Answer:
See explanation.
Step-by-step explanation:
(i) 5^3 = 125
log 5^3 = log 125
Using the rule log a^n = n log a
3 log 5 = log 125.
(ii) 3^-2 = 1/9
-2 log 3 = log 1/9
(iii) 10^-3 = 0.001
-3 log 10 = log 0.001
(iv) 81^3/4 = 27
3/4 log 81 = log 27.
Answer:
A population is defined as the data set which consists of all members of a specified group and the sample contains a part or a subset of a population.
For example : all the students of a school are population. But out of all, how many students play sports is a sample.
Hence, the answer is - A population is the complete group under study. A sample is the sub-collection of members of the population from which data are actually collected.
Answer:
it is 54
Step-by-step explanation:
i took the test and checked the answer
The percent of change would be -33.3% which would then equal a 33.3% decrease (when decimal is rounded)
what I did was turn 1/4 and 1/2 into decimals to make it easier to solve
