Answer:
The percent of people, who either lives or eats on campus is 34 %.
Step-by-step explanation:
Let the total number of people be 100.
<em>Let set A be people who live in campus =</em><em> 56</em>
<em>Let set B be people who participate in meal = </em><em>62</em>
<em>Let set C(A∩B) be people who do both = </em><em>42</em>
According to set theory,
(A∪B) = A + B - (A∩B) = 56 + 62 - 42 = 76
Then either lives or eats is given by,
= (A∪B)-(A∩B) = 76 - 42 = 34
Thus, the percent of people, who either lives or eats on campus is 34 %.
Step-by-step explanation:
y cannot be determined from the information given
Answer:
C
Step-by-step explanation:
The correct answer for the question that is being presented above is this one: "xy / pm = 8." The equation that models the situation is this xy <span>/ pm = 8
</span>
<span>If x varies directly with the product of p and m and inversely with y:
</span><span>x = pm/y
</span>2 = 0.5*2 / 4
8 = 1
Then,
xy / pm = 8
