There could be 150 sequences of rolls

Let's find the sets of 5 integers less than or equal to 6 that could multiply to 300 (where order doesn't matter for right now):

1, 2, 5, 5, 6

1, 3, 4, 5, 5

2, 2, 3, 5, 5

Now let's find the number of unique ways we could reorder these sets

There are

5!/2!=60 ways to order {1, 2, 5, 5, 6}

There are

5!/2! =60 ways to order {1, 3, 4, 5, 5}

There are

5!/2!2! =30 ways to order {2, 2, 3, 5, 5}

There could have, therefore, been 60 + 60 + 30 = 150 different sequences of rolls

The amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

The meaning of unit price is a price quoted in terms of so much per agreed or standard unit of product or service

Given that, a woman bought 1.8 kg of chicken and 1.6 kg of meat. The chicken cost $5.40 and the meat cost $6.40,

We need to find, if she had bought 2.4 kg of chicken and 2 kg of meat, how much would she have had to pay,

To find the same, we will first find the unit price of each,

Unit price = total price / total quantity

Since, 1.8 kg of chicken costs $5.40,

Therefore, 1 kg will cost = 5.40 / 1.8 = $3

Similarly,

If 1.6 kg of meat costs $6.40,

Therefore, 1 kg will cost = 6.40 / 1.6 = $4

Now, to find the cost of 2.4 kg of chicken and 2 kg of meat, we will multiply the unit prices to the required quantities,

Therefore,

2.4 kg of chicken will cost = 2.4 x 3 = $7.2

2 kg of meat will cost = 2 x 4 = $8

In total, she had to pay = 8+7.2 = $15.2

Hence, the amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

Answer:

The number can be expressed in multiple forms

Fraction form [tex]x=\frac{2962}{67}[/tex]  or decimal form  [tex]x=44.21[/tex]

Step-by-step explanation:

Lets break the problem down

"times" is multiplication *

The difference between 2 numbers is subtraction  [tex](x-y)[/tex]

A number plus a number is addition [tex]x+y[/tex]

[tex]68(x-45)=x+-98[/tex]

Lets solve for [tex]x[/tex].

Lets start on the left side.

Distribute 68 to the terms inside the parenthesis.

[tex]68x-3060=x+-98[/tex]

A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign.

[tex]68x-3060=x-98[/tex]

Subtract [tex]x[/tex] from both sides of the equation.

[tex]68x-3060-x=-98[/tex]

Subtract [tex]x[/tex] from [tex]68x[/tex].

[tex]67x-3060=-98[/tex]

Add 3060 to both sides of the equation.

[tex]67x=2962[/tex]

Divide both sides of the equation by 67.

[tex]x=\frac{2962}{67}[/tex] or as a decimal [tex]x=44.21[/tex]

a) The proportion of observations, P(z < -0.67) = 0.2514.

b) The proportion of observations, P(z > -0.67) = 0.7486.

c) The proportion of observations, P(z < 1.46) = 0.9279.

d) The proportion of observations, P(-0.67< z < 1.46) = 0.6765.

A z-table, or standard normal table, helps to reveals what percentage of values fall below a certain z-score in a normal distribution. We have a standard normal table present above .

a) P( z < -0.67 )

Split -0.67 such as (-0.6 + 0.07 ) and look -0.6 in first column and 0.07 in first row then look cross value. So, P( z < -0.67 )

= 0.2514

b) P( z > - 0.67 ) = 1 - P( z < -0.67 )

From part (a ) , P( z < -0.67 ) = 0.2514

So, P( z > - 0.67 ) = 1 - 0.2514 = 0.7486

=> P( z > - 0.67 ) = 0.7486

c ) P( z < 1.46 ) = 1 - P( z < -1.46 )

Using Table, P( z < -1.46 ) is,

=> P( z < -1.46 ) = 0.0721

So, P( z < 1.46 ) = 1 - 0.0721 = 0.9279

=> P( z < 1.46 ) = 0.9279

d) P(-0.67 < z < 1.46 ) = P( z < 1.46) - P( z < -0.67 ) from part( a) , P( z < -0.67 ) = 0.2514

and from par (c) , P( z < 1.46 ) = 0.9279

So, P(-0.67 < z < 1.46 ) = 0.9279 - 0.2514

= 0.6765

=> P(-0.67 < z < 1.46 ) = 0.6765

Hence, all the required proportion are determined.

It can be inferred that as one variable increases, so does the other. Additionally, a change in one variable is likely to be accompanied by a corresponding change in the other.

A significant positive correlation between two variables means that as one variable increases, the other also increases. This implies that when one variable changes, the other is likely to follow suit. For example, if Variable X increases, Variable Y is likely to increase as well. This can be interpreted as a direct relationship between the two variables. Additionally, a significant positive correlation indicates that the two variables have a strong relationship, meaning that as one variable increases or decreases, the other is likely to follow suit. This can be used to help make predictions and draw conclusions about the relationship between the two variables.

The complete question: A significant positive correlation is found between variables x and y. Which one of the following may be safely inferred? a. As x increases, y increases. b. As x increases, y decreases. c. y causes x. d. x causes y.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, A bag containing 12 colored marbles. Dan drew a single marble from the bag 25 times, replacing the marble each time.

He recorded drawing a red marble 9 times.

Thus, the number of red marvels = 12 * 9 /25

the number of red marvels = 4.32 or 4

He recorded drawing a yellow marble 6 times,

Thus, the number of yellow marbles = 12 *6/25

the number of yellow marbles = 2.88 or 3 approx

He recorded drawing a blue marble 4 times,

Thus, the number of blue marbles = 12 *4/25

the number of blue marbles =  1.92 or 2 approx

He recorded drawing and a green marble 6 times.

The linear function that represents the table values is y = 3x + 5.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Using two points from the table, (0,5) and (2,11)

First, we determine the slope m.

Slope m = change in y / change in x

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Plug in the values

Slope m = ( 11 - 5 ) / ( 2 - 0 )

Slope m = 6 / 2

Slope m = 3

Plug the slope m =3 and point (0,5) into the point-slope formula and simplify.

y - y₁ = m( x - x₁ )

y - 5 = 3( x - 0 )

y - 5 = 3x - 0

y - 5 = 3x

Add 5 to both sides

y - 5 + 5 = 3x + 5

y = 3x + 5.

The values of x and y in the parallel lines are 10 and -5 respectively.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, linear angles, alternate interior angles, alternate exterior angles, same side interior angles, vertically opposite angles etc.

Therefore, using same side interior angles,

6x + 2y + 130 = 180

2x - 4y + 140 = 180

Recall same side interior angles are supplementary

Hence,

6x + 2y = 50

2x - 4y  = 40

multiply equation(ii) by 3

6x + 2y = 50

6x - 12y = 120

subtract the equations

14y = - 70

y = -70 / 14

y = -5

Let's find x

6x + 2y = 50

6x = 50 - 2(-5)

6x = 50 + 10

6x = 60

x = 60 / 6

The solution of the initial value problem is y = -3x/(3㏑x - 1)

An initial value problem is a differential equation in which the initial value of the function is given.

Now we have the initial value problem

y' = (xy + y²)/x² , y(1) = 3.

We notice that it is a homogeneous differential equation.

A homogeneous differential equation is a differential equation in which the powers of x and y are the same.

So, we proceed to solve the equation as folows.

Let y = vx.

So,

y/x = v and

dy/dx = xdv/dx + v

We now substitute these into the differential equation, we have that

y' = (xy + y²)/x²

dy/dx = (xy/x² + y²/x²

xdv/dx + v = y/x + (y/x)²

xdv/dx + v = v + v²

xdv/dx = v²

So using the method of separation of variables, we have

dv/v² = dx/x

Thus Integrating both sides, we have

∫dv/v² = ∫dx/x

-v⁻¹ = ㏑x + C

-1/v = ㏑x + C

We now substitute v = y/x into the equation, we have

- 1/y/x = ㏑x + C

-x/y = ㏑x + C

So, making y subject of the formula, we have

y = -x/(㏑x + C)

Since y(1) = 3, we have

3 = -1/(㏑1 + C)

3 = -1/(0 + C)

3 = -1/C

C = -1/3

So, y = -x/(㏑x + (-1/3))

y = -x/(㏑x - 1/3)

y = -x/(3㏑x - 1)/3

y = -3x/(3㏑x - 1)

So, the solution is y = -3x/(3㏑x - 1)

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Figure is shown in image.

Now, By definition of vertically opposite angle,

⇒ (y + 23)° = 63°

Solve for y;

⇒ y + 23 = 63

Subtract 23 both side,

⇒ y + 23 - 23 = 63 - 23

⇒ y = 40

And, By definition of supplementary angles, we get;

⇒ (2x - 17)° + 63° = 180°

Solve for x;

⇒ 2x - 17 + 63 = 180

⇒ 2x + 46 = 180

⇒ 2x + 46 - 46 = 180 - 46
