Answer:
4
Step-by-step explanation:
3r = 10 + 5s
r = 10
3(10) = 10 + 5s
30 = 10 + 5r
20 = 5r
r = 4
 
        
             
        
        
        
Answer:

Step-by-step explanation:
When a quantity "A" varies DIRECTLY with another quantity "B", we can write the proportionality equation as:
A = kB
Where k is the proportionality constant (to be found)
In this problem, it is given x varies DIRECTLY with y, so we can write:
x = ky
Also, given, x = 11, y = -3, so we plug these into the equation and first find k:
x = ky
11 = k(-3)
k = -11/3
Now, we need to find x when y = 8, so we substitute and find x:

 
        
             
        
        
        
Please, write "x^3" for "the cube of x," not "x3."  "^" denotes exponentiation.
Then you have g(x) = x^3 - 5 and (I assume) h(x) = 2x - 2.
1)  evaluate g(x) at x = -2:  g(-2) = (-2)^3 - 5 = -8 - 5 = -13
2) let the input to h(x) be -13:  h(-13) = 2(-13) - 2 = -28 (answer)

<u>The population in this setting is(A) All customers who have purchased something in the last year.</u>
<u></u>
Step-by-step explanation:
As it is given in the question that 1000 customers from the list of the customers who made a purchase last year.So the list refers to the population of the people who have made a purchase last year .
The 1000 customers are the sample of the population.
