Hi there!
First, we need to find the length of the stage. We can do this by plugging in our known values and solving for the unknown value.
WORK:
252 = 9 x l
l = 28
Next, we know that there are two lengths and two widths total. So all we need to do is to add two lengths plus to widths to find the perimeter.
WORK:
2(28) + 2(9) = P
56 + 18 = P
P = 74 feet^2
Hope this helps!! :)
In 4 days Bryn sells 24 tickets (50-26)
So in 1 day he sells 6 tickets --> B is right
The +33 in the equation means, that Eddie sold 33 tickets oon the first day
--> So C.) and D.) are right
When you replace the x in the equation with 1, you'll get the tickets, that eddie sold on the first day. --> y = 5 *(1)+33 = 38
38 tickets - 33tickets = 5 tickets ( the rise)
-->A.) is wrong, because Bryn sold two tickets more as Eddie per day
You will only get 5 million dollors so eat my D***
You have too divide 2 and 7 and 8 divided by the sum and that’s your answer
Answer:
a) 

b) From the central limit theorem we know that the distribution for the sample mean
is given by:
c)
Step-by-step explanation:
Let X the random variable the represent the scores for the test analyzed. We know that:

And we select a sample size of 64.
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
Part a
For this case the mean and standard error for the sample mean would be given by:


Part b
From the central limit theorem we know that the distribution for the sample mean
is given by:
Part c
For this case we want this probability:

And we can use the z score defined as:

And using this we got:
And using a calculator, excel or the normal standard table we have that:
