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
Distribute.
2x-10-35+5x=9
Combine like terms.
7x-45=9
Add 45 to both sides.
7x=54
x= 7.7
Because you increased by the percent THEN decreased by a different percent, you subtract both percents because they are of like terms. So you do 45%-20% which equals 25% which is what’s left after dropping the total.
