Answer: Choice B
Simulated probability = 0.533 (approximate)
Simulated probability is larger than theoretical probability
======================================
Explanation:
Getting heads is written shorthand as a "0".
There are 8 copies of "0" in the list out of 15, so 8/15 = 0.533 is the approximate simulated probability.
Compare this to the theoretical probability 1/2 = 0.500 (assuming this is a fair coin)
The simulated probability (0.533) is larger than its theoretical counterpart (0.500)
I give you an example 5%= 5/100
Answer:
3.75 hours
Step-by-step explanation:
Bob completes his homework in 2.5 hours.
In 1 hour, he completes 1/2.5 of his homework.
Joe completes his homework in x hours.
In 1 hour, he completes 1/x of his homework.
Together, they complete the homework in 1.5 hours.
In 1 hour, they do 1/1.5 of the homework.
1/2.5 + 1/x = 1/1.5
Convert the decimal numbers in the numerators into fractions.
1/(5/2) + 1/x = 1/(3/2)
2/5 + 1/x = 2/3
Multiply both sides by the LCD, 15x.
6x + 15 = 10x
-4x = -15
x = 3.75
Answer: 3.75 hours
Answer:
Length between the longest bolt and the shortest bolt is:
2.375 inch
If we laid one of each size bolt end to end , then the length of row of bolts is:
5.125 inch
Step-by-step explanation:
We are given that:
Martin sorted the bolts in his toolbox by size.
They measured 3/8 inch, 1/2 inch,5/8 inch, 7/8 inch, and 1 1/4 inches
longest bolt= 11/4 inches shortest bolt=3/8 inch
Difference between longest and shortest bolt= 
Now, if we lay one of each size bolt end to end then, length of row will be:
=41/8
= 5.125 inches
Justin’s fence will cost $72.
24ft = 24(12)
24(12) = 288 inches of fencing
288 (0.25) = $72
