Answer:
C.) 3.80*2.01^x
Step-by-step explanation:
Given the data :
-4 - - - -> 0.25
-3 - - - -> 0.5
-2 - - - - > 0.9
-1 - - - - - > 1.9
0 - - - - - -> 3
1 - - - - - - > 7
2 - - - - - > 18
3 - - - - -> 30
4 - - - - - > 68
The exponential regression equation is expressed in the form:
y = a * b^x
Where a = Initial value or value on the y-intercept
b = constant value
x = input value
Using the online exponential regression calculator :
y = 3.80 * 2.01^x
Answer:
The answer to your question is x = 18
Step-by-step explanation:
Use this problem using proportions
Substitution
Solve for "x"
x =
Simplification
x =
x = 18
All you have to do is add like terms,
3.2x +(-5.6x)= -2.4x
-6+4= -2
Anyway, answer is
-2.4x-2
<span> Final price=(Initial price)(100%-discount rate)
Final price=($415.80)(100%-20%)
Final price=($415.80)(80%)
Final price=($415.80)(0.8)
Answer:
Final price=$332.64 </span>
I'm assuming you mean students when you write stupids.
Give that x = students, the number of total students is equal to 9 more than 4 times x or:
4x + 9
Set that equal to 101 and solve.
The answer is 23
