Answer:
17, 19, 21
Step-by-step explanation:
x = first number
x+2 = second number
x+4 = third number
4x + 3(x+2) + 2(x+4) = 167
simplify:
4x + 3x + 6 + 2x + 8 = 167
combine like terms:
9x + 14 = 167
subtract 14 from each side of the equation:
9x = 153
divide both sides by 9:
x = 17
 
        
             
        
        
        
Answer:
Not proportional. 
Step-by-step explanation:
The butterfly method multiples it like a butterfly. Ex. 5 times 3 is 15. 8 times 2 is  16. Therefore, not proportional. 
 
        
                    
             
        
        
        
Answer:
The p -value is less than 0.001.
Step-by-step explanation:
Given information:
Sample size = 25 chips
Sample mean = 985
Sample standard deviation = 10
Let as assume that sample is distributed normally.
The formula for test statistic

where, 
 is sample mean
μ is population mean.
s is sample standard deviation.
n is sample size.
The value of test statistic is



The p-value is

Therefore the p -value is less than 0.001.
 
        
             
        
        
        
The correct option is (A). The solution of the equation is x=48.125.
Given an equation 
.
A statement that uses the equal sign to show that two expressions have the same value is called an equation. The equation is represented as ax+by=c.
Firstly, we will apply the distributive property to the given equation a×(b+c)=ab+ac, we get

Now, we will simplify the right-hand side equation by taking LCM, we get

Further, we will multiply both sides with 77, we get
77×(96x/77)=77×60
96x=4620
Then, we will divide both sides with 96, we get
96x/96=4620/96
x=48.125
Hence, the solution of the given equation 
 is x=48.125.
