What is the sum of the first 10 terms in the geometric sequence -3 6 -12 24 -48

vlada-n [284]

Use the formula for the sum of a geometric sequence:
Sum = (a(r^n - 1))/(r - 1)
where a is the first term, -3
r is the common ratio, -2
and n is the number of terms

Thus,
Sum = ((-3)((-2)^10 - 1))/(-2-1) = 1023

damaskus [11]

Answer:

0.2700

Step-by-step explanation:

-Notice that this is a binomial distribution with p=0.52, n=4 and x=3.

-The formula for the binomial probabilities is given as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

The probability than in 4, exactly 3 order their food on the go is:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=3)={4\choose3}0.52^3(1-0.52)^1\\\\=0.2700$

Hence, the probability that exactly 3 order their food on the go is 0.2700
