Answer:

Statistic

Step-by-step explanation:

A statistic is a sample of the whole mean like

E.x( how many pink doughnuts are in the dozen pack of doughnuts.

A parameter represent the whole mean

E.x( how many donuts were made at 7:00)

Since they are sampling 25 cars, it is a statistic.

Y= x^2 -5 solve for x
dexar [7]

Y= x^2 -5

We need to solve for x, we need to get x alone

Y= x^2 -5

Lets start by removing -5

Add 5 on both sides

y + 5= x^2 -5 + 5

y + 5= x^2

Now to isolate x , we need to remove the square from x

To remove square , take square root on both sides

+-\sqrt{y+5} = \sqrt{x^2}

square and square root will get cancelled

+-\sqrt{y+5} = x

So x = +\sqrt{y+5} and  x = -\sqrt{y+5}

Find the equation of a line parallel to y - 5x = 10 that passes through the point (3, 10). (answer in slope-intercept form)
NeX [460]
So, a line parallel to <span>y - 5x = 10, will have the same slope as that equation, so what is that slope anyway?  let's solve for "y".

</span>\bf y-5x=10\implies y=5x+10\implies y=\stackrel{slope}{5}x\stackrel{y-intercept}{+10}
<span>
alrite, so the slope is 5 then, well, then the parallel line will have the same slope.

so, we're really looking for the equation of a line whose slope is 5 and runs through 3,10.


</span>\bf \begin{array}{lllll}&#10;&x_1&y_1\\&#10;%   (a,b)&#10;&({{ 3}}\quad ,&{{ 10}})&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope = {{ m}}= \cfrac{rise}{run} \implies 5&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-10=5(x-3)&#10;\\\\\\&#10;y-10=5x-15\implies y=5x-5<span>

A positive integer is 5 more than 23 times another. Their product is 6732. Find the two integers.
inna [77]
Another way to write this is:
x = 23y + 5
xy = 6732

Now plug in the first equation into the second:
(23y + 5)y = 6732
23y^2 + 5y - 6732 = 0

Either use quadratic equation or factor:
(y - 17)(23y + 396) = 0
y = 17 or -396/23

You know you can automatically eliminate the second y because it's negative and you need the two integers to multiply to a positive number (6732).

Plug y = 17 back into either equation (second might be easier):
17x = 6732
x = 396
