Answer:
x = 2.6  
Step-by-step explanation:
To find x, you need to find how many times you need to multiply 25 to get 65. Using reverse operations will make this easier. 65 / 25 = 2.6. We can check this by multiplying 25 by 2.6, and we get 65.
 
        
             
        
        
        
Answer: The answer is 300 gallons.
Step-by-step explanation: Riemann sum is a method of calculating the total  area under a curve on a graph, which is also known as Integral.
To calculate that area, we divide it into a number of rectangles with one point touching the curve. The curve has a closed interval [a,b] that can be subdivided into n subintervals, each having a width of Δ =
 = 
If a function is defined on the closed interval [a,b] and  is any point in [
 is any point in [ ,
, ], then a Riemann Sum is defined as ∑f(
], then a Riemann Sum is defined as ∑f( )Δ
)Δ .
.
For this question:
Δ =
 =  = 1.4
 = 1.4
Now, we have to find s(t) for each valor on the interval:
s(t) = 0.29 - t +25
 - t +25
s(0) = 25
s(1) = 24.29
s(2) = 24.16
s(3) = 24.61
s(4) = 25.64
s(5) = 27.25
s(6) = 29.44
s(7) = 32.21
Now, using the formula:
∑f( )Δ
)Δ = 1.4(25+24.29+24.16+24.61+25.64+29.44+32.21)
 = 1.4(25+24.29+24.16+24.61+25.64+29.44+32.21)
∑f( )Δ
)Δ = 1.4(212.6)
 = 1.4(212.6)
∑f( )Δ
)Δ ≅ 300
 ≅ 300
With Riemann Sum, it is estimated the total country's per capita sales of bottled water is 300 gallons.
 
        
             
        
        
        
Answer:
39/40
Step-by-step explanation:
Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.
However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)
