Answer:
2x²-42x-9
Step-by-step explanation:
5x²-30x-3x²-12x-9
2x²-42x-9
Empirical probability is the ratio of the number of outcomes with the actual number of trials. This means that it relies on experimental data and not on the theoretical probability.
The only options that makes use of actual data or the trials done is
A. Darren threw a football to Ted 15 times, and Ted caught it 13 times. The probability Ted will catch a throw is .
This is not possible, thus just use the Quadratic Formula or mark it as not possible.
100% - 25% = 75%
52.50 = 75% of what number?
52.50 = 0.75x
Let x = original cost
52.50 ÷ 0.75 = x
70 = x
The original cost was £70.
Hey!
So what you can do is:
1 x 1.5 = 1.5(2nd term)
1.5 x 1.5=2.25(3rd term) x 1.5=3.375(4th term) x 1.5 = 5.0625(5th term)
5.0625 x 1.5=7.59375(6th term)x1.5=<span> 11.390625
</span>11.390625 x1.5= 17.0859375(8th term)x1.5=<span> 25.62890625</span>(9th term)
The answer is D!
Hope this helps!
