Answer:
What is the question
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
m+x=500
0.3m+0.1(x)=500*0.25
x=500-m
0.3m+(0.1(500-m))=0.25*500
0.3m-0.1m+50=125
0.2m+50=125
0.2m=75
m=75*5
m=375

Answer:
C
Step-by-step explanation:
Mean is the average. To find mean, add all the numbers in a data set, then divide by the number of values.
Example: 1,2,3,4,5
Mean: 1+2+3+4+5= 15
Number of values: 5
15/5 = 3
Mean is 3
