Answer:

  44 votes

Step-by-step explanation:

The fourth contestant will get 17 votes (4 more than the 3rd contenstant). The total votes cast are then ...

Complete Question

The complete question is shown on the first uploaded image

Answer:

The  correct option is F

t =  1.17

t_ {\alpha , df} =t_ {0.10 , 8} = 1.86

Since the test statistics<u> is outside </u>the rejection region , <u>we fail to reject </u>the null hypothesis ,There<u> is no</u>  statistically significant evidence to reject the claim

Step-by-step explanation:

From the question we are told that

    The  claim is  \mu =  0

Hence  

      The  null hypothesis is  H_o  :  \mu = 0

       The  alternative is  H_a  :  \mu  \ne  0

Generally the test statistics is mathematically represented as  

                 t =  \frac{\= d - \mu_d }{ \frac{s_d}{ \sqrt{n} } }

=>              t =  \frac{3.5 -0 }{ \frac{8.94}{ \sqrt{9} } }

=>              t =  1.17

Generally the degree of freedom is mathematically represented as

      df  =  n- 1

      df  =  9 -  1

      df  =  8

From the student t-distribution table  the critical value of  \alpha at a degree of freedom of  8 is  

          t_ {\alpha , df} =t_ {0.10 , 8} = 1.86

Since the t_ {\alpha , df} is  outside the rejection region , we fail to reject the null hypothesis ,There is no sufficient evidence to reject the claim

If a polygon has 36 angles, what is it called?
DanielleElmas [232]
<h2>Answer: 36-gon (also called triacontakaihexagon) </h2>

Let's start by explaining that a polygon is a closed geometrical figure composed from three or more lines. These lines (sequence of straight segments) are the sides of the polygon, and the points where they intersect are called vertices that form their angles.

It should be noted that its name comes from the Greek word <em>polygōnon</em> (many angles), since the angles (although the sides are used, as well) are those that will define the name the polygon will have.

In this sense, for a polygon that has 36 angles, its name is 36-gon, and formally named as triacontakaihexagon or triacontahexagon (sometimes the Greek word <em>kai</em> that serves as connector, is omitted).

C = d where C is the circumference of a circle, is about 3.14, and d is the diameter.
Rzqust [24]

Answer:

Formula for Circumference of a Circle

Circumference is given by the formula C = πd where π = 3.14 and d is the diameter of the circle. Circumference is given by the formula C = 2πr where π = 3.14 and r is the radius of the circle.

Hope it's helpful to you

what do i write for this " Write a problem that requires adding 1 to the quotient when interpreting the remainder."
Mariana [72]
You should write a ( real world situation ) question that can only have whole numbers as a solution because you would divide and then you can not have a fraction left over so instead you add one. For instance there are 132 students going on a field trip. 20 students can fit on each bus. how many buses are needed? 7 because when you divide 132 by 20 you get 6 remainder 12. You can not just make 12 students walk to the location so you would add an extra bus.
