The number of blocks will be the hypotenuse of this right angle:
I NORTH
I

I
- - - - - - - - - - EAST
8²+6²= 100 & North-East =√100  = 10 blocks
        
             
        
        
        
Answer:
 
 
The 99% confidence interval would be given by (0.286;0.562)
Step-by-step explanation:
Information given:
 represent the families owned at least one DVD player
 represent the families owned at least one DVD player
 represent the total number of families
 represent the total number of families
 represent the estimated proportion of families owned at least one DVD player
 represent the estimated proportion of families owned at least one DVD player
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by  and
 and  . And the critical value would be given by:
. And the critical value would be given by:
 
The confidence interval for the mean is given by the following formula:  
 
If we replace the values obtained we got:
 
 
The 99% confidence interval would be given by (0.286;0.562)

Answer:
C. 5
Step-by-step explanation:
3x – 7 > – 1
Add 7 to each side
3x – 7+7 > – 1+7
3x> 6
Divide each side by 3
3x/3 >6/3
x >2
X must be greater than 2

Answer:
Step-by-step explanation:
Step 1:  Subtract 7 from both sides
Step 2:  Divide both sides by -3
Since you divided by a negative, you must flip the sign.
