Answer:

Step-by-step explanation:
Given function:

As per question statement:
Initial temperature of bottle is 70
.
i.e. when time = 0 minutes, f(t) = 70 

After t = 3, f(t) = 42

Hence, the value is:

Answer:
Explanation:
The theoretical probability, P (A), of an event, A, is:
- P(A) = number of outcomes of event A / total number of possible outcomes
For 10 cranberry and 15 strawberry juices, the number of outcomes for two strawberry juices are:
- Combination of 15 strawberry juices chosen in two:

The total number of possible outcomes is:
- Combination of 25 juices chosen in two:

Thus, the probability of randomly picking two strawberry juices is:
- P (two strawberry juices) = 105/300 = 7/20
Note that you can obtain it as the product of the probabilities that the first juice is a strawberry juice and the second juice is also strawberry juice:

Yes you need to! And you need to be careful not to forgot that when doing your calculations!!
Answer:
so a circle it's 360° so if u divide 360÷1/4
3/4's obviously because the percentage is bigger.
