Roger's evaluation of an expression is shown.

2(1+3)^3-5^2=

step 1: 2(4)^3-5^2=

step 2: (8^3)-5^2=

step 3: 24-10=

step 4: 14

describe all of the errors roger made with his work, then correctly evaluate the expression.

my 2(1+3)^3-5^2=
4
2*4^3-5^2=
2*64-25=
128-25=103

how do i describe what he did wrong?

30 points! i am confused. what does it mean by game time? you can use a table of random numbers or a random number generator to create random samples. also, you can obtain random samples directly using wolframalpha.com. for example, typing in randomsample[{1,2,3,4,5},2] will give you a sample of size 2 from the list {1,2,3,4,5}. a sample result is {1,5}. refreshing the page will generate a new random sample of size 2. 2. create five random samples of size two from the population. record the game times for the samples and calculate the mean game time of each sample. 3. create 5 random samples of size 11 from the population. record the game times for the samples and calculate the mean game time of each sample.
