Answer: 0.0944
Step-by-step explanation:
Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.
Number of cars tested do have faulty catalytic converters =42
Then the proportion of cars have faulty catalytic converters :
Critical value of z for 99% confidence level :
Formula for Margin of error :
Hence, the required margin of error =
Answer: m = n-1
Step-by-step explanation:
7m+2 = 7n-5
7m = 7n-5-2
7m = 7n - 7
Divide both sides by 7,
m=n-1
Given equation is
To find the x coordinate of vertex we use formula
From the given equation a= 2, b= 8 and c= -5
Plug in all the values
The x coordinate of vertex is x=-2
To find y coordinate of vertex we plug in -2 for x in the given equation
So vertex is (-2,-13)
