From the statement, we know that:

• a jar contains 100 tickets for a drawing,

• among those tickets are 7 winning tickets.

We must find the odds in favour of winning.

The odds in favour of winning are:

Odds in favour = Number of successes : Number of failures

In this case, we have:

• Number of successes = 7,

• Number of failures = 100 - 7 = 93.

So we have:

7:93

The probability of selecting or having a marble to be either a blue marble or a stone marble is 0.8076.

Given, a bag contains 6 blue glass marbles, 5 yellow glass marbles,

12 blue stone marbles and 3 yellow stone marbles.

Probability of selecting a marble and having that marble to be either blue marble or a stone marble = ?

we know that,

Glass marbles:

n(B) = 6 and n(Y)= 5

Stone marbles:

n(B) = 12 and n(Y) = 3

Probability = Number of favorable outcomes/Total number of outcomes.

Probability of selecting a marble and having that marble to be either blue marble or a stone marble:

total number of blue marbles = 18

total number of stone marbles = 15

total number of marbles in the bag = 26

⇒ 18+15-12/26

⇒ 33-12/26

⇒ 21/26

= 0.8076

Hence the probability of selecting a marble and having that marble be either a blue marble or a stone marble is 0.8076.

The solution to the system of equations using Cramer's rule is given by the image at the end of the answer.

The solution of a system of equations using Cramer's rule is based on the use of determinants of matrices.

In the context of this problem, the system is:

The matrix for the system is:

M =

[1 2]

[-3 - 2]

The determinant of the matrix M of the system is given as follows:

|M| = -2 + 6 = 4.

(using the standard procedure to obtain the determinant of a 2 x 2 matrix).

To find the matrix for x, the x-coefficients are replaced by the right-side coefficients, that is, the results of the operations, hence:

Mx =

[8 2]

[12 - 2]

Then the determinant is:

|Mx| = 8(-2) - 2(12) = -16 - 24 = -40.

The solution for x is:

x = -40/4 = -10.

To find the matrix for y, the y-coefficients are replaced by the right-side coefficients, that is, the results of the operations, hence:

My =

[1 8]

[-3  12]

The determinant is:

|My| =  12 - (-3)(8) = 12 + 24 = 36.

Hence the solution is:

y = 36/4 = 9.

The statement which is true is Option(D) The output value of the function is 8 when the input value is -2.

An expression, rule, or regulation that establishes a relationship between one variable (the independent variable) and another variable (the dependent variable) is referred to as a function in mathematics.

Given function:

H(x) = -x + 6

In Option A, the input value is -2 so the output of the function will be,

H(x) = -x + 6 = -(-2) +6 = 2+ 6 = 8 ,which is not equal to the given output value 4.

Hence, the statement is false.

Similarly in Option B and C, the input values are 1 and x.

H(x) = -x + 6 = -1 +6 = 5 ≠ 7

H(x) = -x + 6 ≠ 6

The given output values are not equal to the output values calculated.

So both statements are false.

In Option D the input value is -2 and the output value is 8 which is a correct statement as calculated in Option A.

The experimental probability of rolling such that the number is more than 3 is 0.44.

The proportion of outcomes where a specific event occurs in all trials, not in a hypothetical sample space but in a real experiment, is known as the empirical probability, relative frequency, or experimental probability of an event.

When a dies is rolled 200 times, the results are:

Frequency     Outcome

     1                     32

     2                    36

     3                    44

     4                    20

     5                    30

     6                    38

Therefore,

The experimental probability that a number is more than 3 after rolling will be:

= The sum of outcome above 3 / total outcome

= ( 20 + 30 + 38 ) / ( 32 + 36 + 44 + 20 + 30 + 38 )

= 88/ 200

= 0.44

Hence, the probability that the number is more than 3 is 0.44.

Answer:

105

Step-by-step explanation:

Let x, y and z be the 3 numbers in the order first, second and third

x + y + z = 180

Second number y is 3 times the smallest number and third number z is 7 times the smallest number. So smallest number has to be x

so y = 4x

z = 7x

x + y + z = x + 4x + 7x = 180

12x = 180

x = 15

Largest number = 7 x 15 = 105

The shoes cost $14.03 at Walmart.

Explanation

The markup, the selling price and the cost price are all related through the relation

For this question,

Markup percent = 65%

Selling Price = x = ?

Cost Price = $8.50

x - 8.5 = (0.65) (8.5)

x - 8.5 = 5.525

x = 8.5 + 5.525

x = $14.025

x = $14.03

A function to represent the relation is  f = q × p, the quantity that maximizes value could only be when q = p, therefore p = 200 so, q = 200 too according to demand function q = 1200 - 5p.

In mathematics, the relationship between demand and its factors is represented by a demand function. The function demonstrates how elements like a product's own price, buyer income, and the cost of related products affect demand for a given good (substitutes and complements).

We can deduce from the equation how they influence a product's demand, whether positively or negatively, and how much.

A function for generated revenue is simply f = q × p

where f is the generated revenue and

q is the quantity and

p is the price.

The quantity that maximizes value could only be when q = p

Lets substitute the value of q in q = 1200 - 5p,

q + 5p = 1200

But q = p so

p + 5p = 1200

6p = 1200

p = 1200/6

p = 200

So when price is 200 the revenue will be maximized as the quantity is equal to as price.

Angles are the measure of space when two or more lines intersect.

The figure represents the given parameter

On the figure, we have the following angle measures

AED = 2x

BEF = 4x

EBC = 6x

Using the above as a guide, we have the following angle measures

BAE = AED = 2x ---- Corresponding angles

BEA = 180 - BEF ---- Angle on a straight line

BEA = 180 - 4x

ABE = 180 - EBC ---- Angle on a straight line

ABE = 180 - 6x

The sum of angles in a triangle is 180

So, we have

BAE  + BEA + ABE  = 180

This gives

2x + 180 - 4x + 180 - 6x = 180

-8x = -180

Answer:

y = -800x + 294000

286,000

Step-by-step explanation:

To write the equation, you need the slope and the y-intercept.  

The slope is -800

You find the slope by the change in y over the change in x

[tex]\frac{288400 - 294000}{7 - 0}[/tex] = [tex]\frac{15600}{7}[/tex] = -800

Now we will find the y -intercept.  I will use the slope and the point (0, 294,000) to find this.  I could have used the other point given. They will both work.

slope (m) = -800

x = 0

y = 294000

y = mx + b

294000 = -800(0) = b

294000 = b

The equation is

y = mx + b

y = -800x + 294000

2014

y = -800x + 294000

y = -800(10) + 294000

y =-8000 + 294000

y  = 286,000

The range of the function, y = 16x, is 60, where y is 960.

The range of the function, y = 16x, are the possible values that x can assume to meet the value of y.

Usually, the range of a function is the output value.

Since the value of y = 960, the range of the function will be 60 (960/16).

The capacity of the dispenser = 960 ounces

The capacity of the juice containers = 16 ounces

The function that models the situation is y = 16x

Where y = 960

x = 60 (960/16)
