Volume: length • height • width so
17 • 17 • 10= 2890
And since it’s a triangular prism u have to multiply it by 1/2 or 0.5 whatever form u like
2890 • 1/2= 1445 <= that’s the answer so b
Answer:
a
The 95% confidence bounds is 
b
It was not necessary to make any assumption about the shape of the travel time distribution
Step-by-step explanation:
From the question we are told that
The sample size is n = 30
The sample mean is 
The standard deviation is 
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence bounds is mathematically represented as
=>
=> 
This 95% confidence bounds show that there is 95% confidence that the true mean lies within this bound hence there is it was not necessary to make any assumption about the shape of the travel time distribution
Answer:
a+10
Step-by-step explanation:
From the table,
P(selecting a 3) = 0.15
which means that,
P(not a 3) = 1 - P(selecting a 3)
P(not a 3) = 1 - 0.15
P(not a 3) = 0.85
Answer is 0.85
