A counterexample showing the conclusion 'All the marbles in the bag are black' as false.

A counterexample is a scenario where the premises are true but the conclusion is false, demonstrating the invalidity of an argument. In this case, to prove invalidity, a counterexample could be a situation where there is at least one marble in the bag that is not black. For instance, if there are three black marbles and one red marble inside the bag, the selection of three black marbles is still possible, but the conclusion that all marbles are black is false.

5 x 2 x (-4) + 6 divided by 2

Answers

There is a certain order that we follow in doing any mathematical operation:
First we get rid of any operation within brackets, then we do multiplication and divisions and finally we do additions and subtractions.

We need to evaluate: 5x2x(-4) + 6:
So since we have no operations within brackets, then we will do the multiplications first (in their order) then the addition:
5x2x(-4)+6 = 10x(-4)+6 = -40+6 = -34

Now, we need to divide -34 by 2:
-34/2 = -17

The answer is: -17

Solve for x.

−32>−5+9x

Enter your answer, as an inequality, in the box

Answers

The solution to the inequality -32 > -5 + 9x is x > -3.

To solve the inequality -32 > -5 + 9x, we'll isolate the variable x by first getting rid of the constant term (-5) on the right side.

1. Add 5 to both sides:

-32 + 5 > 9x

-27 > 9x

2. Divide both sides by 9 to solve for x:

-27/9 > x

-3 > x

Therefore, x is greater than -3. In interval notation, this can be written as (-∞, -3). In inequality notation, it's expressed as x > -3.

We started by isolating the variable x by adding 5 to both sides, then divided by 9 to solve for x. Remember, when dividing or multiplying by a negative number, the direction of the inequality sign flips. Thus, the final solution is x > -3.

During a sale at a bookstore, a customer buys one book at full price. The customer is given a 25 percent discount on a second book of equal or less value. If George buys two books that value full prices of $17 and $8, by what percent is the total cost of the two books reduced during the sale?

Answers

Amount paid for the first book is $17.

Amount paid for the second book is 0.75 x 8 = $6

Total amount paid = $17 + $6 = $23

Total full cost of the two books = $17 + $8 = $25

Amount of discount = $25 - $23 = $2

% reduction = [tex] \frac{2}{25} \times100\%=8\%[/tex]

Therefore, the percent of the total cost of the two books reduced during the sale is 8%

8% First, determine what book the discount is applied to. That will be the lower priced book, so the customer saves 25% of the cost of $8, giving 25% * $8 = 0.25 * $8 = $2 So there's a total savings of $2. Now determine what the total price of purchasing both books without the discount. That would be $17 + $8 = $25 And finally, determine what percent of $25 that $2 is, so $2 / $25 = 0.08 = 8%

When the smaller of two consecutive integers is added to three three times the larger, the result is 23. find the integers?

Answers

consecutive integers are numbers in order, 1,2,3,4,5,6,....
if you make x the smaller number the next number will be (x+1).
x +3(x+1) = 23
x +3x +3 = 23
5x = 23 - 3
5x = 20
x = 20/5
x = 4

the smaller integer is 4 then the next is 5

The value of the integers can be obtained by solving the equation as 5 and 6 respectively.

What is a linear equation?

A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.

It can be represented as a straight line on a graph.

Suppose the smaller integer be x.

Then, the larger one is x + 1.

As per the question, the following equation can be formed as,

x + 3(x + 1) = 23

⇒ 4x + 3 = 23

⇒ x = 5

Thus, the larger integer is 5 + 1 = 6.

Hence, the integers are obtained as 5 and 6 respectively.

A box measures 2 cm x 0.09 m x 20 mm. what is its volume in cubic centimeters?

Answers

Final answer:

To find the volume of the box, convert all dimensions to centimeters and then use the formula length x width x height. The volume is 36 cm³.

Explanation:

To calculate the volume of a rectangular box with dimensions in different units, we must first convert all dimensions to the same unit of measure. In this case, we will convert meters and millimeters to centimeters:

0.09 m = 0.09 * 100 cm = 9 cm

20 mm = 20 / 10 cm = 2 cm

Now we can calculate the volume using the formula for the volume of a rectangular box, which is length × width × height:

Volume = 2 cm × 9 cm × 2 cm = 36 cm³

how do you put 2.303,2.3,2.33 and 2.03 from least to greatest

Answers

you add extra zeroes until all numbers have the same quantity. in this case, 2.303 has three numbers after the decimal, so the other three number need it too. 2.300, 2.330, and 2.030. now that you have all of them looking the same now, you can tell which is least and work from there: 2.030 is the least, then 2.300, 2.303 then 2.330 is the largest.

The number can be arranged from least to greatest as 2.03<2.3<2.303<2.33.

What are decimal Numbers?

A decimal is a number with a whole and a fractional portion. Decimal numbers are between integers and indicate numerical value for a whole plus some fraction of a whole. In fraction form, we may say there is one and one-half pizzas. This is represented in decimal form as 1.5 pizzas.

Let's write the numbers to the third decimal point. Therefore, we can write the numbers as,

2.303 = 2.3032.3 = 2.3002.33 = 2.3302.03 = 2.030

Now, the numbers can be arranged as,

2.030 < 2.300 < 2.303 < 2.330

2.03 < 2.3 < 2.303 < 2.33

Hence, the number can be arranged from least to greatest as 2.03<2.3<2.303<2.33.

TheValue of a stock begins at $0.05/and increase by 0.01 each month write an equation representing the value of the stock v in any months m

Answers

Because you start with $0.05, you're going to add that to whatever 0.01 is equal to after the amount of months

the equation I got was: v=0.05+(0.01m)

The linear equation can be represented as a straight line on a graph. The equation for the given case is v = 0.05 + 0.01m.

What is a Linear equation?

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

Given that,

The value of stock at the beginning is $0.05,

And, its rate of increase for each month is 0.01.

Suppose the value of stock be v and the month be m,

Then, the increment in its value for any month m is $0.01m.

Now, the equation for the value of stock v at any month m can be written by summing its initial value to its increment value obtained for each month as,

v = 0.05 + 0.01m.

Hence, the equation representing the value of the stock v in any months m is given as v = 0.05 + 0.01m.

Suppose that there is a positive correlation between the variables k and I. If l is 75when k is 7, which of these is most likely to be the value of l when k is 14.

Answers

positive correlation varies jointly

I = ck
75 = c(7)
75/7 = c
10.71 = c

I = (10.71)k
I = (10.71)(14)
I = 150

Answer:

l = 150

Step-by-step explanation:

The numbers k and have a positive correlation, to know the correlation between these two variables we have to use the values they give us:

When l = 75 the k = 7

The correlation between the two numbers is division. So this can be written as:

correlation: I = 75/7 k

So if we substitute k=14

l = 75/7 * 14

l = 150

We can also get this number by rule of three:

75/7 = x/14

75/7 *14 = l

1050/7 = l

150 = l
