Answer:
The z-score of a beetle with a length of 2.38 centimeters is 2.4
Step-by-step explanation:
As we know,
z = (x - µ)/σ
x is the length of the beetle species.
µ is the mean length
σ is the standard deviation
Substituting the given values in above equation, we get
z = (2.38 - 1.9)/0.2
z = 0.48/0.2
z = 2.4
Well first u need 2 divide 20/348 Because u need to fiend HOW MANY U NEED so that means you need to divide And that's how many Tiles
N equals to 2 so 4 plus 2 is 6 and that is the answer!!
Glad I could help. Have A Good day
The answer is B.




If you find a common denominator, the process becomes much easier. I hope this was helpful.
I think the answer is B. Or A.
