Answer:
Allocation: 4 samples should be from the mountain and 16 from along the coast.
Step-by-step explanation:
Neyman allocation is technique of sample allocation used in cases of stratified sampling.
The formula to compute the best sample size of each stratum is:
The information provided is:
Compute the range for the number of people at the mountain campsite as follows:
Then the standard deviation for the number of people at the mountain campsite will be:
Compute the range for the number of people along the coast campsite as follows:
Then the standard deviation for the number of people along the coast campsite will be:
Compute the sample size for the mountain campsite as follows:
Compute the sample size for along the coast campsite as follows:
Thus, 4 samples should be from the mountain and 16 from along the coast.
Answer:
<u>5x + 6</u>
Step-by-step explanation:
<u>To Do</u>
- Creating an algebraic expression that always results in 6 more than a multiple of 5 if the variable is an integer
<u />
<u>Solution</u>
- Let the variable be x
- Multiple of 5 ⇒ 5x
- 6 more ⇒ +6
- Expression ⇒ <u>5x + 6</u>
The tip would be $11.76 I think let me know if I'm right
Let's solve the given equation ~
Hence, we get -6 and 1 as our roots ~
So, the correct choices are : B and D
