Step-by-step explanation:
3n+4n=-14
now add 3n and 4n
7n = -14
divide both by 7
n = -2
The answer is 5+b, so when b= 14.99, then 5+14.99=$19.99
hope this helps!
400+575+575+670+720+885+1250=5075
5075/7=725
Mean = 725
400, 575, 575, 670, 720, 885, 1250
Median = 670
725>670
C) The Mean is greater than the Median
Answer:
23
Step-by-step explanation:
7 - 5p + 3q
p = 1, q = 7
Substitute in the values of "p" and "q", and solve;
7 - 5(1) + 3(7)
7 - 5 + 21
2 + 21
