Will mark brainliest

Anna007 [38]

Answer: $x\leq 3$

PLEASE MARK ME BRAINLIEST

Step-by-step explanation:

1) Simplify both sides of the inequality:

$4x+8\geq 5x+5$

2) Subtract $5x$ from both sides:

$4x+8-5x\geq 5x+5-5x$

3) Simplify:

$-x+8\geq 5$

4) Subtract $8$ from both sides:

$-x+8-8\geq 5-8$

5) Simplify:

$-x\geq -3$

6) Divide both sides by $-1$ :

$\frac{-x}{-1} =\frac{-3}{-1}$

7) Simplify:

$x\leq -3$

For a binomial process, the probability of success is 40 percent and the number of trials is 5. Find the standard deviation.

Yakvenalex [24]

Answer:

$Sd(X) =\sqrt{1.2}=1.095$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=5, p=0.4)$
