What graph represents f(x) = 0.5(4)x

vampirchik [111]

Answer:

See attached picture

Step-by-step explanation:

The equation f(x) = 0.5(4)x is most likely $f(x) = 0.5(4)^x$ . This is an exponential. To graph the function, test the points -1, 0, and 1. Then connect.

$f(x) = 0.5(4)^{-1}=0.5(\frac{1}{4}) = \frac{1}{8}$

$f(x) = 0.5(4)^{0}=0.5(1) = 0.5$

$f(x) = 0.5(4)^{1}=0.5(4) = 2$

A customer from Cavallaro's Fruit Stand picks a sample of 5 oranges at random from a crate containing 75 oranges, of which 6 are

boyakko [2]

Answer:

0.341 is the probability that the sample contains 1 or more rotten oranges.

Step-by-step explanation:

We are given the following information:

We treat rotten as a success.

Number of oranges = 75

Number of rotten orange = 6

P(Rotten orange) =

$=\dfrac{6}{75} = 0.08$

Then the number of rotten oranges follows a binomial distribution, where

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

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 5

We have to evaluate:

$P(x \geq 1) =1 - P(x = 0)\\\\=1- \binom{5}{0}(0.08)^0(1-0.08)^5\\\\= 1 - 0.659\\= 0.341$

0.341 is the probability that the sample contains 1 or more rotten oranges.
