Answer:
x=12
Step-by-step explanation:
To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.
Therefore, we can set up an equation with one of the angles:
7x+6=90
7x=84
x=12
The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:
8*12-6=96-6=90
Therefore, x=12.

Answer:
a) Simple random sample
b) Random sample
c) None of them.
Step-by-step explanation:
a) This would be a simple random sample given that the dice roll is a random method to select the students and the probability of each outcome of the dice is 1/6.
b) This would be a random sample, given that the cards are shuffled, this is a random event. However, there's a condition on how to select the cards (The top ones are chosen) and therefore this can not be a simple random sample since not all cards have the same probability of being selected.
c) This is not a random sample since there is an specific condition on how to choose the students (by their age)
