0.8 = 1.6. this is because the model is shaded as 1.6 but 0.8 has been shown by underlining it underneath the model.
Answer: 0.0170
Step-by-step explanation:
Given : The mean amount purchased by a typical customer at Churchill’s Grocery Store is $23.50, with a standard deviation of $5.00.
i.e. 

We assume the distribution of amounts purchased follows the normal distribution.
Sample size : n=50
Let
be the sample mean.
Formula : 
Then, the probability that the sample mean is at least $25.00 will be :-

Hence, the likelihood the sample mean is at least $25.00= 0.0170

You can convert the mixed numbers to solve it easier! :)
Hello there!
I can assume you mean "Pi".
Pi is an irrational number that has an infinity decimal, also known as a terminating decimal, which means to repeat infinitely.
The summarized form of Pi is 3.14, but since you have multiple units, I can assume you want the extended form.
Here it is:
3.14159265359
I hope this helps!
