Answer:
0.3114
Option d is right
Step-by-step explanation:
Let X be the time spent on a treadmill in the health club
Given that research shows that on average, patrons spend an average of 42.5 minutes on the treadmill, with a standard deviation of 5.4 minutes
Also given that X is normal
the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill.
round off to two decimals tog et
the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill is 0.31
Hence option d is right
The answer would be 10 11/20 or 10.55 in decimal form
The volume is proportional to the cube of the radius:
4^3=64
The volume will be 64 times the original value!
We must multiply 20% by 5 in order to reach 100%.
To find out the total number of pages in Oswaldo's book, we must multiply his 20% (65) by 5, therefore:
65 * 5 = 325 total pages
To find the average add all the numbers together then divide by how many numbers there are.
75+80+97+92=344 divided by 4 = 86
So her average right now is 86.
She’d have to make 96 to get an average of 88.
75+80+97+92+96=440 divided by 5=88
The answer is 96
