The answer is 4.8873, so you can say over 4 times as great, or almost 5 times as great for the first question.

And I think the second question could be because those over 35 years old have a more stable career, they're more developed skill-wise & worth more to their company so they're paid more, and of higher ranking in their professions, etc.

Mark ran a mean distance of 13.2 km in five days. The next day, Mark ran 20 km.

Evgen [1.6K]

Answer:

14.3 km (1 d.p.)

Step-by-step explanation:

To find the <u>mean</u>, divide the sum of all data values by the total number of data values.

If Mark ran a mean distance of 13.2 km in five days, we can use the mean distance for each of the 5 days in our calculation.

$\begin{aligned}\implies \sf mean\:distance & = \sf \dfrac{13.2+13.2+13.2+13.2+13.2+20}{6}\\ & \sf =\dfrac{86}{6}\\\\ & = \sf 14.3\:km\:\:(1\:d.p.)\end{aligned}$

Decide whether the relation defines a function.

diamong [38]

Answer:

Step-by-step explanation:

Lets first solve the relation for "y". Shown below:

$3x=9-4y\\4y=-3x+9\\y=-\frac{3}{4}x+\frac{9}{4}$

This is clearly an equation of a line in the form $y=mx+c$

It will be a negatively sloped line, when graphed.

We can use vertical line test to determine function or relation. If a vertical line passes through only 1 point in the graph, we say that it is a function.

Think of a negatively sloped line. No matter where you draw a vertical line, it will only cut the line at 1 point.

So, this is definitely an equation of a function

This exercise uses, the population growth model

timofeeve [1]

P is equal to 8700% for population x time in hours.

<h3>What is population growth model?</h3>

P is equal to 8700% for population x time in hours. 2Ae%5E%28kx%29

K's model must be solved. ln%28p%29=ln%288700%29%

2Bkx%2Aln%28e%

29\skx%

2A1=ln%28p%29-ln%288700%

29\sk=%281%

2Fx%29%

28ln%28p%29-ln%288700%29%29

Replace the point (1,10000).

k=%281%

2F1%29%

28ln%2810000%

29-ln%288700%

29%

29\sk=ln%2810000%

29-ln%288700%

29 k=0.13926, which you might only desire to three or maybe even two significant figures.

You may just enter 10000% if you want p after two hours.

And it SHOULD be the same as 8700% (2810000%2F8700%).

Just give it a shot and see, 2Ae%5E%280.139%2A2%29. More particular, the model is highlighted by p=8700%. 2Ae%5E%280.139% 2Ax%29% 29.

Determine how long to double x.

Take the logs on both sides, then find x.

To put it more simply, start with this form: 2=1%2Ae%5E%280.13926%2Ax%29
