10. What is the distance between (8,7) and (3,-5)?
Anarel [89]

Answer:

distance between points=13 units

Step-by-step explanation:

distance between points=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

put (x_1,x_2)=(8,7) and (y_1,y_2)=(3,-5)

distance between points=\sqrt{(3-8)^2+(-5-7)^2}

distance between points=\sqrt{(-5)^2+(-12)^2}

distance between points=\sqrt{25+144}

distance between points=\sqrt{169}

distance between points=13 units answer

Inga [223]
Find the intersection point between the 2 restraint equations:
30 - 2x = 12 - \frac{1}{2} x  \\ \frac{3}{2} x = 18  \\  x = 12

Substitute back in to find y-value:
y = 30 - 2(12) = 6

P is maximized at point (12,6)
P = 9(12)+9(6) = 162

Calculate the mean absolute deviation. Round your answers to 3 significant digits
kirza4 [7]

Answer:

2.33.

Step-by-step explanation:

First we find the mean by adding the values and dividing by 11 (the number of values).

mean = 62 / 11

= 5.636

Now, we  list the absolute differences between each value and the mean:

9 - 5.636 =  3.364  the others are:

3.636, 3.636, 0.636, 2.636, 3.364, 0.364, 4.364, 1.636, 1.364, 0.636

Now the MAD is the sum of these values / 11.

MAD = 25.636/11

= 2.33..
