This venn diagram represents the science subjects studied by students what is the probability that a student, chosen at random, studies physics and chemistry or both ?

Step-by-step explanation:

Looking at the Venn diagram :

The total number of students surveyed is 7+5+8+6+2+4+3+6 = 41

The number of students that studies physics is = 14

The number of students that studies chemistry is =  21

Probability  = number of favorable outcomes / total number of outcomes

Therefore  the probability that a student chosen at random studies physics and chemistry or both is  35/41 = 0.85

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

you'll have to attache the image of the bar graph in order for us to answer : )
