Write the thing spaced out:

4a    <u>-5b</u>     +6ab     <u>-8b</u>      -3a
The signs (+,-) are assigned to the numbers it is in front of.

We minus the "like" terms:
4a - 3a = 1a
<u>-5b  - 8b = -13b
</u>+6ab = +6ab

Put them all together:
1a - 13b + 6ab

The answer for, "4a - 5b + 6ab - 8b - 3a" = "1a - 13b + 6ab"

drek231 [11]

Answer:

95% Confidence interval:  (96.06,103.94)

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 85

Sample mean, \bar{x} = 100

Sample size, n = 30

Alpha, α = 0.05

Population standard deviation, σ = 11

95% Confidence interval:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

100 \pm 1.96(\frac{11}{\sqrt{30}} ) = 100 \pm 3.94= (96.06,103.94)

(96.06,103.94) is the 95% confidence interval for  the population mean test score.
