Find the mean and median of the data set 3,5,6,2,10,9,7,5,11,6,4,2,5,4
Tanya [424]
Answer:
mean: 5.6 ; median: 5
Step-by-step explanation:
first order them:
2, 2, 3, 4, 4, 5, 5, 5, 6, 6, 7, 9, 10, 11
now we can see that the median is 5 since it's in the middle
and the mean is adding all and dividing by how many numbers we have (AKA 14) so 2+2+3+4+4+5+5+5+6+6+7+9+10+11 = 79 and now we divide 79 by 14 which is:
5.64285714
The greatest common factor (GCF) of 21 and 84 is 21.
The GCF is the largest number by which both numbers can be divided. Between 21 and 84, it is 21 because 21/21=1 and 84/21=4.
Answer:
if given f(-x)=x-7, then f(h(x))=-2x-10
or if given f(x)=x-7, then f(h(x))=2x-4
Step-by-step explanation:
if given f(-x)=x-7
f(-x)=x-7 => f(-(-x))=(-x)-7 =>f(x)= -x-7
f(h(x))=f(2x+3)= -(2x+3)-7 = -2x-3-7 = -2x-10
if given f(x)=x-7
f(h(x))=f(2x+3)=2x+3-7=2x-4
