The answer to your problem is 54.
Answer:
Correct option is (B) descriptive statistical method
Step-by-step explanation:
Descriptive statistics branch in statistics deals with the representation of the data using distinct brief coefficients. These coefficients are used as either the representative of the sample or the population.
The descriptive statistics branch is divided into two sub branches:
- Measure of central tendency
- Measure of dispersion.
The three measures of central tendency are:
- Mean (or Average)
- Median
- Mode.
The measures of dispersion are:
- Variance
- Standard deviation
- Range
- Kurtosis
- Skewness
The education researcher computes the average number of hours student study at various local colleges.
The average of a data is the mean value which is the measure of central tendency.
Thus, the researcher is using descriptive statistical method to summarize the data.
Step-by-step explanation:
3 3/5-2/3
change into improper fraction
18/5-2/3
take LCM of denominator
18*3-2*5/15
54-10/15
44/15
In a place value relationships. The relationship between 2
the same digit place next to each other is the value of the number to left is
10 times bigger than to the value to the left and from the decimal point to the
right is 10 times smaller of value than the digit in their right.<span>
</span>
Let say for example:<span>
1111
1 thousands, 1 hundreds, 1 tens, and 1 ones.
Let’s start from 1 = 1 x 10 = 10
That would be 10 X 10 = 100
then 100 X 10 = 1000
Notice that their value increase base on its place value if
we multiply the given number by 10. </span>
Another one is
912.98 in where 9 is hundreds, 1 is tens, 2 is ones and after
the decimal points, in where 9 is tenths and 8 is hundredths.<span>
<span>Notice each place value next to each other. Each value is ten
times in difference.</span></span>
