The correct answer is B) -0.3
Z-scores are found using the formula
z = (X-μ)/σ
For this problem, we have
z = (24-24.5)/1.7 = -0.5/1.7 = -0.3
Answer:
15x 12y=489
Step-by-step explanation:
In the problem it says that x is the number of adult shirts which 15 and y is the number for a youth shirt. So it would be 15x 12y. Hope this helped! :D
We should use lb to convert weight to kg
let unknown lb be = X
14 lb = 1 stone
X lb = 9 stone
Cross multiply : X × 1 = 9 × 14
X = 126 / 1 = 126 lb
9 stone = 126 lb
let unknown value of kg be = Y
2.2 lb = 1kg
126 lb = Y kg
Cross multiply : 2.2 × Y = 126 × 1
Y = 126 / 2.2 = 57.3 kg
So 9 stone = 126 lb = 57.3 kg
