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:

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

Therefore, the equation of the line is y=12x+2.

Answer as a fraction = 9/4

Answer in decimal form = 2.25

================================================

Explanation:

1/4 = 4/16 after multiplying top and bottom by 4

We have some number x such that

(4/16)x = 9/16

we can multiply both sides by 16 to clear out the fractions, getting 4x = 9

Then we divide both sides by 4 to get x = 9/4 = 2.25

Answer:

[tex]Cost = \$120 * 1 - \$120 * 0.25[/tex]

Step-by-step explanation:

Given

[tex]Cost = \$120 - 0.25(\$120)[/tex]

Required

Solve using distributive property

[tex]Cost = \$120 - 0.25(\$120)[/tex]

[tex]\$120[/tex] can be rewritten as [tex]1(\$120)[/tex]

So:

[tex]Cost = 1(\$120) - 0.25(\$120)[/tex]

Factorize:

[tex]Cost = \$120(1 - 0.25)[/tex]

Now, we can apply distributive property on the expression;

[tex]Cost = \$120 * 1 - \$120 * 0.25[/tex]

Hence, the above is an equivalent expression.

Solving further, we have

[tex]Cost = \$120 - \$30[/tex]

[tex]Cost = \$90[/tex]

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:

20 units

Step-by-step explanation:

Initial particle concentration = 80 units

Particles removed each hour = 50% of the remaining particles

To find:

Particle concentration after 2 hours = ?

Solution:

Particles removed in 1 hour = 50% of remaining particles

i.e. Particles removed in 1 hour = 50% of initial concentration

Particles removed in 1 hour = 50% of 80 = 40

Particles removed in next 1 hour = 50% of remaining particles

i.e. Particles removed in next 1 hour = 50% of concentration after 1 hour

Particles removed in next 1 hour = 50% of 40 = 20

Total particles concentration removed in 2 hours = 40 + 20 = 60 units

Therefore, particle concentration after 2 hours = Initial concentration - Total particle concentration removed in 2 hours

= 80 - 60 = 20 units

3.4568

Step-by-step explanation:

We need to dive to the ten-thousandths place to get numbers between the two.

=======================================================

Explanation:

S = sum of the salaries of the first 15 employees

S/15 = mean of the 15 salaries

S/15 = 2930

S = 15*2930

S = 43950

The 15 workers salaries add to 43950.

If we add on a new 16th salary of 3138, then the sum bumps up to

S+3138 = 43950+3138 = 47088

This is the sum of the 16 workers salaries. Divide this over 16 to get the new average

47088/16 = 2943

The new mean is 2943

It is larger than the old mean because the 16th salary is larger than the mean. Effectively this new salary pulls on the mean to make it larger. With very distant outliers, the mean is pulled a lot which often causes problems. So this is why the median is a better measure of center in those situations. Either that measure of center, or using a trimmed mean works as well.

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.

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:

Step-by-step explanation:

2(x-(3/2))^2+10-9/2=0

2(x-(3/2))^2+(20-9)/2=0

2(x-(3/2))^2+11/2=0

2(x-(3/2))^2=-11/2

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:

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:
