Because it will be half2 standard deviation which will include 500-700.
2std will include from 300-700.
so it will be half of 95%.
2x - 5y = 20
At the x-intercept, y=0 .
2x = 20 ==> x = 10
At the y-intercept, x=0.
-5y = 20 ==> y = -4
Answer:
A) arithmetic sequence
g(n) = 20 + 3n
Step-by-step explanation:
Each minute, the number of pages increases by 3, which means the common difference is 3 (because it is being added, not multiplied).
If there is a common difference, it's an arithmetic sequence. (Geometric sequences have common ratios.)
If she starts at 20 pages, then you just need to multiply 3 by the number of minutes passed (n) and add it to 20 to find the page she's on.
Step-by-step explanation:
Communicative property states that, in addition, integers added in any order will still give the same answer.
So in this question,
rather than first adding 8 + (-5), we add 8 + (-8)
We know that a number + its additive Inverse (opposite sign) is equal to zero
And we know any number added to zero is equal to the number.
So we can quickly find out that the sum is -5
