Answer:
Median is 18
Step-by-step explanation:
Firstly you have to fine y by using your mean
Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15
22+18+2y+1+10+20 over 5 =15
71+y over 5 =15
Cross multiple
71+y=75
y=4
22,18,9,10, 20
Rearrange
9,10,18,20,22
The median is 18
Pls mark answer as brainliest
Total surface area of the present=
=2*(5 in * 4.5 in)+2*(5 in * 3.5 in) + 2*(4.5 in * 3.5 in)=
=45 in² + 35 in² + 31.5 in²=111.5 in²
answer:the total surface area of the present is 111.5 in²
Answer:
does it have to be simpilfied? if not: 19/20
Step-by-step explanation:
Yea something is not right.if y=6 then you cant solve the system because you end up with x^2-4x-1
