In which of the following should the random variable X not be modeled with a geometric distribution? A. According to a recent st
stiv31 [10]

The probability for success is not the same for each trial, then the option D cannot be modelled using a geometric distribution.

<h3>What is probability?</h3>

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

One of the assumptions to consider before the use of a geometric distribution can be valid is that, the probability of success must be the same for each outcome.

In the option D, selection is done without replacement, meaning that, the number total possible outcome will decrease as we make each selection and will also depend on how the colours are being chosen.

Hence, the probability of success will differ for each outcome, thus the option D is correct.

The roots of <img src="https://tex.z-dn.net/?f=10x%5E2-14x%2Bk" id="TexFormula1" title="10x^2-14x+k" alt="10x^2-14x+k" align="ab
Dafna11 [192]

Answer:

10

Step-by-step explanation:

10x²-14x+k = 0

x1 = sin a

x2= cos a

x1+x2 ≤ 2

x1. x2 ≤ 1 => k/10 ≤ 1

k ≤ 10

so the value of k should be 10

viva [34]
“If x = y, then x + 4 = y + 4” represents the additive property of equality. This means the same number is added on both sides of the equal sign.

Solve the literal equation 2a - b = 3b – a for a .<br> help pls ‍
VLD [36.1K]

Answer:

a = 4/3 b

Step-by-step explanation:

2a - b = 3b – a

Add a to each side

2a+a - b = 3b – a+a

3a -b = 3b

Add b to each side

3a -b+b = 3b+b

3a = 4b

Divide each side by 3

3a/3 = 4b/3

a = 4/3 b
