.45x/0.45
7=x
Hope this helps!
