Answer: Rational Numbers
Step-by-step explanation: Rational numbers could be described as numbers that can be expressed as the quotient or fraction a/b of two integers, a numerator a and a non-zero denominator b. The average lap time of a swimmer will be generally given in a decimal time (i.e 55.47 seconds) these value can be expressed as the quotient or fraction a/b of two integers.
nice job, and receiving a paycheck for doing something you enjoy is great. The job requires 30 hours per
week and pays $240 per week. A check is issued every two weeks.
Alvin's first paycheck is much lower than the expected $480. The pay stub showed the following payroll
deductions: $29.76 for Social Security tax, $6.96 for Medicare tax, 62.10 for federal withholding tax, and
28.80 for state income tax. It is disappointing to receive only $352.38 and have taxes deducted. No
matter the disappointment, it is still a good opportunity to gain job experience
Case Review
1. Do these figures surprise you? What has been your experience with payroll deductions?
2. Do you think it is fair to have to pay $127.62 in taxes every two weeks? Why or why not?
3. What benefits does a worker receive from the money that went to taxes? Does Alvin receive any direct
benefits?
4. What information from the pay stub will be important when an income tax return is filed?
b. 70 <= 82 + 88 + n / 3 <= 85; 80 <= n <= 85
c. 80 <= 82 + 88 + n / 3 < 85; 70 < n < 85
d. 82 <= 80 + 85 + n / 3 <= 88; 70 <= n <= 85
Answer : option A
Jackie scored 82 and 88 on her first two quizzes
Let n be the score of third quiz
Average of 3 quiz =
average between 80 and 85, inclusive.
so average lies between 80 and 85
Question says 80 and 85 inclusive. so we use <= or >= symbol
So inequality becomes
( multiply all sides by 3)
(subtract all sides by 170)
so option A is correct
Answer:
The statement is false.
Step-by-step explanation:
For any vector 'r' we have
The magnitude is given by
As we know that the upon squaring a term the result is always positive thus the term in right side of equation i is always positive no matter weather the terms (x,y,z) are positive or negative hence we conclude that magnitude of any vectorial quantity is always positive irrespective of it's direction.
