Since we are given that
the mean is 15.2 oz
standard deviation of 0.5 oz
and simple random sample of 7
then we have an
<span>Exact normal distribution with mu equal to 15.2 and sigma equal to 0.4
since the samples are simple and random</span>

Let f(x) = x^2 - 5x +4 / x-1
Elenna [48]

Answer:

C. 3

Explanation:

You cannot divide by 0.

So plug in g(x) into f(x) in the denominator. The numerator is irrelevant so you don't need to worry about it.

Solve for what value of x will give you a denominator of 0.

I just eyeballed this and found that x=3 give you a denominator of 0.

or you can just plug in and check all the answer choice.

Who developed location theory?
kirill115 [55]
<span>Johann Heinrich von Thünen, a Prussian landowner, introduced an early theory of agricultural location in Der isolierte Staat (1826) (The Isolated State). The Thünenmodel suggests that accessibility to the market (town) can create a complete system of agricultural land use</span>

The equations of the tangent to the curve y=xsinx at the point (pi/2,pi/2) is
never [62]
The first thing you have to realize is that tangent is the slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:

\frac{d}{dx} xsin(x)

Next use product rule (I recommend watching videos if you're confused):

= [sin(x)] + [x*cos(x)]

Next substitute you x-value (π/2) into your derivative:

= [sin(  \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]
= 1 +  \frac{\pi}{2} *0
= 1

So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff) 

( \frac{\pi}{2}) =  1( \frac{\pi}{2}) + b
b = 0

So we get our equation:

y = x

So our answer is E

(25 POINTS) PLEASE HELP WILL GIVE BRAINLIEST, THANKS AND 5 STAR RATING!!!
bulgar [2K]

PYTHAGOREAN THEOREM\\c^{2} = a^{2} + b^{2}\\ b^{2}=c^{2} -a^{2}\\ a^{2} =b^{2}-c^{2}

1) x=9, because we can use the Pythagorean theorem, x^2 + 144 = 225, x^2 = 81

2) x=3\sqrt{8}, because 6^2 +6^2 = 72, \sqrt{72} = 3\sqrt{8}

3) x=2\sqrt{3}, because x^{2} +7=19\\x^{2} =12\\x= 2\sqrt{3}

hope this helps... load for images!
