Given:
average of five numbers is 16 and four of the number are 12 , 14, 16 and 18
To find:
the remaining number
Solution:
The given numbers are 12,14,16,18
Let the another number be X
Sum of five numbers = 12+14+16+18+X
=60+X
Average of five numbers =16
Average= Sum of observations/no.of
observations
=>16=(60+X)/5
=>(60+X)/5=16
=>60+X=5×16
=>60+X=80
=>X=80-60
=>X=20
Answer:
The fifth number is 20
Answer:
a = 138
Step-by-step explanation:
Notice that from the figure, we can see that ∠MOQ and ∠PON are vertical angles, which means that by definition, they're congruent in measure.
∠MOQ = ∠MOR + ∠ROQ = 90 + 48 = 138°
So, this means that ∠PON is also equal to 138, which means a = 138.
Thus, the answer is a = 138.
