Answer:
The point slope form of this equation would be y - 0 = -2(x + 1)
Step-by-step explanation:
In order to find this, we start by identifying that the x-intercept at -1 is the point (-1, 0). Now we can use that full point and the slope and plug them into the base form of point-slope form.
y - y1 = m(x - x1)
y - 0 = -2(x - -1)
y - 0 = -2(x + 1)
Answer:
B.No. It describes the midrange, not the median.
Step-by-step explanation:
Further,
The range is the difference between the least and largest value of data. It measures skewness using all data points.
Mean is calculated as the ratio of the sum of all the observations to the total number of observations.
Median is the middle value of the data after arranging them in ascending order.
Answer:
Call the numbers a, b, c, d. What does it say if their mean is 15? That would be that added together then divided by 4 you get 15. So the number before you divided by 4, which is the sum, was 60. If you know some algebra, the equation (a+b+c+d)/4=15 gives the sum of 60 when you multiply both sides
