Rey is considering buying shares of twa stock. the stock currently sells for $50 per share. the stock changes in value at 9: 00 am each day, either increasing in value by $11 or decreasing in value by $13. the stock will increase in value with 40% probability, and decrease in value with 60% probability. the stock follows a random walk. in two days, what is the probability that the twa stock is greater than $30?
a. 64%
b. 16%
c. 35%
d. 36%
e. 24%

its 0.1 miles per minute

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

the least common denominator is 40

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.
