1. Answer: given: an average of 28 pounds
a.
Find z values corresponding to 27 and 31:
z=%2827-28%29%2F2=-1%2F2=-0.5
z=%2831-28%29%2F2=3%2F2=1.5
Find the area between z+=+-0.5 and z=+1.5
Table E gives us an area of 0.9332-0.30=0.6247=> The probability is 62.47%
b.
Find z values corresponding to 30.2
z=%2830.2-28%29%2F2=2.2%2F2=1.1 Find the area to the right of z+=1.1
it gives you an area of 0.1357=> The probability is 13.57%

Answer: 
Step-by-step explanation:
- Original equation:
- Subtract 5x from both sides of the equation:
- Divide both sides of the equation by -1:
- Divide both sides of the equation by 3 to get y on the left, leaving the equation in
form: 
- Evaluate. Slope is equal to m in this form, so the slope is
