Answer:

A ratio is basically how much of one thing there is compared to another thing. They can be showed using a colon like "3:1" or using the word "to" like "3 to 1" or lastly, they can also be shown as a fraction "3/1".

2 examples:

2:5

4 to 3

5/6

How does the increase in confidence level affect the interval width and margin of error?

meriva

Answer:

1. Three things influence the margin of error in a confidence interval estimate of a population mean: sample size, variability in the population, and confidence level. For each of these quantities separately, explain briefly what happens to the margin of error as that quantity increases.

Answer: As sample size increases, the margin of error decreases. As the variability in the population increases, the margin of error increases. As the confidence level increases, the margin of error increases. Incidentally, population variability is not something we can usually control, but more meticulous collection of data can reduce the variability in our measurements. The third of these—the relationship between confidence level and margin of error seems contradictory to many students because they are confusing accuracy (confidence level) and precision (margin of error). If you want to be surer of hitting a target with a spotlight, then you make your spotlight bigger.

5x + 6(x - 2) - 8 (x - 3)

Alex Ar [27]

Answer:

The value of $x=-4$ . The figure is also attached below.

Step-by-step explanation:

Considering the expression

$5x + 6(x - 2) - 8 (x - 3)$

If we have to find the vale of $x$ , then

$5x + 6(x - 2) - 8 (x - 3)=0$

$5x+6x-12-8\left(x-3\right)=0$

$5x+6x-12-8x+24=0$

$3x+12=0$

$\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}$

$3x+12-12=0-12$

$3x=-12$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3x}{3}=\frac{-12}{3}$

$x=-4$

Therefore, the value of $x=-4$ . The figure is also attached below.

30 POINTS By looking at the intercepts, which linear function does the graph represent?

larisa86 [58]

C. f(x)=2/3x-2

<h2>Explanation:</h2>

Looking at the graph we realize that the y-intercept is given by:

$b=-2$

The Slope-intercept form of the equation of a line is given by:

$y=mx+b$

So, our equation becomes:

$y=mx-2$

So the only option that matches a negative y-intercept is C. Let's see that the slope $m=2/3$ . Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from $x=-2$ to $x=0$ . In other words:

$Change \ in \ x=\Delta x=3 \\ \\ Change \ in \ y=\Delta y=2 \\ \\ \\ m=\frac{\Delta y}{\Delta x}=\frac{2}{3}$

Question 2

drek231 [11]

Answer:

y=-3x-5

Step-by-step explanation:

6x+2y=-10

2y = -6x-10 (you need to isolate the y and so i took 6x and subtracted it from both sides)

y = -6/2x-10/2 ( dont feel like explaining)

divide them (-6/2 and -10/2) to get

y=-3x-5

Hope i helped

Give an example of a repeating decimal where two digits repeat. Explain why your number is a rational number?

Assoli18 [71]

An example of a repeating decimal would be 6.78787878. a rational number is a number that can be represented a/b where a and b are integers and b isnt equal to 0, so a<span>ny decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number</span>
