For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is
Answer: We are required to find the value of z corresponding to probability 0.8340.
i.e., 
We can find the value of z using the standard normal table.
Using the standard normal table, we have:

Therefore, for the value of z = 0.97, cumulative standardized normal distribution is 0.8340
Attached here standard normal table for your reference.
Answer:
8r+7t
Step-by-step explanation:
Tripled
original volume 3*6*10=180
when one is tripled 3(3) * 6*10 = 3*3*6*10=180*3
it doesnt matter which is tripled
