Answer:

Option 1: 0.32

Step-by-step explanation:

Let

P(A) be the experimental probability of getting two

And

P(B) be the experimental probability of getting three

The dice is rolled 360 times.

So the sample space is n(S) = 360

P(A) = n(A)/n(S)

= 54/360

= 0.15

And

P(B) = n(B)/n(S)

= 62/360

= 0.172

As both the events A and B are mutually exclusive,

P(A or B)  = P(A) + P(B)

= 0.15 + 0.172

=0.322

Rounding of to one decimal gives us:

0.32

So the probability of rolling a two or three is 0.32 ..

Answer:

option C is the correct answer

Step-by-step explanation:

System A:                                                  System B:

-x - 2y = 7    ........(1)                               -x - 2y = 7    .......(3)  

5x - 6y = -3  ........(2)                                  -16y= 32  ........(4)

Solution for system A: ( -3, -2)

For option A

Multiply the first equation by 3

3(- x - 2y) = 3(7)         ⇒     - 3x - 6y = 21 ........... (5)

Add equation 2 and 5

  5x - 6y = -3

- 3x - 6y = 21

  2x -12y = 18   ⇒  2( x - 6y ) = 2( 9 )    ⇒   x - 6y = 9

Option A is not equal to equation in system B so now we check option B.

 For option B

Multiply the first equation by -5

-5(- x - 2y) = -5(7)         ⇒    5x + 10y = -35 ........... (6)

Add equation 2 and 6

  5x - 6y = -3

  5x + 10y = -35

  10x + 4y = -38   ⇒   2( 5x + 2y ) = 2(-19)    ⇒  5x + 2y = -19

Option B is not equal to equation in system B so now we check option C.

For option C

Multiply the first equation by 5            

5(- x - 2y) = 5(7)         ⇒   - 5x - 10y = 35 ........... (7)

Add equation 2 and 7

  5x - 6y = -3

- 5x - 10y = 35

    0 - 16y = 32   ⇒   -16y = 32

Option C is equal to equation in system b so now we check if the solution to system B is same as system A.  

Solution to system B:

First, we find value of y from equation 4:

-16y = 32   ⇒    y = [tex]\frac{32}{-16}[/tex]   ⇒    y = -2

Now, we put value of y in equation 3 to find value of x:

-x - 2y = 7  ⇒  -x - 2(-2) = 7   ⇒  -x + 4 = 7   ⇒  -x = 7 - 4  ⇒  -x = 3

multiply both sides by -1

-1 × (-x) = -1 × (3)       ⇒     x = -3

Solution of system B = (-3, -2)

Solution of system B is the same as system A, so option C is correct.

Answer:

It's 35

Step-by-step explanation:

I took a test that had this question on it and it said this was the right answer.

Different combination to pulls out 4 coins each time from 7coins is equals to 35.

" Combination is defined as the selection of the objects from the given set where arrangement of order does not matter."

Formula used

[tex]nC_{r} = \frac{n!}{(n-r)!r!}[/tex]

According to the question,

Total number of coins 'n' = 7

Number of coins pulls out each time 'r' = 4

Substitute the value in the formula to get different combination,

[tex]7C_{4} = \frac{7!}{(7-4)!4!}[/tex]

      [tex]= \frac{(7)(6)(5)(4!)}{(3!)(4!)} \\\\=\frac{(7)(6)(5)}{(3)(2)(1)}\\\\=(7)(5)\\\\=35[/tex]

Hence, different combination to pulls out 4 coins each time from 7coins is equals to 35.

ANSWER

|SU|=3ft

EXPLANATION

Triangle TSU is an isosceles right triangle.

Because one of the angles in the right triangle is 45°.

This means that the third angle is also 45°.

This implies that that |ST|=|SU|

The reason is that isosceles triangle has the base angles equal and the arms on these angles are equal.

Answer:

[tex]2x^\frac{5}{3} - 4y^\frac{3}{4}[/tex]

Step-by-step explanation:

Given equation:

[tex]\sqrt[3]{8x^5} - \sqrt[4]{256y^3}[/tex]

([tex](8x^5)^\frac{1}{3} - (256y^3)^\frac{1}{4} \\ (8^\frac{1}{3}  . x^\frac{5}{3} ) - (256^\frac{1}{4}. y^\frac{3}{4})\\ 2x^\frac{5}{3} - 4y^\frac{3}{4}[/tex] !

The initial equations of (3√8x^5) and (4√256y^3) are first changed to exponential form and then simplified to final forms of 6x^2√x and 64y respectively. The final simplified form of the entire equation therefore becomes 6x^2√x - 64y.

The given expression is (3√8x^5) - (4√256y^3). Lets breakdown and simplify each component firstly.

The first expression, 3√8x^5, can be written as 3*(8x^5)^(1/2). The number 8 can be expressed as 2^3 and x^5 as (x^2)^(5/2). So, 3√(8x^5) simplifies to 3*2x^2*√(x) = 6x^2√x.

For the second expression, 4√256y^3, can be written as 4*(256y^3)^(1/2). The number 256 can be expressed as 2^8 and y^3 as (y^2)^(3/2). So, 4√(256y^3) simplifies to 4*16y = 64y.

Now, putting these values back into the original equation, we get: 6x^2√x - 64y

7.25 is the Mean.

Median is the number that is directly in the middle so just count inwards from each side after you ordered your data set. If you get two numbers just add them both and divide by two.

Answer:

6

Step-by-step explanation:

To solve for e, it must be alone on one side of the equation

Your equation is:

e/2 = 3

To get rid of the divided by 2, you multiply both sides by 2 since multiplication is the opposite of divison.

So:

e/2 = 3

[Multiply both sides by 2]

e = 6

In this triangle the length of the side adjacent to the 55 degree angle is x, and the length of the hypotenuse is 20

So:

[tex]cos(55\°) = \frac{x}{20}[/tex]

Now we solve the equation to find the value of x

To simplify 8³ on a scientific calculator, input 8, press the exponentiation key, enter 3, and press '=' to get the result of 512, or 5.12 x 10² in scientific notation.

Explanation:

To simplify 8² using a scientific calculator, you would typically follow these steps:

Ensure that the calculator is turned on and in the correct computational mode.

Enter the number 8.

Press the exponentiation key, often labeled as '^', 'exp', or represented by a caret symbol.

Enter the number 3 to represent the power to which you are raising 8.

Press the '=' or 'Enter' key to execute the calculation.

The calculator will give you the answer, which is 512. When simplifying further, if we were to represent this number in scientific notation, it would be written as 5.12 times 10², as it has three significant figures.

For distributions C and D, the median represents the centre most accurately.

Given that the median is a robust statistic—that is, skewed data and outliers have little effect on it—it is the best estimate of centre for skewed or outlier-filled distributions.

Since the mean is not robust, it serves as a useful proxy for the centre in symmetric distributions.

Answer B has a uniform distribution, whereas answer A has a distribution that is nearly symmetric.

Given that the right tail is longer than the left, solution D appears to have a right-skewed distribution, while answer C has a left-skewed distribution.

Answer:

The longest bread stick is approximately 16 in

Explanation:

The diagram representing the tray is shown in the attached image

From the diagram, we can note that the diagonal of the tray represents the hypotenuse of a right-angled triangle having legs 9.5 in and 13 in

Therefore, to get the length of the hypotenuse, we can use the Pythagorean equation which is as follows:

c² = a² + b²

where c is the length of the hypotenuse and a and b are the length of the two legs

Substitute with the givens in the above equation to get the length of the hypotenuse as follows:

c² = (9.5)² + (13)² = 259.25

c = 16.1 in which is approximately 16 in

From the above, we can conclude that:

The longest bread stick that can be fit straight along the diagonal of the tray is approximately 16 in

Answer:

16 m < P < 19 m

Step-by-step explanation:

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x----> the length of the third side

Applying the triangle inequality theorem

1) 3+8 > c

11 > c

c < 11 m

2) c+3 > 8

c> 5 m

so

the measure of the third side must be

5 m < c < 8 m

therefore

The perimeter of the triangle is equal to

P=3+8+c

P=11+c

The inequality is equal to

(11+5) m < P < (11+8) m

16 m < P < 19 m
