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:
With the mean and the standard deviaion of the sample, we can calculate the z-value for 0.79 and 0.81:
Then, the probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is:
Answer:
3/8 chocolate chips
Step-by-step explanation:
1/2 needs to have the same denominator as 7/8
2 * 4 = 8 (denominator) but what you do for the denominator has to apply for the numerator.
1 * 4 = 4 (numerator)
so now you successfully converted 1/2 to 4/8.
Now you solve, total - items you have = how much you need
7/8 - 4/8 = 3/8
Answer:
139.79 yd²
Step-by-step explanation:
area of rectangle = l·w
A = 12·9 = 108
area of semi-circle = 1/2πr²
A = 1/2·(3.14)·(9/2)²
A = 31.79
area of composite shape = 108 + 31.79
A = 139.79
i dont quite get the question but...
i guess this is how it is.
Take the mirror image of∆ABC Through the a line through the point y=3.
The new ∆ABC would have point C=(4,2)
B=(3,-6) A=(1,-3)
Now shifting the ∆ABC one unit (<em>i.e. 2 acc. to the graph as scale is 1 unit =2</em>) towards right ( or <em>adding 2 to the x coordinates of ∆ABC)</em>
We get the Coordinates of triangle ABC as A=(3,-3) B=(5,-6) C=(6,2).
This coordinate is the same coordinates of ∆A"B"C".
Hope it helps...
