Answer:
(1.21875, 23.765625)
Step-by-step explanation:
-b/2a gives you the x value of the maximum point, with b=39 and a = -16
-39/2(-16) = 1.21875 = x
Plug that value back in and get the y value
would be the y value.
I included all the digits because you didn't tell me how many significant figures.
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
subtract 3 from 23 and u will get 20 then divide 2 by 2 and 2 by 20
x= 10
