What is the solution to the equation? a + 5 and two-thirds = 9

a + 5 and two-thirds = 9. a + 5 and two-thirds + 5 and two-thirds = 9 minus 5 and two-thirds. A = 3 and one-third.

a + 5 and two-thirds = 9. a + 5 and two-thirds + 5 and two-thirds = 9 + 5 and two-thirds. A = 14 and two-thirds.

a + 5 and two-thirds minus 5 and two-thirds = 9 + 5 and two-thirds. A = 14 and two-thirds.

a + 5 and two-thirds minus 5 and two-thirds = 9 minus 5 and two-thirds. A = 3 and one-third.

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
