Answers

Answer:

The given numerical value  is a Parameter.

Step-by-step explanation:

Given - For a certain movie 64.3% of the 112 members of the audience were females.

To find - Determine whether the underlined numerical value is a parameter or a statistic.

Proof -

Given that, 64.3% of the 112 members of the audience were females.

Now,

64.3% of  112 = [tex]\frac{64.3}{100}*112[/tex] = 72.016

Since it is not a perfect number

And Human can not be in fraction

So,

The given numerical value  is a Parameter.

Solve for X. What does X equal?

Answers

Step-by-step explanation:

Apply angle sum of triangle, that means the sum of all interior angles in a triangle is equal to 180°.

So that, (x + 45) + 50° + 90° = 180°.

However when we simply do 45+50+90, the answer is already bigger than 180.

So the question is made wrong.

If you’re solving the equation for X then X = -5

write the equation of lines shown on the graph.

How many numbers must be selected from the set left curly bracket 1 comma 2 comma 3 comma 4 comma 5 comma 6 comma 7 comma 8 comma 9 comma 10 right curly bracket in order to guarantee that at least one pair adds up to 11

Answers

Answer:

6 numbers

Step-by-step explanation:

Given

[tex]x = \{1,2,3,4,5,6,7,8,9,10\}[/tex]

Required

Pairs that add up to 11

The pairs are:

[tex]x = \{\{1,10\},\{2,9\},\{3,8\},\{4,7\},\{5,6\}\}[/tex]

In the above set, we have:

[tex]n(x) =5[/tex]

Using pigeonhole principle

This principle implies that, there is at least 1 more pair.

Hence, the numbers that must be selected to guarantee the required sum of 11 is:

[tex]n= 5+1[/tex] --- The 1 represents (at least 1 more)

[tex]n=6[/tex]
