Determine the critical value(s) of the test statistic for each of the following small sample tests for the population mean where
Fiesta28 [93]

Answer:

Step 1  t  = - 2.552

Step 2 t   =  1.356

Step 3  two values     t  =  - 2.12 on the left   and   t = 2.12 on the right

Step-by-step explanation:

Normal Distribution

size sample  < 30

Table to use  t-student table

a)  left-tailed test       α  =  0,01            n = 19      gl   = 19 -1      gl = 18

Directly from  t table      

t  = - 2.552

b) Right-tailed test     α  = 0,1     n  = 13     gl  = 13 - 1    gl =12

Directly from  t table

t  = 1.356

c)  Two-tailed test   α  = 0,05   but two tails means   we use α/2

    α/2  =  0,025    n = 17   gl  = n - 1   gl  = 17  -1     gl  = 16

From table:

t =  - 2.12  on the left tail  and  t = 2.12 on the right tail

A model of a soccer ball is made up of regular pentagons and hexagons.
Monica [59]

<em>An </em><em>apothem</em><em> is a line from the center of a regular polygon at right angles to any of its sides.</em>

<u>For part A</u>,

We want to find area of pentagon (5 sided figure) given apothem is 1.38 in and side length as 2 inch.

If we look at the picture shown (attached), we can see that a triangle is formed. What is the area of this triangle?

A=0.5bh\\A=0.5(1)(1.38)\\A=0.69 square inches

<u><em>How many such triangles are there in a pentagon? 10. So we multiply 0.69 by 10 to get total area of pentagon.</em></u>

Area of Pentagon = 0.69*10=6.9 square inches.


<u>For part B</u>,

We want to find area of hexagon (6 sided figure) given apothem is 1.73 in and side length as 2 inch.

If we look at the picture shown (attached), we can see that a triangle is formed. What is the area of this triangle?

A=0.5bh\\A=0.5(1)(1.73)\\A=0.865 square inches

<em><u>How many such triangles are there in a hexagon? 12. So we multiply 0.865 by 12 to get total area of hexagon.</u></em>

Area of Hexagon = 0.865*12=10.4 square inches.


ANSWER:

Area of Pentagon is 6.9 square inches.

Area of Hexagon is 10.4 square inches.

The area of the poster is (x^2+2x-15) inches the width is (x-3) inches calculate the dimensions of the poster board when x=14
givi [52]

Answer:

The poster is 11 inches wide and 19 inches in height.

Step-by-step explanation:

We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:

((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.

Therefore:

Height= 19 Inches

Width= 11 Inches

Total Area= 209 Square Inches

In a right triangle sin A=
kherson [118]

Answer:

sinA=\frac{opposite}{hypotenuse}

Step-by-step explanation:

Soh-cah-toa is a great way to remember:

sin=\frac{opposite}{hypotenuse}\\ cin=\frac{adjacent}{hypotenuse}\\ tan=\frac{opposite}{adjacent}

You just remember the first letters : sine= opposite/hypotenuse , for example.
