Answer:
GK = 9cm
Step-by-step explanation:
Length of diagonal FH = 9 cm
By the property of a rectangle,
"Lengths of the diagonals of a rectangle measure the same"
FH = GK
Therefore, GK = FH = 9cm
The interquartile range (IQR) is 15.
To find the IQR, you must:
1) Find the median
2) Split the data set in two at the median.
3) Find the medians from both the groups you made in Step 2
4) Label the smaller one Quartile 1 and the larger one Quartile 3 (Hint: The median is Quartile 2)
5) Subtract: Quartile 3 - Quartile 1
Answer:
Blank 1 = 53 + 90 = 143
Blank 2 = 143 - 229 = -86
Blank 3 = 0 - 86 = 86
Answer:
A
Step-by-step explanation:
Answer:
x = one number
y = second number
Where,
x = y - 3
2y = 4x - 16
Multiply the first equation by 2 and substitute the second equation into it.
2(x=y-3) : 2x = 2y - 6
2x = (4x - 16) - 6
Combine like terms
2x = 4x - 22
2x - 2x + 22 = 4x - 2x -22 + 22
22 = 2x
22/2 = 2x/2
11 = x
