klasskru [66]

The probabilities of each number are equal. Then statements A and C are correct.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Given

Pedro has a spinner with 4 sections numbered 1 through 4.

Pedro spins the spinner 100 times and records the results.

He calculates the relative frequency of each outcome.

Outcome                                 1                2              3               4

Relative Frequency             0.24          0.25        0.26          0.25

A)  A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment. This statement is correct.

B)  The theoretical probability that any one number is chosen is likely 0.20. This is incorrect because every number has an equal probability.

C)  It is likely that the spinner is fair. This statement is correct because the probabilities of each number are equal.

D)  The relative frequencies in the table are very different. This statement is incorrect. Because numbers 2 and 4 have the same frequency and the number 1 and 3 have slightly different frequencies.

Consider the following planes. 3x − 2y + z = 1, 2x + y − 3z = 3
prisoha [69]

Solve for any of the variables; for instance, z:

z=1-3x+2y

z=-\dfrac{3-2x-y}3

Then

1-3x+2y=-\dfrac{3-2x-y}3\implies11x-5y=6\implies\begin{cases}y=\frac{11x-6}5\\z=1-3x+\frac{22x-12}5\end{cases}

Let x=t; then the intersection is given by the vector-valued function

\vec r(t)=\left(t,\dfrac{11t-6}5,1-3t+\dfrac{22t-12}5\right)

or

\vec r(t)=\left(t,\dfrac{11t-6}5,\dfrac{7t-7}5\right)

Given that 2x+7=27 and 3x+1=28, does 2x+7=3x+1? explain.
Anastasy [175]
No, for thing 2x and 3x have different slopes. moreover they have different y and x intercepts. you can set them equal to find an intersection since they don't have the same slope but yea
