Formula for the area of a quarter circle: A = (pi x r^2) / 4

3.14 = (3.14 x r^2) / 4

3.14r^2 = 12.56

r^2 = 4

r = 2 meters

Hope this helps! :)

deff fn [24]

Since the sum of the probabilities of all possible outcomes must be 100%, we can deduce the following:

  • Cooking in under 20 minutes: 10%
  • Cooking between 20 and 30 minutes: 85%
  • Cooking in more than 30 minutes: 5%

In fact, the probabilities of cooking in less than 20 or more than 30 sum up to 15%, which means that the remaining outcome (i.e. cooking time between 20 and 30) must complete this probability to 15, and in fact 15+85=100.

That being said, all three answers are simply a combination of these three scenarios: let C be the cooking time, for aesthetic reasons:

P(C\geq 20) = P(20 \leq C \leq 30)+P(C\geq30) = 85\%+5\%=90\%

P(20 \leq C \leq 30) = 85\%

P(C\leq 30) = P(C\leq20)+P(20 \leq C \leq 30) = 10\%+85\%=95\%

Does anyone know the answer to this? I can't understand why it isn't -7.​
faltersainse [42]

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7
