Answer:
The correct answer is no.
Step-by-step explanation:
If a number is a factor of another number, that means that it can be equally divided into it <em>evenly</em>.
I know that 3 x 20 = 60, and 73 - 60 = 13.
Since 3 is <em>not</em> a factor of 13, it is also <em>not</em> a factor of 73.
Hope this helps! :D
Answer:
n = 6
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2n = 12 ( divide both sides by 2 )
n = 6
Answer:
15
Step-by-step explanation:
First solve for 16x20. 16*20= 320 inches. Now subtract the area that is removed, the 8x8 square. 8*8=64. 320-64=256. Our answer is 256in^2.
Answer:
(C) 32
Step-by-step explanation:
This is a problem of Permutation and Combination, not probability.
This clarification is given because most questions like this are on Probability and Statistics.
The researcher has recruited 8 participants and must divide them into two groups of 4 people each.
So there's:
GROUP A - Placebo Group
GROUP B - Experimental Group
Since the experiment is on humans - distinct objects - they will have distinct identities. Assume the 8 participants are lined up according to identities 1,2,3,4, 5,6,7,8
[2+2+2+2 +2+2+2+2] × 2 = 16×2 = 32
