The domain of the following relation R {(3, −2), (1, 2), (−1, −4), (−1, 2)} is (1 point) a
{−1, 1, 3}

b
{−1, −1, 1, 3}

c
{−4, −2, 2, 2}

d
{−4, −2, 2}

If you can solve all of these i will give ! - 4% of 190 - 4% of 162.5 - 4% of 140 - a 4% increase from 155.1 - a 4% increase from 159.8

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
