Answer:
New mean=71.32
Step-by-step explanation:
The expression for the total initial score is;
T=M×S
where;
T=total initial score
M=mean score
S=number in the set
replacing;
T=unknown
M=72
S=17
replacing;
T=72×17=1,224
The total initial score=1,224
Determine the total score by;
total score=total initial score+total final score
where;
total initial score=1,224
total final score=(68+63)=131
replacing;
total score=1,224+131=1,355
Determine the new mean;
New mean=total score/new number
where;
total score=1,355
new number=(17+2)=19
replacing;
new mean=1,355/19=71.32
Answer:
Alecia lives farther from school
Step-by-step explanation:
<em>Georgia</em>
we know that
The distance from the school to her home is 67/100 of a mile
<em>Alecia</em>
we know that
The distance from the school to her home is
3/10 of a mile plus 4/10 of a mile
so
Compare the distances
therefore
Alecia lives farther from school
Y=-2x+8
l hope that helps
Y = -5x + 12 since the slope of that line is -5x and in order to pass through that point the y intercept must be 12
