Answer:
The statements (1), (2), (4) and (6) are true.
Step-by-step explanation:
Consider the diagram below for the number line.
- The first statement is:

From the number line it is clear that the above statement is true.
- The second statement is:

From the number line it is clear that the above statement is true.
- The third statement is:

The value of √2 is 1.414. This value is less than 1.5.
So, the above statement is false.
- The fourth statement is:

From the number line it is clear that the above statement is true.
- The fifth statement is:

The value of √3 is 1.732. The difference between √2 and √3 is, 0.318.
Thus, the above statement is false.
- The sixth statement is:

The value of √3 is 1.732. The difference between √2 and √3 is, 0.318.
Implying, √3 = √2 + 0.318.
⇒√3 = √2 + 0.3
Thus, the above statement is true.

8-4×7.
Answer:
it defines an important concept of standard deviation used in probability theory and statistics. It has a major use in the formula for roots of a quadratic equation; quadratic fields and rings of quadratic integers, which are based on square roots, are important in algebra and have uses in geometry.
Answer:
4
Step-by-step explanation:
T(n) = n² + 3
T(1) = 1² + 3 = 1 + 3 = 4
Answer: speed is 540 km/h
Step-by-step explanation: Lets mark speed as v.
Because distenace is same, you can mark 6 h · 900 km/h = 10 h · v
and v = 5400 km / 10 h = 540 km/h.
Or using inverse proportions : 10 h / 6 h = v / 900 km/h .
Before multiplying you turn lastproportion around :
10 h / 6 h = 600 km/ h / v ,which gives 10 v = 6 · 900 km/h
and result is same
