The
amount of field goals that can be achieved in a football game can only be whole
number values. For example, a field goal can only be 5 or 6 but not 5.5, 5.6 or
5.7 and etc. Therefore this is a discrete random variable.

For the given triangle, the tan of angle A equals C. 
.
Step-by-step explanation:
Step 1; In the given triangle, the opposite side has a length of 15 units, the adjacent side has a length of 36 units while the hypotenuse of the triangle measures 39 units. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.
cos A = 
.
Step 2; The opposite side's length = 15 units,
The adjacent side's length = 36 units.
cos A = 
, dividing the numerator and the denominator by 3, we get
cos A = , which is option C.
Answer:
y=3/2x+7
Step-by-step explanation:
Answer:
4) Yes
5) Yes
6) Yes
7) No
Step-by-step explanation:
4) When we look at the table in the question, we can see the pattern is comics x 3 = price.
We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.
5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.
So, this is a proportional relationship.
6) The same reasoning applies to 6, we can see they follow a pattern.
7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.
