9x+3 y I’m in math hope that helps man
Answer:
54.80 MPa to 55.92 MPa
Step-by-step explanation:
Sample mean fracture strength (x) = 55.36 MPa
Sample standard deviation (s) = 3.99 MPa
Sample size (n) = 196.
The upper and lower bounds for a 95% confidence interval are given by:

The upper and lower bounds of the confidence interval are;

The 95% confidence interval for true average fracture strength is 54.80 MPa to 55.92 MPa
Step-by-step explanation:
common factor 8 and 18 is 2.
I think it’s B if not srry
Answer:
C.) n < 6
Step-by-step explanation:
Subtract 8:
n/-3 > -2
Multiply by -3. The negative multiplier requires the comparison be reversed:
n < 6
