The length of a rectangle is twice its width. The perimeter is eighty-four inches. Find the length and width. The length is inches. The width is inches.​

Answer:

[tex]N_c \approx 5.0[/tex]

Step-by-step explanation:

From the question we are told that:

Waiting time for a container of the wheels during production [tex]T_w=0.25day[/tex]

Average processing time is [tex]T_a=0.15 day per container[/tex]

Wheel per container [tex]N_w=200[/tex]

Total wheel per day [tex]D=2000[/tex]

Policy variable of [tex]X=5%[/tex]  

Generally the equation for Total number of container [tex]N_c[/tex] is mathematically given by

[tex]N_c=DT(\frac{1+X}{N_w} )[/tex]

Where

Total time [tex]T=T_w+T_a[/tex]

[tex]T=0.15+0.25[/tex]

Therefore

[tex]N_c=DT(\frac{1+X}{N_w} )[/tex]

[tex]N_c=2000*0.40(\frac{1+0.5}{200} )[/tex]

[tex]N_c=(\frac{840}{200} )[/tex]

[tex]N_c=4.2[/tex]

[tex]N_c \approx 5.0[/tex]

Therefore the number of Kanban containers needed for the wheels is

[tex]N_c \approx 5.0[/tex]

Answer: 144

Step-by-step explanation:

I'm assuming that the "x" in this statement is a multiplication symbol.

Multiplying any number by 1/2 or 0.5 is the same thing as dividing it by 2.

Therfore the answer is 288/2 which is 144.

Answer:

Option D

Step-by-step explanation :

→ Minus 10n and 48 from both sides

2n² - 10n - 48 = 0

→ Divide everything by 2

n² - 5n - 24 = 0

→ Factorise

( n + 3 ) ( n - 8 )

Answer:

D

Step-by-step explanation:

2n²-10n-48=0

n²-5n-24=0

(n-8)(n+3)

n-8=0

Answer:

  y = 11.2 in

Step-by-step explanation:

The product of segment lengths to the near and far intersection points of the secant with the circle are the same for all secants from the same external point. Here, there are three, so we have the relations ...

  9×9 = 5(5+y) = x(x+19)

Then the value of y can be found as ...

  81/5 = 5+y

  16.2 -5 = y = 11.2

__

The value of x is a little trickier, as a quadratic is involved.

  81 = x² +19x

  81 + 90.25 = x² +19x +90.25 . . . . complete the square

  171.25 = (x +9.5)²

  x = √171.25 - 9.5 ≈ 3.58625...

__

Additional comment

For the purpose here, the tangent can be considered to be a degenerate case of a secant in which the two points of intersection with the circle are the same point. For the purpose of this calculation, the length of the tangent is squared. (The distance to the points of intersection is the same.)

I find it easier to remember one rule, rather than a separate rule for tangents. With some imagination, the same rule can be applied when the "secants" meet inside the circle. In that case, they are called "chords".

We have shown the value for x because we suspect some versions of this question may ask for x instead of y. (Rounding may be required in that case.)

Answer:

2/10 or 1/5 gold, 3/10 blue and 5/10 or 2/5 white

Step-by-step explanation:

2+3+5=10

since you do this 5 times and get 5 marbles it can be:

2/10 or 1/5 gold, 3/10 blue and 5/10 or 2/5 white

The probability of choosing 1 gold marble, 1 blue marble and 3 white marbles is 2/5

Probability is the likelihood or chance that an event will occur.

If there are 2 gold marbles, 3 blue marbles and 5 white marble in the bowl, the total number of marbles will be 10 marbles.

Pr(1 gold marble) = 2/10 = 1/5

Pr(1 blue marble) = 3/10

Pr(3 white marble) = [tex]\frac{3}{5C_3} = \frac{3}{10}[/tex]

Add all the probability;

Pr(hoosing 1 gold marble, 1 blue marble and 3 white marbles) = 1/5 +3/10 + 3/10 = 8/10 = 2/5

Hence the probability of choosing 1 gold marble, 1 blue marble and 3 white marbles is 2/5

[tex]A=\frac{215*x}{2}-x^2)[/tex]

Step-by-step explanation:

From the question we are told that:

Total length of building side [tex]x=25feet[/tex]

Perimeter of  fence in [tex]P=190feet[/tex]

Generally the perimeter of the display area is given as mathematically given by

[tex]2L+2B=P+x\\2L+2B=190+25[/tex]

Therefore

[tex]2L+2B=215[/tex]

[tex]L+B=\frac{215}{2}[/tex]

[tex]B=\frac{215}{2}-L[/tex]

Generally the Area of the display area A is given as mathematically given by

[tex]Area A=L*B[/tex]

[tex]Area A=L*(\frac{215}{2}-L)[/tex]

Answer:

$900

Step-by-step explanation:

The formula for simple interest is I = PRT where I is the interest earned, P is the principal/amount deposited or borrowed, R = rate as a decimal, and T = time in years

I = PRT

I = (500)(0.04)(20)

I = 400

Add the interest to the principal, and she will have $900 in 20 years.

Answer:

The recommended sample size is 1,698

Step-by-step explanation:

The given standard deviation in milk consumption per capita across the U.S., σ = 4 ounces

The required confidence level = 95%

The margin of error, e = ± 0.5

When the precision is doubled, we have the new margin of error = ±0.5/2 = ±0.25

The standard score at 99% confidence level, z = 2.576

The sample size formula is given as follows;

[tex]S = \dfrac{Z^2 \times P \times Q}{E^2}[/tex]

Where;

P × Q = The variance = σ²

∴ P × Q = 4² = 16

The sample size becomes;

S = 2.576² × 16/(0.25²) = 1,698.758656

We round down to get the recommended sample size, S = 1,698

Answer:

T₂ = 1.2 s

Step-by-step explanation:

The time period of a simple pendulum is given by :

[tex]T=2\pi \sqrt{\dfrac{L}{g}}[/tex]

Where

L is length of the pendulum

g is acceleration due to gravity

We have,

T₁ = 1.4 s, L₁ = 0.49 m, L₂ = 0.36 m, T₂= ?

[tex]\dfrac{T_1}{T_2}=\sqrt{\dfrac{L_1}{L_2}} \\\\T_2=\dfrac{T_1}{\sqrt{\dfrac{L_1}{L_2}}}\\\\T_2=\dfrac{1.4}{\sqrt{\dfrac{0.49}{0.36}}}\\\\T_2=1.2\ s[/tex]

So, the new time period is equal to 1.2 seconds.

Answer:

456.9

Step-by-step explanation:

Answer:

Ha: μ < 24

The test statistic is z = -1.75.

The pvalue of the test is 0.0401 > 0.02, which means that we do not reject the null hypothesis, as there is insufficient evidence.

Step-by-step explanation:

A recent survey reported that small businesses spend 24 hours a week marketing their business.

This means that the null hypothesis is:

[tex]H_0: \mu = 24[/tex]

A local chamber of commerce claims that small businesses in their area are not growing because these businesses are spending less than 24 hours a week on marketing.

This means that the alternate hypothesis is:

[tex]H_a: \mu < 24[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

24 is tested at the null hypothesis:

This means that [tex]\mu = 24[/tex]

The chamber conducts a survey of 93 small businesses within their state and finds that the average amount of time spent on marketing is 23.0 hours a week.

This means that [tex]n = 93, X = 23[/tex]

The population standard deviation is 5.5 hours

This means that [tex]\sigma = 5.5[/tex]

Value of the test-statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{23 - 24}{\frac{5.5}{\sqrt{93}}}[/tex]

[tex]z = -1.75[/tex]

The test statistic is z = -1.75.

Do we reject the null hypothesis? Is there sufficient or insufficient evidence?

The pvalue of the test is the probability of finding a sample mean below 23, which is the pvalue of z = -1.75.

Looking at the z table, z = -1.75 has a pvalue of 0.0401

The pvalue of the test is 0.0401 > 0.02, which means that we do not reject the null hypothesis, as there is insufficient evidence.
