Answer:
b) 700 mg to 740 mg
Step-by-step explanation:
The mean is the sum of all the samples divided by the quantity of the samples, so a mean is a number between the maximum and the minimum sample. In this case, 720 mg must be in the interval, so letter<em> a</em> and<em> e </em>are eliminated.
The mean also represents the proportion of the samples, because the samples intend to be close to the mean. So, if 720 mg is the maximum or the minimum sample weight, it means that there are many samples close to it, and the proportion of the distribution will be small. So, letter <em>c</em> and <em>d</em> can't be the answer.
So, the largest proportion of weights is given in letter b, the interval of weights must be 700 mg to 740 mg.
Answer:
2 real solutions
Step-by-step explanation:
Since the degree of the polynomial is 2, then there are 2 solutions for the equation, but we don't know if they are both complex or both real.
Since the discriminant is
, then there are 2 real solutions.
