Mathematics
1 answer:
MA_775_DIABLO [31]3 years ago
4 0

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

Beginning with an integer $n,$ Jake goes through the following steps: $\bullet$ 1. Take the reciprocal of the starting number. $
evablogger [386]

Answer: n= 32

Jakes started with 32

Step-by-step explanation:

Let n represent the initial integer.

Step 1: take the reciprocal.

Reciprocal of n = 1/n

Step 2: double the number obtained in step 1

= 2×1/n = 2/n

Step 3: take the reciprocal of the number obtained in step 2.

Reciprocal of 2/n = n/2

Since he ended up with 16

n/2 = 16

n = 2×16 = 32

When things are hot, the molecules and atoms move around more and faster, and when they are cold they are slower.
