Answer:

(9,-2)

Step-by-step explanation:

5 is the x coordinate, and 4 is the y coordinate. When you go right a certain amount of units, you add those units to your x coordinate. If you were to go left a certain amount of units, you'd subtract them. Since we're going right, 5 + 4 = 9. When you go up a certain amount of units, you add those units to you y coordinate. If you were to go down a certain amount of units, you'd subtract them. Since we're going up, -6 + 4 = -2. So, x = 9 and y = -2, or (9,-2)

Alan and his classmates performed a linear regression analysis on the data set shown below and found that the line of best fit t

stealth61 [152]

Answer:

C. $y=\frac{4}{5}x+7$

Step-by-step explanation:

Alan and his classmates found that the line of best fit through the data had the equation $y=-\frac{5}{4}x+18$

The slope of this line is $m=-\frac{5}{4}$

If a line would intersect this line of best fit at right angles, then the two lines are perpendicular to each other.

The slopes of perpendicular lines are negative reciprocals of each other,

Hence that line must have slope $\frac{-1}{-\frac{5}{4}} =\frac{4}{5}$

Therefore we look for a line whose slope is $\frac{4}{5}$ from the given options.

That line is the third option $y=\frac{4}{5}x+7$

$\dfrac{3}{4} + 5 - \dfrac{1}{2} = \dfrac{3}{4} + \dfrac{20}{4} - \dfrac{2}{4} = \dfrac{21}{4} = 5 \dfrac{1}{4}$

$\dfrac{2}{3} + {2}^{3} - \dfrac{1}{3} = \dfrac{2}{3} + \dfrac{24}{3} - \dfrac{1}{3} = \dfrac{25}{3} = 8 \dfrac{1}{3}$

$- 15 + 6x - 19 - 20x = - 14x - 34$

$- 7x - 2 - 9y + 10x = 3x - 9y - 2$

$14 + x = 18 \\ x = 18 - 14 \\ x = 4$

$- 5x = - 15 \\ x = - 15 \div ( - 5) \\ x = 3$

$- 2x + 8 = 18 \\ - 2x = 18 - 8 \\ - 2x = 10 \\ x = 10 \div ( - 2) \\ x = - 5$

$3x + 18 - 8x = - 17 \\ 3x - 8x = - 17 - 18 \\ - 5x = - 35 \\ x = - 35 \div ( - 5) \\ x = 7$

The circle above has an area of 144 pi cm^2. What is the area of the blue sector? Use 3.14 for pi.

sineoko [7]

Answer:

150.72 cm^2

Step-by-step explanation:

The blue area has an angle of 120 degrees, and 120/360 = 1/3, which shows that the blue area is 1/3 of the circle. In that case, the blue area is just 144pi/3. That simplifies to 48 pi.

48*3.14 = 150.72
