Answer:
Step-by-step explanation:
Work out the Mean,
Then for every number, subtract the Mean and square the result.
Then work out the mean of those squared differences
and then take the square root of that.
Y = 9.25 just multiply 5 by .3 and add the 2 and subract that to find y
To do this you would have to do $2.00 times 1 1/4 to get the price of roast beef and $1.50 times 2 1/2.
1)To make it easier change the fractions to decimals.
(1.25)&(2.5)
2) Then do $2.00(1.25) to get
$2.50 for roast beef
3) Then do $1.50(2.50) to get
$3.75 for turkey
4)then add them together
5)3.75+2.50=$6.25
Y= -2x-8
