1) Mean= Sum of total Observation/ Total no.of observation
Mean= 42/6=7
option (b) 7
2)To calculate Median first arrange the numbers in a numerically ascending order.
Since, there are even no.of total Observation median will be the mean of two middlemost terms.
3,6,7,9,9,10
Middle terms are 7 and 9
Median= 7+9/2= 8
option(c) 8
Split it up
3x^2+12x-5x-20
group
(3x^2+12x)+(-5x-20)
factor
(3x)(x+4)+(-5)(x+4)
undistribute (x+4) like ab+ac=a(b+c)
(3x-5)(x+4)
Love what tines what will give u 54 firdt of all and all up the tickest for tickest toal is adding them all up
