Answer:
0.003
Step-by-step explanation:
By formula we know that:
z (x) = (x - m) / [sd / sqrt (n)]
where x is the value we want to know (60,000), m is the mean (63500), sd is the standard deviation (6100) and n is the sample size (35).
Replacing we have:
z (60000) = (60000 - 63500) / [6100 / sqrt (35)]
z = -3.39
If we look in the normal distribution table (attached), we have that the probability is 0.0003.
my answer is in the image above
The inequality would be 1.50 + .75x is less than or equal to 20. To solve this you would need to subtracts 1.50 from both sides, this would get you .75x is less than or equal to 18.5 next you would need to divide .75 on both sides ending your inequality with x is less than or equal to 24.6 repeating. To use this in the problem jasmine would be able to ride 24 miles with $20.
Answer:
total number of brown sugar cubes = 3
total number of white sugar cubes = 1
total number of sugar cubes = total no of brown sugar cubes + total no of white sugar cubes = 3 + 1 = 4
probability to select one brown sugar cube = total number of brown sugar cube / total number of sugar cube = 3/ 4
therefore the probability of selecting a brown sugar cube is 3/4 or 0.75
