"The frequency of an event uses counting numbers, but the __________________ of an event uses a percent or a number between 0 and 1."

Before finding the probabilities, we need to find all possible outcomes, and it's probabilities.

Doing this, we get:

The probability that a randomly selected pigeon gets an incorrect result is 0.0103 = 1.03%.

Possible outcomes:

Pigeon has the virus(1.5% probability) and gets an accurate test, showing the presence of the virus(97% probability).

Pigeon has the virus(1.5% probability) and gets an inaccurate test, not showing the presence of the virus(100% - 97% = 3% probability).

Pigeon does not have the virus(100 - 1.5 = 98.5% probability) and gets an accurate test, not showing the presence of the virus(99% probability).

Pigeon does not have the virus(98.5% probability) and gets an innacurate test, showing the virus(100 - 99 = 1% probability).

Probability of incorrect result:

Has the virus and test negative: 0.03 of 0.015

Does not have the virus and test positive: 0.01 of 0.985

Thus:

[tex]p = 0.03\times0.015 + 0.01\times0.985 = 0.0103[/tex]

The probability that a randomly selected pigeon gets an incorrect result is 0.0103 = 1.03%.

The bullet has been fired at an angle of 69.5° to the horizon. This is a problem based on the application of trigonometry.

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles.

Given that

Distance between the building and the man = 146 ft.

Height of the man = 5.9 ft.

Height of the building = 385 ft.

So,

Total height = Height of the man + Height of the building

                    = 5.9 ft. + 385 ft.

                    = 390.9 ft.

Let the angle to the horizon would the bullet have been fired be x°.

[tex]tanx^o = \frac{390.9}{146}\\tanx^o = 2.677\\x = tan^{-1}(2.677)\\x = 69.5[/tex]

Thus, the bullet has been at an angle of 69.5°.

Answer:

part a:

x lengths = 6

unit lengths = 2

part b:

6x+2

Step-by-step explanation:

You add the like terms, in this case, there are 6 x, so we have 6x, and two 1s, so 1+1= 2, and since 6x and 2 are not like terms, we can't add them, making our answer 6x+2

Answer:

Im past this subject, so this is what I remember. There are six x lengths, and I believe there are 2 NOT 8 unit lengths. For B the answer is 6x+2. Dont worry about the Brainly.

Answer:

59.7°

Step-by-step explanation:

Working based on the solution diagram :

The angle of elevation = x

From trigonometry :

Opposite side = 12 feets

Adjacent side = 7 feets

Tan x = opposite / Adjacent

Tan x = 12 / 7

Tan x = 1.7142857

x = tan^-1(1.7142857)

x = 59.744°

The angle of elevation from the duck is 59.7°

Answer:

The answer is 59.7 degrees

Answer:

32 meals

Step-by-step explanation:

Pounds of food per meal = 3/4 pounds

Pounds of food purchased = 24 pounds

Number of meals which the food can last up to, n = pounds of food purchased ÷ pounds of food per meal

n = 24 pounds ÷ 3/4 pounds

n = 24 * 4 /3

n = (24 * 4). / 3

n = 96 /3

n = 32 meals

Step-by-step explanation:

Hi,

f(x) = (x - 1) - 3

The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)

And the -3 is not embedded with the x, meaning the function will move 3 units down.

Perimeter=4y+4y+y+y

25=10y

We divide both sides with 10 => y=2,5

9514 1404 393

Answer:

Step-by-step explanation:

The perimeter is the sum of the side length. Each of the sides shown has the same length as its opposite, so the perimeter is ...

  P = 2(4y +y) = 10y

Using the given value for perimeter, we find y to be ...

  25 ft = 10y

  2.5 ft = y

__

Then the longer side is ...

  4y = 4(2.5 ft) = 10 ft . . . . length of longer side

x = 72

Step-by-step explanation:

∠DBC is an included angle and arc DB is its corresponding arc

Relationship between an included angle and its corresponding arc:  an included angle is equal to one half of its corresponding arc

so

∠DBC = [tex]\frac{1}{2}[/tex] arc DB

we are given that arc DB = 144

so we exchange arc db with 144

∠DBC = [tex]\frac{1}{2} 144[/tex]

[tex]\frac{1}{2} 144=72[/tex]

so we can conclude that ∠DBC (x) = 72
