Mariana is taking a multiple choice test with a total of 80 points available. Each question is worth exactly 4 points. What woul
Sladkaya [172]

Mariana's score if got right if she got 5 wrong is 60 points.

Mariana's score if got right if she got xx wrong is 80 - 4xx.

<h3>What is Mariana's score?</h3>

The first step is to determine the number of questions that Mariana got right. In order to get the number of questions that she got right, subtract the total number of number of questions from the questions that he got wrong.

Questions that Mariana got right = total number of questions - questions he got wrong

Total number of questions = total number of points / point of each question

Total number of questions = 80 / 4

Total number of questions = 20

Questions that Mariana got right if he got 5 wrong = 20 - 5 = 15

Mariana's score = questions she got right x number of points per question

Mariana's score = 15 x 4 = 60 points

Questions that Mariana got right if he got x wrong = 20 - xx

Mariana's score = (20 - xx) x 4

Mariana's score = 80 - 4xx

BRAINLY AWARDED TO FIRST TO ANSWER
kirza4 [7]
The correct answer is that the variable does have a binomial distribution; P(success)=0.5; the number of trials is 5.

This is binomial because it has a fixed number of trials, the trials are independent of each other, the probability of success is constant from trial to trial, and there are only 2 outcomes.  

Since success is getting an even number, and there are 3 even numbers out of 6, P(success)=3/6=0.5.

There are 5 trials because you are rolling the cube 5 times.

Simplify the expression. What classification describes the resulting polynomial?
valentinak56 [21]

Answer:

A quadratic Trinomial

Step-by-step explanation:

hope this helps

Given

(3x² - 11x - 4) - (2x² - x - 6)

Distribute both parenthesis, noting the second is distributed by - 1

= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms

= x² - 10x + 2 ←  this is a quadratic with 3 terms, thus trinomial → A

HELP PLEASE !!!!!!!!!!!
horrorfan [7]

Answer:

option B

Step-by-step explanation:

\lim_{x\to \infty} f(x) =  \lim_{x \to \infty} (log(x+2)-3 )

                    =  \lim_{x \to \infty} ( log(x+2)) - \lim_{x \to \infty} 3\\\\=\infty - 3\\\\= \infty

\lim_{x \to 2} f(x) =  \lim_{x \to 2} ( log(x+2)) - \lim_{x \to2} 3\\\\

                 = log( 2 + 2 ) - 3\\\\= log 4 - 3\\\\=log(2^2) -3\\\\=2 log 2 -3

\lim_{x \to -2} f(x) =  \lim_{x \to -2} ( log(x+2)) - \lim_{x \to -2} 3\\\\  \lim_{x \to -2}_+ f(x) = \lim_{x \to -2_+} ( log(x+2)) - \lim_{x \to -2_+} 3 = -\infty\\\\\lim_{x \to -2_-} f(x) =  \lim_{x \to -2}_- ( log(x+2)) - \lim_{x \to -2}_- 3 = -\infty\\\\\\\lim_{x \to -2} f(x) =  - \infty
