Answer:
A) Tan 60° = 1.732
B) H = 12 unit
C) Area of triangle = 41.569 unit²
Step-by-step explanation:
As shown in figure, the triangle with cone angle of 60° and base value 4 unit
A) Now, Tan 60° =
Or, Tan 60° = 1.732
B) To find value of h
since TanФ =
So, Tan 60° =
=
∴() × ( = h
∴ h = 12 unit
C) Area of this triangle = × Perpendicular × Base
= × h ×
∵ Perpendicular h = 12 unit
So, Area = × 12 ×
Hence Area of triangle = 41.569 unit²
ANSWER
Answer:
There is insufficient evidence to support the claim that the mean age is greater than 50.2 years. i.e ( μ > 50.2)
Step-by-step explanation:
Given that:
The mean age of judges in Dallas is greater than 50.2 years.
If a hypothesis test is performed, then the null and the alternative hypothesis can be computed as follows:
The null hypothesis is that the mean age of the judges in Dallas is equal to 50.2
i.e
The alternative hypothesis is that the mean age of the judges in Dallas is greater than 50.2
i.e
Decision Rule: Fail to reject the null hypothesis.
The interpretation of this decision rule implies that:
There is insufficient evidence to support the claim that the mean age is greater than 50.2 years. i.e ( μ > 50.2)
Answer:
Step-by-step explanation:
We are given the vertices of triangle ABC. We need to find the length of median AD.
Please see the attachment for figure.
D is mid point of BC because median bisect the opposite side of triangle.
Using the formula of mid point. we get coodrinate of D
D is mid point of B(1,5) and C(-3,-1)
AD is median of triangle ABC. Now we find length of median AD using distance formula of two coordinate.
A(5,1) and D(-1,2)
Thus,
