Slope=
m=(y1-y2)/(x1-x2)
m=(-16--15)/(19--7)
m=(-16+15)/(19+7)
m=(-1)/(26)
Slope is -1/26
Before outlier : 7.25
After outlier : 4
7.25 - 4 = 3.25
So the mean decreases by 3.25 when the outlier is removed.
Answer:
4+x>13
x>9
Step-by-step explanation:
This statement represents an inequality. To solve for the missing number first write out the inequality algebrically.
"Four more" implies that 4 is being added to the number. Another way to "a number" is to use the variable, x. So, the left side of the inequality is 4+x. Then, it says that this is "more than" 13. Thus, the greater than sign, >, should be used. This means that the final inequality is 4+x>13.
Next, you can solve the inequality by subtracting 4 from both sides. This gives x>9.
1. 5a
The multiplication sign isn’t always used in algebra, you can put the two things being multiplied together
For example 8x or 2xy
Answer:
C
Step-by-step explanation:
This is a geometric sequence with n th term
= a 
Where a is the first term and r is the common ratio
r = 
= 
= 
= 
, hence
f(n) = 16 
→ C
