13/15 - <span>1/5 </span>
<span>common denominator is 15 </span>
<span>Multiply numerator and denominator of 1/5 by 3 = 3/15 </span>
<span>13/15 - 3/15 = 10/15 </span><span>= 2/3
2/3 is your answer.</span>
Answer:
Lines 3 and 4
Step-by-step explanation:
Let's examine the slope of each of the given lines to have the exact value and be able to answer the question. We use the definition of: 
Line 1: 
Line 2: 
Line 3: 
Line 4: 
Line 5: 
Therefore the lines that have slope strictly greater than 1 and less than 2 are:
Lines 3 and 4
Hip Breadths and Aircraft Seats
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. (Accommodating 100% of males would be too expensive.) Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.0 in. Find P 98. That is, find the hip breadth for men that separates the smallest 98% from the largest 2%.
