Answer:
The data is skewed left
Less than
Median is 22
mean is 20.2
Step-by-step explanation:
<u>median: 15,16,18,19</u>,22,22,<u>22,22,23,23</u>
mean: 15+16+18+19+(22x4)+(23x2)=
31+37+88+46=
68+134=202÷10=20.2
Answer:
45 Miles
Step-by-step explanation:
Speed = Distance / Time
Distance = Speed * Time
= 7.5 * 6 = 45 Miles

Answer: x = 9</h3>
=======================================================
Explanation:
The smaller angles HGE and EGF combine to form the largest angle HGF.
This is an example of the angle addition postulate.
(angle HGE) + (angle EGF) = angle HGF
(3x+11) + (110) = 16x+4
3x+121 = 16x+4
121-4 = 16x-3x
117 = 13x
13x = 117
x = 117/13
x = 9 which is the final answer
We can stop here.
--------------------
Extra info (optional section)
Use this x value to find each angle shown below
- angle HGE = 3x+11 = 3*9+11 = 27+11 = 38 degrees
- angle HGF = 16x+4 = 16*9+4 = 144+4 = 148 degrees
Then notice how,
(angle HGE)+(angle EGF) = 38+110 = 148
which is exactly the measure of angle HGF
This confirms that the equation
(angle HGE) + (angle EGF) = angle HGF
is true for that x value of x = 9. Therefore, the answer is confirmed.
