Answer:
105:175
Step-by-step explanation:
3+5 = 8
3/8 of 280 is 105.
5/8 of 280 is 175.
the ratio is 105:175
next we have to simplify it:
divide both sides by 5:
21:35 divide both sides by 7=
3:5
For which set of data is the mode 3? A 6, 2, 7, 6, 6, 6, 3, 1, 3, 9, 3 B 3, 12, 8, 5, 1, 4, 11, 13, 11, 2 C 5, 7, 3, 8, 4, 3, 5,

Answer:
Step-by-step explanation:
The mode in statistics is the number that occurs the most in a data set.
So you basically have to find the set that has the most threes.
A and C both have 3 threes. I think there might be another 3 in one of those if there has to be only one answer.
So the answer can be either A or C.
Hope this helps!
X=5, for the first one
Y= -9 for the second one
-z = 80
You cannot submit an equation with a negative letter ( -z ) so we have to cancel the negative.
To cancel negatives in the equation, we multiply both sides by -1.
-z * -1 = 80 * -1
z = -80
Answer: z = -80
