Answer:

If we assume that the proportion of male and female internet users in the second study is the same as the first study (i.e., 60% female and 40% male), and that the percentage of male and female internet users who create their own blog is the same as the first study (i.e., 17% for male and 22% for female), then we can calculate the percentage of teen bloggers who are female and male.

First, we can calculate the number of male and female internet users in the second study:

Number of female internet users = 1000 x 0.5 x 0.6 = 300

Number of male internet users = 1000 x 0.5 x 0.4 = 200

Next, we can calculate the number of female and male teen bloggers in the second study, based on the percentages from the first study:

Number of female teen bloggers = 300 x 0.22 = 66

Number of male teen bloggers = 200 x 0.17 = 34

Finally, we can calculate the percentage of teen bloggers who are female and male:

Percentage of teen bloggers who are female = (66 / 1000) x 100% = 6.6%

Percentage of teen bloggers who are male = (34 / 1000) x 100% = 3.4%

Therefore, in the second study, 6.6% of teen bloggers would be female and 3.4% of teen bloggers would be male.

Answer:

(a) To write 9 N as a number in standard form, we need to express it as a number between 1 and 10 multiplied by a power of 10. To do this, we can divide 9 N by 10 until we get a number between 1 and 10:

9 N = 480 × 10^9

9 N ÷ 10 = 48 × 10^9

9 N ÷ 10^2 = 4.8 × 10^9

9 N ÷ 10^3 = 0.48 × 10^9

9 N ÷ 10^4 = 0.048 × 10^9

9 N ÷ 10^5 = 0.0048 × 10^9

Therefore, 9 N = 4.8 × 10^10.

(b) To write N as a product of powers of its prime factors, we can first factorize N:

480 × 10^9 = 2^5 × 3 × 5 × 10^9

Then, we can express 10^9 as 2^9 × 5^9 and substitute it in the factorization:

2^5 × 3 × 5 × 2^9 × 5^9 = 2^14 × 3 × 5^10

Therefore, N = 2^14 × 3 × 5^10.

(c) To find the largest factor of N that is an odd number, we need to remove all factors of 2 from the factorization of N. We can do this by dividing N by 2 as many times as possible:

N = 2^14 × 3 × 5^10

N ÷ 2 = 2^13 × 3 × 5^10

N ÷ 2^2 = 2^12 × 3 × 5^10

N ÷ 2^3 = 2^11 × 3 × 5^10

N ÷ 2^4 = 2^10 × 3 × 5^10

N ÷ 2^5 = 2^9 × 3 × 5^10

N ÷ 2^6 = 2^8 × 3 × 5^10

N ÷ 2^7 = 2^7 × 3 × 5^10

N ÷ 2^8 = 2^6 × 3 × 5^10

N ÷ 2^9 = 2^5 × 3 × 5^10

N ÷ 2^10 = 2^4 × 3 × 5^10

N ÷ 2^11 = 2^3 × 3 × 5^10

N ÷ 2^12 = 2^2 × 3 × 5^10

N ÷ 2^13 = 2 × 3 × 5^10

N ÷ 2^14 = 3 × 5^10

Therefore, the largest factor of N that is an odd number is 3 × 5^10.

There is zero context to this, so I have no clue if this helps or even answers your question. Try harder with the question next time.

An LED light bulb is 40% efficient, compared to an incandescent, which is 5% efficient which means that an LED light bulb will convert 40% of the energy used into visible light, while an incandescent light bulb will only convert 5% of the energy used into visible light.

The other 95% of the energy used by an incandescent bulb is lost as heat, making it less efficient. LEDs are much more energy efficient than incandescent bulbs. LEDs are able to produce the same amount of light as an incandescent bulb with only a fraction of the energy. This is because LEDs emit light in a narrow spectrum which reduces energy loss due to the amount of light that is not visible to the human eye. In addition, LEDs do not contain filaments that require power to heat up, meaning that much less energy is wasted as heat.

LEDs also have a longer lifespan than incandescent bulbs. This is due to the fact that LEDs have no filament to burn out, meaning they can last up to 50,000 hours or more. On the other hand, an incandescent bulb typically has a lifespan of around 1,000 hours. This means that an LED light bulb can potentially last up to 50 times longer than an incandescent bulb.

The correct option is A) With sample size 10, the tails of the curve of the t-distribution have more area than the tails of the curve of the z-distribution.

Explanation:Given:P(t > 1.96) = 0.0408P(t < -1.96) = 0.0408The t-distribution is different from the z-distribution because it has a thicker tail.The tail is thicker since the t-distribution is determined by the sample size, whereas the z-distribution is determined by the population size (the t-distribution is estimated with the standard error of the mean in this case).

A t-distribution with small degrees of freedom has a much thicker tail than a z-distribution with the same degrees of freedom. Because sample size is related to the degrees of freedom, it makes sense that t-distributions with smaller sample sizes will have thicker tails.

The population variance is replaced with the sample variance in the estimation of the t-distribution. As a result, the t-distribution has heavier tails than the z-distribution.

No, you do not have to worry about perfect multicollineariy in the multiple regression model.

Perfect multicollinearity occurs when two or more independent variables are perfectly correlated, and it can lead to inaccurate estimates of the coefficients. The Ordinary Least Squares (OLS) estimator can still be computed in this situation, but the standard errors of the coefficients will be inflated. To minimize the effects of multicollinearity, you can use regularization methods such as Ridge Regression or Lasso Regression.

The conic section represented by the equation. 2x + 5y - 7 = 0 is a line

The given equation is 2x + 5y - 7 = 0.

To determine the conic section represented by this equation, we can use the discriminant D:

D = B^2 - 4AC

where A, B, and C are the coefficients of x^2, xy, and y^2, respectively, in the general form of the conic section equation Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0.

In this case, A = 0, B = 0, and C = 0 (since there are no x^2, xy, or y^2 terms), so the discriminant is:

D = 0^2 - 4(0)(0) = 0

Since the discriminant is 0, the conic section represented by the equation 2x + 5y - 7 = 0 is a degenerate case, which is a line.

The inverse function for the given function F(x)=1/x² -3x +1  is given by

f⁻¹(x) =(3 ± √(9 + 4/(x - 1))) /2.

Function f(x) is equals to,

F(x)=1/x² -3x +1

Inverse of a function, we need to swap the positions of the x and y variables and then solve for y.

Let's start with the original function

f(x) = 1/x^2 - 3x + 1

Now we will swap x and y,

⇒ x = 1/y^2 - 3y + 1

Next, Solve for y in terms of x

⇒ x = 1/y^2 - 3y + 1

⇒ x - 1 = 1/y^2 - 3y

⇒ 1/(x - 1) = y^2 - 3y

⇒ 1/(x - 1) = y(y - 3)

⇒ y(y - 3) = 1/(x - 1)

⇒ y^2 - 3y - 1/(x - 1) = 0

Using the quadratic formula, solve for y to get inverse function we have,

y = (3 ± √(9 + 4/(x - 1))) / 2

Therefore, the inverse function of f(x) is equal to f⁻¹(x) =(3 ± √(9 + 4/(x - 1))) /2.

The three interior angles of a triangle measure z degrees , (x+5)degrees , and (x+25) degrees. So, the measure of one of the three angles is x+5.

The sum of the interior angles of a triangle is always 180 degrees.

Therefore, we can write an equation using the given angle measures:

z + (x+5) + (x+25) = 180

Simplifying the equation, we get:

2x + 30 + z = 180

Subtracting 30 and z from both sides, we get:

2x = 150 - z

Dividing both sides by 2, we get:

x = (150 - z) / 2 - 5

So the measure of one of the three angles is x+5, which is:

x + 5 = [(150 - z) / 2 - 5] + 5

x + 5 = (150 - z) / 2

x + 5 = 75 - z/2

The statement "Whereas the carbohydrate and fat you eat is used mostly to give you energy, protein is used mostly to build and maintain your body" is True.

What are carbohydrates, fats, and proteins?

Carbohydrates, fats, and proteins are the three macronutrients that supply our bodies with energy.

All of these nutrients, particularly proteins, are required for the development and maintenance of the human body.In terms of providing energy, carbohydrates and fats are the most effective.

Carbohydrates are the body's primary source of energy. When you consume carbohydrates, they are broken down into glucose, which is transported throughout the body to be used as energy.

Fat is the second-most efficient source of energy, and it is utilized when carbohydrate stores are depleted. Fats are broken down into fatty acids and transported throughout the body, where they are utilized as an energy source. Proteins are not the body's preferred source of energy; instead, they are mostly used to build and repair tissues in the body.

In summary, while carbohydrates and fats are primarily used to produce energy, protein is mostly used for body maintenance and growth.

Step-by-step explanation:

90 mm Hg is Zigg's mean arterial pressure.

Here's the formula for calculating MAP: MAP = (CO x SVR) + CVPR

where:

CO stands for cardiac output (measured in liters per minute).

SVR stands for systemic vascular resistance (measured in mm Hg/L/min).

CVPR stands for central venous pressure (measured in mm Hg).

Now, let's get started with the calculation of MAP.

First, let's calculate CO (cardiac output): CO = HR x SV

where:

HR is heart rate (measured in beats per minute).

SV is stroke volume (measured in milliliters per beat).

CO = 140 bpm x 95 mlCO = 13300 ml/minCO = 13.3 L/min

Next, we need to calculate SVR (systemic vascular resistance).

The formula for calculating SVR is: SVR = (MAP - CVP) / CO

where:

MAP is mean arterial pressure (measured in mm Hg).

CVP is central venous pressure (measured in mm Hg).

CO is cardiac output (measured in liters per minute).

Since we don't have CVP in this question, let's assume it to be zero.

SVR = (MAP - 0) / 13.3 L/minSVR = MAP / 13.3 L/min

Now, we can rearrange the above equation to calculate

MAP:

MAP = SVR x 13.3 L/minMAP = 60 mm Hg (diastolic pressure) + 1/3 (systolic pressure - diastolic pressure)MAP = 60 mm Hg + 1/3 (150 mm Hg - 60 mm Hg)MAP = 60 mm Hg + 30 mm HgMAP = 90 mm Hg

The correct conclusion that can be drawn from the plot is that the plant population had a significantly lower mean root length after the major drought occurred.

Explanation:

A frequency polygon is a graphical representation of a frequency distribution using line segments connected to points that indicate the midpoint of each class interval.

The horizontal axis shows the measurement variable, while the vertical axis shows the number of occurrences of the variable for each bin. The midpoint of each bin is used to represent the distribution of data that falls within that bin's range.

Since the values of adjacent bins overlap, the lines are connected. The points are connected by straight lines in a frequency polygon.

In this case, the conclusion that can be drawn from the plot is that the plant population had a significantly lower mean root length after the major drought occurred.

The peak of the frequency polygon has shifted to the left, indicating that the majority of plants have a shorter root length. The decrease in the mean root length of the plant population is due to the impact of the major drought on the island.

As a result, no plant reproduction took place, indicating a decrease in the plant population.
