Answer:
3a^4
Step-by-step explanation:
The cube root can be written as ^ 1/3
( 27 a ^12) ^ 1/3
We can write ( ab) ^c as a^c * b^c
27 ^ 1/3 a ^12 ^1/3
Rewriting 27 as 3^3
3^3 ^ 1/3 a ^12 ^1/3
We also know that a^b^c = a^(b*c)
3 ^(3* 1/3) a ^(12 *1/3)
3^1 a^4
3a^4
-7x2p= -14p
-7x-4k= 28k (negative x negative = positive
-14p+28k=....
2xp=2p
2x1=2
-14p+28k+2p+2
(-14p+2p) +28k+2
-12p+28k+2
or
28k-12p+2
Answer:
Both the mean and median and they both gives a measure of 17
Step-by-step explanation:
Given the data about the ages of 7 people :
17,20,22,12,15,12,21
Ordered data: 12, 12, 15, 17, 20, 21, 22
To find the median :
Median = 1/2 * (n+1)th term
n = number of observations = 7
Median = 1/2(7+1)th term
Median = 1/2 *8 = 4th term = 17
Mean = Σx / n = (sum of ages) / number of observations
Mean = 119 / 7 = 17
