Answer:
B.) 6
Step-by-step explanation:
Given the data:
64 53 60 60 56 58 51 55 60
Reordered data : 51, 53, 55, 56, 58, 60, 60, 60, 64
Interquartile range = upper quartile (Q3) - Lower quartile (Q1)
Q3 = 3/4(n+1)th term
n = sample size = 9
Q3 = 3/4(9+1) = 3/4 (10) = 30/4 = 7.5 th term
Q3 = 60
Q1 = 1/4 (n + 1) th term
Q1 = 1/4(9+1) = 1/4 (10) = 10/4 = 2.5 th term
Q1 = (53 + 55) / 2
Q1 = 54
Q3 - Q1
60 - 54 = 6
Answer:
4x + y + 3 = 0
Step-by-step explanation:
4x + y = -3
y = -4x -3
Answer:
it is not a right triangle because 130 does not =121
the 2 equations are vertical angles, which mean they are equal to each other.
Set them to equal and solve for X:
x+40 = 3x
Subtract 1x from each side:
40 = 2X
Divide both sides by 2:
X = 40/2
X = 20
The answer is 200.
You have to figure out how much the profit is per necklace (10-5=5) and then take the profit of $1,000 and divide that by 5 and you get 200
