Answer:

HL Theorem

Step-by-step explanation:

If you look at the graph, the single line on both hypotenuses shows that they are equivalent. The double lines show that the two sides are equal. Because it is given that a hypotenuse and leg are equal, the hypotenuse-leg theorem applies.

If it was two legs instead, it would have been Side-Angle-Side

To find the standard deviation of the diameter of wooden dowels, the manufacturer measures 19 randomly selected dowels and find

loris [4]

Answer:

Option D - $[0.12$

Step-by-step explanation:

Given : The manufacturer measures 19 randomly selected dowels and finds the standard deviation of the sample to be s=0.16.

To find : The 95% confidence interval for the population standard deviation sigma?

Solution :

Number of sample n=19

The degree of freedom is Df=n-1=19-1=18

The standard deviation of the sample is s=0.16

Applying chi-square table to find critical value,

Upper critical value of $\chi^2$ is $UC=\chi(\frac{0.05}{2},18) = 31.5264$

Lower critical value of $\chi^2$ is

$LC=\chi(1-\frac{0.05}{2},18) = 8.2307$

Lower limit of the 95% confidence interval for the population variance

$L=\frac{(df)\times (s^2)}{UC}$

$L=\frac{18\times (0.16^2)}{31.5264}$

$L=\frac{18\times0.0256}{31.5264}$

$L=\frac{0.4608}{31.5264}$

$L=0.0146$

Upper limit of the 95% confidence interval for the population variance

$U=\frac{(df)\times(s^2)}{LC}$

$U=\frac{18\times (0.16^2)}{8.2307}$

$U=\frac{18\times0.0256}{8.2307}$

$U=\frac{0.4608}{8.2307}$

$U=0.0559$

So, The 95% confidence interval for the population variance is [0.0146, 0.0560]

Now, The 95% confidence interval for the population standard deviation is

$[\sqrt{0.0146}$

$[0.1208$

or $[0.12$

Therefore, Option D is correct.

The 95% confidence interval for the population standard deviation is $[0.12$

Find the 15th term of the arithmetic sequence if a1 = -3 and d = 2

pantera1 [17]

Answer:

Step-by-step explanation:

a1 = - 3 Given

d = 2 Given

n = 15 Given

Formula

tn = a1 + (n - 1) * d

Substitute and solve

t15 = -3 + (15 - 1) * 2 Calculate what's in the brackets.

t15 = -3 + 14*2 Combne

t15 = -3 + 28 Add the two terms

t15 = 25
