4 and 5
Answer: 8/343
Step-by-Step:
If two similar solids have a scale factor of a:b then,
The ratio of their surface areas (2D) is- a^2:b^2
The ratio of their volume (3D) is- a^3:b^3
First you want to square root the scale factor numbers to find the original value. Then you cube the original numbers to find the answer.
Answer: 925 pages
Step-by-step explanation:
From the question, we are told that with a full ink cartridge, a printer can print 2,500 pages but that the printer cartridge is now 37% full.
The best estimate of the number of pages the printer can still print will be calculated as:
= 37% × 2500
= 0.37 × 2500
= 925 pages
Answer:
5.0
Step-by-step explanation:
0.16÷0.03220=4.9689
=5.0
The sample was 10 numbers.
4 of the numbers are less than 301.
So 4 out of 10 would be defective.
4/10 = 0.4 x 100 = 40%
He would expect 40% to be defective.
