Answer:
Q1 value is 3.0625 inches
Step-by-step explanation:
Q1 is the 25th percentile, that is
P(z<z*)=0.25 where z* is the z-score of the 25th percentile.
Corresponding z* is -0.675.
z* can also be calculated using the equation
z= where
- X is the 25th percentile(Q1) value
- M is the mean rainfall in January in the city (3.4 inches)
- s is the standard deviation (0.5 inches)
Solving the equation for X, we have X=-0.675×0.5+3.4 =3.0625 inches
Answer: X = 11/5
Step-by-step explanation: Put it in standard form first!!
simplify -2 + 4x = 9 - x
regroup items 4x - 2 = 9 - x
Add two on both sides 4x = 9 - x + 2
simplify 9 - x + 2 to 11 - x
4x = 11 - x
Add x to both sides 4x + x = 11
Simplify 4x + x to 5x
5x = 11
divide both sides by 5
x = 11/5
