Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean
The population standard deviation
Let be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is
The value of margin of error is
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Answer:1. (1,2) 2.(-1,0)
Step-by-step explanation:
1. 5x-4(-3x+5)=3 x=1 2. 3(2y-1)-2y=-3 y=0
y=-3x1+5 y=2 Plug them in X=2x0-1 x=-1 plug them in
The question that you have input is clearly wrong. It's not a quardratic equation. 10X2 doesn't make any sense for a quadratic equation. You should change it to 10x^2 which would make more sense
The value of x is 12 or 32
