Which function is a linear function?
natali 33 [55]

Answer:

B) y + 7 = 5x

Step-by-step explanation:

In math, a linear function is one that has a graph that is a line. It looks like this: There are two things that make up the equation: y = f(x) = a + bx. One independent variable and one dependent variable make up a linear function, which is also called a simple function. The independent variable is x, and the dependent variable is y, which is what you're interested in. Also, there are no exponents in a linear function, which means the exponent is one.

An election forecasting model has a 50:50 chance of correctly predicting the election winner when there are two candidates. Befo
Blababa [14]

Answer:

Te correct answer is c) 0.750

Step-by-step explanation:

Lets call:

A = {Allan wins the election}

B = {Barnes wins the election}

MA = {the model predicts that Allan wins}

MB = {the model predicts Barnes wins}

We know that the model has a 50:50 chance of correctly predicting the election winner when there are two candidates. Then:

P(MA | A) = 0.5 = P(MA | B)

P(MB | B) = 0.5 = P(MB | A)

The prior probability P(A) given by the election researcher is 0.75

We must find the posterior probability P(A | MB)

We use Bayes theorem:

P(A|MB) = \frac{P(MB|A)P(A)}{P(MB)} = \frac{0.5*0.75}{0.5} = 0.75

We used the result:

P(MB) = P(MB|A)P(A) + P(MB|B)P(B) = 0.5*0.75+0.5*0.25=0.5

In line 53, the author of Passage 2 uses quotation
notsponge [240]

(E) "cast doubt on the aptness of a description"

Writers will occasionally include a term or phrase in quotation marks to question its veracity. The author of paragraph 2 denigrates the learning theorists by putting the word "experts" in quotation marks because of their "shocking" estimate of canine intelligence.

The answer is not (A). One may contend that the author's use of quote marks conveys surprise or even irritation. (B) is the wrong answer. The term "experts" being surrounded by quotation marks is not a show of "respect," but rather of suspicion.

The answer is not (C). There is no need to doubt the plain usage of the word "experts" in this context, even when the author may have reservations about the theories of the experts. D is likewise a poor choice.
