Answer: Stratified Random Sample
Step-by-step explanation:
The sample is a stratified random sample in the sense that each of the population that was sampled consisted of the necessary groups that need to be considered in their right proportion of representation which makes the sample valid for us to reasonably draw a conclusion of what to expect in the larger sample space. This sample favours every possible member of the population and helps us adequately plan for all
C = 2πr
141.3 = 2(3.14)r
141.3 = 6.28r
22.5 = r
Answer:
The new price of the books = $60.75
Step-by-step explanation:
- As the original price is: $45
As the markup is: 35% = 35/100 = 0.35
The Markup on the original price is:
0.35 × 45 = $15.75
Hence, the new price of the boots:
$45 + $15.75 = $60.75
Therefore, the new price of the books = $60.75
Answer:
The answer is C(x) = 60x + 14 and the answer to the second one is 7 days.
Step-by-step explanation:
C(x) =60x + 14
434 = 60x + 14
-14 -14
420 = 60x
/60 /60
7 = x
or
x = 7 days
