Mean of data = sum of values ÷ number of data
We have three values; 84, 87, and

Sum of values =

=

We want the value of

to give mean between 85 and 90 inclusive





Hence, the value of

is between 84 and 99 inclusive
Step-by-step explanation:
1st Step:
Volume of a cuboid : Length * Breath * Height
2nd Step :
Volume : 13.5 * 9.25 * 4.5
Which is equal to 561.9375
3rd Step:
Rounded up : 562
32^(2c)=8^(c)+7
2^10c=2^3c+21 im gonna assume 7 is in the exponent
10c=3c+21
7c=21
c=3
