Answer:
0.5
Step-by-step explanation:
the first significant figure is the non zero
Answer:
its letter A
Step-by-step explanation:
Total number of integers = 5
median
= (5+1)/2 th observation
= 3 rd observation
therefore the 3rd number = 13
now let the other number be x
total sum = 1+3+13+x+22 = 39+x
ATQ
(39+x)/5 = 16
39+x = 80
x = 41
the numbers are -
1,3,13,22,41
Answer:
the first term is a1
the distance between the numbers is d
we have:
a5 = a1 + 4d = 23
a12 = a1 + 11d = 72
so we have the equation:
a1 + 4d = 23
a1 + 11d = 72
=> a1 = -5
d = 7
=> an = -5 + 7(n - 1) = 7n - 12
with an = 7n - 12
=> a2 = 2
a3 = 9
so the first three terms is -5; 2; 9
