What is the ratio of 6/15 in simplest form?
6/15 = 2/5 (2 : 5)
B) 2.5 hours , because 8 mph is 1 hour and the another 8mph is 1 hour 8+8mph =16mph 1+1hr=2hr half of 8 is 4mph is .5hr so therefore 8+8+4=20mph 1+1+ 30mins= 2.5hr
Answer:
The sampling distribution of X, for a sample of size 16, will be approximately normal with mean 2 mm and standard deviation 0.01 mm.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For the population:
Mean 2 mm, standard deviation 0.04 mm
Describe the sampling distribution of X (for a sample of size 16).
Sample of size 16 means that 
By the Central Limit Theorem, approximately normal with mean 2 and standard deviation 
12 times the quantity 15 minus a number (d)....
12(15 - d) <== ur expression
Answer:
0
Step-by-step explanation:
2x-6=2x+15
2x-2x=15+6
0x/0=21/0
x=0
