Answer:

the 2nd term = 2

Step-by-step explanation:

c(n)=-6(-1/3)^n-1

THen the second term is : c(2) = -6(-1/3)^2-1 = -6(-1/3)^1 = (-6)(-1/3) = 6/3 = 2

When g(x) = 3x, what is g(5)?

tamaranim1 [39]

Answer:

g(5) = 15

Explanation:

If the x in g(x) is 5 then the x beside 3 would also be 5.

g(5) = 3(5)

g(5) = 15

Hope this helps, good luck!

Explain how you can tell if a rational expression is in simplest form. Include an example with your explanation.

yan [13]

The numerator and denominators will have no common factors.

For example 4/6 is not in its simplest form because both 4 and 6 can be divided by 2. In simplest form this will be 2/3.

Someone give me the answer thanks

defon

When you plug 2 in for x, the equation equals 1. The easiest way to go about this is solving the numerator then the denominator. The denominator was equal to 3 and the numerator was equal to 3, thus making 3/3. This equals 1.

According to the 2011 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation, there were over 71 million wildif

suter [353]

Answer:

The probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is P=0.412.

Step-by-step explanation:

We know the population proportion π=0.8, according to the 2011 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation.

If we take a sample from this population, and assuming the proportion is correct, it is expected that the sample's proportion to be equal to the population's proportion.

The standard deviation of the sample is equal to:

$\sigma_s=\sqrt{\frac{\pi(1-\pi)}{N}}=\sqrt{\frac{0.8*0.2}{500}}=0.018$

With the mean and the standard deviaion of the sample, we can calculate the z-value for 0.79 and 0.81:

$z=\frac{p-\pi}{\sigma}=\frac{0.79-0.80}{0.018} =\frac{-0.01}{0.018} = -0.55\\\\z=\frac{p-\pi}{\sigma}=\frac{0.81-0.80}{0.018} =\frac{0.01}{0.018} = 0.55$

Then, the probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is:

$P(0.79$

Omar makes 8 dollars for each hour of work. write an equation to represent his total pay p after working h hours.

Natalka [10]

(8 p / h) * "x" h = p (in dollars).
_________________________________

in which: "h" = hours ;
"p" = pay (in units of dollars);
"x" = number of hours.
_________________________________
In the equation, on the left hand side, the unit symbol "h" would "cancel out" to "1" ;
and we would have:
_________________________________
8 p * x = _[total "p"]__
