Answer:
3.33 but he cant buy 3 and 1/3 of a bag of chips so 4
Step-by-step explanation:
Answer:
Calculate the square root of 10 ( ) to 2 decimal places.
Find the two perfect square numbers it lies between. Solution: 32 = 9 and 42 = 16, so lies between 3 and 4.
Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)
Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.
Step-by-step explanation:
Answer:
a) 4/25, or 0.16, or 16%
b) 1/5, or 0.2, or 20%
c) The first option - the theoretical and experimental values should become closer the more trials that are performed.
Step-by-step explanation:
a) 4 of Tammy's 25 spins landed on black, so the experimental probability is 4/25, or 0.16, or 16%.
b) The spinner is split into 5 equal sections. Assuming it is fair, the chance of landing in any given section for a single spin is 1/5, or 0.2, or 20%.
c) The theoretical and experimental values should get closers the more trials you do.
For example, consider 1 coin flip vs 100. The theoretical probability of landing on a given side of a coin is 1/2, or 0.5, or 50%. With a single flip, your experimental probability will either be 0% or 100%, both off of the theoretical probability by 50%. After 100 flips however, the experimental and theoretical probabilities will be much closer to each other.
There are two other fine ways to write 11/5 .
Ten of those fifths make 2 wholes, so 11/5 can be written as<u> 2 and 1/5</u> .
Or you could do the division that the fraction shows.
Divide 11 by 5, and find the other way to write it . . . . . <u>2.2</u> .
