Verified Answer :

.(-4)(-4) = 16
.litres
.9.372+ 5.72+ 4.132 = 19.179 to one decimal place = 19.2
.91 is a composite number
.5,12,1,5,7 the mode is 5 .....the mean is 6
.Miles
.203%
.foot
.-14-6= -8
.True
.97 is a Prime number
.5d= 17.1 ......so d = 17.1/5 therefore d= 3.42
.7 pounds
.12h= 120-36 =7
.-5x1x11x4= -220
.P = Parentheses first 
E = Exponents second 
MD = Multiplication and Division

Arithmetic mean - the sum of all measurements divided by the number of observations in the data set
Median - the middle value that separates the higher half from the lower half of the data set
Mode - the most frequent value in the data set
.Negative (-64)
.3x= 45.... x= 45/3 x= 15
