Answer 2

Answer:

a) x=26

b) x=2.7

Step-by-step explanation:

a) Mean = sum of all entries/ no. of entries

29 = 22+x+30+32+35/5

29 = 119+x/5

29×5=119+x. (cross multiplication)

145 = 119+x

145-119 =x

x= 26

b) 3.3 = 4.2+4.3+x+3.2+3.3+2.1/6

3.3= 17.1+ x/6

3.3 ×6 =17.1+x. (cross multiplication)

19.8 = 17.1+x

x= 2.7
