Step-by-step explanation:

There is always the same relationship

In other words: If we divide any quantity of one of the magnitudes by the one that corresponds to it in the other, the value it gives us is always the same. This value is known as the PROPORTIONALITY CONSTANT

What do z€ R mean for math as an answer to a inequality

Ksivusya [100]

Answer:

Its used for the domain and it means "the members of all REAL numbers" which refers to their being no imaginary number, for instance in inequalities that have square roots, it cant be a negative number otherwise you will get a imaginary number.

Which algebraic expression shows the average melting points of helium, hydrogen, and neon if h represents the melting point of h

Monica [59]

Given:
h = melting point of helium
j = melting point of hydrogen
k = melting point of neon

Number of values = 3
Therefore, the average is
(Sum of values)/(Number of values) = (h+j+k)/3

Answer:
The average melting point of helium, hydrogen, and neon is
(h+j+k)/3

Which table represents a nonlinear function?

klasskru [66]

I've Answered a question like this in the past (though it was linear) examples of a linear table are x:1234
and then y: -3 -5 -7 -9. so for a non linear table it would have to be odd numbers x:1234
y:3 6 12 24
remember my example and dont use 1234, -3 -5 -7 -9 ok?

An electronic product contains 40 integrated circuits. The probability that any integrated circuit is defective is 0.01, and the

neonofarm [45]

Answer:

There is a 33.10% probability that there is at least one defective integrated circuit.

Step-by-step explanation:

For either integrated circuit, there are only two possible outcomes. Either they are defective, or they are not. This means that we can solve this problem using the binomial probability distribution.

Binomial probability distribution

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

$P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}$

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

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

And $\pi$ is the probability of X happening.

In this problem

The electonic product contains 40 integrated circuits, so $n = 40$ .

The probability that any integrated circuit is defective is 0.01, so $\pi = 0.01$

What is the probability that there is at least one defective integrated circuit?

Either there is at least one defective integrated circuit, that is probability $P(X > 0)$ , or there are no defective integrated circuits, that is probability $P(X = 0)$ . The sum of these probabilities is decimal 1. We want to find $P(X>0)$ .
