<u>Restando la cantidad utilizada de el total</u>, tiene-se que 7470 clavos le quedan.
----------------------
- En total, para la construcción, Samuel compró 7,943 clavos.
- De toda esta cantidad, 473 fueron utilizadas.
- La cantidad de clavos que le quedan es la <u>subtracción da cantidad total por la utilizada</u>, o sea, 7943 restado de 473.
Le quedan 7470 clavos.

Answer:
-t2+10t-h+8 = 0
Step-by-step explanation:
(a) If <em>f(x)</em> is to be a proper density function, then its integral over the given support must evaulate to 1:
For the integral, substitute <em>u</em> = <em>x</em> ² and d<em>u</em> = 2<em>x</em> d<em>x</em>. Then as <em>x</em> → 0, <em>u</em> → 0; as <em>x</em> → ∞, <em>u</em> → ∞:
which reduces to
<em>c</em> / 2 (0 + 1) = 1 → <em>c</em> = 2
(b) Find the probability P(1 < <em>X </em>< 3) by integrating the density function over [1, 3] (I'll omit the steps because it's the same process as in (a)):
The temperature went up by 33° fahrenheit because -8+8=0 and 0+25= 25 so 8+25=33
