If EG = 2u + 9 and EI = 5u - 48, find EI in parallelogram FGHI.

zalisa [80]

Answer:

47

Step-by-step explanation:

The diagonals of a parallelogram bisect in their middle point, so :

2u + 9 = 5u - 48

3u = 57

u = 19

EI = 5* 19 - 48 = 47

The heights of a random sample of 100 women are recorded. The sample mean is 65.3 inches and the sample standard deviation is 3

Keith_Richards [23]

Answer: B. $65.3\pm(2)(0.3)$

Step-by-step explanation:

The confidence interval for the population mean is given by :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size : n= 100

Sample mean : $\overline{x}=65.3\text{ inches}$

Standard deviation: $\sigma=3 \text{ inches}$

Level of confidence = 0.95

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Then, 95% confidence interval for the population mean will be :-

$65.3\pm (1.96)\dfrac{3}{\sqrt{100}}\\\\\approx65.3\pm(2)(\dfrac{3}{10})=65.3\pm(2)(0.3)$
