Answer:
x<5
Step-by-step explanation:
the greater sign will firstly be changed to = for better solving so we obtain
3+9x=4(x+7)by opening bracket
3+9x=4x+28
9x-4x=28-3
5x=25
divide all through by 5x
we obtain
x=5
the greater sign change here
which is x<5
Answer:
Option A)
Confidence interval decreases
Step-by-step explanation:
If we increase the sample size, then,
- The standard error of the interval decrease.
- If the standard error increase, the margin of error of the interval decrease.
- If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.
Thus, the correct answer is
Option A)
Confidence interval decreases
