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
They are functions if the x’s don’t repeat. A, C, D are functions
Okay so I don't know what you're trying to find out here, but if you're trying to find out how many words he has left after writing those two months, all you have to do is add. 35, 295 + 19, 240 and should get 54, 535. Then you subtract 95,234 - 54,535 and get 40,699.. So Zachary has 40,699 words left to write
To transform a mixed number to an improper fraction, we must multiply the denominator by the large number, and add the numerator.
So for :
But we also put this over the denominator in the mixed number, so we get: .
Then we do the same for :
Then we must find a common denominator. Let's use 21 (multiply 3 and 7):
Now that we have a common denominator, we can subtract across:
Since cannot be reduced any further, we are going to leave this as our answer.
So the answer is .
