The total number of students in 8th grade will be the sum of number of all students shown in the Venn Diagram, as the students in 8th class are the Universal set in this case.
So, total number of students in grade 8 = 34 + 14 + 44 + 15 = 107
Number of students who are taking either of these subjects as elective are shown in the colored regions and are equal to = 34 + 14 + 44 = 92
Probability of a student chosen at random taking either of these subjects as an elective = Student taking these courses as elective / Total number of students
So,
Probability of a student chosen at random taking either of these subjects as an elective = 92/107
Thus option B gives the correct answer.
X + y = 2
Substitute x + 8 into y
x + x + 8 = 2
2x + 8 =2
(Subtract 8 from both sides)
2x = -6
(Divide both sides by 2)
x = -3
Subsitute x = -3 into either equation to find y
x + y = 2
-3 + y = 2
(Add 3 to both sides)
y = 2 + 3
y = 5
Or y can be solved for using:
y = x + 8
y = -3 + 8
y = 5
85*.15=12.75
85-12.75
72.25
The sale price is $72.25
Answer:
80 feet
Step-by-step explanation:
c=d
Substitute 250 in for circumference
250=d
Divide by or 3.14
d=79.617...
So, the diameter is approximately 80 feet
Hope this helps! :)
Representing the given information mathematically, we have:
Let the number of candy pieces in the jar be
Since, it is given that:
John's guess of three times the number of candy pieces in the jar increased by is lower number than Keisha's guess of 250 less than twice the number of candy pieces.
Going to the John's guess, we get:
For the Keisha's guess, we have:
Therefore, according to the question, we get the inequality:
Anna did the mistake in comprehending the right side of the inequality correctly. Instead of comprehending she wrote: (which is incorrect).
Thus, the correct inequality is:
