Answer:
6
Step-by-step explanation:
Given :
Sample size, n = 36
Sample variance, s² = 1296
The estimated standard error can be obtained using the relation :
Standard Error, S. E = standard deviation / √n
Standard deviation, s = √1296 = 36
S.E = 36/√36
S.E = 36/6
S.E = 6
Hence, estimated standard error = 6
Answer:
x=8,−2
Step-by-step explanation:
First, you move all the terms to one side
x^2−6x+9−25=0
Then you simplify
x^2 −6x−16=0
Factor
(x−8)(x+2)=0
Which will result in x=8,−2
Answer:
3/12 or 1/4
Step-by-step explanation:
12 students in total - denominator
3 selected - numerator
simplify:
3 goes into 12 : 4 times ----> Denominator
3/3 =1 :------> Numerator
1/4 = final answer
Exponent hope this helps m8
The LCM of 3 and 4 is 12.
I hope this helps and have a good night! :D
