X=first week
y=second week
z=third week
t=fourth week
18 more one 2nd week than 1st
x+18=y
x=y-18
3rd week, 4 less than 2 times as second
z=2y-4
4th week, 92
ttal=382
x+y+z+t=382
sub waht we know
x=y-18
y=y
z=2y-4
t=92
y-18+y+2y-4+92=382
conbine line terms
4y+70=382
minus 70 boht sides
4y=312
divide both sides by 4
y=78

Hope this could help you.
Oof I’m not quite sure how to do that
<span>4y-9=15
Add 9 to both sides.
4y = 24
Divide both sides by 4.
y = 6
The value of y is 6.</span>
Answer:
Step-by-step explanation:
mean = sum of data / no of data
20 + 58 + 74 + 77 + 77 + 85 + 86 + 90 + 95 + 98 / 10
760 / 10
76
to find median u should arrange the data from ascending to descending order.
since the given data is already arranged u dont need to change.
median = (N + 1)/2 (N means no of data)
=10 + 1 / 2
=11 / 2
=5.5
= 5 th term + 6 th term /2
=77 + 85 /2
=162 / 2
=81
mode means most repeating number . so in this given data 77 is repeated two times while others occured just one times . so the mode of the given data is 77.
Mode = 77
