Answer:
This equation does have real solutions contrary to your question. They are OR
.
Step-by-step explanation:
In order to prove this has real number solutions, we simply need to use the quadratic formula. To do this, we first need to solve for 0.
2x^2 + 18x = 10
2x^2 + 18x - 10 = 0
Now that we have this and they are all factors of 2, we can divide everything by 2 for ease.
2x^2 + 18x - 10 = 0
x^2 + 9x - 5 = 0
Now we can use the quadratic equation to solve. Remember that A = 1 due to the coefficient of x^2, B = 9 as the coefficient of x and C = -5 as the constant.
OR
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 .
