Answer:
The value of n is 30.25.
Step-by-step explanation:
The given expression is
....(1)
The perfect square trinomial are defined as
.....(2)
On comparing (1) and (2), we get
The given expression is perfect square trinomial if
Therefore the value of n is 30.25.
Answer: Its surface covers 1400 cm²
Explanation:
Since the length of painting = 40 cm
Breadth of painting = 35 cm
Since we know that area of rectangle is product of dimensions.
∴ Area of painting = length × breadth
= 40 cm × 35 cm
= 1400 cm²
∴ Its surface cover 1400 cm².
Considering the given data-set, we have that:
- The lowest batting average is of 0.254.
- On the histogram, 5 values would fall into the class 0.251 - 0.280.
<h3>What is an histogram?</h3>
An histogram is a graph that shows the number of times each element of x was observed, or the number of elements x in a range of values, as is used for this problem.
For the given 20 batting averages given in the table, we have that:
- Looking at all of them, the lowest value of the table is of 0.254, hence the lowest batting average is of 0.254.
- The measures in the table between 0.251 and 0.28 are: 0.277, 0.265, 0.267, 0.259, 0.254. Hence, this means that on the histogram, 5 values would fall into the class 0.251 - 0.280.

Answer:
No inequality given but in my view answer is:
x ≥ 16
Step-by-step explanation:
Given that:
Total time = 6 hours
Remaining Time = 6 - 2 hours = 4 hours (40*6 =240 mins)
Time required for 1 centerpiece = 15 mins
We have to find inequality for x:
Number of centerpieces she makes = x
In 240 mins : 240/15 centerpieces can be made
= 16 centerpieces
If she works with the same speed or more efficiently the suitable inequality would be:
x ≥ 16
I hope it will help you!
