What do you need help with?
Area of equilateral triangle = a^2/4 * √3 so side of triangle = a
but if area of equilateral triangle = area of square multiplied by √3 then area of square = a^2 / 4 so side of square = a/2
the ratio length of side triangle to length side of square = a: a/2 that means the side of triangle is doubled the side of square
answer
a) 2:1
When the population mean and standard deviation are known, you use the standard normal distribution
<h3>How to determine the distribution?</h3>
There are several probability distributions; these include
- Normal distribution
- Poisson distribution
- Chi square distribution
- Binomial distribution
- Etc
Of all these distribution, only the standard normal distribution can be used when the population mean and standard deviation are known,
Note that it is also referred to as the z-distribution
