Answer:
Kindly check explanation
Step-by-step explanation:
Total number of coin flips = 50
Number of times both coins landed head up = 20.
Hence probability of having two heads :
Probability = required outcome / Total possible outcomes
P(both heads up) = 20/50
Comparing 20/50 to 50%
We convert 20/50 to percentage :
(20/50) × 100%
0.4 × 100% = 40%
20/50 is equivalent to 40%
Hence, 40% is less than 50%
67.67 where the first one was the best in my opinion I was a bit confused when it came out of my mind that it is
(2X-3)(4-3X)
=8X-6X²-12+9X
=-6X²+17X-12
That's your answer.
-1 716/1000 can be simplified by getting and touching the fraction part. Just don't mind yet the whole number part.
The numerator 716 and the denominator 1000 are divisible by 4. So divide the numerator and denominator by 4
716 / 4 = 179
1000 / 4 = 250
So the new fraction is -1 179/250
Converting it to improper fraction, we get.
-429/250
The answer is B^5 also known as answer choice A
