Answer:

This is all I know

What is the interior angle of an 11 sided polygon?

about 147.27 degrees

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1620 degrees (from above)... And there are eleven angles... So, the measure of the interior angle of a regular 11-gon is about 147.27 degrees.

leva [86]

Answer:

Type I error occurs when the null hypothesis, H0, is rejected, although it is true.

Here the null hypothesis, H0 is:

H0: Setting weekly scheduled online interactions will boost the well being of people who are living on their own during the stay at home order.

a) A Type I error would be committed if the researchers conclude that setting weekly scheduled online interactions will not boost the well being of people who are living on their own during the stay at home order, but in reality it will

b) Two factors affecting type I error:

1) When the sample size, n, is too large it increases the chances of a type I error. Thus, a sample size should be small to decrease type I error.

2)A smaller level of significance should be used to decrease type I error. When a larger level of significance is used it increases type I error.

If FX) = 3x+6, which of the following is the inverse of Fx)?

LenaWriter [7]

Answer:

C. F'(x) = x - 6 / 3

Step-by-step explanation:

$y = 3x + 6$

$x = 3y + 6 \\ x - 6 = 3y + 6 - 6$

$\frac{x - 6}{3} = \frac{3y}{3}$

$y = \frac{x - 6}{3}$

$f1 = \frac{x - 6}{3}$

Answer:

3, 0, -5, -6

Step-by-step explanation:

when x= -8, f(x) = 8-5 or 3

when x= -5 f(x) = 5-5 or 0

when x= 0, f(x) = 0-5 or -5

when x=1, f(x) = -1-5 or -6

In a certain quiz that consists of 10 questions, each question after the first is worth 4 points more than the preceding questio

Artyom0805 [142]

Answer: The correct option is

(C) 26.

Step-by-step explanation: Given that in a certain quiz that consists of 10 questions, each question after the first is worth 4 points more than the preceding question.

All the 10 questions on the quiz are worth a total of 360 points.

We are to find the worth of the third question in points.

Since each question after the first is worth 4 points more than the preceding question, so this will make an arithmetic sequence with

first term a, common difference, d = 4 and number of terms, n = 10.

We know that, in an A.P. with first term a and common difference d,

$\textup{nth term, }a_n=a+(n-1)d,\\\\\textup{sum of first n terms, }S_n=\dfrac{n}{2}\{2a+(n-1)d\}.$

According to the given information,

$\textup{sum of first 10 terms, }S_n=360\\\\\Rightarrow \dfrac{10}{2}\{2a+(10-1)4\}=360\\\\\Rightarrow 5(2a+36)=360\\\\\Rightarrow 10(a+18)=360\\\\\Rightarrow a+18=36\\\\\Rightarrow a=36-18\\\\\Rightarrow a=18.$

Therefore, the third term of the sequence is

$a_3=a+(3-1)d=18+2\times4=18+8=26.$

Thus, the third question worth 26 points.

Option (C) is CORRECT.
