Answer:
- 784 ft²
- 1 cm² : 16 ft²
Step-by-step explanation:
Since we need the ratio of drawing area to floor area to figure the actual floor area, it is convenient to answer the questions in reverse order.
The ratio of drawing area to actual area is ...
... ((1 cm)/(4 ft))² = (1 cm²)/(16 ft²)
____
Then the actual floor area is ...
... (16 ft²)/(1 cm²) = actual area/(49 cm²)
Multiplying by 49 cm² gives ...
... (16 ft²)*49/1 = actual area = 784 ft²
Answer:
<em>We'll need to pull out 11 pairs of socks to be sure to get five pairs of white socks.</em>
Step-by-step explanation:
Combinations
We have 6 pairs of white socks and 6 pairs of black socks. If we wanted to pull out five pairs of white socks, there are to extreme scenarios:
The most favorable event is to take the five pairs in the first five takes. But that won't be for sure.
The worst case would be to take all the black socks first, and then take the five white socks. It would be a sure event and we must assume it as a possibility. Thus:
We'll need to pull out 11 pairs of socks to be sure to get five pairs of white socks
Answer:
Non representative
Step-by-step explanation:
A representative sample would be a subset of a population that accurately describes some characteristic from a larger group of people.
A sample of 40 patients from a local hospital is not a big enough sample to estimate the mean cholesterol level of U.S citizens (citizens from an entire country).
Therefore, this sample would be non representative.
