Answer:
The difference between area of pyramids is 125 sq.m.
Step-by-step explanation:
Length of base = 10m
Breadth of base = 10 m
Slant height = 15 m
Area of pyramid = Area of 5 bases
Area of pyramid = 
Area of pyramid = 400 sq.m.
Now the length of base is increased to 15
Length of base = 15m
Breadth of base = 10 m
Slant height = 15 m
Area of pyramid = Area of 5 bases
Area of pyramid =
Area of new pyramid = 525 sq.m.
Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.
Hence The difference between area of pyramids is 125 sq.m.
9 and 4. 9*4 = 36, 9 + 4 =1 1.
13 bikes
You would do 65 divided by 5 because there are 5 times as many new bikes compared to used ones
Answer:
(D), Predicting.
Step-by-step explanation:
Descriptive statistics involves various methods of collection, analysis , presentation as well as the summarization of a data set. It is involved in understanding the characteristics of the data by measuring the central tendency and measure of dispersion. Thus, it could be concluded that the prediction of the data is not done by the descriptive statistics.
Hence, the correct option is (D), Predicting.
