Im not sure this question is complete but the answer should be <u><em>152.4</em></u>
Answer:
The average number of daily miles traveled by these individuals was 11.72 miles per day.
Step-by-step explanation:
Given that in 2004, Pen Hadow and Simon Murray walked 680 miles to the South Pole, and the trip took 58 days, to determine the average number of miles traveled per day by these individuals the following mathematical calculation must be performed:
680/58 = X
11.72 = X
Thus, the average number of daily miles traveled by these individuals was 11.72 miles per day.

A bit complicated, so PLEASE don't ask for an explanation
The correct answer is B. Stratified sampling is used since the field is divided into subplots and a random sample is taken from each subplot.
Explanation:
Sampling refers to the process followed by researchers to select a group of individuals from a larger group; considering in most studies it is not possible to analyze all the population. In the case of stratified sampling, this involves dividing the general population into smaller groups, which are known as strata; after this, the researcher selects a specific number of individuals from each strata. This method guarantees the sample is selected randomly, and therefore the study is not biased. Stratified sampling was the method used in the example described because, in this, the general population (46-acre field) was divided into subplots that represent the strata. Also, after this, the researcher selected one random sample.
Answer:
x >5
Step-by-step explanation:
-4(3-X) > 8
Divide by -4, remembering to flip the inequality
-4/-4(3-X) < 8/-4
3-x < -2
Subtract 3 from each side
3-x-3 < -2-3
-x <-5
Divide by -1, remembering to flip the inequality
x >5
