Answer:
These numbers are - parameters.
Step-by-step explanation:
A study of all the students at a small college showed a mean age of 20.9 and a standard deviation of 2.9 years.
These numbers are - parameters.
These numbers are parameters as they are for all the students, and merely not a sample.
Answer:
T = a + (n-1)d
Step-by-step explanation:
The arithmetic progression formula could be used to represent the series
T = a + (n-1)d
Where a = number of miles before increase
d = intended additional number of miles each day
n= number of days
Hence on the 2nd day, number of miles to be covered by Jeff will be
T = a + (2-1)d = a + d
Answer:
x =-4
Step-by-step explanation:
4x+9 = -2x-15
Add 2x to each side
4x+2x +9 = -2x+2x-15
6x+9 = -15
Subtract 9 from each side
6x +9-9=-15-9
6x = -24
Divide each side by 6
6x/6 = -24/6
x = -4
Answer:
52 because in 1 cup equivalent to 8 ounces.. if she drinks 6 cups that is 48 ounces plus the half cups 4 ounces so 52 ounces all in all
Answer:
y=-2x+5. The slope (-2) of the equation is the same, so they are parallel.
