Alma has developed a new kind of antibiotic. For the antibiotic to be sufficiently effective, it has to kill at least 90%, percent of bacteria when applied to a harmful bacteria culture. She applied her antibiotic to a petri dish full of harmful bacteria, waited for it to take effect, and then tried to estimate the percentage of dead bacteria in it. She took a random sample of 300 bacteria and found that 94%, percent of them were dead. Then she calculated the margin of error and found that the true percentage of dead bacteria is most likely to be above
90%, percent.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
