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:
8h > 154.
Step-by-step explanation:
Samantha makes $8 an hour, meaning that the total amount she makes is dependent on the amount of hours she works.
The MP3 player that she wants to purchase is $154, meaning that she will have to get at least $154 or more.
Technically, this means that your answer is:
8h ≥ 154, but because this is not a answer choice, A) 8h > 154 is your best answer, as the amount that she works (in which she is paid $8 each hour), needs to be greater then the amount she needs to purchase the MP3.
