Answer: Choice C) Multiplication property of inequality

The rule basically says that if you start with a < b and you multiply both sides by some positive number c, then a*c < b*c. The sign doesn't flip if you multiply both sides by a positive number.
The sign will flip if c is negative. So we'll go from a < b to a*c > b*c if c is negative.

Example 1:
1 < 5
-2 > -10 ... multiplied both sides by -2; sign flips

Example 2: 
3 < 7
9 < 21 ... multiplied both sides by 3; sign does not flip

Similar rules apply to a > b, a \le b and a \ge b

jarptica [38.1K]

Answer:

195

Step-by-step explanation:

Let wining name have, x votes

1st = x

2nd = x - 53

3rd = x - 79

4th = x - 105

x + (x - 53) + (x - 79) + (x - 105) = 963

x + x - 53 + x - 79 + x - 105 = 963

4x - 237 = 963

4x = 963 + 237

4x = 1200

x = 1200 / 4

x = 300

4th = x - 105

x - 105 = 300 - 105 = 195

MA_775_DIABLO [31]

Mean: $620, Mode: $600

Let's sort the rank stats.

First quartile: $580

Median: $610

Third quartile: $645

85th percentile: $685

OK, we're ready.  What happened to a and b?

c. $645 is the third quartile, 75th percentile.  That means 25% of the salaries are higher.

Answer: 25%

d.  $685 is the 85th percentile, 15% greater.

Answer: 15%

e.  The mean is the sum of all the salaries divided by the count.  

Mean = Sum / Count

So the sum is the count times the mean,

Sum = Count × Mean  = 100 × $620 = $62,000

Big payroll.

Answer: $62,000
