Sum of interior angles of polygon = 180(n - 2) = 180(5-2) = 180(3) = 540

x + 121 + 108 + 102 + 100 = 540

x + 431 = 541

x = 540 - 431

x = 109

Answer

x = 109°

Interior Angle Sum = 180 (n - 2) ; where n is number of sides

Sum = 180 (5 - 2)

= 180 (3)

= 540

100° + 102° + 108° + 121° + x = 540°

431° + x = 540°

x = 109°

Suppose that a is a one-dimensional array of ints with a length of at least 2. Which of the following code fragments successfull

elixir [45]

Answer:

E)II and III only

Step-by-step explanation:

This can be seen with examples. Say a[0]=1 and and a[1]=2.

for I , the first line of code would be:

a[0]=a[1];

thus, we would get a new value for a[0]=2.

The second line of code

a[1]=a[0]; uses the new value of a[0], so we would get a[1]=2.

The end result is a[0]=2, and a[1]=2 which doesn't exchange the values of the first two elements.

For II the first line of code

int t= a[0]; saves the original value of a[0] to t, so we get t=1.

the second line of code

a[0]=a[1]; changes the value of a[0] to that of a[1]. Thus, in our example a[0]=2.

the final line

a[1]=t; changes the value of a[1] to the original value of a[0], giving us a[1]=1 and a[0]=2, what we were looking for.

For III

the first line of code

a[0]=a[0]-a[1];

gives us

a[0]=1-2

the secon line

a[1]=a[1]+a[0];

takes the new value of a[0] and replaces it in the expression

a[1]= 2+(1-2)=1

the last line

a[0]=a[1]-a[0];

takes the new value of a[0] and a[1] and replaces the in the expression

a[0]=1-(1-2)=1-1+2=2

which exchanges the values needed.

So we can see that only II and III do what we require, giving us E as the answer.

Place each of the digits 1, 3, 5, and 6 in the blanks provided to create an expression whose value is 1/10

kompoz [17]

Answer:

$\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}$

Step-by-step explanation:

From the picture attached,

Multiplication of two fractions gives the result as $\frac{1}{10}$ .

This shows that the denominator of the fractions when multiplied with each other results a number that will be the multiple of 10.

Therefore, from the given numbers,

5 × 6 = 30

Rest two numbers be placed as the numerator of the fractions.

$\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}$

$=\frac{1}{10}$

Therefore, $\frac{1}{5}\times \frac{3}{6}=\frac{1}{10}$ will be the answer.

Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people ans

elena-s [515]

Answer:

The questions are

What does the frequency column in the attached table sum to?
What does the relative frequency column in attached table sum to?
What is the difference between relative frequency and frequency for each data value in the attached table?
What is the difference between cumulative relative frequency and relative frequency for each data value in attached table?

The correct answers are

65
1
The relative frequency gives the relative proportion of each frequency in the sample while
The frequency is the observed number of count of each grouping has in a given sample size

Step-by-step explanation:

1. The frequency column in the attached column sums up to 65 because it is the total number of sales persons selected

2. The relative frequency column in the attached table sum up to 1 because it is the sum of the fractions of the individual frequencies to the total frequency

3. The difference between relative frequency and frequency for each data value is that

The relative frequency gives the relative proportion of each frequency in the sample while

4. The frequency is the observed number of count of each grouping has in a given sample size
