Answer:
30 is the wrong one because it is not a factor of 100
30 60 90 120
20 40 60 80 100
Step-by-step explanation:
Try doing 40 - 34 first:
40 - 34 = 6

We first standardise

:
P(1224 >

)=P(

)
which reduces to finding P(Z > 1.2) = 0.115
Answer:
172.5
Step-by-step explanation:
mean of men=sum/no of men
177=sum/30
sum=177*30
= 5310
mean of women=sum/no of women
164=sum/16
sum=164*16
= 2624
mean height= (5310+2624)/30+16
=7934/46
=172.5
Answer:
-10416.
Step-by-step explanation:
This is a Geometric Series with first term 4 and common ratio -5.
Sum of 6 terms = a1 . (r^6 - 1 )/ ( r - 1)
= 4 *( (-5)^6 - 1) / (-5-1)
= -10416 (answer).
