Answer:
first u need to rearrange the three sets of data in ascending order
i'll just do a set here as an example
a: 12, 14, 23, 24, 36
Mean: (12+14+23+24+36)/5 = 21.8
Median: 23
Mode: 0 (as none of the datum is repetitive)
Answer:
x = 4
y = -7
Step-by-step explanation:
y = -2x + 1
4x + y = 9
4x + y = 9
4x + (-2x + 1) = 9
4x - 2x + 1 = 9
2x + 1 = 9
2x = 9 - 1
2x = 8
x = 8/2
<u>x = 4</u>
4x + y = 9
4(4) + y = 9
16 + y = 9
y = 9 - 16
<u>y = -7</u>
Answer:

Step-by-step explanation:
From the complete question, we have:
Length D to be perpendicular to side AC
So, the area of the triangle is:

Since:
Length D is perpendicular to side AC
Then:


So:

we have

Using a graph tool
see the attached figure
The solution of the inequality is the shaded area
therefore
the answer is the option B Graph C
