To find the mean you add up all the numbers then divide the answer by the amount of numbers there are

in this case we add 28+ 18+ 19+ 18+ 17 then divide by 5

THE MEAN IS 20!!!

Answer:

Step-by-step explanation:

To find:

The mean.

Given:

The mean is calculated by dividing all the values in a set by their left-to-right numbers.

To begin, add up all the means numbers.

Solve.

Solutions:

$\Longrightarrow: \sf{28+18+19+18+17=100}$

Five mean numbers are given.

All you have to do is divide them.

$\Longrightarrow: \sf{100\div5=\boxed{\sf{20}}$

$\Longrightarrow: \boxed{\sf{20}}$

Therefore, the mean 28, 18, 19, 18, 17 is 20, which is our answer.

I hope this helps, let me know if you have any questions.

Good luck with your assignment!

In 2013, the moose population in a park was measured to be 5,100. By 2018, the population was measured again to be 5,200. If the

Answer:

$P(t) = 5100e^{0.0039t}$

Step-by-step explanation:

The exponential model for the population in t years after 2013 is given by:

$P(t) = P(0)e^{rt}$

In which P(0) is the population in 2013 and r is the growth rate.

In 2013, the moose population in a park was measured to be 5,100

This means that $P(0) = 5100$

$P(t) = 5100e^{rt}$

By 2018, the population was measured again to be 5,200.

2018 is 2018-2013 = 5 years after 2013.

So this means that $P(5) = 5200$ .

We use this to find r.

$P(t) = 5100e^{rt}$

$5200 = 5100e^{5r}$

$e^{5r} = \frac{52}{51}$

$\ln{e^{5r}} = \ln{\frac{52}{51}}$

$5r = \ln{\frac{52}{51}}$

$r = \frac{\ln{\frac{52}{51}}}{5}$

$r = 0.0039$

So the equation for the moose population is:

$P(t) = 5100e^{0.0039t}$

Which number line correctly shows –0.8 + 0.6? A number line going from negative 1.6 to positive 1.6. An arrow goes from negative

Phoenix [80]

Answer:

Hi there, are you sure you didn't forget any parenthesis or signs? I can't find the right answer in the options, the one that would end up at -0.2 in the end I can edit my answer if you tell me some additional option or info about the expression I need to show on the number line

Step-by-step explanation:

which number line shows correctly -0.8 + 0.6?

well lets write it in words minus eight tenths plus six tenths\

so minus:

you go 0.8 units to the left from 0,

then plus:

you go 0.6 units right from -0.8, getting to -0.2

since there is no exact answer like that we can rearrange the addends 0.6-0.8, now:

we go from 0 6 tenths units to the right and get to 0.6, then we go from 0.6 eight tenths unit to the left to get to -0.2
