Answer:
Step-by-step explanation:
Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.
-We calculate the probability of a mean of 3.4 as follows:
#First determine the z-value:
#We then determine the corresponding probability on the z tables:
Hence, the probability of obtaining a sample mean this large or larger is 0.0228
it is greater than because when you multiply 8 by 3 you get 24
and you get the 3 because 3 feet make 1 yard.
Answer:
B represents 9. The opposite would be -9
Step-by-step explanation:
2 * M = X
M = to minutes
x = to how many tables washes
Answer:
<em>20%</em>
Step-by-step explanation:
<em>First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.</em>
