Answer:
Examine the mathematical expression you're working on. For example, suppose you're given 5x + 3. There are two terms here, 5x and 3. Look for the variable. In this case, x is the variable. In your case its c
Find the numerical coefficient of x. Remember to look for the number before the variable. In this case, 5 is the numerical coefficient. The term 3 is a constant and is separated from the variable by a plus sign.
Keep an eye out for negative coefficients. For example, suppose you're given the statement -y + 7 + 98. You would first identify the variable, y.
Look for the numerical coefficient of y. In this case, a "1" is implied before the variable, but it's negative in this instance. Therefore, the coefficient of y is negative 1.
Answer:
The number is 30.
Step-by-step explanation:
x/5+3=9
x/5=9-3
x/5=6
x=6*5
x=30
Answer:
AA similarity
Step-by-step explanation:
Respective angles of both triangles are 40°, 50° and 90°
AA similarity is the case:
- <em>If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar.</em>
option c is correct that if the two events are mutually exclusive than they cannot be independent.
As, we know that "mutually exclusive events are those events that do not occur at the same time".
Mutually exclusive events do not share any sample points with each other, so they cannot occur at same time. Thus, if event A and event B are mutually exclusive, they are actually inextricably dependent on each other because A's existence reduces event B's probability to zero and vice-versa.
Therefore, two events with nonzero probabilities cannot be independent and mutually exclusive because if two events are mutually exclusive, then when one of them occurs, the probability of the other must be zero.
Hence, option c is correct that if the two events are mutually exclusive than they cannot be independent.

Answer:
72 minutes
Step-by-step explanation:
It takes you 5 minutes to read 10 pages so to read 1 page it would take 10÷5= 2 minutes, therefore 36 pages will = 36 × 2 which is 72 minutes.
