Answer:
Step-by-step explanation:
Before answering we must clearly understand the difference between a statistic and a parameter.
The characteristic of a population is parameter. Example, population mean, population std deviation, population variances are called parameters.
Sample mean, sample std dev, sample variances are called statistics.
Here given that 7 math classes were surveyed and average was calcualted as 83%
Hence only sample mean = 83% and this is hence a statistic
If all 15 math classes surveyed and average taken that would have been the parameter.
Answer:
well you would need to look at how much he gets a weekend, and then worry anout the tips.
Step-by-step explanation:
He gets paid $80 each weekend, and a 15% with tips.
you would need to figure out the tips, by taking the $725 and timesing it by .15 for the percent.
which would be 108.75
you would now take 108.75 and add 80 to get what he made that weekend.
108.75+80 = 188.75 dollars

wait wait- hold on, explain??
Step-by-step explanation:
Answer:
<h2>h = 536 ft</h2>
Step-by-step explanation:
To find the height h we use tan
tan ∅ = opposite / adjacent
From the question
The adjacent is 2000 ft
The opposite is h
So we have
tan 15° = h / 2000
h = 2000 tan 15
h = 535.89 ft
h = 536 ft to the nearest foot
Hope this helps you
