Answer:
k°=140°
Step-by-step explanation:
Triangles have 180° in total, use this to find the missing angle in the shaded triangle:
64°+76°+x°=180°
x°=40°
Know that lines also have 180° in total, therefore x°+k° = 180. Apply this:
40°+k°=180°
k°=140°
Answer: Y+2= 1/2(x-5)
The reason the answer contains Y+2 is that the two negatives create a positive.
Hey there!
The answer to your question is z > -4
We can solve this like it is an equation, with one exception. When you divide or multiply by a negative number, in an inequality, you have to flip the inequality sign.
-2z - 3 < 5 add 3 to both sides
-2z < 8 divide both sides by -2, and flip the inequality sign
z > -4
Good luck! Hope it helps, and have a great day!
Answer:
average of the two observations in the center of the data array
Step-by-step explanation:
When there is an odd number, we use the middle
Example
1,5,9
The median is 5
When there is an even number
1,3,5,7
The middle is between the 3 and 5 so we average the middle number
(3+5)/2 = 4
