You play a game where you select one of three envelopes. You pay $1 to select once. One envelope has $2 inside, and the other two have nothing. What is the expected
value of this game?
Round to the nearest cent.

step-by-step explanation:

no of data

divide by no of mode

i dont know sorry

step-by-step explanation:

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.

i think the answer is d im not sure
