This is more simple than you think, it's actually quite similar to that of diameter and radius, except this is triangles instead of circles.
The "centroid" of a triangle is known as the center of mass, everything around it is perfectly evenly balanced from that point, and for triangles, it's the point of intersection for all medians. Now, when dealing with the centroid of triangles, there is a rule that always applies to every median: the distance from a vertex of the triangle to the centroid is ALWAYS twice that of the distance to the midpoint, which would be on the side opposite of the chosen vertex.
Let's call the identified side "B", the Centroid "A" and the Vertex "C"
Point B to point A is half the distance of point A to point C, as point B occurs on the opposite side of point C.
This is the same for EVERY median. You could choose any line, and any vertex, and the answer would be the same. The side, if it's opposite of the vertex, is always half the distance to the centroid as the Vertex to the centroid is.
Your answer A "Twice"

<h2>Question ???????????.???????</h2>
Answer:
There is difference in the scores of males and females
Step-by-step explanation:
Given that a professor teaches a certain section of material using a lot of examples with sports and cars to illustrate. He is concerned that this may have biased his instruction to favor male students
Since simple variances are unequal, we can do t test for comparison of two means with unequal variances
Group Group One Group Two
Mean 84.00 78.00
SD 4.00 8.00
SEM 1.26 2.53
N 10 10
The mean of Group One minus Group Two equals 6.00
95% confidence interval of this difference: From 0.06 to 11.94
t = 2.1213
df = 18
standard error of difference = 2.828
The two-tailed P value equals 0.0480
Since p <0.05 we reject null hypothesis
There is difference in the scores of males and females
Answer:
39,055
Step-by-step explanation:
so you say 6 over 100 multiplied by $36,500 over 1. then 100 into 36,500 then you get 365. then you say 6 multiplied by 365 and you get 2,555. then you say 2,555 plus 36,500 then you get 39,055
Answer:
Joe would receive $9.10 for One hour of mowing the lawn and $39.50 for Five hours of babysitting, which (if needed) adds up to $48.60
Step-by-step explanation:
It's as simple as multiplication. Since he only mowed the lawn for one hour, it would only be $9.10. Since he babysat for 5 hours, you'd simply multiply $7.90 by five, giving you the answer $39.50
