Answer:
39364
Step-by-step explanation:
You can simplify the equation to make 4(1+3+9...) The nth term is therefore
so u can substitute that into the equation so 4(
..). This would simplify to 4(
+
). By simplifying this, you can make it so 4(
) = 4(4+36+324+2916+6561) =39364
Answer:
1/2
Step-by-step explanation:
the probability of the die rolling an even number = the probability of the die rolling an odd number =1/2
Let us name these 2 dice as A and B
One die can roll an even and the other can roll an odd, in the following cases
A rolls even and B rolls odd. The probability of this happening =1/2×1/2
A rolls odd and B rolls even. The probability of this happening =1/2×1/2
∴ The required probability
=1/2×1/2+1/2×1/2
=1/4+1/4
=1/2
Its 20,000. If you look of make a number line use numbers 17,242 - 20,000… <3
