Answer: the normal curve can be used as an  approximation to the binomial probability considering the following condition: when the sample is large, in this case n=112

Step-by-step explanation:

for a binomial experiment to be approximated to normal distribution, the following conditions must be present:

i.  sample size must be large, in this case sample size is 112

ii.  the mean must be equal to np,where n is sample size and p is probability  of success

iii.  the standard deviation must be equal to npq,where q is the probability of failure

1)

\dfrac{3}{4}  + 5 -  \dfrac{1}{2}  = \dfrac{3}{4}  +  \dfrac{20}{4} -  \dfrac{2}{4}  =  \dfrac{21}{4}  = 5 \dfrac{1}{4}

2)

\dfrac{2}{3}  +  {2}^{3}  -  \dfrac{1}{3}  =  \dfrac{2}{3}  +  \dfrac{24}{3}  -  \dfrac{1}{3}  =  \dfrac{25}{3}  = 8 \dfrac{1}{3}

3)

- 15 + 6x - 19 - 20x =  - 14x - 34

4)

- 7x - 2 - 9y + 10x = 3x - 9y - 2

5)

14 + x = 18 \\ x = 18 - 14 \\ x = 4

6)

- 5x =  - 15 \\ x =  - 15 \div ( - 5) \\ x = 3

7)

- 2x + 8 = 18 \\  - 2x = 18 - 8 \\  - 2x = 10 \\ x = 10 \div ( - 2) \\ x =  - 5

8)

3x + 18 - 8x =  - 17 \\ 3x - 8x =  - 17 - 18 \\  - 5x =  - 35 \\ x =  - 35 \div ( - 5) \\ x = 7
