Answer:
1,804
Step-by-step explanation:
106 - 60 = 44
44/2 = 22
60 + 22 = 82
82*22 = 1,804
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]-by-
Answer:
8
Step-by-step explanation:
Given that in a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10
Mean = 6
Since mean = 6 we get sum of all the 6 scores = 
Now II part says 10 is changed to 20
i.e. original sum = 36
Changed value = 10
Adjusted value =26
Add: new value =22
New sum =48
So we have sum = 48
New mean= 
(This can also be done using the formula
old mean + positive change in one score/6)
Sn=sum of the n terms of the geometric sequence.
a= the first term
r=the common ratio
n=numbers of terms.
Sn=a[(1-r^n)/(1-r)]
In this case:
a=-3
r=a₂/a₁=15/-3=-5
n=9
S₉=-3[(1-(-5)⁹) / (1-(-5))=
S₉=-3(1+1953125)/6)=
S₉=-3(1953126/6)=
S₉=-3(325521)
S₉=-976563

Answer:
C
Step-by-step explanation:
16, 8, 4, 2, …
a = 16
r = 8/16 = ½
f(x) = 16 × (½)^(x - 1)
