Answer:
By excluding (10, 15), a better description can be given for the data set.
Step-by-step explanation:
Overall, this data seems to suggest a decreasing trend. The value (10, 15) is an outlier; if we remove it, the trend appears to be stronger. Thus if we exclude this value we can give a better description of the data set.
Answer:
0
Step-by-step explanation:
adding -7 to 7, since they are both constants (no variable) gives you 0. Adding -5x and 5x since they both have an x term gives you 0x also written as 0 (0*any number is 0). this gives you a final answer of 0
If x is rational then x + n is rational
Answer:
187 students in 7th or 8th grade
17,088 pages
Step-by-step explanation:
412 - 225 is 187.
A dozen is 12
12 x 16 x 89 = 17,088
Option C:
(11 + 8) + 1 = 11 + (8 + 1)
Solution:
Let us first define the associative property of addition.
<u>Associative property of addition:</u>
(a + b) + c = a + (b + c)
Option A: 5 + 3 = 3 + 5
This represents a commutative property of addition.
i.e. a + b = b + a.
So, it is not true.
Option B: 6 + 1 = 6 + 1
This is not under the property of associative.
It is not true.
Option C: (11 + 8) + 1 = 11 + (8 + 1)
(a + b) + c = a + (b + c)
This reflects the associative property of addition.
It is true.
Option B is the correct answer.
Hence (11 + 8) + 1 = 11 + (8 + 1) illustrates the associative property of addition.
