The x value in the second equation (y+2) is substituted for the x in the first equation in...
Answer A.
Answer:
The correct answer is "
".
Step-by-step explanation:
According to the question,
Number of students,
= 35
A ! mid term A,
B : final A,
Didn't start,
Now,
⇒ 
then,
⇒ 
hence,
The probability will be:
⇒ 
⇒ 
B. Multiply by 100, remember it by moving the decimal over to the left 2 places
The area is 1/2 * b * h. The base is 12 and the height is 16 (the two smaller sides). The answer is 1/2 * 12 * 16, or 96.
There are nine possible combinations as follows: bb, bc, bt, cb, cc, ct, tb, tc, tt, each having a probability of 1/9. The four combinations with a cab exactly one time are: bc, cb, ct, tc. Therefore the probability that she'll use a cab exactly one time is: 4/9.
