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

Simplify the following <br><br> Square root 15 / Square root 3
Elina [12.6K]

Answer:

The answer is √5 .

Step-by-step explanation:

You have to rationalize the fraction in order to get rid of surd in the denorminator by multiplying √3 to both numerator amd denorminator :

\frac{ \sqrt{15} }{ \sqrt{3} }

=  \frac{ \sqrt{15} }{ \sqrt{3} }  \times  \frac{ \sqrt{3} }{ \sqrt{3} }

=  \frac{ \sqrt{15} \times  \sqrt{3}  }{ \sqrt{3}  \times  \sqrt{3} }

=  \frac{ \sqrt{45} }{3}

=  \frac{ \sqrt{9 \times 5} }{3}

=  \frac{3 \sqrt{5} }{3}

=  \sqrt{5}

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
Mazyrski [523]

Answer:

Decrease of 63.5%.

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

y = y(0)(1+r)^{x}

In which y(0) is the initial value and r is the rate of change, as a decimal. If r is positive, it is a increase. If it is negative, it is a decrease.

In this question:

We have that:

y = 3100(0.365)^x

So

1 - r = 0.365

r = 0.365 - 1 = -0.635

So a decrease of 63.5%.
