Can someone help me on my last problem? #10

Answers

Answer 1

Answer: ok but what did i do wrong and if you never studied the subject how did you know i was wrong

Answer 2

Answer: Based on my small expertise in this subject,

the answer should be 1/(20)^22

the logic is the same as a coin flip
1st flip: call for heads, 1/2 chance
2nd: call for heads, (multiply by self) 1/2 x 1/2= 1/4 chance
3rd: heads, 1/4 x 1/2= 1/8
and so on...

Percent error = |actual error - expected error/ expected error| * 100%

(|75-95|)/95 = 0.21

If the LCM and the HCF of two numbers are 9 and 3, respectively, what are the numbers?

Answers

Hey There!

Answer:

HCF = 9 (With the two numbers) - 18,9
LCM = 3 (with the two numbers) - 6,9

Step-by-step explanation:

HCF

If HCF is ''9''that means that ''9'' is the divisible of two numbers.

So 18 and 19 can be divided by 9 and that's the highest divisible for both factors.

And always remeber the answer is a ''Prime factor.''

LCM

If LCM is ''3'' that means ''3'' is the lowest common multiple out of two numbers.

Hope this helps!
