Answer:
1. No, 2. 46, 3. The amount of tails flips would be more than the amount of heads flips.
Step-by-step explanation:
1 is no because .77 and .23 are not equal to .5, so her prediction was wrong. 2 is 46 because if you double both the numbers (to get a total of 200 flips), you would get 154 tails and 46 heads. 3 is more tails than heads because that is what we have observed.
6^5 = 6•6•6•6•6
x^7 = x•x•x•x•x•x•x
x^5 = x•x•x•x•x
5^6 = 5•5•5•5•5•5
6.5 liters per 100 km travelled. 30% of 5 is 1.5, so adding this to the original amount results in 6.5
Yes because 3² + 4² = 5²
to be sure
9 + 16 = 25
25 = 25
