A restaurant owner wants to see if there is a relationship between the amount of sugar in several of the food items on her menu and the number of orders of those menu items. She creates a scatter plot showing the relationship between amount of sugar in a menu item and the number of orders for that item on the menu. The correlation coefficient for the line of best fit is 0.58. a. Are they correlated?
b. Do either of the variables cause the other to change?
I did not understand this at all...

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
