f(x) = 4x – 8?
The domain is the x values
x can be any number
the range is the y values
y can be any number
Your choices are incorrect
Answer:
(a) t = 1.6766
Step-by-step explanation:
n = 50
degree of freedom = n - 1 = 50 - 1 = 49
confidence level = 90%
The critical value corresponding to 90% confidence level and 49 degrees of freedom is obtained by interpolating between 48 and 50 degrees of freedom (df)
Let the critical value at 49 df be y
dof. critical value
48. 1.677
49. y
50. 1.676
(49 - 48)/(50 - 48) = (y - 1.677)/(1.676 - 1.677)
0.5 × -1×10^-3 = y - 1.677
y - 1.677 = -5×10^-4
y = -5×10^-4 + 1.677 = 1.6765
The closest option is (a)
21,31 porque por cada 5,5 pies hay 0,5 de diferencia de sombra

Step-by-step explanation:
a) The variable replacing y is g
The units are gallons
b) The variable replacing x is t
The units are minutes
c) We compare this with the general form of a straight line equation
g = 4t + 8
compared with y = mx + b
so we can see that b is 8 here
Putting the units , the intercept is 8 gallons
This means that at zero minute, or initially , the amount of gas in the truck’s tank is 8 gallons
In other words, the amount of gas in the tank of the truck before it started refueling in the gas station is 8 gallons
d) The slope is 4 gallons/minute
What the slope represents is the filling rate
It is simply the amount of gallons entering the gas tank per minute as the gas tank is refueling
