A survey questioned 4,000 community members about how a certain parcel of land should be used (for
1 answer:
Using it's concept, it is found that the sample proportion for this population is of 0.4.
- The estimate of the <em>sample proportion for a population</em> is given by the <u>number of desired outcomes divided by the size of the sample</u>.
In this problem:
- 1,599 of those surveyed responded in favor of the park.
- The sample size is of 4,000.
Hence:
The sample proportion for this population is of 0.4.

Answer:
Approximately 66.4 Meters
Step-by-step explanation:
So we have a rectangle with a width of 18.8 meters and a diagonal with 23.7 meters. To find the perimeter, we need to find the length first. Since a rectangle has four right angles, we can use the Pythagorean Theorem, where the diagonal is the hypotenuse.
Plug in 18.8 for either <em>a </em>or <em>b. </em>Plug in the diagonal 23.7 for <em>c. </em>
<em />
Therefore, the length is 14.4 meters. Now, find the perimeter:
ANSWER
EXPLANATION
If the graph of y=cosx is transformed to y=a cos (x−c)+d by a vertical compression by a factor of 1/3 and a translation 2 units down,
then
a=1/3
and d=-2.
The 'c' is a phase shift since it is not given, it means it is zero.
Therefore the new equation is:
y=1/3cos(x-0)−2
This simplifies to:
y=1/3cosx−2
The correct option is C.
