How many triangles are formed by the angles and sides-unique triangle, no triangle, or many triangle
kirill115 [55]

No triangle formed

Solution:

Given data:

One angle is 45°

Another angle is 108°

One side is 7 cm

To find how many triangles are formed for the given data.

Let the unknown side of a triangle be x°.

Sum of all the sides of a triangle = 180°

45° + 108° + x° = 180°

⇒ x° = 180° – 45° – 108°

⇒ x° = 27°

There is no such angle can be formed with 27° in the given image.

Hence there is no triangle can be formed.

Suppose heights of seasonal pine saplings are normally distributed and have a known population standard deviation of 17 millimet
Mumz [18]

Answer:

296.693\leq x\leq 319.307

Step-by-step explanation:

The confidence interval for the population mean x can be calculated as:

x'-z_{\alpha /2}\frac{s}{\sqrt{n} } \leq x\leq x'+z_{\alpha /2}\frac{s}{\sqrt{n} }

Where x' is the sample mean, s is the population standard deviation, n is the sample size and z_{\alpha /2} is the z-score that let a proportion of \alpha /2 on the right tail.

\alpha is calculated as: 100%-99%=1%

So, z_{\alpha/2}=z_{0.005}=2.576

Finally, replacing the values of x' by 308, s by 17, n by 15 and z_{\alpha /2} by 2.576, we get that the confidence interval is:

308-2.576\frac{17}{\sqrt{15} } \leq x\leq 308+2.576\frac{17}{\sqrt{15} }\\308-11.307 \leq x\leq 308+11.307\\296.693\leq x\leq 319.307
