Because the first thing you do is parenthesis, but there is nothing to do in the parenthesis, the first thing you do in this equation is the exponent. you do 2^3, which is 8. You are left with 4(8)-2(4)^2
4^2 is 16. you are left with 4(8) - 2(16).
4 times 8 = 32
2 times 16 = 32
32-32=0
Answer:
mean=sum of data /no of data
=66/6
=11
mean=11
for median u should arrange the data from ascending to descending order.so,
3,8,10,12,16,17
median=N+1/2(N=number of data)
=7/2
=3.5
=3 rd term + 4 th term/2
=10+12/2
=22/2
=11
median=11

Answer:
y=28
Step-by-step explanation:
1. As ABC is an isosceles triangle, that means that angle A is congruent to angle B, which means angle B measures 34˚.
2. The sum of the angles of a triangle add up to 180˚. So, make an equation:
A+B+C=180
As we already know A and B, plug them in:
34+34+C=180
Then solve:
C=112˚
3. As we know that C=4y, we can solve for y: 112/4=28
