Answer: 
Let total students who prefer lemonade is 2a and who prefer ice tea is a.
Students in 6th grade=39
2a+a=39
3a=39
a=39/3
a=13
students who prefer lemonate is 13
and those who prefer ice tea is 2a=26
 
        
             
        
        
        
Answer:
y = 
Step-by-step explanation:
Let the equation of the exponential function is,
y = a(b)ˣ
Since the graph of this function passes through two points  and (3, -1)
 and (3, -1)
For the point  ,
,
 ---------(1)
 ---------(1)
For second point (3, -1),
-1 = a(b)³ ---------(2)
Divide equation (2) by equation (1),
 =
 =  
 


From equation (2)
-1 = 
-1 =  
 
a = 8
Therefore, equation of the exponential function will be,
y =

Using it's concept, it is found that there is a 0.183 = 18.3% probability that the person has completed a bachelor's degree and no more.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Researching this problem on the internet, it is found that 529 + 1054 = 1583 out of 1911 + 6730 = 8641 people aged 40 or older have completed a bachelor's degree and no more, hence the probability is given by:
p = 1583/8641 = 0.183.

Answer:
Amount of frozen soup = 2500 mL
Step-by-step explanation:
We are told that tom made 5,000 mL of soup. 
We are also told he packed 2.5 Litres into his kids' lunches. 
Now, from conversions, 
1 liter = 1000 mL
Thus, 
2.5 litres = 2.5 × 1000 = 2500 mL
Now, we are told he froze the rest of the soup. 
Thus;
Amount of frozen soup = total amount of soup made - amount given to kids' lunch pack. 
Amount of frozen soup = 
5000 - 2500 = 2500 ml
