A number is chosen at random from 1 to 50. Find the probability of selecting an odd number

1/2

Step-by-step explanation:

There are 25 odd numbers between 1 and 50.There are total of 50 numbers. Probability is 25/50.

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
