Answer:
x=2,x=7
Step-by-step explanation:
-3x^2+27x=42
x^2-9x+14=0
x^2-2x-7x+14=0
x*(xi2)-7(x-2)=0
(x-2)*(x-7)=0
x-2=0
x-7=0
x=2
x=7

Answer:
Mean: 5
Median: 4
Mode: 4
Step-by-step explanation:
Mean:
1. To find the mean given a data set, you have to add up all the data points and then divide them by the number of data points there is.
Therefore, the mean is 5.
Median:
1. To find the median given a data set, we first have to arrange the data points in order.
2. Next, we have to find which data point is in the middle. In this case, the middle number is 4.
Therefore, the median is 4.
Mode:
1. To find the mode given a data set, you just have to find which data point is the most frequent.
- 1 data point of 2
- 3 data points of 4
- 1 data point of 6
- 1 data point of 8
Because the most frequent value is 4, the mode is 4.
