Point A is at (3, -8) and point B is at (7, 3). What is the midpoint of line segment AB?

allochka39001 [22]

Answer:

$(5, -5/2)$

Step-by-step explanation:

The midpoint of any line segment is the average of the x- and y-values of the two endpoints.

Therefore, the midpoint of $AB$ is $((3+7)/2, (-8+3)/2)=(10/2, -5/2)=(5, -5/2)$ .

So, the answer is $\boxed{(5, -5/2)}$ and we're done!

Doug estimates that his soccer team will win 7 games this year. The team actually wins 10 games. What is the percent error of Do

baherus [9]

Answer: 30%

Step-by-step explanation:

Percent error = $\dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%$

Estimated number of games win this year = 7

Actual number of games won = 10

Now , the percent error of Doug’s estimate = $\dfrac{|7-10|}{10}\times100\%= \dfrac{3}{1}\times10\%=30\%$

Hence, the percent error of Doug’s estimate = 30%
