Answer:
Sampling variation
Step-by-step explanation: took the quiz
Answer:
The correct answer is:
![y=\frac{-x+t}{z} \\](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-x%2Bt%7D%7Bz%7D%20%5C%5C)
Step-by-step explanation:
We want to solve for the amount of money he pays each month. This is represented by y in the equation. This means we want to isolate y in the equation:
x = t - yz
We first want to subtract t from each side:
x - t = t - yz - t
x - t = -yz
Now we want to cancel the negative sign and z. We can isolate both of these at the same time; divide both sides by -z:
\frac{x-t}{-z} = \frac{-yz}{-z} \\ \\\frac{x-t}{-z}=y
We can divide the numerator by the negative sign; this gives us
\frac{-x+t}{z}=y
Answer:
n = The number of can collected after lunch
Step-by-step explanation:
Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling.
From the question, the told number rod cans collected before lunch = n
We are told that :
At the end of the day, the total number of cans collected can be represented by the expression 173 + n .
The total number of cans = Number of cans collected before lunch + Number of cans collected after Lunch
Hence:
173 + n = 173 + Number of cans collected after Lunch
Therefore, the variable n = Number of cans collected after Lunch
Answer:
plays an instrument/plays sports = 0.46
plays an instrument/does not play sports = 0.54
does not play an instrument/plays sports = 0.73
does not play an instrument/does not play sports = 0.27
Step-by-step explanation:
plays an instrument/plays sports = 6 divided by 13
plays an instrument/does not play sports = 7 divided by 13
~ you divide by 13 since the row's numbers add up to 13
does not play an instrument/plays sports = 8 divided by 11
does not play an instrument/does not play sports = 3 divided by 11
~ you divide by 11 since the row's numbers add up to 11
