Answer:
(a). $35746. (b). Higher.
Step-by-step explanation:
(a). Given that the least-squares regression equation is y = 7163x + 14242. Also, in the question above we are given that y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region, that is to say that the value of x = 30.
Therefore, y = 7163x + 14242. 
y = (7163 × 30) + 14242.
y = $35746.
(b). The condition for our x is; 28.7 percent of adults 25 years and older have at least a bachelor's degree.
Then, y = (7163 × 28.7) + 14242.
y = $34814.
Hence, we have the median income in this region = $38,163 HIGHER than $34814.
 
        
             
        
        
        
I don't understand the question, could you please re-word it and if I know it I will give u the answer
        
             
        
        
        
The sentence reads:
J equals the value of x such that x is an integer AND x is greater than -1.
Translated to English, we can say J is an integer which is zero or positive, or in other words, J is a non-negative integer.
        
             
        
        
        
Answer:
2^-4, 1/16, (1/2)^4
There is a rule with exponents, if you are dividing two exponents you subtract the first exponent from the other to simplify it, also meaning it's equivalent.
So in this case 5-9 = 2^-4
The others were found by evaluation.
 
        
             
        
        
        
Answer:
x = 45
Step-by-step explanation:
x and (90 - x) are alternate exterior angles and are congruent , then
x = 90 - x ( add x to both sides )
2x = 90 ( divide both sides by 2 )
x = 45
