First, subtract 10.2 from 8.5
8.5 - 10.2  = -1.7
Next, add -7.4 to -1.7
-7.4 (+) - 1.7 = -9.1
Your final answer is -9.1

Find the difference and write it in simplest form 7 3/8 - 2 7/9
Papessa [141]
Well first you have to turn the mixed number into a improper fraction.
7 2/8=59 over 8
2 7/9=25 over 9
Then u would multiply the 59 by 9 and 8 by 9 and u should get 531 over 72 and for the second fraction u should multiply the 25 by 8 and the 9 by 8 and you should get 200 over 72 as a improper fraction.
Then you have to subtract 531 over 72 by 200 over 72 and u should get 231 over 72 which is 4 and 43 over 72 when simplified.
The answer: 4 43/72
Hope this helps!!!!

Check my steps and for part b, the professor wants us to show are work and I don't know how to solve it by hand.
Ugo [173]
Part a is correct.

Part b can be done a couple ways.
1) Use binomial distribution. p = 0.2, n = 144
P(x>3) = 1 - P(x=0) -p(x=1) -p(x=2) -p(x=3)
where
P(x=k) = (nCk)p^k (1-p)^{n-k}

2) Assume a normal distribution with mean = 28.2, stdev = 4.8
z = \frac{4 - 28.2}{4.8} = -5.04
Look up z-value in normal table to find probability.

Hope that helps.
