A friend has offered to play a gambling game with you that involves flipping a coin that she has provided. You want to test the coin in advance for fairness before agreeing to gamble. Your friend is willing to let you flip it 50 times to determine if the probability of getting heads is actually 0.50, as it should be if the coin is fair. Is it necessary to check the 10% condition in this case

Answers

Answer:

The 10% condition would not apply here

Explanation:

The 10% condition is the recommended size of sample from the population to get a non biased result. The 10% condition requires that the sample be not more than 10% of the population.

Tossing a coin is an example of a Bernoulli trial. A Bernoulli trial is one that has two possible outcomes, this face of the coin or the other face of the coin. The 10% condition does not apply to Bernoulli trials that are independent events.

Therefore the 10% condition would not apply here because tossing a coin is an an independent event. An independent event is one with replacement.

A particular electric utility charges customers different rates depending on their daily rate of energy consumption: $0.05/kWh up to 20 kWh, and $0.10/kWh for all energy usage above 20 kWh in any 24-hour period. (a) Calculate how many 100 W light bulbs can be run continuously for less than $10 per week. (b) Calculate the daily energy cost if 2000 kW of power is used continuously.

Answers

Answer:

(a) the number of 100W light bulbs is 11

(b) the daily cost of 2000 kW is $4,800

Step-by-step explanation:

charge of energy consumption up to 20 kWh = $0.05/kWh

charge of energy consumption above 20 kWh = $0.10/kWh

(a) number of 100 W light bulbs that can be run continuously for less than $10 per week

Total energy consumed by 100 W in 1 week = (0.1 kW) x (7 x 24 h)

                                                                          = 16.8 kWh

Charge associated with this consumption = $0.05/kWh

let the number of 100 W light bulbs = n

[tex]n(\frac{\$ 0.05}{kWh} \times 16.8 kWh) = \$10\\\\n(0.84) = 10\\\\n = \frac{10}{0.84} \\\\n = 11.9[/tex]

Since 0.9 is not a whole number, the number of 100 W light bulbs is 11.

(b) if 2000 kW is used continuously

total energy consumption = 2000 kW x 24 h = 48,000 kWh

The daily cost is calculated as;

[tex]= \frac{\$0.10 }{kWh} \ \times \ 48,000 kWh\\\\= \$ 4,800[/tex]

A particular electric utility charges customers different rates depending on their daily rate of energy consumption :

(a) the number of 100W light bulbs is 11

(b) the daily cost of 2000 kW is $4,800

"Energy Consumption"

Given :

Charge of energy consumption up to 20 kWh = $0.05/kWh

Charge of energy consumption above 20 kWh = $0.10/kWh(

Part a)

Number of 100 W light bulbs that can be run continuously for less than $10 per week

Total energy consumed by 100 W in 1 week = (0.1 kW) x (7 x 24 h)Total energy consumed by 100 W in 1 week = 16.8 kWh

Charge associated with this consumption = $0.05/kWh

Let the number of 100 W light bulbs = n[tex]n\left(\frac{\$0.05}{kWh}\cdot16.8kWh\right)=\$10\\n\left(0.84\right)=10\\n=\frac{10}{0.84}\\n=11.9[/tex]

Since 0.9 is not a whole number.

Thus, the number of 100 W light bulbs is 11.

Part b)

2000 kW is used continuously

Total energy consumption = 2000 kW x 24 h

Total energy consumption  = 48,000 kWh

The daily cost is calculated by:

[tex]\frac{\$0.10}{kWh}\cdot48000\ kWh

Daily cost=\$4800[/tex]

The volume, of a rectangular solid with length L, width W, and height H is given by the formula V = LWH.
Use this formula to write a polynomial in standard form that models, or represents, the volume of the open box.
The volume of the open box is ____

Answers

Answer:

[tex]V(x) = 4x^3-34x^2+66x[/tex]

Step-by-step explanation:

Polynomials

We'll apply the polynomials to geometry.

The volume of a rectangular box can be calculated as

V = LWH

Where L is the length, W is the width, and H is the height of the box.

The figure shows the three dimensions as a function of the variable x:

W = 6 - 2x

L = 11 - 2x

H = x

Substituting in the formula of the volume:

[tex]V(x) = (11-2x)(6-2x)(x)[/tex]

Multiplying the first two factors:

[tex]V(x) = (66-22x-12x+4x^2)(x)[/tex]

Simplifying:

[tex]V(x) = (66-34x+4x^2)(x)[/tex]

Multiplying by x:

[tex]V(x) = 66x-34x^2+4x^3[/tex]

Reordering:

[tex]\boxed{V(x) = 4x^3-34x^2+66x}[/tex]

Answers

Answer:

1. s + 7 = 9

2. 5r - 4 = 21

3. t - s = 5

4. u + r = 6

5. 11t - 7 = 70

10. 2t with an exponent of 2-18 = [tex](2t)^{2} - 18 = 178[/tex]

Step-by-step explanation:

1. If r = 5, s = 2, t = 7, and u = 1 then,

s + 7  = 2 + 7 = 9

2. If r = 5, s = 2, t = 7, and u = 1 then,

5r - 4  = 5(5) - 4 = 25 - 4 = 21

3. if r = 5, s = 2, t = 7, and u = 1 then,

t - s  = 7 - 2 = 5

r with an exponent of 2 +8 = [tex]r^{2} + 8 = 5^{2} + 8 = 25 + 8 = 33[/tex]  

9. If r = 5, s = 2, t = 7, and u = 1 then,

Systematic random sampling involves a selection technique in which samples are selected at fixed intervals. Hence, the true statement is "Systematic random sampling can be used, even if knowledge of the entire population is not known."

Systematic random sampling would fail to catch all patterns because the samples are selected at periodically at fixed intervals, hence, the possibility of missing pattern is very possible.

Starting point could be at any point and hence, might not be the first sample in the population.

However, without knowing the entire population size, systematic random samples could be selected from the population.

A candy bar that originally sold for $0.65 undergoes a 7% price increase each year. Find the new cost of the candy bar after 15 years. Round your answer to the nearest cent.
The new cost of the candy bar after 15 years is $

Answers

Answer:

10.4325

Step-by-step explanation:

For 1 year:   (0.65) + (0.65)(0.07) = 0.6955

For 15 years: 0.6955 X 15 = 10.4325

All together: (0.65+(0.65*0.07))*15 = 10.4325

The new cost of the candy bar after 15 years is $1.8.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, a candy bar that originally sold for $0.65 undergoes a 7% price increase each year.

Use Amount = Principal(1+R/100)ⁿ, where n is number of years.

Total amount = 0.65(1+7/100)¹⁵

= 0.65(1.07)¹⁵

= 0.65×2.759

= $1.8

Therefore, the new cost of the candy bar after 15 years is $1.8.
