Answer:
The chart type described is the OHLC chart.
Step-by-step explanation:
An OHLC chart is a kind of bar-chart that displays open, high, low, and closing prices for each period. OHLC charts are beneficial since they demonstrates the four major data values over a period, with the closing price being reflected as the most significant by traders.
The chart type is valuable since it can represent increasing or decreasing movement. When the open and close are far-apart it represents strong movement, and when the open and close are close together it represents wavering or weak movement. The high and low displays the full price range of the period, useful in evaluating instability.
Thus, the chart type described is the OHLC chart.
The answer is 65. That's the nearest whole number.

Answer:
The solutions of the system of equations are (1 , -1) and ( , )
Step-by-step explanation:
The system of equations has a quadratic equation and a linear equation to solve it equate the two equations to find the values of x and then find the values of y
∵ y = 2x² - 8x + 5 ⇒ (1)
∵ y = x - 2 ⇒ (2)
- Equate (1) and (2)
∴ 2x² - 8x + 5 = x - 2
- Subtract x from both sides
∴ 2x² - 9x + 5 = - 2
- Add 2 to both sides
∴ 2x² - 9x + 7 = 0
Let us factorize it into two factors
∵ 2x² = (2x)(x)
∵ 7 = (7)(1)
- The last sign in the trinomial is (+) and the middle sign is (-)
then the two factors have (-) middle signs
∵ (2x)(1) + (x)(7) = 2x + 7x = 9x ⇒ nears and extreams
∴ The factors of 2x² - 9x + 7 are (x - 1)and (2x - 7)
∴ (x - 1)(2x - 7) = 0
Equate each factor by 0 to find x
∵ x - 1 = 0
- Add 1 to both sides
∴ x = 1
∵ 2x - 7 = 0
- Add 7 to both sides
∴ 2x = 7
- Divide both sides by 2
∴ x =
Now substitute the values of x in equation (2) to find the values of y
∵ x = 1
∴ y = 1 - 2 = -1
∵ x =
∴ y = - 2 =
∴ The solutions of the system of equations are (1 , -1) and ( , )
