Answer: [3, 2.5]

Step-by-step explanation:

The required quotient of the expression 16x⁻² - 8x⁻² - 2x⁻² divided by 2x is 4x⁻³ - x⁻¹⁰.

Arithmetic involves the basic operations of addition, subtraction, multiplication, and division, as well as more advanced operations such as exponents, roots, logarithms, and trigonometric functions.

Here,
To simplify the given expression, we can start by factoring out the common factor of 2x from the numerator. This gives:

(16x⁻² - 8x⁻² - 2x⁻⁹) / 2x

Next, we can simplify the terms in the numerator by combining the like terms:

= (4x⁻² - x⁻⁹) / x

= 4x⁻²⁻¹ - x⁻⁹⁻¹
= 4x⁻³ - x⁻¹⁰

= 4x⁻³ - x⁻¹⁰

Therefore, the quotient of the expression 16x⁻² - 8x⁻² - 2x⁻² divided by 2x is 4x⁻³ - x⁻¹⁰.

Therefore, the height range that encompasses 99.7% of adolescent women is roughly between 55.9 and 68.1 inches.

It reveals the average deviation of each number from the norm. When it comes to normally distributed, a large standard deviation denotes that values are typically out of the mean, whereas a smaller standard deviation denotes that values are grouped closely around the mean.

The 68-95-99.7 rule is a way to remember the percentage of data that falls within certain numbers of standard deviations from the mean in a normal distribution. Specifically:

Using this rule, we can answer the following questions:

About 68% of young women have heights within 1 standard deviation of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 1 standard deviation from the mean:

64 inches ± 2.7 inches

So the range of heights that includes about 68% of young women is approximately 61.3 inches to 66.7 inches.

    2. What is the range of heights that includes about 95% of young women?

About 95% of young women have heights within 2 standard deviations of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 2 standard deviations from the mean:

64 inches ± 2(2.7 inches)

So the range of heights that includes about 95% of young women is approximately 58.6 inches to 69.4 inches.

     3. What is the range of heights that includes about 99.7% of young women?

About 99.7% of young women have heights within 3 standard deviations of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 3 standard deviations from the mean:

64 inches ± 3(2.7 inches)

So the range of heights that includes about 99.7% of young women is approximately 55.9 inches to 68.1 inches.

Answer

The shape of sampling distribution of ^p is approximately normal because n < greater than 0.05N and np (1-p) > less than 10.

Step-by-step explanation:

The shape of the sampling distrbution of p is approximately normal because n <= 0.05N and np(1 -p) > 10.

The distribution of the sampling distribution of sample proportions of a proportion p in a sample of size n is defined by the central limit theorem, where:

As long as these two conditions are respected:

n≤ N

np(1-p) > 10.

Here, we have the parameters

n= 700, p = 0.172, N= 15, 000

So, n/N = 0.0466 < 0.05

and, np(1-p)

= 700 x 0.172 ( 1- 0.172)

= 99.69 >10

Then the shape is approximately normal.

We can infer that the function y = 2 + log2(x - 1) has the following final behaviour:

A function is a relationship between a number of inputs and outputs. Simply described, a function is an association between inputs in which each input is coupled to exactly one output. There is a range, codomain, and domain for every function. A function is typically referred to as f(x), where x is the input. Y = f is a common way to represent a function (x).

A function in mathematics is a certain configuration of the inputs (also known as the domain) and their outputs (also known as the codomain), where each input has precisely one output and the output can be connected to its input.

from the question;

We may look at what happens to the function as x gets closer to positive and negative infinity to figure out the final behaviour of the function

y = 2 + log2(x - 1).

The formulas (x - 1) and log2(x - 1) also approach infinity as x gets closer to positive infinity. As a result, y increases as x moves closer to positive infinity. The following can be written:

lim x→∞ 2 + log2(x - 1) = ∞

Expression (x - 1) moves closer to zero and log2(x - 1) moves closer to negative infinity as x moves towards 1 from the right. So, as x moves closer to 1 from the right, y moves closer to negative infinity. The following can be written:

lim x→1+ 2 + log2(x - 1) = -∞

This leads us to the following conclusion about the final behaviour of the function y = 2 + log2(x - 1):

Step-by-step explanation:

Answer:

Step-by-step explanation:

Therefore, 12 minutes of play awards 4.5 points.

The constant of proportionality is 1/4, which means that for every minute of play, 1/4 point is awarded and 5 points are awarded for 20 minutes of play.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that for every 4 minutes of play, 1/2 point is awarded.

For every 12 minutes of play, 1 1/2 points are awarded.

We can set up a proportion to find the constant of proportionality:

(1/2 point) / (4 minutes) = (3/2 points) / (12 minutes)

Simplifying the left side, we get:

1/8 = (3/2 points) / (12 minutes)

Multiplying both sides by 12, we get:

1.5 = (3/2)P

P = (1.5) x (2/3) = 1

Therefore, the constant of proportionality is 1/4, which means that for every minute of play, 1/4 point is awarded.

By constant of proportionality, the equation that represents the relationship between the number of points awarded and the amount of time played:

P = (1/4)t

To find the number of points awarded for 20 minutes of play, we can use the equation P = (1/4)t:

P = (1/4)(20)

= 5

Hence, the constant of proportionality is 1/4, which means that for every minute of play, 1/4 point is awarded and 5 points are awarded for 20 minutes of play.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To calculate the profit for selling 300 vetkoek every week, we need to first calculate the total revenue generated and the total cost of producing the vetkoek.

Total revenue = Price per vetkoek x Number of vetkoek sold

Total revenue = 10 x 300 = 3000

Total cost = Cost per vetkoek x Number of vetkoek sold

Total cost = 3.80 x 300 = 1140

Profit = Total revenue - Total cost

Profit = 3000 - 1140 = 1860

Therefore, the profit for selling 300 vetkoek every week at a cost of 3.80 per vetkoek and selling them for 10 each is 1860.

The chain rule states that the derivative D of a composite function is given by a product, as D(f(g(x))) = Df(g(x)) ∙ Dg(x).

In other words, the first factor on the right, Df(g(x)), indicates that the derivative of f(x) is first found as usual, and then x, wherever it occurs, is replaced by the function g(x).

Given:

By chain rule we can write z= f(x, y) = f( x(t), y(t))

dz/ dt = df/ dx . dx/ dt + df/ dy. dy/dt

So, df/ dx = [tex]e^y[/tex]

Answer:

the greater integer is "y", which is 13.

Step-by-step explanation:

Let's call the odd integer "x", and the next consecutive integer "y". Since "y" is the next consecutive integer after "x", we know that:

y = x + 2

We are told that the sum of "x" and 4 times "y" is 63. We can set up an equation to represent this:

x + 4y = 63

Now we can substitute the expression for "y" in terms of "x" into this equation:

x + 4(x + 2) = 63

Simplifying this equation, we get:

x + 4x + 8 = 63

5x + 8 = 63

Subtracting 8 from both sides, we get:

5x = 55

Dividing both sides by 5, we get:

x = 11

So the odd integer is 11. We can use the expression for "y" in terms of "x" to find the next consecutive integer:

y = x + 2 = 11 + 2 = 13

Therefore, the greater integer is "y", which is 13.

Answer:

13

Step-by-step explanation:

there is an interval of 2 between consecutive odd numbers

let n and n + 2 be the 2 consecutive integers , then

n + 4(n + 2) = 63 , that is

n + 4n + 8 = 63

5n + 8 = 63 ( subtract 8 from both sides )

5n = 55 ( divide both sides by 5 )

n = 11

then larger integer is n + 2 = 11 + 2 = 13

Answer: (a) Since the time to get the order follows a uniform distribution between 19 to 35 minutes, the probability of getting the order in any interval of time within this range is proportional to the length of that interval. Therefore, the probability of taking at least 23 minutes to get the order is:

P(X ≥ 23) = (35 - 23) / (35 - 19) = 0.4

Rounding to 4 decimal places, the probability is:

P(X ≥ 23) ≈ 0.4000

(b) If you arrive at Tim Horton's at 7:30am and your friends show up at 8:00am, you have 30 minutes to receive your order. Since the time to get the order follows a uniform distribution, the probability of receiving the order before your friends show up is the probability of getting the order in 30 minutes or less, which is:

P(X ≤ 30) = (30 - 19) / (35 - 19) = 0.5789

Rounding to 4 decimal places, the probability is:

P(X ≤ 30) ≈ 0.5789

(c) Let's call the time in minutes to get the order that is longer than 10% of the time as t. Since the distribution is uniform, we know that the probability of taking longer than t minutes is 0.1. Therefore, we can write:

(35 - t) / (35 - 19) = 0.1

Solving for t, we get:

t = 19 + 0.9(35 - 19) = 32.4

Rounding to 2 decimal places, we get:

t ≈ 32.40 minutes

Therefore, 10% of the time it takes longer than 32.40 minutes to get the order.

In response to the given question, we have that Therefore, on Tuesday, equation the yield was 2.92%, and on Monday, it was 2.96%.

In a math equation, two assertions are connected by the equals sign (=), which denotes equivalence. A mathematical assertion used in algebraic equations establishes the equivalence of two mathematical statements. For instance, in the equation 3x + 5 = 14, the equal sign creates a space between the values 3x + 5 and 14.

Divide the yearly dividend by the share price to determine the yield, then multiply the result by 100 to get the percentage:

Tuesday's yield is calculated as (Annual dividend / Share Price) times 100.

Tuesday's yield is calculated as ($2.10 / $72) times 100, which is 2.92%.

Tuesday's closing price minus Monday's closing price is the difference.

The price on Monday was $72 minus $0.95.

$71.05 was the final price on Monday.

We apply the same procedure as previously to determine the yield as of Monday's close:

Monday's yield is calculated as (annual dividend / share price) x 100.

Yield on Monday is equal to ($2.10 / $71.05) times 100, or 2.96%.

Therefore, on Tuesday, the yield was 2.92%, and on Monday, it was 2.96%.
