Answer:
Step-by-step explanation:
65 ÷ b + 8 x 4 = 20
Putting value of b = 5 in the equation
65 ÷ 5 + 8 x 4 = 20
13 + 8 x 4 = 20
13 + 32 = 20
45 = 20
Bringing like terms on one side
45 - 20 = 25
Step 1
State the formula for the probability of an event
The required number of event= The students with 2 or more pets= 15+7+3+2+0 = 27
Total number of events=4+11+15+7+3+2+0=42
Step 2
Estimate the probability that a randomly selected student from this class has 2 or more pets.
Answer; Option C 27/42 or approximately 0.64
C. Multiply 16 by 11
So it would be 146. (Just in case you would like to know that too<span>…</span>)
