Answer:
y = 12+3x/6
Step-by-step explanation:
Make sure y is on one side and no terms are with it.
6y = 12+3x
y = 12+3x/6
Answer:
13.9 inches, 14.1 inches
Step-by-step explanation:
The empirical rule tells you 68% of the distribution lies within 1 standard deviation of the mean:
14.0 ± 0.1 = [13.9, 14.1]
About 68% of outside diameters lie between 13.9 inches and 14.1 inches.
Answer:
Jordans' age = 31 ; Anna's age = 19
Step-by-step explanation:
Given the 2 equations relating their ages
J + A = 50 → (1)
J = 12 + A → (2)
Substitute J = 12 + A into (1)
12 + A + A = 50
12 + 2A = 50 ( subtract 12 from both sides )
2A = 38 ( divide both sides by 2 )
A = 19
Substitute A = 19 into (2)
J = 12 + 19 = 31
Then Jordans' age = 31 ; Anna's age = 19
