We are given the expression:
(17.6^-1)^8 = 17.6 ^ -8
This means that the two terms on each side are equal. We are asked to show how this is possible.
First, use the rule of exponents. If a term raised to the power of a number x^n and is further raised to the power m: (x^n)^m, to simplify the expression, multiply n and m and this will be your end exponent = x^nm.
We can apply this rule here:
17.6^-1 ^ 8
-1 * 8 = -8
then, retain the base and replace the exponent with the product nm:
17.6 ^-8. This proves that the left term is equal to the right term. <span />
each coind has a 1/2 probability of landing on heads
3 coins would be 1/2 x 1/2 x 1/2 = 1/8 probability
To find the average, add them all up. 13 + 7 + 12 + 9 + 8 + 8 + 16 = 73
Then divide by how many numbers there are, 73 divided by 7 = 10.4285714286
10.4285714286 rounded to the nearest tenth = 10.4
Hope this helps :D
Answer:
It would be 171.00
Step-by-step explanation:
You divide 1/5 which gives you 0.2 times 4.75 and times 180 which gives you 170.00
The fourth option would be the answer.
