Answer:
4
9/8
Step-by-step explanation:
Given the fraction a/b, the reciprocal is expressed as 1/(a/b) = b/a
For 1/4;
1/4
= 1÷1/4
= 1 * 4/1
= 4
Hence the reciprocal is 4
b) 8/9
= 1 ÷ 8/9
= 1 * 9/8
= 9/8
Hence the reciprocal of 8/9 is 9/8
That would be 7 because 7x2=14 and 14-9=5
Answer:
center; single
Step-by-step explanation:
The measures of central tendency or center measures are a number that attempts to describe or summarize the entire data set by means of a single value that represents the center of its distribution. There are different measures of central tendency, and each of them is used depending on the characteristics of the data used.
Some examples of measure of central tendency are:
* Arithmetic mean
* Mode
* Median
* Geometric mean.
Therefore, based on what has been described above, the answer to this question is the third option: center; single
Then:
A measure of __center_____ summarizes all of the values in a data set with a ____single_______ number.
In the question, they give you the formula for speed...
speed = distance / time
They also give you the distance and the time, so all we have to do is stick them into the equation...
speed = 3 2/3 Km / 1/3 hour
speed = 3 2/3 / 1/3
To divide the fractions, first we need to convert 3 2/3 into an improper fraction
3 2/3 = 11/3
now we multiply 11/3 x the reciprocal of the divisor 1/3. The reciprocal just means flip the numerator and denominator
speed = 11/3 x 3/1
speed = 33/3
speed = 11 Km/hour
Answer:
the value of x to the nearest tenth is 12 * x
