Answer: (97.63, 99.77)

Step-by-step explanation:

Given the data:

99.6 99.7 97.9 98.6 97.7

Using calculator, we can obtain the mean and standard deviation of the sample data:

Mean(m) = 98.7

Standard deviation = 0.93

Sample size (n) = 5

Using the relation to find confidence interval :

Mean ± Zcrit * (s/√n)

Zcrit at 99% = 2.576

98.7 ± 2.576 * (0.93 / √5)

Lower limit : 98.7 - (2.576 * 0.4159086) = 97.6286194464 = 97.63 ( 1 decimal place)

Upper limit : 98.7 + (2.576 * 0.4159086) = 99.7713805536 = 99.77 ( 1 decimal place)

(97.6, 99.8)

Answer:

4 5/12 %

4.41667 %

Dividend = 13 1/4 %

Divisor = 3 hours

Quotient = 4 5/12 %

Step-by-step explanation:

Given that :

Percentage charge left = 23 1/4%

Percentage to be used hourly such that atleast 10% is left in other to make a call 4 hours from now

Hence,

Usable charge = Percentage left - target percentage

23 1/4 % - 10% = 13 1/4 %

Number hours of usable charge = 4 - 1= 3 hours

13 1/4 % ÷ 3

53/4 % ÷ 3

4.41666 % per hour

Or

53/4 * 1/3 = 53/12 =4 5/12 %

Dividend = 13 1/4 %

Divisor = 3 hours

Quotient = 4 5/12 %

Answer:

a. Domain -4 ≤ x ≤ 3, Range 0 ≤ y ≤ 5

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, we see that our x-values span from -4 to 3. Since both dots are closed dots, they are inclusive in the domain:

[-4, 3] or -4 ≤ x ≤ 3

According to the graph, we see that our y-values span from 0 to 5. Since both dots are closed dots, they are inclusive in the range:

[0, 5] or 0 ≤ y ≤ 5

Answer:

The correct answer to this is 200 and 34.90%

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 3000 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 3000, so we can write it down as 100%=3000.

4. We know, that x% equals 1046 of the output value, so we can write it down as x%=1046.

5. Now we have two simple equations:

1) 100%=3000

2) x%=1046

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=3000/1046

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1046 is what percent of 3000

100%/x%=3000/1046

(100/x)*x=(3000/1046)*x       - we multiply both sides of the equation by x

100=2.868068833652*x       - we divide both sides of the equation by (2.868068833652) to get x

100/2.868068833652=x

34.866666666667=x

x=34.866666666667

now we have:

1046 is 34.866666666667% of 3000

Sample proportion = 0.65

And, The percentage of the sample proportion = 65%

The percentage of the readers surveyed do not use e-readers = 35%

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given sample size is,

'n' =3000

Of the 3,000 readers surveyed, 1,954 said they read books on an e-reader.

Hence, The probability that The readers surveyed use e-readers sample proportion is,

p = 1954 / 3000

p = 0.6513

Hence, The percentage of the sample proportion is, 65%

And, The readers surveyed do not use e-readers is,

q = 1 - p

q = 1 - 0.651

q = 0.349

Thus, Sample proportion = 0.65

And, The percentage of the sample proportion = 65%

The percentage of the readers surveyed do not use e-readers = 35%

GCF of 27 and 45 is 9

Answer: 9 (3+5)

Step-by-step explanation:

The GFCF of these two numbers is 9 as they can both be divided by it

Distributive property form is when you place the GFC outside parenthesis so that the equation can be multiplied in order to show the original equation and dividing the numbers by the GCF so that it does not give you a larger number than what you started with

27/9=3 + 45/9=5

So, keeping this in mind the distributive property form would be 9(3+5)

Answer 9(3+5)

Answer:

Rate of increase of radius = 0.0064 ft/sec

Rate of increase of surface area = 1.61 [tex]ft^2/sec[/tex]

Step-by-step explanation:

Given that:

Rate of change of volume of a spherical balloon = 8 cubic feet per minute

[tex]\dfrac{dV}{dt} = 8 ft^3/min[/tex]

Radius, [tex]r[/tex] = 10 feet

To find:

The rate of change of radius at this moment and rate of change of surface area at this moment?

Solution:

First of all, let us have a look at the formula:

[tex]1.\ V = \dfrac{4}{3}\pi r^3\\2.\ A =4\pi r^2[/tex]

Now, differentiating the volume and area, we get:

[tex]\dfrac{dV}{dt} = \dfrac{4}{3}\times 3 \pi r^2 \dfrac{dr}{dt}\\\Rightarrow \dfrac{dV}{dt} = 4 \pi r^2 \dfrac{dr}{dt}[/tex]

[tex]\dfrac{dA}{dt} = 4\pi \times 2 r \dfrac{dr}{dt}\\\Rightarrow \dfrac{dA}{dt} = 8\pi r \dfrac{dr}{dt}[/tex]

[tex]\dfrac{dV}{dt} = 8 = 4\pi r^2 \dfrac{dr}{dt}\\\Rightarrow 8 = 4\times 3.14 \times 10^2 \dfrac{dr}{dt}\\\Rightarrow 2 = 3.14 \times 10^2 \dfrac{dr}{dt}\\\Rightarrow \dfrac{dr}{dt} = 0.0064\ ft/sec[/tex]

[tex]\dfrac{dA}{dt} = 8\times \pi \times r \dfrac{dr}{dt}\\\Rightarrow \dfrac{dA}{dt} = 8\times 3.14 \times 10 \times 0.0064\\\Rightarrow \dfrac{dA}{dt} = \bold{1.61 \ ft^2/sec}[/tex]

Answer:

Step-by-step explanation:

14%

If the Algerian government wishes to raise $9 billion in tax revenue, income tax rate should be 14%.

Income tax is a form of tax levied on the income of labor by the government. Income tax reduces the income earned by labor.

In order to determine the income tax rate, take the following steps:

Determine the total income of the workforce: 9,416,534 x $6,844 = 64.45 billion

Now, divide the desired tax revenue by the total income: (9 billion / 64.45 billion)  x 100 = 14%
