Zoe is doing a survey to find the time her classmates spend playing video games. She asks the following question:

2 answers:

7 0

The data she would collect would be grouping people depending on how much video games they played.

This however, is not a statistical question. Instead, she should set for example: 1-3 hrs per week, 4-6 hrs, etc. People play different amounts of hours, and so you cannot set a specific number, it must be a "range-of-numbers".

Also the question itself is kinda judging and comparative

so overall, umm... this question isn't really good

hope this helps :D

Answer:

A) It is expected that she collects data in a table like follows:

hours played weekly | number of students

0 | 2

1 | 3

2 | 5

... | ...

B) The question is not a statistical question because a single answer is expected. A statistical question would be <em>How many hours do students spend playing video games? </em> and the answer would be the average of the previously collected data.

12 + x to the power of 4 - 6 when x = 8

iren [92.7K]

value of $12+x^4-6$ at x=8 is $5002$ .

<u>Step-by-step explanation:</u>

here we need to evaluate 12 + x to the power of 4 - 6 when x = 8 or , $12+x^4-6$ where x=8 . Let's find out:

⇒ $12+x^4-6$

Putting x =8 :

⇒ $12+8^4-6$

Splitting 8 to power 4 into 8 to power 2 ( 2 times )

⇒ $12+8^2(8^2)-6$

⇒ $12+64(64)-6$

⇒ $12+4096-6$

⇒ $4096+6$

⇒ $5002$

Therefore , value of $12+x^4-6$ at x=8 is $5002$ .

Hillside orchard grows Fiji apples and Gala apples. There are 160 Fiji apple trees and 120 Galla apple trees in the orchard. Hil

Paul [167]

Answer:

190

Step-by-step explanation:

160 - 120 = 40

120 + 30 = 150

150 + 40 = 190

Can someone help plsss!

Roman55 [17]

Well the y-intercept is +2

And the slope of the blue line is 1/2

So y=1/2x+2

Slope is rise/run (up then ((right)))

And the intercept is found where the line intercects the y line.

Show that every triangle formed by the coordinate axes and a tangent line to y = 1/x ( for x > 0)

vfiekz [6]

Answer:

Step-by-step explanation:

given a point $(x_0,y_0)$ the equation of a line with slope m that passes through the given point is

$y-y_0 = m(x-x_0)$ or equivalently

$y = mx+(y_0-mx_0)$ .

Recall that a line of the form $y=mx+b$ , the y intercept is b and the x intercept is $\frac{-b}{m}$ .

So, in our case, the y intercept is $(y_0-mx_0)$ and the x intercept is $\frac{mx_0-y_0}{m}$ .

In our case, we know that the line is tangent to the graph of 1/x. So consider a point over the graph $(x_0,\frac{1}{x_0})$ . Which means that $y_0=\frac{1}{x_0}$

The slope of the tangent line is given by the derivative of the function evaluated at $x_0$ . Using the properties of derivatives, we get

$y' = \frac{-1}{x^2}$ . So evaluated at $x_0$ we get $m = \frac{-1}{x_0^2}$

Replacing the values in our previous findings we get that the y intercept is

$(y_0-mx_0) = (\frac{1}{x_0}-(\frac{-1}{x_0^2}x_0)) = \frac{2}{x_0}$

The x intercept is

$\frac{mx_0-y_0}{m} = \frac{\frac{-1}{x_0^2}x_0-\frac{1}{x_0}}{\frac{-1}{x_0^2}} = 2x_0$

The triangle in consideration has height $\frac{2}{x_0}$ and base $2x_0$ . So the area is

$\frac{1}{2}\frac{2}{x_0}\cdot 2x_0=2$

So regardless of the point we take on the graph, the area of the triangle is always 2.
