Given that,
A circular running track is ¼ mile long.
Elena runs on this track, completing each lap in 1/16 of an hour
To find,
Elena’s running speed.
Solution,
Formula used :
Speed = distance/time
So, Elena’s running speed is 4 mph.
Answer:
try 5
Step-by-step explanation:
Hello!
Oscar is correct, because all the steps he has taken to calculate the final price of the book are right and he has found the final price of the book.
Kim is incorrect because the steps she has taken to calculate the final price are not right, and she will not find the right final price.
YES, they have enough money to buy the book. Simply take all the steps Oscar took and calculate the final price.
28.50 × 30% = 8.55
28.50 - 8.55 = 19.95
19.95 × 10% = 1.995
19.95 + 1.995 = 21.945
This can be rounded to 21.95.
Since $21.95 is LESS than $22.00, they have enough money for the book.
Answer:
A repeating or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating (i.e. all except finitely many digits are zero). For example, the decimal representation of
1
/
3
becomes periodic just after the decimal point, repeating the single digit "3" forever, i.e. 0.333.... A more complicated example is
3227
/
555
, whose decimal becomes periodic at the second digit following the decimal point and then repeats the sequence "144" forever, i.e. 5.8144144144.... At present, there is no single universally accepted notation or phrasing for repeating decimals.
The infinitely repeated digit sequence is called the repetend or reptend. If the repetend is a zero, this decimal representation is called a terminating decimal rather than a repeating decimal, since the zeros can be omitted and the decimal terminates before these zeros.[1] Every terminating decimal representation can be written as a decimal fraction, a fraction whose divisor is a power of 10 (e.g. 1.585 =
1585
/
1000
); it may also be written as a ratio of the form
k
/
2n5m
(e.g. 1.585 =
317
/
2352
). However, every number with a terminating decimal representation also trivially has a second, alternative representation as a repeating decimal whose repetend is the digit 9. This is obtained by decreasing the final (rightmost) non-zero digit by one and appending a repetend of 9. 1.000... = 0.999... and 1.585000... = 1.584999... are two examples of this. (This type of repeating decimal can be obtained by long division if one uses a modified form of the usual division algorithm.[2])
Step-by-step explanation:
solution:
If U=W-(54.5/6) then W=U+(54.5/6).
Assuming a one-for-one transformation, the mean for W is found by adding all the W data together then dividing by 79.
That is, Wbar=(w1+w2+w3+...+w79)/79.
But w1=u1+54.5/6, w2=u2+54.5/6, etc.
So Wbar=(u1+u2+...+u79)/79+(79×54.5/6)/79=Ubar+54.5/6=6.8+54.5/6=15.8833 approx.
The variance is unaffected by the transformation since variance is simply the spread of the data which doesn’t change.
Wbar=Ubar=1.8.
