The answer is false because if you attach to triangles together in a way so that the figure would have 4 straight lines, you will get a rectangle. that means half of a rectangle is a triangle, so the area of both cannot be the same even if they have the same base and height.
for example the base and height of both is 3cm and 5cm.
area of the rectangle then would be,
area= base× height
=3cm×5cm=15cmsquared
then the area of the triangle would be,
area= base×height divided by 2
=3cm×5cm÷2= 7.5cm
so your answer is false
hope this helps....
Answer:
a. is effective for use in school research.
Step-by-step explanation:
Cluster sampling is the sampling whereby we pick random few sample from the population to serve as the sample population called cluster. This cluster usually have uniform characteristics among them.
The main advantage of cluster sampling is that it is effective school research because of its cheapness and doesn't require much resources during the sampling process.
The other options are not correct because Cluster sampling have High sampling error and its biased sample.
Answer:
Step-by-step explanation:
I think its the second one.
Answer:
Part 1:
P₂(0.07)=0.93245≈
Part 2:
Error=
Step-by-step explanation:
Given:
P₂(x)=
Solution:
Part 1:
P₂(x)=
We have x=0.07
Put Value of x in above Equation:
P₂(0.07)=
P₂(0.07)=0.93245≈
Part 2:
=0.93239382 (Calculated using Calculator)
Error=|-P₂(0.07)|=|0.93239382-0.93245|=0.00005618
Error=|0.93239382-0.93245|
Error=0.00005618
Error=
