Table
x f(x)
-2 0.2
-1 0.4
0 0.8
1 1.6
2 3.2
Look that the pair of data (0, 0.8), it means f(0) is 0.8
Given
that a^0 = 1, means that the coefficient of the function has to be 0.8
and you discard the first and the third options.
You have to replace the values of x in the equations and compare the results.
For f(x) = 0.8 * (2^x) you get
x f(x) = 0.8 * (2^x)
-2 0.8 * (2^-2) = 0.8 / 4 = 0.2
-1 0.8 * (2^-1) = 0.8 / 2 = 0.4
0 0.8 * (2^0) = 0.8 * 1 = 0.8
1 0.8 * (2^1) = 0.8 * 2 = 1.6
2 0.8 * (2^2) = 0.8 * 4 = 3.2
As you can see these results are the same of the table of the question, so the function is f(x) = 0.8 (2^x).
Answer: f(x) = 0.8 * (2^x)

Answer:
choice C) 1:3 and 33 1/3%
Step-by-step explanation:
Binomial distribution will be used to know the probability that the total weight of the samples will exceed 530 pounds.
It is given that the rocket that will return the rock and soil samples to Earth cannot lift off if the total weight of the samples from the rovers exceeds 530 pounds.
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p). A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a sequence of outcomes is called a Bernoulli process; for a single trial, i.e., n = 1, the binomial distribution is a Bernoulli distribution. The binomial distribution is the basis for the popular binomial test of statistical significance.
