Need the answer for x and y

Answer:

c. We are 92% confident that the mean height of the entire business is in this interval.

f. The 85% confidence interval is a subset of the 92% confidence interval.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

Margin of error:

The larger the confidence interval, the larger the margin of error. That means that for example, an 85% confidence interval is a subset of the 92% confidence interval.

In this question:

92% confidence interval -> We are 92% sure that the population mean is in this interval.

The 85% confidence interval is a subset of the 92% confidence interval.

So options c and f.

Answer:

[tex]\dfrac{1}{24}[/tex]

Step-by-step explanation:

We need to find the value of 1/4÷6.

It can be done as follows :

[tex]\dfrac{\dfrac{1}{4}}{6}[/tex]

We know that, [tex]\dfrac{\dfrac{1}{x}}{y}=\dfrac{1}{xy}[/tex]

We have, x = 4 and y = 6

So,

[tex]\dfrac{\dfrac{1}{4}}{6}=\dfrac{1}{4\times 6}\\\\=\dfrac{1}{24}[/tex]

So, the final answer is equal to [tex]\dfrac{1}{24}[/tex].

Answer: 60 - 10

Step-by-step explanation:

There are 5 commercial breaks with each of the breaks lasting 2 minutes.

Commercial breaks in total therefore last:

= 5 * 2

= 10 minutes.

The program is a 60 minute program so to find the amount of time the program lasts without the commercials, the expression is:

= 60 - 10

It lasts 50 minutes without commercials.

Step-by-step explanation:

The relative change is solved as percentages and the absolute change is also solved

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the initial value be represented as A = 13.60 at time t = 0

Now , when the value is changed to 17.00

The absolute change = 17.00 - 13.60 = 3.40

The relative change = 3.40 / 13.60 = 0.25 = 25 %

Now , the percentage = 25 %

And , when the value is changed to 21.25

The absolute change = 21.25 - 17.00 = 4.25

The relative change = 4.25 / 17.00 = 0.25 = 25 %

And , when the value is changed to 26.56

The absolute change = 26.56 - 21.25 = 5.31

The relative change = 5.31 / 21.25 = 0.25 = 25 %

Now , the percentage = 25 %

And , when the value is changed to 33.20

The absolute change = 33.20 - 26.56 = 6.64

The relative change = 6.64 / 26.56 = 0.25 = 25 %

And , when the value is changed to 41.50

The absolute change = 41.50 - 33.20 = 4.25

The relative change = 8.3 / 33.20 = 0.25 = 25 %

Now , the percentage = 25 %

Hence , the relative change is given by the equation A = 25 %

Some calculators can compute the value for you directly.

Answer:

1. No

2. No

3. No

4. Yes

Step-by-step explanation:

Binomial approximation to normal.

The binomial probability distribution has parameters n, p and q.

If

[tex]np \geq 5[/tex] and [tex]nq \geq 5[/tex], you can use the normal approximation.

1. n = 24, p = 0.85, q = 0.15

[tex]np = 24*0.85 = 20.4 > 5[/tex]

[tex]nq = 24*0.15 = 3.6 < 5[/tex]

So no.

2. n = 15, p = 0.70, q = 0.30

[tex]np = 15*0.7 = 10.5 > 5[/tex]

[tex]nq = 15*0.3 = 4.5 < 5[/tex]

So no.

3. n = 18, p = 0.90, q = 0.10

[tex]np = 18*0.9 = 16.2 > 5[/tex]

[tex]nq = 18*0.1 = 1.8 < 5[/tex]

No

4. n = 20, p = 0.65, q = 0.35

[tex]np = 20*0.65 = 13 > 5[/tex]

[tex]nq = 20*0.35 = 7 > 5[/tex]

The Volume of dirt required for the Margo's garden which is made of 2 rectangular prisms is, 107 cubic feet, So option D is correct

In mathematics, Space occupied by three dimensional objects is called Volume. Basically it is a space within closed region of  every three dimensional objects.

In given problem, we have two rectangular prisms

One has sides (1 feet, 3  feet, 3  feet)

Another one has sides (2 feet, 7 feet, 7 feet)

Volume of a rectangular prism  = Length×Height×Width

Volume of a rectangular prism 1  = 3×1×3 = 9

Volume of a rectangular prism 2  = 7×2×7 = 98

Total Volume = 107

Hence, Total dirt required  107 cubic feet

Answer:

2x² - 2x - 12 ÷ (x+2)

= 2x - 6

D. 2x-6 with no remainder

The quotient when (x + 2) is divided into the polynomial 2x² - 2x - 12 is, (2x - 6) with no remainder.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

To find the quotient when (x + 2) is divided into the polynomial

2x² - 2x - 12.

Now,

The polynomial is,

⇒ 2x² - 2x - 12

⇒ 2 (x² - x - 6)

⇒ 2 (x² - 3x + 2x - 6)

⇒ 2 [ x (x - 3) + 2(x - 3) ]

⇒ 2 [ (x + 2) (x - 3) ]

Hence, We can divide polynomial by (x + 2) as;

⇒ 2 [ (x + 2) (x - 3) ] ÷ (x + 2)

⇒ 2 (x - 3)

⇒ 2x - 6

Therefore, the quotient when (x + 2) is divided into the polynomial

2x² - 2x - 12 is, (2x - 6) with no remainder.
