Mathematics
1 answer:
aalyn [17]3 years ago

Answer:

1.B 2.H 3. A

Step-by-step explanation:

1. First, find out the percentage of people who voted for Mathematika in survey one.

The total amount of people who voted is 14+17+19, which equals 50. 17/50 people voted for Mathematika, 17/50 = 0.34.

To find out how many people out of 300 will vote for Mathematika, multiply the 0.34 by 300. 300 x 0.34 = 102, so 102 people will vote for Mathetika.

2. You use the same logic for number 2. 14+17+19+20+19+11 = 100, so 100 people voted in total. 34 people voted for Infinitus. 34/100 = 0.34. Multiply 0.34 by 750 to get 255 people will vote for Infinitus.

3. The mean = the average. To find the average, add up all of the numbers, then divide that number by the amount of numbers added together.

7+9+11+13+15 = 55

5 numbers were added together so you divide 55 by 5

55/5 = 11. The mean is 11

9+10+11+12+13 = 55

There were 5 numbers added together

55/5 = 11. Both the means were the same

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.
liberstina [14]

Correct answer is A.

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.

<h3>How to calculate the diameter?</h3>

If you know the radius of the circle, multiply by 2 to get the diameter. The radius is the distance from the center of the circle to the edge. For example, if the radius of a circle is 4 cm, then the diameter is 4 cm x 2 = 8 cm. If you know the circumference of the circle, divide by π to get the diameter.

<h3>Briefing:</h3>

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction which is A.

The diameter of the circle is used for the square as l=2r therefore corresponds to the diameter, while for a hexagon r=r being the radius of the circle.

I understand that the question you are looking for is:

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.

A) The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.

B) The radius of the circle is used for the square construction, but the diameter of the circle is used for the regular hexagon construction.

C) The square will need two arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.

D) The square will need six arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.

Mumz [18]
Introduce the following notations of events:
A "The person has the disease"
B "The test is positive", C "the test is erroneous"
Our formula will be then:
P(A)=P(A!B)P(B)+P(A!C)P(C)\\\text{Using the given value we get the formula:}\\0.18=P(A!B)0.9+0.06\times0.1\\\text{Solving the above equation for P(A!B) we get:}\\P(AB):0.19
So the probability we are looking for is 0.19

here the 3 decimal place is '3' and using the 4rth decimal place we determine wether it will be '3' or the next num '4' .

The 4rth place is '4'(as it is lesser than 5) the 3rd decimal place will become 3.

I hope im right and i hope I am understood
