A radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. Set up the formula for the area of a circle. The formula is A = π r 2 it equals the area of the circle, and r equals the radius.
Solve for the radius.
Plug the area into the formula.
Divide the area by.
Take the square root.
Using the Empirical Rule, it is found that 95% of the candies have weights between 0.7 and 0.98 gram.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Researching this problem on the internet, we have that:
- The standard deviation is of 0.07.
Then 95% of the candies have weights between 0.7 and 0.98 gram, as:

Answer:
you look at the numbers and add the other numbers.
Step-by-step explanation:
You can make the equation 12x=156-x
Then from there it become 13x=156
So x=12
