Answer:
64.0% is the correct answer.
Step-by-step explanation:
As per the given scatter plot of voter turnout every year:
X axis represents the year and
Y axis represents the percentage of people who voted.
The model was predicted as per the equation:

<u>To find:</u> Prediction for the year 1900.
Putting the value of  , the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.
, the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.

So, the model predicts  for the year 1900.
 for the year 1900.
 
        
             
        
        
        
Answer:
Speed of a= 21 miles/hr
r = Speed of b= 7 miles/hr
Speed of a = 3r
Step-by-step explanation:
The cyclist are 112 miles apart
Time traveled by two = 4 hours
Speed of a = 3 * speed of b
If a cylcles 3 times More than b, then a will cover 3*distance of b 
But speed = distance/time
Time = 4hours
Total distance=112
a = 3b
3b + b = 112
4b = 112
b = 112/4
b = 28 miles
a = 3b
a = 3*28
a = 84 Miles
They bought traveled 4 hours
Speed of a = 84miles/4 hours
Speed of a= 21 miles/hr
Speed of b = 28miles/4 hours
Speed of b = 7 miles/hr
 
        
             
        
        
        
the correct question in the attached figure
(2^5)/8=2^2
we have
8----------- >2^3
(2^5)/8----------- >  (2^5)/(2^3)=2^(5-3)=2^2
therefore 
2^2=2^2-- ------> is ok
 the answer is by simplifying 8 to 2^3 to make both powers base two and subtracting the exponents
