The mean is the average number meaning that it is all the numbers in a set added together and divided by how many number are in the set. In this case there are 4 numbers (16, 3, whatever number x is, and 5). So, to find out what x is, first you multiple 4 by the known mean which is 9.
4 x 9 = 36
Then you simply subtract 36 from all the known numbers to find x.
36 - 16 - 5 - 3 = 12
So x = 12
It might be d but i’m not sure
Answer:
14/27 feet
Step-by-step explanation:
2 1/3 feet : 4 1/2 feet
= 7/3 : 9/2
= 7/3 ÷ 9/2
= 7/3 × 2/9
= (7*2)/(3*9)
= 14/27 feet
2 1/3 feet : 4 1/2 feet = 14/27 feet
No, it is not equivalent to (x5)3. If yoh were to put 1 as a substitute for x5; 1 × 1× 1 equals 1, as represented in x5x5x5. The thing is (1)3 equals 3, as shown in (x5)3. You can substitute x5 for any number. x5x5x5 is more like it is raised to the third power than multiplied by 3.
Hope this helps!!!
