Show that 6 – 4x - x^2 can never be greater than 10.<br> ( This is an Additional Math Question )
notsponge [240]

Answer:

see explanation

Step-by-step explanation:

Given

6 - 4x - x²

Since the coefficient of the x² term < 0 then parabola has a maximum vertex.

To find the x- coordinate of the vertex

x_{vertex} = - \frac{b}{2a}

with a = - 1 and b = - 4 , then

x_{vertex} = - \frac{-4}{-2} = - 2

The corresponding y- coordinate is found by substituting x = - 2 , that is

6 - 4(- 2) - (- 2)² = 6 + 8 - 4 = 10

vertex = (- 2, 10 )

The maximum value of the function is the y- coordinate of the vertex

Then maximum value is 10

Thus 6 - 4x - x² is never greater than 10

Glenda checks the computer monitors made at her company for defects. It has been shown that 0. 5% of the monitors are defective.
Y_Kistochka [10]

The statement that will make this process into a binomial experiment is that "C. Glenda checks the monitors until she has 300 non-defective monitors."

<h2>Given that</h2>

Glenda checks the computer monitors made at her company for defects.

It has been shown that 0.5% of the monitors are defective.

She decides to check several monitors and record if they are defective.

<h3>We have to determine</h3>

Which of the following will make this process into a binomial experiment?

<h3>According to the question</h3>

A binomial experiment is defined as a statistical experiment that consists of n repeated trials.

<h3>Only two possible outcomes are possible in each trial- either a success or a failure. </h3>

Here the probability of success remains the same on every trial.

The mean sampling proportion gives the mean value for the proportion of success based on the given sample size, n. Hence, the most appropriate interpretation is For all samples of size 100, the mean of all possible sample proportions of monitors manufactured that have a screen defect is 0.5%.

Hence, ''Glenda checks the monitors until she has 300 non-defective monitors."

Answer:

Page 1:

1. 450

2.36

3.279

4.81

5.This would affect the final answers because then each section could have more or less students.

6.No, because if you don't know how many students are in one category then there is a very big array of different numbers that could be in that one category.

Page 2:

1.Less, because just by looking at the yellow section you can see that it does not cover at least half of the chart.

2. 48%

3.550

4.44

5.264

6.77

7.66

8.No because if you know the value of one category then you can't determine the other percentages because they could be anything.

Page 3:

1.42%

2.300

3.45

4.27

5.18

6.7 times more people said popcorn is their favorite movie snack than hot dogs.

7. I added the percentages I know and then subtracted that number from 100 to get the percentage of popcorn.

Step-by-step explanation:

I included the explanation for answers that required in the answer and this took a long time to complete. I hope I could help!
