What is the distance between two points with coordinates at (8, 40) and (20, 5)?

Alchen [17]

Answer:

37 units

Step-by-step explanation:

The two points form a right triangle so

a²+b²=c² so

(8-20)²(x values)+(40-5)²(y values)=c² (distance) so

12²+35²=c² so

144+1225=c²

1369=c²

c=37 units

Answer: $(0.164,\ 0.276)$

Step-by-step explanation:

The confidence interval of population proportion is given by :-

$\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

Given : Sample size : $n=150$

The proportion of individuals lease a car : $hat{p}=\dfrac{33}{150}=0.22$

Significance level : $\alpha: 1-0.9=0.1$

Critical value : $z_{\alpha/2}=1.645$

Then, the confidence interval of population proportion is given by :-

$0.22\pm (1.645)\sqrt{\dfrac{0.22(1-0.22)}{150}}\\\\\approx0.22\pm0.056=(0.164,\ 0.276)$

Hence, the confidence interval for the population proportion with a 90% confidence level= $(0.164,\ 0.276)$
