Answer:
0.256 * 10⁻⁵
Step-by-step explanation:
Probability of picking any answer out of 5 given options = 1/5
Total probability for 8 questions = (1/5)⁸ = 0.00000256
= 0.256 * 10⁻⁵
Im pretty sure it would be ordered: -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|
This is because
-1/2 stays as -1/2
the absolute value of |-2| is 2
the absolute value of |1/2| is 1/2
the absolute value of |-2 1/2| is 2 1/2
-2 1/2 stays as -2 1/2
and 1 1/2 stays the same as well.
If you take all these numbers (-1/2, 2, 1/2, 2 1/2, -2 1/2, and 1 1/2) and order them from least to greatest, you would get:
-2 1/2, -1/2, 1/2, 1 1/2, 2, 2 1/2
which is -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|
Im not exactly sure if it is all correct, but i hope this helps! :)
Answer:
-1199
Step-by-step explanation:
To solve this, we must use PEMDAS
1. using this, we see that we must first solve anything having to do with exponents so:
4^2 = 16
2. Then we must solve any multiplication or division (whichever comes first). So in this case:
5 x 243 = 1215
3. We are now left with 16 - 1215 so we simply subtract
16 - 1215 = -1199
