Answer:
1. The relative frequency of heads is (A) reasonably close to 40%.
2. Mr. Clark's claim about the theoretical probability is likely to be (A) True.
3. This means that the theoretical probability of tails is most likely 0.6 for this coin.
( I also had this question before)
First we find how many times 4 goes into 11 as a whole. 4 goes into 11 2 times as a whole number with a remainder of 3. The whole number 2 will be 2 by itself and the remainder, 3, will be the numerator. The denominator will stay 4.
2 3/4
Answer:
(x + 2)² = 8
Step-by-step explanation:
To complete the square, write the equation standard form.
-4 + 4x + x² = 0
x² + 4x - 4 = 0
Take the middle term 4x and divide the coefficient in 2 and square it. Here it is 4/2 = 2. 2² = 4. Add 4 to both sides.
x² + 4x + 4 - 4 = 0 + 4
(x + 2)² - 4 = 4
(x + 2)² = 8
