I hope you can understand my messy handwriting
Infinite solutions they are a set of equations that express a set of quantities
Answer:
(1) 0.4207
(2) 0.7799
Step-by-step explanation:
Given,
Mean value,

Standard deviation,

(1) P(X ≥ 17.5) = 1 - P( X ≤ 17.5)




( By using z-score table )
= 0.4207
(2) P(14 ≤ X ≤ 18) = P(X ≤ 18) - P(X ≤ 14)



= 0.9918 - 0.2119
= 0.7799
To subtract 3/4 - 2/3
1. must find the LCD( Least Common Denominator; the smallest multiple of the denominators of two or more fractions)
2. Combine them
Exact form:
1/12
Decimal form:
0.083
So in fraction form your answer should be:
1/12
Hope i helped! :)
