Answer:
Step-by-step explanation:
Given that among 500 freshmen pursuing a business degree at a university, 315 are enrolled in an economics course, 213 are enrolled in a mathematics course, and 123 are enrolled in both an economics and a mathematics course.
From the above we find that
a) either economics of Math course is
![315+213-123 =405](https://tex.z-dn.net/?f=315%2B213-123%20%3D405)
Out of 500 students 405 have taken either Math or Economics
Hence
c) student who have taken neither = ![500-405 =95](https://tex.z-dn.net/?f=500-405%20%3D95)
Exactly one course is either math or economics - both
= ![405-123 = 282](https://tex.z-dn.net/?f=405-123%20%3D%20282)
|x| because just Google it if I'm wrong
1) 3 x 4 = 12 + 3 = 15/10= 1.5
1.5/4 =<em> 3/8 drink mix for one drink</em>
2) 22/8
22/3=7.3
<em>so 7 cups of drinks </em>
Take 3 out of both of them
3(5x+2)
<span>(a) the slope of curve is calculated from the derivative of the curve expression y=5/x. In this problem, the slope m=-5/(a^2).
(b) x=1, y=5,and m=-5, the tangent line is y-5=-5*(x-1).
x=4, y=5/4, and m=-5/16, the tangent line is y-5/4=-5/16*(x-4)</span>
