Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

3(−10n+9)−3(1+8n)=24

Step 1: Simplify both sides of the equation.

3(−10n+9)−3(1+8n)=24

(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)

−30n+27+−3+−24n=24

(−30n+−24n)+(27+−3)=24(Combine Like Terms)

−54n+24=24

Step 2: Subtract 24 from both sides.

−54n+24−24=24−24

−54n=0

Step 3: Divide both sides by -54.

−54n/-54=0/−54

What 3 consecutive integers equal 84

Murrr4er [49]

First represent your 3 consecutive integers as follows.

X ⇒ first integer

X + 1 ⇒ second integer

X + 2 ⇒ third integer

Since their sum is 84, our equation reads x + (x + 1) + (x + 2) = 84.

Simplifying on the left side we get 3x + 3 = 84.

Now subtract 3 from both sides to get 3x = 81.

Dividing both sides by 3, we find that x = 27.

Finally, make sure you list all your answers.

If x is 27 then x + 1 is 28 and x + 2 is 29.

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:

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