The daily sales at a convenience store produce a normal distribution with a mean of $1,250 and a standard deviation of $125. The probability that the sales on a given day at this store are less than $1,310 is:

0.6844 is the required probability.        

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $1,250

Standard Deviation, σ = $125

We are given that the distribution of daily sales is a bell like shaped distribution that is a normal distribution.

Formula:

We have to find

P(sales less than $1,310)

Calculation the value from standard normal z table, we have,  

0.6844 is the probability that sales on a given day at this store are less than $1,310.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
