Answer:
( -1 , 1 )
Step-by-step explanation:
(x1,y1) = (5,9)
(x2,y2) = (-7,-7)
=(-7+5/2 , -7+9/2)
= (-1,1)
Answer:
10%
Step-by-step explanation:
In the image attached below, we can see that there are
8 tiles of letter O
2 tiles of letter V
This means that there are 10 total tiles of the letters that you want to get (O and V). Since there are a total of 100 tiles we need to divide this value by 100 to get the probability of getting one of these tiles.
10 / 100 = 0.10 or 10%
Finally, we can see that the probability of selecting a O or a V is 10%

Answer:
8) 42 in²
9) 33 cm²
10) 112 yd²
Step-by-step explanation:
8) The area is given by the formula ...
A = 1/2(b1 +b2)h
A = (1/2)(9 in +5 in)(6 in) = 42 in²
__
9) The area is half the product of the lengths of the diagonals.*
A = 1/2(d1)(d2)
A = 1/2(6 cm)(11 cm) = 33 cm²
__
10) As in the previous problem, ...
A = 1/2(14 yd)(16 yd) = 112 yd²
_____
* This formula works for any quadrilateral with perpendicular diagonals.

Answer:
11
Step-by-step explanation:
first, sort the numbers from lowest to highest.
5,5,6,7,8,9,10,*10,12*,14,15,17,18,18,18,20
the median is the number in the middle of the data
average if you need to (10+12 and divide by 2)
Answer: A. Explanation: the equation for a slope is y= mx+b, where m is the slope, and b is the y intercept. By putting -1 in the y int, and 4/5 in the slope, you get the same equation as A, so the answer is A.
