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.

Step-by-step explanation:
Answer:
400-25π
Step-by-step explanation:
The circle and square have a radius of 10. Calculate the are of the circle, then divide by 4. Find the area of the square, then subtract the area from the area of the quarter circle you found previously.
Answer:
f(4)
Step-by-step explanation:
The output is the value of f(x) for a given value of x ( the input )
Substitute the given values of x into f(x) to determine the output, that is
f(- 8) = (- 8)³ - (- 8)² = - 512 - 64 = - 576 ≠ 48
f(- 4) = (- 4)³ - (- 4)² = - 64 - 16 = - 80 ≠ 48
f(4) = 4³ - 4² = 64 - 16 = 48
Thus f(4) gives an output of 48
