Answer:
-2/7 0r 2/-7 or the negative sign is in the middle
Step-by-step explanation:
(-3/4)(-4/7)= 3/7
3/7 x -2/3= -2/7
Answer:
see the procedure
Step-by-step explanation:
Remember that

To convert feet to inches multiply by 12

To convert minutes to seconds multiply by 60
we have

From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
Answer:
sin B = 15/17
Cos B = 8/17
Tan B = 15/8
Step-by-step explanation:
For school A: 2, 2, 3, 7, 10,10,14, 17, 22
School A : 2,2,3,7,10,10,14,17,22
Part A: (2 + 3) / 2 = 5/2 = 2.5
The Median is 10
(14 + 17) / 2 = 31/2 = 15.5
The IQR Is Q3 - Q1 = 15.5 - 2.5 = 13
For School B: <span>Nope, not symmetrical. The space between the medians should be the same number.
Hope this Helps. I can explain more if you have an comments.
