Answer:
6x^7 + 12x^6 + 3x^5
Step-by-step explanation:
Simplify the expression.
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is
</span>E) 8±0.98
Answer:
a=28/5 or 5.6
Step-by-step explanation:
2a/7=a-4
Multiple both sides of the equation by 7
2a=7a-28
Subtract 7a from both side
2a-7a=-28
Like Term
-5a=-26
Divide -5 from both side
a= 5.6
Answer:
Choice A
