Answer:
279.62 feet
Step-by-step explanation:
We have a rectangle with 5ft x 305ft sides representing the area between your device and the base of the courthouse.
In addition to this we have an angle of 42 °
The height would come being the length of the opposite side of this triangle.
We know that:
tan (° A) = opposite / adjacent
Adjacent side is 305 ft and ° A is 42 °
Solved for opposite:
Opposite = adjacent * tan (° A)
Opposite = 305 * tan (42) = 274.62 feet
We must add 5 feet to this result and we are left with:
274.62 + 5 = 279.62
It means that the height is 279.62 feet
Answer:
Convenience sampling.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Quota sampling.
6. Convenience (opportunity) sampling.
Convenience sample can be defined as a sampling technique in which the representatives to be used are easily accessible. For example, a researcher using a social media poll such as Twitter polls.
In this scenario, Catherine Chao, Director of Marketing Research, chooses thirty-six of her closest friends to participate in the testing of a new toothpaste package. Thus, Catherine's sample is a convenience sampling.
Answer:
9
Step-by-step explanation:
since they're similair then similair sides will be proportional
CB is similair to EF
= ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
same thing if you try with the hypotenuse AB similair to DE
= ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
So, if you multiply r (DF) by 3/4 you will get the similair side AC
rx 3/4=12
r= 12÷ 3/4
r=16
