Ten measurements of impact energy on specimens of a238 steel at 60 ºc are as follows: 64.1, 64.7, 64.5, 64.6, 64.5, 64.3, 64.6, 64.8, 64.2, and 64.3 j. a. use the student’s t distribution to find a 95% confidence interval for the impact energy of a238 steel at 60 ºc. b. use the student’s t distribution to find a 98% confidence interval for the impact energy of a238 steel at 60 ºc.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

191 students play sports and ninety-seven 10th graders were surveyed.
