which of these expression is equivalent to -2(3-y)​

The mean and mean absolute deviation of this set of data will be 312. 9 and 0.19 respectively. The mean absolute deviation represents the average distance between each data value and the mean.

The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset.

Mean = 312. 9

absolute deviation = 0.19

Hence,the mean and mean absolute deviation of this set of data will be 312. 9 and 0.19 respectively. The mean absolute deviation represents. Average distance between each data value and the mean.

Answer:

Option B is correct

Step-by-step explanation:

Given

Distance from Alison's house to the mailbox  = [tex]\frac{2}{5}[/tex] miles

Distance from the mailbox to the bus stop [tex]\frac{1}{3}[/tex] miles

The total distance between Alison's house to the bus stop is

[tex]\frac{2}{5} + \frac{1}{3} \\\frac{6+5}{15} \\\frac{11}{15}[/tex]

Hence, option B is correct

Answer:

The answer is below

Step-by-step explanation:

PQRS is a rectangle. The length of rectangle PQRS = 9 cm + b cm = (9 + b)cm

The breadth of PQRS = a. Hence:

Area of PQRS = length * breadth = (9 + b)(a) = 9a + ab

but Area of PQRS = 84 cm²

9a + ab = 84          (1)

In rectangle PXYS, length = QR = a cm, breadth = YS = b cm

Hence area of PXYS = length * breadth = (a)(b) = ab

But Area of PXYS = 21 cm²

ab = 21         (2)

substitute ab = 21 in equation 1:

9a + 21 = 84

9a = 84 - 21

9a = 63

a = 7 cm

ab = 21

7b = 21

b = 3 cm

Therefore a = 7cm, b = 3 cm

Answer:

m = rise/run = 4/5.

Step-by-step explanation:

This line goes throught the "exact" grid intersections (-2, 0) and (3, 4).  As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise').  Thus, the slope of this line is m = rise/run = 4/5.
