The weight of strawberries follows a normal distribution with a mean weight of 12 grams and a standard deviation of 2.5 grams. I
1 answer:
This is a problem of Standard Normal distribution.
We have mean= 12 grams
Standard Deviation = 2.5 grams
First we convert 8.5 to z score. 8.5 converted to z score for given mean and standard deviation will be:
So, from standard normal table we need to find the probability of z score to be less than -1.4. The probability comes out to be 0.0808
Thus, the <span>probability that the strawberry weighs less than 8.5 grams is 0.0808</span>

<h3>Resolution - Explanation</h3>
Square root is a real number x multiplied by itself - which results in a perfect value, where it is possible to calculate the real proof (which is the square root).
Given the expression, , first step: we will calculate the root of the numerator and denominator of this fraction:
<u />
<u />
Step two: rearranging the expression and canceling the common factors x, we will have,:
Therefore, the final answer to this multiplication will be 1/9.
