Answer:
the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5.
Step-by-step explanation:
According to the Central Limit Theorem, assuming the sampling is random and sample size is big enough (≥30) the mean of the sampling distribution is the population mean.
Therefore the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5
Answer:
El área es 2 veces el cuadrado del ancho del rectángulo.
Step-by-step explanation:
El área de un rectángulo viene dado por:
![A = a*l](https://tex.z-dn.net/?f=%20A%20%3D%20a%2Al%20)
En donde:
a: es el ancho
l: es el largo
Si el largo es el doble del ancho:
![l = 2a](https://tex.z-dn.net/?f=%20l%20%3D%202a%20)
Entonces el área es:
![A = a*l = a*(2a) = 2a^{2}](https://tex.z-dn.net/?f=%20A%20%3D%20a%2Al%20%3D%20a%2A%282a%29%20%3D%202a%5E%7B2%7D%20)
Por lo tanto, el área es 2 veces el cuadrado del ancho del rectángulo.

Step-by-step explanation:
Answer:
$110
Step-by-step explanation:
The computation is shown below:
Provided that
Number of desk purchased Fund Left $
0 700
1 590
2 480
3 370
4 260
5 150
6 40
Now the Fund decreased while purchasing is
= 5 desks - 2 desks
= 3 desks
i.e
= $480 - $150
= $330
Now the amount of money left for decreased the desk fund is
![= \frac{Fund\ decreased }{number\ of\ desk\ decreased}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7BFund%5C%20decreased%20%7D%7Bnumber%5C%20of%5C%20desk%5C%20decreased%7D)
![= \frac{\$330}{3\ desk}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B%5C%24330%7D%7B3%5C%20desk%7D)
= $110
