Answer: p = 120 degrees

Step-by-step explanation:

Figure a shows a pentagon. The sum of interior angles in a pentagon is equal to 540 degrees.

1. Subtract the known numerical angle

540 - 60 = 480

All of the remaining angles (represented by the variable p) are equal to one another. Therefore, we can use the expression 4p = 480 to find the value of p.

2. Evaluate the equation to find the value of p.

4p = 480

p = 120

Answer:

416

Step-by-step explanation:

Given that:

A previous random sample = 4000

Sample mean = 2250

[tex]\hat p = \dfrac{x}{n}[/tex]

[tex]\hat p = \dfrac{2250}{4000}[/tex]

[tex]\hat p = 0.5625[/tex]

The confidence interval level = 90%

Desired Margin of error E = 0.04

The level of significance at 90% C.I  = 1 - 0.90 = 0.10

The critical value [tex]Z_{\alpha/2} = Z_{0.10/2}[/tex]

[tex]\implies Z_{0.05} = 1.645[/tex]   ( From the  z tables)

[tex]n = \hat p \times (1- \hat p ) \bigg ( \dfrac{z_{0.05}}{E} \bigg)^2[/tex]

[tex]n = 0.5625 \times (1- 0.5625) \bigg ( \dfrac{1.645}{0.04} \bigg)^2[/tex]

[tex]n = 0.5625 \times (0.4375) \bigg ( 41.125 \bigg)^2[/tex]

n = 416.21

Thus, the number of citizens required to be sampled is [tex]\simeq[/tex] 416

Answer:

11

Step-by-step explanation:

Answer:

The answer is 11.

Step-by-step explanation:

I found this answer due to a simple problem. If Johnny has 6 apples and 5 oranges, how much fruit does he have in total? The answer is 11, because you add the numbers 5 and 6 to get 11.

First we need to know what a bisector is. A bisector is a line that divides an object into equal parts. So, If we know that line L is a bisector line, we know that PA = PB.

Hope this Helps!!! :)

Given :

Trina and Jessie went on a vacation to Hawaii. Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level.

Jessie went hang-gliding and reached an altitude of 87.9 meters, which is above sea level.

To Find :

The distance between them.

Solution :

Distance between them is :

[tex]D=87.9-(-85.6)\ m\\\\D = 173.5\ m[/tex]

Therefore, maximum distance between them is 173.5 m.

Hence, this is the required solution.

Answer:

false

Answer:

This question is false.

Step-by-step explanation:

Answer: b. four fifths plus two fourths

Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.

Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.

4/5  20/5 = 4    4×4 = 16   so 4/5 is equivalent to 16/20

2/4   20/4 = 5    5×2 = 10   so  2/4 is equivalent to 10/20  

Add:    16/20 + 10/20 = 26/20

Answer:

0

Step-by-step explanation:

this is because the two numerals are the same only one is negative so they cancel out and equal 0

Answer:

The answer is 0

Step-by-step explanation:

The answer is 0 because -9+9 is just like putting 9-9.

9-9 = -9+9.

Answer:

y = [tex]-\frac{2}{9}x+\frac{61}{9}[/tex]

Step-by-step explanation:

Let the equation of the new railroad track passing through the point [tex](x_1,y_1)[/tex] and slope = m₁ is,

[tex]y-y_1=m_1(x-x_1)[/tex]

Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the line passing through (-3, 1) and (6, -1) will be,

m₂ = [tex]\frac{1+1}{-3-6}[/tex]

m₂ = [tex]-\frac{2}{9}[/tex]

Since, railroad track and the given line are parallel,

m₁ = m₂ = [tex]-\frac{2}{9}[/tex]

Therefore, equation of the railroad track passing through (8, 5) and slope = [tex]-\frac{2}{9}[/tex] will be,

y - 5 = [tex]-\frac{2}{9}(x-8)[/tex]

y = [tex]-\frac{2}{9}x+\frac{16}{9}+5[/tex]

y = [tex]-\frac{2}{9}x+\frac{61}{9}[/tex]

Answer:

± 5.919

Step-by-step explanation:

Margin of Error formula = z × standard deviation/√n

Z score for 99% confidence interval = 2.58

n = 19

Standard deviation = 10

Margin of Error = 2.58 × 10/√19

= ± 5.9189259339

Approximately to 3 decimal place = ± 5.919

Answer:

12 gallons of paint

Step-by-step explanation:

Sasha can paint 400 square feet using 1 gallon of paint

If she needs to paint 4,704 square feet, then she will need to purchase 4,704 / 400 = 11.76 gallons of paint. Since she can only purchase paint in whole gallons, she will need to purchase 12 gallons of paint (we have to round up).

Answer:

The two equations are

r = 600m

and

r/600 = m
