Triangle ABC has side lengths: AB = 3.5 cm, BC = 2.4 cm, and AC = 4.2 cm ΔABC ≅ ΔHJK What is the length of side HJ?

1 answer:

4 1

For this you'll want to draw out Triangle ABC and label it as the problem gives you.

Draw a similar triangle to the first one you drew and label it the exact same way as "ABC" and then match the measurement "AB" to "HJ".

Hope this helps.

Answer: A 95 % confidence interval for $\sigma^2$ :-

$2.90$

A 95 % confidence interval for $\sigma$ :-

$1.70$

Step-by-step explanation:

Given : Sample size : $n=5$

Standard deviation : $\sigma : 2.84$

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

We assume this is normal distribution

By using chi-square distribution, the critical value will be :-

$\chi^2_{n-1,\alpha/2}=\chi^2_{4,0.025}=11.14$

$\chi^2_{n-1,1-\alpha/2}=\chi^2_{4,0.975}=0.48$

The confidence interval for population variance:-

$\dfrac{(n-1)s^2}{\chi^2_{n-1\alpha/2}}$

$=\dfrac{(2.84)^2(4)}{11.14}$

For standard deviation just take square root in the above inequality,

$\sqrt{2.90}$
