Answer:
He does not have enough money to buy the hat.
Step-by-step explanation:
First find out how much he spent on the ticket:
He spent $62 on the ticket, so he has $90 - $62 = $28 remaining. Now find out how much of that he spent at the concession stand:
He spent $12 at the concession stand, so he has $28 - $12 = $16 remaining. He does not have enough to buy the $18 hat.
Answer:
The standard error of the mean is 0.0783.
Step-by-step explanation:
The Central Limit Theorem helps us find the standard error of the mean:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation
.
The standard deviation of the sample is the same as the standard error of the mean. So
In this problem, we have that:
So
The standard error of the mean is 0.0783.
Answer:
D is true, E is true, F is true
Step-by-step explanation:
Hello,
n is an odd number it means that n = 2a+1 where a is integer
A
this is <u>not</u> an odd number
B
this is <u>not</u> an odd number
C
this is <u>not</u> an odd number
D
so this is an odd number
E
so this is an odd number
F
this is an odd number
hope this helps
