Answer:
X + 10
Step-by-step explanation:
<h3>
Answer: 49/100</h3>
=========================================================
Explanation:
There are 7 dimes and 3 pennies, leading to 7+3 = 10 coins total.
The probability of not picking a penny is 7/10. If the first coin is put back, then the probability doesn't change for the second selection.
The probability of getting two dimes is (7/10)*(7/10) = 49/100 when the first coin is replaced.
If the first coin is not replaced, then the answer would be (7/10)*(6/9) = 42/90 = 7/15
Hence the probability that you randomly pick a black sock from the drawer is 8/18
You divide the amount the ant can carry by its weight to see how many time its own body weight it is carrying.
(1.5x10^-1g)/(3x10^-3g)=5.0x10^1
=50 times their own body weight
(3x10^-3g)x50=0.15g (which 1.5x10^-1g)
I hope this helps.
