Answer:

its 1

Step-by-step explanation:

Let's the length of rectangle x cm, then its width is (13-x) cm. since the area is 12 cm^2 we write:

(13-x)Xx=12

we get the width: x=1cm and the length is 13-12=1cm.

good day and be safe

What is an equation of the line that passes through the points (6, -7) and (-6, 3)?

Mars2501 [29]

Two point form:
y-(-7)/3-(-7)=x-6/-6-6
Rearrange to get y=-5/6x -2 (slope intercept form)
or y= 5x+6y=-12 (standard form)

The heights of the trees in a forest are normally distributed, with a mean of 25 meters and a standard deviation of 6 meters. Wh

Alla [95]

Answer:

2.3%

Step-by-step explanation:

The formula to convert x into z distribution is

$z=\frac{x-\mu}{\sigma}$

Where z is the test statistic

x is what we are looking for (in this case 37)

$\mu$ is the mean (in this case, it is 25)

$\sigma$ is the standard deviation (we have 6)

<em>Plugging these into the formula, we get:</em>

$z=\frac{x-\mu}{\sigma}\\z=\frac{37-25}{6}\\z=2$

Thus we can say we want $P(z\geq 2)$

<u>Note: </u> $P(z\geq a)=1-P(z\leq a)$

The table given is for any z where $P(z\leq a)$

Thus, now we have:

$P(z\geq 2)\\=1-P(z\leq 2)\\=1-0.9772\\=0.0228\\$

0.0228 into percentage is 0.0228 * 100 = 2.28%

Rounded, we get 2.3%

Third answer choice is right.
