Lúcia is using energy at a rate of 420 kilocalories (kcal) per hour (h) ice skating.
1 answer:
Answer:
7000 cal/min
Step-by-step explanation:
It is mentioned that, Lucia is using energy at a rate of 420 kilo calories per hour ice skating
We know that,
1 kilo calories = 1000 calories
Using unitary method :
420 kilo calories = 420,000 calories
Also,
1 hour = 60 minutes
In this case, Lucia is using energy per 60 minutes = 420,000 calories. So,energy used by her per minute is :
Hence, Lucia is using 7000 calories per minute.

Answer:
a. 24
b. 864
Step-by-step explanation:
a. The demand function is:
P = 60 - 2Q
When P = 12:
12 = 60 - 2Q
2Q = 60 - 12
2Q = 48
Q = 48/2 = 24
b. Consumer surplus is given as the integral of Demand function:
This implies that:
Using probability concepts, it is found that:
1. P(A) = 0.2268.
2. 100%.
3. 0%.
-------------------------
A probability is the <u>number of desired outcomes divided by the number of total outcomes.</u>
Item 1:
- 44 countries in Asia.
- Total of 23 + 12 + 47 + 44 + 54 + 14 = 194 countries.
Then:
Itens 2 and 3:
- The complement of an event is it's negation.
- Either an event happens, or it does not, that is, either the event happens, or it's complement does, thus the sum of the probabilities of an event and it's complement is of 100%.
- From the above bullet point, there is also a 0% probability that neither an event nor its complement happens.
