Answer:
<u><em>p = 1.5 & s = 7</em></u>
Step-by-step explanation:
7. =
0.45(14) = 4.2p ⇒ Cross-multiply the terms
6.3 = 4.2p
p = ⇒ Divide 6.3 by 4.2 to get <em>p </em>by itself (solve for <em>p</em>)
p = 1.5
8. =
2.4s = 6(2.8) ⇒ Cross-multiply the terms
2.4s = 16.8
s = ⇒ Divide 16.8 by 2.4 to get <em>s </em>by itself (solve for <em>s</em>)
s = 7

Usando el concepto de pendiente, se encuentra que el cambio en la distancia horizontal es de 10 pies.
La pendiente de una reta es la <u>razón entre el cambio vertical y el cambio horizontal,</u> o sea, cual el cambio vertical cuando el cambio horizontal es de 1.
En este problema, hay que:
- La pendiente es -100, o sea, cuando hay un desplazamiento de un pie por adelante, hay una queda de 100 pies.
- Bajado 1000 pies, entonces, aplicando la proporción:
1 pie H -> -100 pies V
x pie H -> -1000 pies V
Aplicando la multiplicación cruzada:
El cambio en la distancia horizontal es de 10 pies.

Answer:
b. As the sample size â increases, the variance of decreases. â So, the distribution of becomes highly concentrated around.
Step-by-step explanation:
Let : Yi,.... Yn are = i.i.d are random variables. The probability density of the distribution varies along with the sample size. When the sample size changes, the probability density of also changes.
The probability distribution may be defined as the statistical expression which defines the likelihood of any outcome for the discrete random variable and it can be opposed to the continuous random variable.
In the context, when the size of the sample of the distribution size increases, it causes a decrease in the variance and so the distribution becomes highly concentrated around.
