Answer:

Step-by-step explanation:
We have been given that there are six nickels and seven dimes in your pocket. We are asked to find the probability of getting a nickel coin both times with replacement.
Let us find probability of getting a nickel in one pick.

There are 6 nickels and total coins are 6 nickels plus 7 dimes that 13 coins.

Since the coin is returned back in the pocket, so probability of choosing 2nd nickel will be
.
Since both terms are independent, therefore, probability the required probability will be product of
and
.

Therefore, our required probability would be
.
Answer: 1. -90
Step-by-step explanation:
5xy², if x=-2 and y=-3
You substitute the value into the original expression
5xy²
=5(-2)(-3)² ⇔ substitution
=(-10)(9) ⇔ multiply 5 and -2, and simplify (-3)²
=-90
Hope this helps!! :)
The answer is 29029
10000+19000+20+9=29029
