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:
y = -2/3x + 3
Step-by-step explanation:
( -3, 5)
Parallel slope = -2/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -2/3(x + 3)
y - 5 = -2/3x - 2
y = -2/3x + 3
First we need to isolate the variable so we add 15 to both sides which is
w/4=43 then we need to multiply by 4 to both sides so its 4w=172
then divide by 4 which is 43 so the answer is w=43
Answer:
2
Step-by-step explanation:
Change the mixed numbers to improper fractions
( - ) + ← the LCM of 2 and 3 is 6
= - +
= - +
= +
