$10.62? Im not sure if its correct
Answer:
I think answer is 3
Step-by-step explanation:
BD = DA
BE = EC
Now, BD/BE = DA/EC
or, x + 5/2x = 4/3
or, 3x + 15 = 8x
or, 15 = 8x - 3x
or, 15 = 5x
or, 15/5 = x
or, 3 = x
Therefore x = 3 <u>Ans</u>
Answer:
870

Array model shown below along with description (at the bottom).
Answer:
Your answer is B
Step-by-step explanation:
The lowest number is 4, therefore it cannot be C.
Now you'll have to cross out numbers on both sides and your mean will be 9 because you'll have to add 8 and 10 together and 18 divided by 2 is 9.
Next, put a line between 8 and 10, now the 8 side is the lower quartile and the 10 side is the greater quartile.
For the lower quartile, add 7 and 7 together, divide 14 by 2 and the lower quartile is 7.
For the greater quartile, add 11 and 13 together, that's 24, divide 24 by 2 and that's 12.
Lowest: 4
Mean: 9
Lower quartile: 7
Greater quartile: 12
Highest: 14
Therefore your answer is B and not A or C.
Answer:
x = -4, v = 2.5
x = -14, v = -2.5
Step-by-step explanation:
I am a bit confused with the beginning part of the question. From what I understand, you are trying to solve for x and then plug x into the top equation to find the value for V. I am sorry if that is not what you are looking for. If it is, look below!
x + 9 = 5
x = 5 -9
x = -4
v(x + 9)2 = 25
v(-4 + 9)2 = 25
v(5)2 = 25
v(10) = 25
v = 25/10
v = 2.5
x + 9 = -5
x = -5 -9
x = -14
v(x + 9)2 = 25
v(-14 + 9)2 = 25
v(-5)2 = 25
v(-10) = 25
v = 25/(-10)
v = -2.5
I hope this helped! If not, I am sorry. :(
