Answer:

Following are relation between Circle and Triangle:

1. Both circle and triangles are plane figures.

2. One circle is inscribed in a given triangle which is the largest circle that can be inscribed while Many triangle cane be inscribed in a circle. This circle is called incircle.

3. There also only one circle that passes through all vertices of a triangle. That circle is called circumcircle.

Answer:

The points are below.

Step-by-step explanation:

We have to tell  about the relationship between triangles and circle.

Several points are:

- Both circle and triangles are lane figures.

- Triangle has 3 vertices. On the other hand circle has infinitely many    vertices.

- Exactly one circle can be inscribed in a given triangle but many triangular shapes or triangles can be circumscribed in a given circle.

- Circles and triangles  both are geometric shapes or figures, and their areas can be calculated using certain formulas.

A chemist examines 12 sedimentary samples for bromide concentraction. The mean bromide concentration for the sample date is 0.43
Umnica [9.8K]

Answer:

a) z = 1.645

b) Lower endpoint: 0.422cc/m³

Upper endpoint: 0.452 cc/m³

Step-by-step explanation:

Population is approximately normal, so we can find the normal confidence interval.

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645. This is the critical value, the answer for a).

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.645*\frac{0.0325}{\sqrt{12}} = 0.015

The lower end of the interval is the sample mean subtracted by M. So it is 0.437 - 0.015 = 0.422cc/m³.

The upper end of the interval is the sample mean added to M. So it is 0.437 + 0.015 = 0.452 cc/m³.

b)

Lower endpoint: 0.422cc/m³

Upper endpoint: 0.452 cc/m³

You work with 3 other students on a project for science class. Your group
aleksandrvk [35]

Answer:

350 points are possible

Step-by-step explanation:

You take 329 divided by 94% or .94 to get 350.

100% of 350 is 350

To double check, 94% of 350 is 329 & 6% of 350 is 21.  329 +21 = 350
