The hard drive was 24.32% full when the transfer began. 
4.4 x 32 = 140.8
384 - 140.8 = 243.2
243.2 divided by 1000 = 0.2432 
Move the decimal 2 places to the right to create a percentage and you now have your answer of 24.32%
        
             
        
        
        
Answer:
Step-by-step explanation:
Given the sample data
Pre-test... 12 14 11 12 13 
Post-Test 15 17 11 13 12 
The mean of pre-test
x = ΣX / n
x = (12+14+11+12+13) / 5
x = 12.4
The standard deviation of pre-test
S.D = √Σ(X-x)² / n
S.D = √[(12-12.4)²+(14-12.4)²+(11-12.4)²+(12-12.4)²+(13-12.4)² / 5]
S.D = √(5.2 / 5)
S.D = 1.02.
The mean of post-test
x' = ΣX / n
x' = (15+17+11+13+12) / 5
x' = 13.6
The standard deviation of post-test
S.D' = √Σ(X-x)² / n
S.D' = √[(15-13.6)²+(17-13.6)²+(11-13.6)²+(13-13.6)²+(12-13.6)² / 5]
S.D = √(23.2 / 5)
S.D = 2.15
Test value
t = (sample difference − hypothesized difference) / standard error of the difference
t = [(x-x') - (μ- μ')] / (S.D / n — S.D'/n)
t = (12.4-13.6) - (μ-μ')/ (1.02/5 - 2.15/5)
-1.5 = -1.2 - (μ-μ') / -0.226
-1.5 × -0.226 = -1.2 -(μ-μ')
0.339 = -1.2 - (μ-μ')
(μ-μ') = -1.2 -0.339
μ-μ' = -1.539
Then, μ ≠ μ'
We can calculate our P-value using table. 
This is a two-sided test, so the P-value is the combined area in both scores.
The p-value is 0.172
The p value > 0.1
 
 
        
             
        
        
        
Answer:  x<-10
Step-by-step explanation:
the < in the math equation means that the number to the right is greater than the number to the left.   x can not be -10 it has to be lower (smaller).
 
        
                    
             
        
        
        
Answer:5 percent
Step-by-step explanation: subtract new amount minus old amount then divide then make the decimal you get into and change to a percent
