Answer:
<em>~ Jill needs a minimum score of 90% to recieve an average of at least 92% on all her math quizzes ~</em>
Step-by-step explanation:
1. The table shows that her past weeks math quiz scores are: 92, 96, 94, 88
2. If she were to get a mean, or average, of at least 92, we could set up an equation to determine the minimum score she will recieve on her next quiz:
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒ <em>(where x is the minimum score she should recieve on her next quiz to get an average of at least 92%)</em>
3. Now let us solve this equation for x through simple algebra ⇒
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒
370 + x/5 = 92 ⇒
x/5 + 74 = 92 ⇒
x/5 = 18
x = 90

Answer:
The fraction of the students who failed to went partying =
Step-by-step explanation:
Let total number of students = 100
No. of students partied are twice the no. of students who not partied.
⇒ No. of students partied = 2 × the no. of students who are not partied
No. of students partied before the exam = 20 % of total students
⇒ No. of students partied before the exam = × 100
⇒ No. of students partied before the exam = 20
No. of students who not partied before the exam =
Thus the fraction of the students who failed to went partying =
148.5 square yards of floor covering will be needed to cover the floor.
Step-by-step explanation:
Width of floor = 4 feet 6 inches
Length of floor = 8 feet 3 inches
As we know,
1 foot = 12 inches
Therefore,
Width of floor = 4(12) + 6 = 54 inches
Length of floor = 8(12) + 3 = 99 inches
Area of floor = Length * Width
36 Inch = 1 yard
1 inch =
5346 inches =
148.5 square yards of floor covering will be needed to cover the floor.
