Answer: The distribution has an outlier
Step-by-step explanation: If you look at the graph you can clearly see it is the only one really off to the side even without doing any math.
Answer:
x = -4y/7 + 51/7
Step-by-step explanation:
First, you add all the numbers without variables and are on the same side.
7x - 4 + 4y + 8 = 55
Then you do the opposite sign (for example the opposite of addition is subtraction) of the two numbers without variables on the left side to add them to the right side(what you do on one side of the equation you must do on the other.
4x - 4 + 4 + 4y + 8 - 8 = 55 + 4 - 8
4x + 4y = 51
Then you get the x by itself by doing the same thing you did with the last step by this time with 4y. Because this has a variable, you don't add it onto the 51, but add as a different number.
4x + 4y - 4y = 51 - 4y
4x = -4y + 51
Now to isolate the x, you divide 4x by 4.
4x/4 = -4y/7 + 51/7
x = -4y/7 + 51/7
Your answer is x = -4y/7 + 51/7
Answer:
D
Step-by-step explanation:
Just multiple them and see which one fits the question.
A: 10 * 8 = 80 * 9 = 720 So it's too big.
B: 9 * 9 = 81 * 9 = 729. Also too big.
C: 9 * 10 = 90 * 9 = 810 too big.
D: 8 * 8 = 64 * 11= 704
