Answer:
.
Step-by-step explanation:
We have been given an image of a triangle. We are asked to find the mid-segment of .
We know that mid-segment of triangle joins midpoints of two sides of triangle and parallel to the third side of the triangle.
We can see that point M is midpoint of segment BC and point L is midpoint of segment AB. We can also see that segment LM is parallel to side AC, therefore, segment LM is the mid-segment of our given triangle.
The <em><u>correct answer</u></em> is:
c)75.4 to 94.6
Explanation:
The formula for a confidence interval is:
,
where μ is the mean, z is the z-score associated with the level of confidence we want, σ is the standard deviation, and n is the sample size.
Our mean is 85, our standard deviation is 12, our sample size is 6, and since we want 95% confidence, our z-score is 1.96:
