Answer:

The possible values for X is: {0,1,2,3,....,12}

Yes, it is a discrete random variable.

Step-by-step explanation:

Consider the provided information.

We need to determine whether the variable is discrete or not.

Discrete variables are which can only take on a finite number of values.

Let the variable X be the number of unbroken eggs in a randomly chosen standard egg carton.

In a standard egg carton we can put 12 eggs.

Therefore, the possible values for X is: {0,1,2,3,....,12}

The number of unbroken eggs (X) can take infinite values, thus by the above definition it is a discrete random variable.

Which statement is true for the vertical number line? A. -2.5 is located below -3.5 . B. -4.8 is located below 4.8 . C. 3.25 is
meriva

Answer:

B. -4.8 is located below 4.8 .  TRUE

Step-by-step explanation:

The vertical line is called the Y - AXIS.

Here also, the integers are expressed as same as the horizontal axis.

.... -5, -4, -3, -2, -1 , 0 , 1 2,3 4,5 ....

In vertical line, If we move above 0, the value INCREASES.

If we move Below 0, the value DECREASES.

Now, consider the given cases:

A. -2.5 is located below -3.5 .

Here, as -3 lies Below -2.

So, -2 > -3 ⇒  -2.5  >  -3.5

So, -2.5 is located ABOVE 3.5.

B. -4.8 is located below 4.8 .

Here, as -4 lies Below 4.

So, 4 > -4 ⇒  4.8  >  -4.8

So, -4.8 is located BELOW 4.8.

C. 3.25 is located above 3.75 .

Here, 3.75  > 3.25  

⇒  3.75  is located ABOVE 3.25.

D. -0.5 is located below -1.5 .

Here, as -1.5 lies Below 0.5.

So, -0.5 > -1.5

⇒  -0.5  is located ABOVE -1.5.

E. 0 is located below -0.87 .

Here, as  -0.87  lies Below 0.

So,0  > -0.87

⇒  0  is located ABOVE-0.87.

A TV set contains five circuit boards of type A, five of type B, and four of type C. The probability of failing in its first 500
nekit [7.7K]

Answer:

0.903264

Step-by-step explanation:

Given that a TV set contains five circuit boards of type A, five of type B, and four of type C. The probability of failing in its first 5000 hours of use is 0.03 for a type A circuit board, 0.04 for a type B circuit board, and 0.03 for a type C circuit board.

Let A' = the event that A fails, B' =  B fails and C'= C fails.

Probability that no circuit board fails = Prob (A'B'C')

= P(A')P(B')P(C')  (since A,B, C are independent, their complements are independent

= (1-0.03)(1-0.04)(1-0.03)

= 0.903264

plz this is easy just answer Use < or > to compare the integers. –14 and –3 A. –14 > –3 B. –14 < –3
oee [108]
It would be B. because if you put the numbers on a number line, you notice that -14 is further down than -3 since -3 is closer to 0, so -14 is less than -3
