Thats four questions, but okay :) 1.) 1 16/32 is just an hour and a half, and 1 2/8 is a hour and 15 minutes. that adds up to 2 hours and 3/4 or 2 hours and 45 minutes. 6-2 3/4 =3 1/4 hours, or 3 hours 15 minutes. 2.) convert the 1/3 and 2/5 into 10/30 and 12/30 so they have the same denominator, add them. that equals 22/30. now convert the 9/10 into 27/30 for easy subtraction. 27/30 minus 22/30 is 5/30, simplify that and it is 1/6. so betty needs a 1/6 of a gallon more. 3.) 32 6/12 is just 32 and 1/2. and thats 1/5 of his stuff. so take 32.5 and multiply it by 5, which equals 162.5 minutes. that is 2 hours 42 minutes, and 30 seconds. 4.) take 6 3/8 and multipy that by three for one week. that is 19.125. now multipy that by three since there are three weeks. that equals 57.375 which as a fraction is 57 3/8. so he would run 57 and 3/8 miles in three weeks of training. sorry about my spelling, im ust trying to type fast so you can get this fast. :)
F(2x-5)=14x-35
G(4x+3x)=14x-5
Answer:
The probability that a randomly selected programmer major received a salary less than 38000 is 0,3085
Step-by-step explanation:
We will assume that the salaries are Normally distributed. Lets call X the salary of a random major programmer in dollars. We want the pprobability of X being less than 38000. For it, we will standarize X. Lets call W the standarization, given by the formula
Lets denote 
the cumulative distribution function of the standard normal variable W. The values of are well known and they can be found in the attached file. Now, lets calcualte the probability of X being less than 38000 using
Since the density function of a standard normal random variable is symmetric, then 
The probability that a randomly selected programmer major received a salary less than 38000 is 0,3085.
