Consider the Venn diagram shown in the picture.
173 is the number of students enrolled in both Business Maths and Statistics.
Let a be the number of students enrolled ONLY in Business Maths, and b be the number of students enrolled in ONLY statistics.
Since the number of Business Mathematics students is 600:
a+173=600
a=600-173=427
Since the number of Statistics students is 300:
b+173=300
b=300-173=127
The total number of students is a+b+173=427+127+173=727
Answer: 727
Answer:
By the end of the day Wednesday, she had delivered 80%.
Monday alone was 32%, Tuesday alone was 28%, and Wednesday alone was 20%.
Step-by-step explanation:
20 x
----- = -----
25 100
2000 / 25 = 80% (the three days together)
Set up the same proportion to show Monday, Tuesday and Wednesday's percentages:
32%, 28% and 20% respectively. (32 + 28 + 20 = 80)
Answer:
y=3x-1 = x=1/3
Step-by-step explanation:
y=3x-1
to find the 0-intercept at x, underline y = 0
0=3x-1
move the variable to the left side and change its sign
-3x=-1
divide both sides of the equation by -3
x=1/3
