Answer:
AM = 4 units
Step-by-step explanation:
In any triangle
The distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint.
The centroid divides the median in the ratio 2 : 1, that is
AM = × 12 = 4 units
Answer:
Step-by-step explanation:
so you want to start by using y=mx+b
step one: find the slope (remember m is the slope in this)
m=
m=
m=
m= -
step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.
y=mx+b
5= -4/3(0)+b
5=b
step three: rewrite y=mx+b with the values we found for m and for b
Using the t-distribution, it is found that the value of the test statistic is t = -87.3.
At the null hypothesis, it is <u>tested if the mean is of 2,463 square feet</u>, that is:
At the alternative hypothesis, it is <u>tested if the mean is smaller</u>, that is:
.
We have the <u>standard deviation for the sample</u>, hence, the <em>t-distribution</em> is used to solve this question.
The test statistic is given by:
The parameters are:
The values of the <em>parameters </em>are: .
Hence, the value of the <em>test statistic</em> is:
