What is the median of this set of data 62,74,67,72,63,70,78,76

71

Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.

So let's write our data set from least to greatest.

We have 62, 63, 67, 70, 72, 74, 76, 78.

In this set however, notice that there is no 1 middle number.

In this situation, we add the two number that are in the middle and multiply the sum by 1/2. So we have 70 + 72 which is 142.

So we have 142 · 1/2 which simplifies to 71.

So the median is 71.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
