Students planted 4(2x+3y) amount of trees on saturday and then 3(5x+4) amount of trees on Sunday. What is the total amount of tr

algol [13]

We have to add the amounts:

4(2x+3y) + 3(5x+4)

First, though, we have to distribute:

4*2x + 4*3y + 3*5x + 3*4
8x + 12y + 15x + 12

Now we just need to simplify:

23x + 12y + 12

The students planted 23x + 12y + 12 trees total.

Answer:

68% Confidence interval = [4.5752, 4.5848]

95% Confidence interval = [4.5688, 4.5918]

Step-by-step explanation:

Sample mean (X) = 4.580

Sample Standard Deviation (S) = 0.01065

Sample size (n) = 6

$T_{(5)}$ for alpha/2 0.84 = 1.1037

$T_{(5)}$ for alpha/2 0.975 = 2.5706

68% Confidence interval = $[x-T_{(5)}\frac{S}{\sqrt{n}}, x+T_{(5)]\frac{S}{\sqrt{n}}]$ = [4.5752, 4.5848]

95% Confidence interval = $[x-T_{(5)}\frac{S}{\sqrt{n}}, x+T_{(5)}\frac{S}{\sqrt{n}}]$ = [4.5688, 4.5918]
