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:

$P(0.79$

What are the values of a and b in the equation a[3x-8]=b-18x

3241004551 [841]

A(3x-8)=0

a=0 and x=8/3

This second line is not necessarily true. We could have a=0 OR x=8/3. They don't both have to be 0. a(3x-8)=b-18x

No solutions found

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

a*(3*x-8)-(b-18*x)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

a • (3x - 8) - (b - 18x) = 0
Step 2 :

Equation at the end of step 2 :

3ax - 8a + 18x - b = 0
Step 3 :

Solving a Single Variable Equation :

3.1 Solve 3ax-8a+18x-b = 0
