Answer:

its 12.08percent

Step-by-step explanation:

12.8 percent

What are the basic principles of probability?

Let's suppose the number of heads is r which represents the head times and in this case r = 4

Assuming that the coin is unbiased, you have the probability of success ‘p’(where p is considered as success)  [tex]\frac{1}{2}[/tex] and the probability of failure ‘q’ (where q is considered as failure).

The number of trials is represented by the ’n’ and here n = 12.

Now use the function for a binomial distribution:

P(R = r) = nCrprqn-r

P(R = 4) = (12C4)(1/2)4(1/2)12-4  

             = 495/4096

           =  [tex]\frac{495}{4096\\}[/tex]

           = 12.0849609%

Answer:

2 or b

Step-by-step explanation:

2 or b

The angles that are adjacent to angle 3 are angles 2 and 4

The adjacent angles of an angle are the angles next to the angle in the diagram

The given angle is angle 3.

This means that the adjacent angles of angle 3 are the angles beside angle 3

These angles are angles 2 and 4

Hence, the angles that are adjacent to angle 3 are angles 2 and 4

Answer:

1) PM < PQ + QM

2) PM < PR + MR

3) PM < 1/2 (PQ + PR + QR)

Step-by-step explanation:

This problem is based on the Pythagorean Theorum Equation

which states that a right triangle with sides a, b and hypotenuse can be written mathematically as hypotenuse = [tex]\sqrt{a^2 + b^2}[/tex]

We can rewrite each line segment of the diagram into variables to simplify this problem and use the Pythagorean equation:

Line PQ = Hypotenuse 1, Line PR = Hypotenuse 2, Line PM = Side B, Line QM = Side A, Line MR = Side C

With all the line segments simplified into variables you can separate the diagram into 2 seperate triangles. Triangle 1 has H1, A, B and Triangle 2 has H2, C, B

Using the Pythagorean equation for both triangles you get:

H1 = [tex]\sqrt{a^2 + b^2}[/tex]   and H2 = [tex]\sqrt {c^2 + b^2}[/tex]  

Now you can assign random values for each variable and compare the problem statements.

For Triangle 1 lets assign variables A = 1, B = 2, and H1 = [tex]\sqrt{1^2 + 2^2}[/tex] = [tex]\sqrt{3}[/tex] = 1.73  For Triangle 2 lets assign variables C = 3, B = 2 and H2 = [tex]\sqrt {3^2 + 2^2} = \sqrt {13}[/tex] = 3.6  

For the final step you can directly compare the statements and see which symbol is correct.

1) B ____ H1 + A is equivalent to  2  ____ (1.73 + 1),  which is turns out to be  2 < 2.73   The answer is  <

2) B ____ H2 + C is equivalent to 2 ____ (3.6 + 3), which turns out to be

2 < 6.6    The answer is < again

3) B ____ 1/2 (H1 + H2 + (A+C)  is equivalent to  2 _____ [1/2] (1.73 + 3.6 + 1 + 3), which turns out to be  2 < 4.67     The answer is <  again

Answer:

$1166.32

Step-by-step explanation:

We are given that

Total number of working days=20

Average speed of truck=45mph

Distance drive per day=350 miles

Distance traveled in 1 gallon=21 miles

Cost per gallon=$3.499

We have to find the money spend on gas

Total distance traveled in 20 days=[tex]350(20)=7000miles[/tex]

Total gas used in 20 days=[tex]\frac{7000}{21}[/tex]

Total gas used in 20 days=333.33 gallon

Cost of 333.33 gallon=[tex]3.499\times 333.33[/tex]

Cost of 333.33 gallon=$1166.32

Hence, money spend on gas last month=$1166.32

Answer:

a. [tex]\frac{3}{2}[/tex]

b. [tex]\frac{15\pi }{4}[/tex]

c. [tex]\frac{81\pi }{2}[/tex]

d. [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

P.S - The exact question is -

a. [tex]\int\limits^1_0 {3x} \, dx[/tex]

y = 3x

Shape of the given integral = A Triangle

Area of Triangle = [tex]\int\limits^1_0 {3x} \, dx[/tex] = [tex]\frac{1}{2}[/tex]×1×3 = [tex]\frac{3}{2}[/tex]

The graph of integral is as follows :

b.[tex]\int\limits^\15 _0 {\sqrt{15 - y^{2} } } \, dy[/tex]

x = [tex]\sqrt{15 - y^{2} }[/tex]

⇒x² = 15 - y²

⇒x² + y² = 15

⇒x² + y² = (√15)²

Shape of the integral = Quarter circle of radius √15

Area of Quarter circle = [tex]\int\limits^\15 _0 {\sqrt{15 - y^{2} } } \, dy[/tex] = [tex]\frac{1}{4}[/tex]×[tex]\pi[/tex]×r² = [tex]\frac{1}{4}[/tex]×[tex]\pi[/tex]×(√15)² = [tex]\frac{15\pi }{4}[/tex]

The graph of the following integral is as follows :

c.[tex]\int\limits^9_-9 {\sqrt{81 - x^{2} } } \, dx[/tex]

y = [tex]\sqrt{81 - x^{2} }[/tex]

⇒y² = 81 - x²

⇒y² + x² = 81

⇒y² + x² = 9²

Shape of the integral = Semi circle of radius 9

Area of semi circle = [tex]\int\limits^9_-9 {\sqrt{81 - x^{2} } } \, dx[/tex] = [tex]\frac{1}{2}[/tex]×[tex]\pi[/tex]×r² =  [tex]\frac{1}{2}[/tex]×[tex]\pi[/tex]×9² = [tex]\frac{81\pi }{2}[/tex]

The graph of the following integral is as follows :

d. [tex]\int\limits^7_0 {5 - \frac{y}{7} } \, dy[/tex]

x = 5 - [tex]\frac{y}{7}[/tex]

⇒[tex]\frac{y}{7}[/tex] = 5 - x

⇒y = 35 - 7x

At y = 0 , x = 5

At y = 7 , x = 4

Shape of the integral = A triangle

Area of Triangle = [tex]\frac{1}{2}[/tex]×(5-4)×7 =  [tex]\frac{1}{2}[/tex]×(1)×7 = [tex]\frac{7}{2}[/tex]

The graph of the integral is as follows :

Answer:

Standard form of [tex]f(x) =(x-3)^2 + 6[/tex] is [tex]\mathbf{x^2-6x+15}[/tex]

Step-by-step explanation:

Convert from vertex form to standard form [tex]f(x) =(x-3)^2 + 6[/tex]

If the vertex form is: [tex]a(x-h)^2+k[/tex]

The Standard form is: [tex]ax^2+bx+c[/tex]

Now, converting [tex]f(x) =(x-3)^2 + 6[/tex] into standard form

We know that: [tex](a-b)^2=a^2-2ab+b^2[/tex]

Using the formula:

[tex]f(x) =(x-3)^2 + 6\\f(x)=x^2-2(x)(3)+9+6\\f(x)=x^2-6x+15[/tex]

So, Standard form of [tex]f(x) =(x-3)^2 + 6[/tex] is [tex]\mathbf{x^2-6x+15}[/tex]

Answer: {-3, 0, 1, 9}

Step-by-step explanation:

We can think of a function as a "machine" that "eats" an input, and it transforms it into an "output". A more theoretical definition of a function is a relationship that maps elements of a given set (the domain, this is the set of the inputs) into only one element from another set (the range, this is the set of the outputs)

In the image, we can see that the elements {-3, 0, 1, 9} are mapped into the element {2}

Then the set of the inputs will be the set {-3, 0, 1, 9}

The correct option is the last one.

(B) There is likely an association between the categorical variables because the relative frequencies are not similar in value.  <======+ 100%

Step-by-step explanation:  Question?

.- A conditional relative frequency table is generated by column from a set of data. The conditional relative frequencies of the two categorical variables are then compared.

If the relative frequencies being compared are 0.21 and 0.79, which conclusion is most likely supported by the data?

The conclusion that should be supported is there is an association that lies between the categorical variables since the relative frequencies are not similar in value.

It is produced by the column form for setting out the data. It is of the two categorical variables that made for comparison.

In the case when the relative frequencies being compared are 0.21 and

0.79 so the above conclusion should be considered.

Answer:

The correct answer is the last choice. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.

Step-by-step explanation:

In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.

In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words, it didn't move.

In the last segment, it moved up again for 2 hours.

It travels for 2 hours, then stops for 1 hour, and finally travels again for 5 hours. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.

Distance is the total movement of an object without any regard for direction. We can define distance as how much ground an object has covered despite its starting or ending point.

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Answer: *for 8* Yes, It is congruent by SAS.

Step-by-step explanation:

Since we know that LM and NM are congruent, and that angles LMP and NMP are congruent, then all we need to do is prove that MP is congruent to MP, and we can do that by saying that MP is congruent to MP using the reflexive property.

When a polynomial P(x) is divided by (x+2), then the remainder is 1.
