Answer:
1/50 < 2.8% < 0.044 < 7/40
Step-by-step explanation:
2.8%, 7/40, 1/50, 0.044
- 2.8% = 0.028 = 28/1000
- 7/40 = 0.175 = 175/1000
- 1/50 = 0.020 = 20/1000
- 0.044 = 44/1000
<u>Ordering in ascending order</u>
- 20/1000 < 28/1000 < 44/1000 < 175/1000
<u>Same order in original numbers</u>
- 1/50 < 2.8% < 0.044 < 7/40
Answer:
3 books per month
Step-by-step explanation:
9 books ÷ 3 months = 3 books per month :)
Since
is the square of x and 6x is twice the product between x and 3, the second square must be 3 squared, i.e. 9.
So, if we think of 15 as 9+6, we have

Which is the required vertex form. This form tells us imediately that the vertex is the point (3,6).
Since the leading coefficient is 1, the parabola is facing upwards (it's U shaped), so the vertex is a minimum.
Answer:
mean = 78.4
median = 77.5
mode = 75
This is Right - skewed (positive skewness) distribution
Step-by-step explanation:
<u>Mean:-</u>
The mean (average) is found by adding all of the numbers together and dividing by the number of items and it is denoted by x⁻
mean = 
mean (x⁻ ) = 78.4
The mean of the given data = 78.4
<u>Median:</u>
The median is found by ordering the set from lowest to highest and finding the exact middle.
64 ,75, 80, 98
The middle term of the given data set = 
<u>Mode :</u>
The mode is the most common repeated number in a data set.
64 ,75, 75, 80, 98
in data the most common number = 75
<u>Conclusion</u>:-
mean = 78.4
median = 77.5
mode = 75
This is Right - skewed (positive skewness) distribution
