If 2 angles measure 43 and 48.....then the third angle measures (180 - (43 + 48) = 89......so ur 3 angles are 43, 48, and 89...because the angles of a triangle add up to 180 degrees.

This is an acute triangle......an acute triangle is a triangle that has all 3 angles that are  less then 90 degrees each.

Choose the correct answer below. A. Increasing the level of confidence has no effect on the interval. B. Increasing the level of
murzikaleks [220]

Answer:

ME = t_{\alpha/2} \frac{s}{\sqrt{n}}

And the width for the confidence interval is given by:

Width =2ME=2t_{\alpha/2} \frac{s}{\sqrt{n}}

And we want to see the effect if we increase the confidence level for a interval. On this case if we increase the confidence level then the critical value for the confidence interval t_{\alpha/2} would be higher and then the width of the interval would increase. So then the best answer for this case would be:

B. Increasing the level of confidence widens the interval.

Step-by-step explanation:

Let's assume that we have a parameter of interest \mu who represent for example the true mean for a population. And we can construct a confidence interval in order to estimate this parameter if we know the distribution for the statistic let's say \bar X and for this particular example the confidence interval is given by:

\bar X \pm ME

Where ME represent the margin of error for the estimation and this margin of error is given by:

ME = t_{\alpha/2} \frac{s}{\sqrt{n}}

And the width for the confidence interval is given by:

Width =2ME=2t_{\alpha/2} \frac{s}{\sqrt{n}}

And we want to see the effect if we increase the confidence level for a interval. On this case if we increase the confidence level then the critical value for the confidence interval t_{\alpha/2} would be higher and then the width of the interval would increase. So then the best answer for this case would be:

B. Increasing the level of confidence widens the interval.

Pamela's age is three times Jiri's age. The sum of their ages is 116. What is Jiri's age?
Sedbober [7]

Answer:

29

Step-by-step explanation:

Let Jiri's age be 'x'. Pamela's age is 3x since Pamela's age is three times Jiri's age.

The sum of their ages is 116:

x + 3x = 116

4x = 116

x = 116 ÷ 4 = 29

x = 29

Jiri's age is 29
