Answer:  The correct answer is:  " n + 2 " .

____________________________________________

Step-by-step explanation:

____________________________________________

Let us assume that the:  "6) "  refers to "problem #6" .

____________________________________________

We are given the expression:

____________________________________________

 " -(-2-n) " ;   Let us simplify this expression;

To do so, we can "rewrite" this expression as:

              →           " -1(2 - n) " ;  

____________________________________________

Note the following distributive property of multiplication:

____________________________________________

      →  " a(b + c) =  ab + ac " .

____________________________________________

As such:  

     →  "  -1(-2 - n)  = (-1 * -2) + (-1 * -n) "  ;

                            =   (2)  +  (n)  ;

                            =   2 + n ;

                            ↔  " n + 2 " ;  which is our answer.

____________________________________________

Hope this answer — and explanation — is helpful to you!

          Wishing you well in your academic endeavors

                     — and within the "Brainly" community!

How many times will the string literal "Hi" appear in the lblMsg control? Dim intCount As Integer Do While intCount > 4 lblMs
4vir4ik [10]

Answer:

0

Step-by-step explanation:

In my opinion, the string won't display because, the intCount was not initialized before you started outputting the "Hi" string. So in order fro you to get the string to appear, the control point or value has to be initialized to maybe 0. then you can start looping from there. And if you are looping from the top or using greater than (>), The loop works best buy subtracting the control value else, you can end up with infinity loop.

Answer:

19/30

Step-by-step explanation:

1/5 + 2/15 + 3/10

We need the LCD of 5, 15, and 10.

LCD = 30

1/5 + 2/15 + 3/10 =

= 6/30 + 4/30 + 9/30

= 19/30

Sladkaya [172]

Answer:

a) 0.1423

b) 0.2977

c) 0.56

Step-by-step explanation:

For each driver stopped for speeding, there are only two possible outcomes. Either they have invalid licenses, or they do not. The probability of a driver having an invalid license is independent from other drivers. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

13 percent of the drivers stopped for speeding have invalid licenses.

This means that p = 0.13

14 drivers are stopped

This means that n = 14

(a) None will have an invalid license.

This is P(X = 0)

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{14,0}.(0.13)^{0}.(0.87)^{14} = 0.1423

(b) Exactly one will have an invalid license.

This is P(X = 1)

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{14,1}.(0.13)^{1}.(0.87)^{13} = 0.2977

(c) At least 2 will have invalid licenses.

Either less than 2 have invalid licenses, or at least 2 does. The sum of the probabilities of these events is decimal 1. Mathematically, this is

P(X < 2) + P(X \geq 2) = 1

We want P(X \geq 2)

So

P(X \geq 2) = 1 - P(X < 2)

In which

P(X < 2) = P(X = 0) + P(X = 1) = 0.1423 + 0.2977 = 0.44

P(X \geq 2) = 1 - P(X < 2) = 1 - 0.44 = 0.56
