Find the value of ‘x' and the length of segment ab. if b is between a and c, and ab = 3x – 3 and bc = 4x + 8, and ac = 75, then find the value of ‘x' and ab. answer

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e. g. 98.76543).

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65
