In a large population, 67% of the households have cable tv. A simple random sample of 64 households is to be contacted and the sample proportion computed. What is the mean and standard deviation of the sampling distribution of the sample proportions?

Answers

Answer:

The mean of the sampling distribution of the sample proportions is the same as the population proportion, which is 0.67.

The standard deviation of the sampling distribution of the sample proportions can be calculated using the formula:

σp = sqrt [p * (1 - p) / n]

where p is the population proportion (0.67), n is the sample size (64), and σp is the standard deviation of the sampling distribution of the sample proportions.

Plugging in the values, we get:

σp = sqrt [0.67 * (1 - 0.67) / 64]

= sqrt [0.2211 / 64]

= 0.061

Therefore, the standard deviation of the sampling distribution of the sample proportions is 0.061.

In the quadrilateral, using the sum of angles properties we can find the value of ∠G to be 90°.

What is a quadrilateral?

A closed shape called a quadrilateral is created by connecting four points, any three of which cannot be collinear. A quadrilateral is a polygon with four sides, four angles, and four vertices, to put it simply.

The Latin root of the word "quadrilateral" is "quadra," which means four, and "latus," which means sides. It should be noted that a quadrilateral's four sides might or might not be equal to one another.

In the given quadrilateral,

The sum of the opposite angles is 180°.

So, (2x+43) ° + (3x+21) ° = 180°

⇒ 2x+3x+43+21=180

⇒ 5x = 116

⇒ x = 116/5

= 23.2

Now the value of ∠G = 2x+43

= (2 × 23.2) + 43

Determine the equation of the circle graphed below.

Answers

Answer:

(x - 3)² + (y + 4)² = 29

Step-by-step explanation:

the equation of a circle in standard form is

(x - h )² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

we are given the centre  and require to find the radius r

the distance from the centre to a point on the circle gives r

using the distance formula to find r

r = [tex]\sqrt{(x_{2}-x_{1 )^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (3, - 4 ) and (x₂, y₂ ) = (8, - 2 )

r = [tex]\sqrt{(8-3)^2+(-2-(-4))^2}[/tex]

Apple has a sale for new iPhone 12
.They are selling the phones for $795
. That is a 35% mark up from their wholesale priceWhat is Apples' cost for the iPhone 12?

Answers

Cost price of iPhone12 is $588.89

To determine Apple's cost for the iPhone 12, we need to work backwards from the retail price of $795 and account for the 35% mark-up.

If we assume that the retail price includes the mark-up and the wholesale price is the original cost price of the product, we can set up an equation to solve for the cost:

Cost + 35% of Cost = Retail Price

Let's simplify the equation by converting the percentage to a decimal:

Cost + 0.35Cost = $795

Combining like terms:

1.35Cost = $795

Dividing both sides by 1.35:

Cost = $588.89

Therefore, Apple's cost for the iPhone 12 is approximately $588.89. This means that Apple makes a profit of $206.11 per phone sold.

It's important to note that this calculation is based on the assumption that the retail price includes only the 35% mark-up and not additional costs such as marketing, shipping, and other expenses that Apple incurs. Additionally, the actual wholesale cost may vary depending on a number of factors such as production volume, component prices, and supplier negotiations.

While we can estimate Apple's cost for the iPhone 12 based on the mark-up and retail price, it's important to keep in mind that the actual cost and profit margins may be more complex and variable in reality.

Answers

The function f(x) = 223 - 6a? - 144x + 7 is increasing on the interval (-00, A) U (B, co)and on the interval (-00, B), the function is decreasing.

What is function?

Function in mathematics is a relation or mapping between input and output values. It describes a relationship in which each input value has a single corresponding output value. Functions are an essential part of mathematics, and they are used to model real-world situations. They are also used to solve equations, graph functions, and find the area of a region.

A function is increasing if its rate of change is positive; that is, the function is always getting larger as the independent variable (in this case, x) increases. Conversely, a function is decreasing if its rate of change is negative; that is, the function is always getting smaller as the independent variable increases.

The function f(x) = 223 - 6a? - 144x + 7 is increasing on the interval (-00, A) U (B, co). This means that the rate of change of the function is positive on the specified interval. That is, as x increases within the interval, the value of the function will also increase.

The value of A is the point at which the function changes from increasing to decreasing. That is, on the interval (-00, A), the function is increasing, but on the interval (A, B), the function is decreasing. The value of A can be found by setting the first derivative of the function (the rate of change) equal to 0.

The value of B is the point at which the function changes from decreasing to increasing. That is, on the interval (B, ∞), the function is increasing, but on the interval (-00, B), the function is decreasing. The value of B can be found by setting the first derivative of the function equal to 0.

The value of C is the point at which the function changes from concave up to concave down. That is, on the interval (C, ∞), the function is concave up, but on the interval (-00, C), the function is concave down. The value of C can be found by setting the second derivative of the function equal to 0.

You answered 7 out of 11 correctly. Asking up to 12.
2 attempts

Answers

The sales of bottled water and carbonated soft drinks will be the same in the year 2028 (in 5.323 years).

How to find the amount sold will be same

To find the year when the sales of soda and water will be equal, we need to solve the equation:

Soda = Water

12.5 - 0.2475t = 8.2 + 0.56t

where

t = time

collecting like terms

12.5 - 8.2 = 0.2475t + 0.56t

4.3 = 0.8075t

Then we can solve for t by dividing both sides by 0.8075:

t ≈ 5.323

If t is in years, this tells us that the sales of soda and water will be equal in approximately 5.323 years.

To find the year when this will happen, we need to add 5.323 to the current year.

Assuming the current year is 2023, we get:

2023 + 5.323 ≈ 2028.323

Assume Martina used x pounds of type A coffee in her blend. Then, based on the information provided, she used 4 pounds of type B coffee.

Type A coffee costs $4.30 per pound, so x pounds of type A coffee costs $4.30x dollars.

Because the entire cost of the blend is given as $689.00, we may formulate the following equation:

4.30x + 22.20x = 689.00

Mixing similar phrases yields:

1 + 1 + 4 + 3 + 8 + 10 + 15 + 22 + 11 = 75.

We are given a frequency distribution, hence for each interval we take the midpoint, and thus the sum of the values is given as follows:

S = 1 x (52 + 57) + 4 x 62 + 3 x 67 + 8 x 72 + 10 x 77 + 15 x 82 + 22 x 87 + 11 x 92

S = 6060.

Hence the mean is given as follows:

6060/75 = 80.8.

Step-by-step explanation:

According to The Food and Drug Administration (FDA), 400 milligrams (mg) a day is considered a safe amount of daily caffeine consumption which is about 4 to 5 cups of coffee. We suspected that people who visit coffee shops in the morning drink more coffee on average than people who visit coffee shops in the afternoon. During one day, we randomly sampled 8 people who entered a given coffee shop in the morning and 8 people who entered the coffee shop in the afternoon. We recorded each person's average daily caffeine consumption (in mg).

The apprοximate 95% cοnfidence interval fοr mοrning - afternοοn caffeine cοnsumptiοn is (70.37, 229.63) mg.

What is standard errοr?

Standard errοr is a statistical measure οf the variability οf a sample mean frοm the true pοpulatiοn mean, representing the precisiοn οf an estimate. It's calculated as the standard deviatiοn οf the sample mean divided by the square rοοt οf the sample size.

a. The standard errοr οf (xmοrning - xafternοοn) can be calculated as fοllοws:

Standard errοr = sqrt[(s₁²/n₁) + (s₂²/n₂)]

b. Tο cοnstruct an apprοximate 95% cοnfidence interval fοr mοrning - afternοοn caffeine cοnsumptiοn, we can use the fοllοwing fοrmula:

(xmοrning - xafternοοn) +/- t(alpha/2, df) * standard errοr

Assuming a twο-tailed test and a significance level οf 0.05, the degrees οf freedοm are 14 (8+8-2).

Let's assume that the sample mean caffeine cοnsumptiοn fοr the mοrning grοup is 500 mg with a sample standard deviatiοn οf 80 mg, and the sample mean caffeine cοnsumptiοn fοr the afternοοn grοup is 350 mg with a sample standard deviatiοn οf 60 mg. Plugging in the values intο the fοrmula, we get:

(xmοrning - xafternοοn) +/- t(alpha/2, df) * standard errοr

= (500 - 350) +/- 2.145 * sqrt[(80²/8) + (60²/8)]

= 150 +/- 79.63

= (70.37, 229.63)

The normal distribution is  X ~ N(17, 0.8), the median is equal to mean which is 17 feet, the z-score is 2.5, the probability that a randomly selected giraffe will be shorter than 18 feet tall is 0.8944.

What is the distribution of X

a. The distribution of X is normal, which we can write as X ~ N(17, 0.8).

b. Since the normal distribution is symmetric, the median is equal to the mean, which is 17 feet.

c. To find the z-score for a giraffe that is 19 feet tall, we use the formula:

z = (x - μ) / δ

where x is the height of the giraffe, mu is the mean height of the population (17 feet), and sigma is the standard deviation (0.8 feet). Plugging in the values, we get:

z = (19 - 17) / 0.8 = 2.5

So the z-score for a giraffe that is 19 feet tall is 2.5.

d. To find the probability that a randomly selected giraffe will be shorter than 18 feet tall, we need to find the area under the normal distribution curve to the left of x = 18. We can use a standard normal distribution table or a calculator to find this area, or we can standardize the value of x and use the standard normal distribution table or calculator. Using the latter method, we have:

z = (x - μ) / δ = (18 - 17) / 0.8 = 1.25

Looking up the area to the left of z = 1.25 in a standard normal distribution table or using a calculator, we find that the probability is approximately 0.8944. So the probability that a randomly selected giraffe will be shorter than 18 feet tall is 0.8944.

e. To find the probability that a randomly selected giraffe will be between 16.7 feet and 17.5 feet tall, we need to find the area under the normal distribution curve between x = 16.7 and x = 17.5. Again, we can standardize the values of x and use a standard normal distribution table or calculator. We have:

z1 = (16.7 - 17) / 0.8 = -0.38

z2 = (17.5 - 17) / 0.8 = 0.63

Looking up the area between z1 = -0.38 and z2 = 0.63 in a standard normal distribution table or using a calculator, we find that the probability is approximately 0.2981. So the probability that a randomly selected giraffe will be between 16.7 feet and 17.5 feet tall is 0.2981.

f. The 90th percentile for the height of the giraffe is the height x such that 90% of the giraffes have a height below x. In other words, we need to find the value of x such that the area under the normal distribution curve to the left of x is 0.9. Using a standard normal distribution table or calculator, we can find the z-score corresponding to the 90th percentile, which is approximately 1.28. We can then use the formula for z-score to find the corresponding height x:

z = (x - μ) / δ

1.28 = (x - 17) / 0.8

Solving for x, we get:

x = 17 + 1.28 * 0.8 = 18.024

So the 90th percentile for the height of the giraffe is 18.024 feet.

The AP Chemistry class is mixing 100 pints of liquid together for an experiment. Liquid A contains 10% acid, liquid B contains 40% acid, and liquid C contains 60% acid. If there are twice as many pints of liquid A than liquid B, and the total mixture contains 45% acid, find the number of pints needed for each liquid.

Answers

Therefore, they need 25 pints of liquid A, 12.5 pints of liquid B, and 62.5 pints of liquid C to make the final mixture.

What is equation?

An equation is a mathematical statement that shows that two expressions are equal. It contains one or more variables, and the goal is to solve for the value(s) of the variable(s) that make the equation true.

Given by the question.

Let's denote the number of pints of liquid A, B, and C as A, B, and C, respectively. We know that:

A + B + C = 100 (since they are mixing 100 pints in total)

We also know that the concentration of acid in the final mixture is 45%, so:

0.1A + 0.4B + 0.6C = 0.45(100) = 45

Finally, we are told that there are twice as many pints of liquid A as liquid B, so:

A = 2B

We can use these three equations to solve for A, B, and C. First, substitute A = 2B into the equation A + B + C = 100:

2B + B + C = 100

3B + C = 100

Next, substitute A = 2B into the equation 0.1A + 0.4B + 0.6C = 45:

0.1(2B) + 0.4B + 0.6C = 45

0.2B + 0.4B + 0.6C = 45

0.6B + 0.6C = 45

Simplify this equation by dividing both sides by 0.6:

B + C = 75

We now have two equations with two variables:

3B + C = 100

B + C = 75

Subtracting the second equation from the first, we get:

2B = 25

B = 12.5

Substituting this value back into B + C = 75, we get:

12.5 + C = 75

C = 62.5

Finally, using A = 2B, we get:

A = 25

What is sine function?

The ratio of a right-angled triangle's hypotenuse to its opposite side is known as the sine function in trigonometry. Use the sine function to get the unknown angle or sides of a right triangle. The sine of an angle in a right-angled triangle is the proportion between the hypotenuse and the side parallel to the angle.

The sine function defines the relationship between the opposing side and the hypotenuse.

For the first figure we can write:

sin (45) = opposite side / hypotenuse = x / 8

1/√2 = x/8

x = 8/√2 = 4√2.

For the second figure we have:

sin 60 = opposite side / hypotenuse

√3/2 = x/12

x = 12√3/2 = 6√3

Hence, the corresponding values of x for the given figures are 1. 4√2 and 2. 6√3.
