Answer:
The final cost after tax is $46.64
Step-by-step explanation:
let n be the number of times letter be found (1800), p be the success rate (0.068), and q be the failure rate (1 - 0.068 = 0.932)
mean = np = 1800 x 0.068 = 122.4
standard deviation = √(npq) = √(1800 x 0.068 x 0.932) = 10.6807414
Answer:
y=4x+5
Step-by-step explanation:
You have your mx already: (mx is slope)
y=4x
And you have your b already: (b is y-intercept)
+5
Combine equations: (Solve)
y=4x+5
Hence, the correct answer is y=4x+5
