Answer: The only true statement is:

" A debt of $17 is a larger value than a debt of $20."

Step-by-step explanation:

Let's analyze the options:

A) " 8.01 is a smaller increase in sales then 8.001"

Here you can see the difference:

8.01 - 8.001 = 0.009

The difference is positive, then 8.01 > 8.001.

Then as we are talking of increases in sales, the numbers are positive, then we have that 8.01 is a larger increase in sales than 8.001.

B) "A debt of $17 is a larger value than a debt of $20."

A debt is written as a negative number, then:

A debt of $17 is written as -$17, and a debt of $20 is written as -$20.

Then -$17 is a smaller negative number than -$20

-$17 > -$20

Then this statement is true.

C) " 2/3 bellow zero is lower than 6 bellow zero"

ok, 2/3 bellow zero is: -2/3

6 bellow zero is: -6

-2/3 is larger than -6

-2/3 > -6

then -6 is lower than -2/3, the statement is false.

D) "1/2 of an apple is equivalent to 8/4 apples"

Well, here you can do the quotients:

1/2 = 0.5

8/4 = 2

So these numbers are not equivalents.

Answer:

Quedan 3 libras de azúcar en el costal.

Step-by-step explanation:

Una kilo es aproximadamente dos libras y dos libras y media equivalen a un paquete, para determinar la cantidad remanente de libras de azúcar luego de las ventas se calcula la masa vendida por regla de tres compuesta:

[tex]x = 5\,p \times \frac{2,5\,kg}{1\,p}\times \frac{2\,lb}{1\,kg}[/tex]

[tex]x = 25\,lb[/tex]

Juana vendió 25 libras de azúcar. Entonces, la masa remanente de azúcar en el costal es:

[tex]x = 28\,lb-25\,lb[/tex]

[tex]x = 3\,lb[/tex]

Quedan 3 libras de azúcar en el costal.

The total amount of sugar left in the sack is 3 pounds.

Using the conversion:

1 kg = 2lb

2.5kg =5lb

Amount of sugar left in the sack = Total  - amount sold

Amount of sugar left in the sack = 28lb - 25lb

Amount of sugar left in the sack = 3lb

Answer:

x = 126

Step-by-step explanation:

[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex]

Given

[tex](x-1)^{\frac{2}{3} }[/tex] - 25 = 0 ( add 25 to both sides )

[tex](x-1)^{\frac{2}{3} }[/tex] = 25 ( raise each side to the power of 3 )

(x - 1)² = 25³ = 15625 ( take the square root of both sides )

Answer:

This is the picture answer :)

Step-by-step explanation:

The equation of the line with the given slope and y-intercept is y=12x+2.

Given that, the slope of a line=12 and y-intercept=2.

Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line.

Where, m=slope and b=intercept.

Now, substitute slope=12 and y-intercept=2 in y=mx+b.

That is, y=12x+2

Answer:

See attached graph.

Step-by-step explanation:

This equation is already in slope-intercept form.

This means the term next to the x is the slope, and the constant being added is the y-intercept.

We know that the y-intercept will be 4 because that’s the constant being added. We also know the slope is [tex]\frac{2}{3}[/tex].

A slope of [tex]\frac{2}{3}[/tex] will increase in x by 3, for every increase in y by 2.

Answer:

41/120, 7/20, 43/120, 11/30, 3/8

Step-by-step explanation:

Write the numbers.

1/3 & 2/5

We need a common denominator, but not the least common denominator. Both 3 and 5 are factors of 60, so let's use 60 as the common denominator.

Multiply 1/3 by 20/20:

1/3 = 20/60

Multiply 2/5 by 12/12:

2/5 = 24/60

Let's multiply each fraction again, but this time by 2/2.

1/3 = 40/120

2/5 = 48/120

Now it's easy to find 5 numbers between 40 and 48, so we get:

41/120, 42/120, 43/120, 44/120, 45/120

Some of these fractions can be reduced, so our answer is:

41/120, 7/20, 43/120, 11/30, 3/8

Answer:

Step-by-step explanation:

x - 9/12 + 8/12 = 17/12

x - 1/12 = 17/12

x = 18/12= 3/2 = 1 1/2

Value of x = (4 / 3) which makes the given equation true.

" Variable is defined as the value which changes as per the condition act on it."

According to the question,

Given equation,

x - (3/4) + (2/3) = (17 / 12)

Convert all fraction into like fractions we get,

  x - (3/4) ×(3/3) +(2/3)×(4/4) = (17 /12)

⇒x - (9/12) + (8 /12) = (17 /12)

⇒x - (1/12) = (17 /12)

⇒x = (17/12) +(1/12)

⇒x= (18 /12)

⇒x= (3/2)

Hence, Value of x = (4 / 3) which makes the given equation true.

Answer:

The P-value is 0.0353.

Step-by-step explanation:

We are given the six measurements of a sprinter's reaction time show below;

X = 0.152, 0.154, 0.166, 0.147, 0.161, and 0.159 seconds.

Let [tex]\mu[/tex] = mean sprinter's reaction time

So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \leq[/tex] 0.150 seconds    {means that the mean sprinter's reaction time is at most 0.150 seconds}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 0.150 seconds    {means that the mean sprinter's reaction time is more than 0.150 seconds}

The test statistics that will be used here is One-sample t-test statistics because we don't know about the population standard deviation;

                             T.S.  =    ~  

where, [tex]\bar X[/tex] = sample mean = [tex]\frac{\sum X}{n}[/tex] = [tex]\frac{0.939}{6}[/tex] = 0.1565 seconds

            s = sample standard deviation =  [tex]\sqrt{\frac{\sum (X-\bar X)^{2} }{n-1} }[/tex] = 0.0068 seconds

            n = sample of measurements = 6

So, the test statistics =  [tex]\frac{0.1565-0.150}{\frac{0.0068}{\sqrt{6} } }[/tex]  ~  [tex]t_5[/tex]

                                    =  2.341  

The value of t-test statistics is 2.341.

Now, the P-value of the test statistics is given by the following formula;

P-value = P( > 2.341) = 0.0353.

Answer:

12 arrangments, 2 blue carnations in each arrangement, 3 red carnations in each arrangment.

Step-by-step explanation:

We can find the gcd of 24 and 36, getting 12.

Therefore, there should be 12 total arrangements.

There are 24 blue carnations:

24 / 12 = 2 blue carnations in each arrangement.

There are 36 red carnations:

36 / 12 = 3 red carnations in each arrangment.

Answer:

The number of cuboids that will be needed to form a cube is 2625 cuboids

Step-by-step explanation:

To form a cube, we have;

The length = The height = The depth

The dimensions of the given cuboid = Length = 75 cm, the width = 35 cm, the depth = 21 cm.

Therefore;

The lowest common multiple of 75, 35, and 21, for the cuboid is given as follows;

75 = 5 × 5 × 3

35 = 5 × 7

21 = 3 × 7

Therefore, multiplying 75 by 7, we get;

75 × 7 = 525

Since 7, 5 and 3 are factors of 525, 35 and 21, can also be factors as we check;

525/35 = 15

525/21 = 25

Therefore, the cube will be;

The length of the cube will consist of 7 pieces of the cuboid, arranged with the side 75 cm facing the front

The depth of the cuboid will be 15 cuboids with the side 35 cm facing the sides

The height of the cuboid will be 25 cuboids with the side 21 cm high

The total number of cuboids is therefore;

7 × 15 × 25 = 2625 cuboids

The number of cuboids that will be needed to form a cube = 2625 cuboids.
