Answer:

1-sphere

2-Triangular pyramid

3-cube

4-Triangular prism

5-Cylinder

6-Rectangular pyramid

7-Cone

8-Rectangular prism

Step-by-step explanation:

We have to match description with their correct solid name.

1.3 D figure where all points are the same distance from the center is called sphere.

1-sphere

2.3 D figure made of all triangles.That figure is called triangular pyramid.

2-Triangular pyramid

3.3 D figure with six congruent squares is called cube.

3-cube

4.3 D figure with two triangle bases and rectangles for the rest of its faces.That figure is called triangular prism.

4-Triangular prism

5.3 D figure with circular bases is called cylinder.

5-Cylinder

6.3 D figure with a rectangle as a base and triangle for the rest of its bases.

That figure is called rectangular pyramid.

6-Rectangular pyramid

7.3 D figure with one circular base and one vertex.That figure is called cone.

7-Cone

8.3 D figure with rectangles for all of its faces.That figure is called rectangular prism or cuboid.

8-Rectangular prism

Sergeeva-Olga [200]

Answer:

q = 14

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Equality Properties
  • Complementary Angles: Angles that add up to 90°

Step-by-step explanation:

<u>Step 1: Set up equation</u>

<em>The 2 angles must add up to 90°.</em>

(4q - 5)° + 39° = 90°

<u>Step 2: Solve for </u><u><em>q</em></u>

  1. Combine like terms:                    4q + 34 = 90
  2. Subtract 34 on both sides:          4q = 56
  3. Divide both sides by 4:                q = 14

Consider the e-billing case. The mean and the standard deviation of the sample of n = 65 payment times are xbar= 18.4730 and s =
Travka [436]

Answer: The null and the alternative hypotheses are given below:

H_{0}:\mu=18.6

H_{a}:\mu

Under null hypothesis, the test statistic is:

z=\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

        =\frac{18.4730-18.6}{\frac{3.9045}{\sqrt{65}} }

        =-0.26

\therefore z=-0.26

Now we have to find the left tailed critical value at 0.01 significance level using the standard normal table.

The critical value is:

z_{critical}=-2.33

Since the test statistic is -0.26 lies in acceptance region because the critical region is beyond -2.33, therefore, we fail to reject the null hypothesis.
