Consider the set {4, 5, 7, 8, 8, 12, 13, 13, 15, 18, 20, 22, 24, 26, 27, 37, 38}. if you were dividing the set into intervals, w

Answer:
C) 4-12
Step-by-step explanation:
<u>A) 0-7</u>
<em>Its frequency will only be 3 and there are no numbers from 0 till 3 therefore, this is not the best interval.</em>
<u>B) 4-5</u>
<em>This interval is too short. If you go on with the intervals, there will be a lot of sets. Therefore, this is not right.</em>
<u>C) 4-12</u>
<em>The set starts from 4 and so does the interval. The interval 4-12 will have a frequency of 6 and the next intervals will be 13-21, 22-30, 31-39.</em>
<em>Therefore, this is the best interval for the data.</em>
<u>D) 0-10</u>
<em>There are no numbers from 0-3 or 9-10, therefore this is not the best interval.</em>
The correct answer is option C) 4-12

<span>A+B)^2 is the largest. It is A^2+2AB+B^2, which is clearly greater than the last two options. To compare (A+B)^2 and 2(A+B), we remove one A+B so that we're just comparing A+B and 2. As A+B must be at least 3 (as both must be positive integers, and one must be greater than the other, leading to a minimum value of A=2, B=1), A+B is greater than 2, and as a result, (A+B)^2 is always the largest.</span>
Answer:
product one; it has a higher success rate
Step-by-step explanation:
to find out which has a higher rate of success we can find out their percentage of success
we can divide their success amounts by test amounts
950 / 1000 = 95/100 = 95%
150/200 = 75/100 = 75%
product 1 has a higher success rate
