Please help!!!! I’m unsure of the answers
igomit [66]

Answer:

table:

.1, .25, .35, .2, .1

p(x=4) = .1

p(x<2) = .35

p(3≤x≤4)= .55

1.95, 1.12

Step-by-step explanation:

this is kind of hard to read, but i think i've got it

mean:

0*.1+1*.25+2*.35+3*.2+4*.1= 1.95

The second moment:

0²*.1+1²*.25+2²*.35+3²*.2+4²*.1= 5.05

the variance is the second moment minus the first moment squared (first moment is the mean) and then the standard deviation is the square root of the mean

5.05-1.95²= 1.2475 √1.2475= 1.1169 or 1.12

                                                           1 gal

Mult this result by 6 gal.  This gives you 18 oz, approx.


Now let's look for a more exact solution:

2.75 oz      19 gal
---------- * ---------- = 17.4 oz.  The 18 oz estimate was close.
