Answer:
y=32x-32
Step-by-step explanation:
this time no algorithm or equation was needed i saw that if the equation was y=32x there would be ordered pairs (1,32) and (2,64) so to delay it by 1  on the x side just subtract the slope from the y - intercept sorry if that doesn't make sense

Answer:

The degrees of freedom are given by:
 
 
Now we can calculate the p value with the following probability:

And for this case since the p value is lower compared to the significance level  we can reject the null hypothesis and we can conclude that the true mean for this case is different from 30.6 at the significance level of 0.05
 we can reject the null hypothesis and we can conclude that the true mean for this case is different from 30.6 at the significance level of 0.05
Step-by-step explanation:
For this case we have the following info given:
 represent the sample mean
 represent the sample mean
 represent the sample deviation
 represent the sample deviation
 represent the reference value to test.
 represent the reference value to test.
 represent the sample size selected
 represent the sample size selected
The statistic for this case is given by:

And replacing we got:

The degrees of freedom are given by:
 
 
Now we can calculate the p value with the following probability:

And for this case since the p value is lower compared to the significance level  we can reject the null hypothesis and we can conclude that the true mean for this case is different from 30.6 at the significance level of 0.05
 we can reject the null hypothesis and we can conclude that the true mean for this case is different from 30.6 at the significance level of 0.05
 
        
             
        
        
        
Answer:
72.033 ft
Step-by-step explanation:
To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.

Step 1: Switch sides

Step 2: Apply rule: 

Step 3: Multiply both sides by 

Step 4: Simplify

The bear can run 72.033 feet in 3.9 seconds
 
        
                    
             
        
        
        
Answer:
D)  x² -x - 10  =0
Step-by-step explanation:
Given that 
              
L.C.M
          
         
           
     ⇒  
 
    ⇒ 9 x + 54 = 9 x² - 36
   ⇒ 9 x² - 36 - 9x - 54 =0
 ⇒ 9 x²  - 9x - 90 =0
 ⇒ 9(x² -x - 10 ) =0
 ⇒ x² -x - 10  =0
