Answer:
0.7 seconds
Step-by-step explanation:
You have to subtract both lap times, but before doing so you need to know what 2/5 is in decimal form. To do so, you must do 2 divided by 5, getting 0.4 seconds as it's a fraction converting to decimal. This means Fam swam 29.4 seconds, which instead of 2/5, you have 0.4 as your converted answer, so you would substitute it after 29. Then, you would do 29.40 subtracted by 28.7 and get 0.7 seconds as your answer to find out the difference of their swim times.
the expression that is equivalent is 7^6*7^1
Answer:
Step-by-step explanation:
The range of a function y = f(x) is the set of values y takes for all values of x within the domain of f. The graph of any quadratic function, of the form f(x) = a x2 + b x + c, which can be written in vertex form as follows. f(x) = a(x - h)2 + k where h = - b / 2a and k = f(h) is either a parabola opening up, when a > 0, or a parabola opening down, when a < 0
There are three 1/3's in an hour ( 1/3 + 1/3 + 1/3 = 3/3 = 1)
You can cook 3 pounds every hour.
At most you can cook 4 hours. Multiply 4 by 3:
4 x 3 = 12 pounds.
Answer:
C. A sample of size n from a population of size N is obtained through simple random sampling if every possible sample of size n has an equally likely chance of occurring. The sample is then called a simple random sample.
Step-by-step explanation:
Simple Random Sampling is the sampling where samples are chosen randomly, where each unit has an equal chance of being selected in a sample.
Option A is incorrect as the size of the sample and size of the population is not the same generally if it does happen then there will be no difference between sample and population.
Option B is incorrect as Simple Random Sampling is not a chance it is a way that samples can be taken.
Option D is incorrect as when samples are taken using a convenient sample then it is called Convenient Sample, not Simple Random Sample.
Thus, only option C is correct.
