What are endpoints of a line segment that divides the triangle defined by the vertices (2, 2), (8, 0), and (8, 4) into two congr

Art [367]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

triangle defined by the vertices (2, 2), (8, 0), and (8, 4)

We need to divide the triangle into two congruent triangles.

As we know that "Median " divides into two congruent triangles.

So, we will apply the formula of "Mid point of two coordinates":

So, Suppose (2,2) and (8,0)

$(\frac{2+8}{2},\frac{2+0}{2})\\\\(\frac{10}{2},\frac{2}{2})\\\\=(5,1)$

Suppose (2,2) and (8,4)

$=(\frac{8+2}{2},\frac{2+4}{2})\\\\=\frac{10}{2},\frac{6}{2})\\\\=(5.3)$

Hence, Option 'B' is correct.

A recent survey of 50 executives who were laid off during a recent recession revealed it took a mean of 26 weeks for them to fin

g100num [7]

Answer: $(24.28,\ 27.72)$

Step-by-step explanation:

Given : Sample size : $n=50$

Sample mean : $\overline{x}=26$

Standard deviation : $\sigma =6.2$

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

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

Formula to find the confidence interval for population mean :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=26\pm(1.96)\dfrac{6.2}{\sqrt{50}}\\\\\approx26\pm1.72\\\\=(26-1.72,\ 26+1.72)\\\\=(24.28,\ 27.72)$

Hence, a 95% confidence interval for the population mean = $(24.28,\ 27.72)$

You roll a fair 6-sided die 3 times. What is the likelihood of getting exactly one 4, exactly one 5, or exactly one 6

Whitepunk [10]

Answer:

Depends. Check out the explanation below.

Step-by-step explanation:

Depending on which number you choose, you will have the same chance for each of them. To find out the chance of each of them, you first need to find the denominator, which is 6 because there are 6 sides of a dice. Now, we need to find the numerator. How many sides are we looking at? 1? 2? 3? Depending on how many sides there are, is your probability. So, if there is one side you are trying to find, it would be 1/6. If there are two sides, it would be 2/6 or 1/3. And so on.
