Answer: C

Step-by-step explanation:

area of rectangle = (5--2) × (2--2) = 7 × 4 = 28

area of triangle = ((12-5) × (6--6)) ÷ 2 = (7 × 12) ÷ 2 = 84 ÷ 2 = 42

total area = 28 + 42 = 70

Answer:

answer for the expression 5(–4+k) + –2(–3+–10k) is -5k - 6.

To arrive at this answer, we used the order of operations (PEMDAS) as follows:

Parentheses first: (–4+k) = k-4 and (–3+–10k) = –10k-3

Next, the multiplication: 5(k-4) = 5k-20 and -2(-10k-3) = 20k+6

Finally, the addition: -5k-20 + 20k+6 = -5k - 6 + 20k

And then we simplify further by combining the like terms:

-5k - 6 + 20k = -5k + 20k - 6 = 15k - 6

So the final answer is -5k -6

Answer:

To solve the equation 6x + 3 = 9 for x, the operations that must be performed on both sides of the equation in order to isolate the variable x are subtraction and then division.

What is a linear equation?

A linear equation in one variable has the standard form Px + Q = 0. In this equation, x is a variable, P is a coefficient, and Q is constant.

How to solve this problem?

Given that 6x + 3 = 9.

First, we have to separate variable and constants. So, we have to subtract 3 from both sides.

6x + 3 - 3 = 9 - 3

i.e. 6x = 6

Now, to solve this equation, we use division.

x = 6/6 = 1

i.e. x = 1

Therefore, to solve the equation 6x + 3 = 9 for x, the operations that must be performed on both sides of the equation in order to isolate the variable x are subtraction and then division.

Step-by-step explanation:

To solve the equation 6x + 3 = -9, you can follow the following sequence:

6x + 3 - 3 = -9 - 3

This simplifies to 6x = -12.

This simplifies to x = -2.

Therefore, the solution to the equation 6x + 3 = -9 is x = -2.

Answer:

If the video game that Ethan bought usually costs $39.99, and it was on sale for 20% off, then the discount on the game would be $39.99 x 20/100 = $8.00. To determine the final price of the game after the discount, we can subtract the discount from the original price of the game, which gives us:

Final price = $39.99 - $8.00 = $31.99

Therefore, Ethan paid $31.99 for the video game that was on sale. This can be rounded to the nearest cent to give us a final answer of:

Final price = $31.99 ≈ $32.00.

Therefore, Ethan paid $32.00 for the video game that was on sale.

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

First, combine like terms. Like terms are terms that share not only the same variable, but the same amount of that variable:

5x - 4 + 2x = 3

(5x + 2x) - 4 = 3

7x - 4 = 3

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Division

Addition

Subtraction

First, add 4 to both sides of the equation:

7x - 4 (+4) = 3 (+4)

7x  = 3 + 4

7x = 7

Next, divide 7 from both sides of the equation:

(7x)/7 = (7)/7

x = 7/7 = 1

x = 1 is your answer.

~

Answer:

x = 1

Step-by-step explanation:

5x - 4 + 2x = 3

7x - 4 = 3           (add the Xs together)

7x = 7                (add seven to both sides)

x = 1                  (divide both sides by 7)

The value of the test statistic is 9.81

The null hypothesis in this study is that the proportion of medical malpractice lawsuits that are dropped or dismissed is equal to or less than 0.5.

We will use a significance level of 0.05, which means that we are willing to accept a 5% chance of making a Type I error (rejecting the null hypothesis when it is actually true).

To test this claim, we can use a one-sample proportion test. The test statistic for a one-sample proportion test is calculated as:

z = (p - P0) / √( P0*(1 - P0) / n )

where p is the sample proportion, P0 is the hypothesized proportion under the null hypothesis, and n is the sample size.

In this case, the sample proportion is 507/779 = 0.651, and the hypothesized proportion under the null hypothesis is 0.5. Therefore, we can calculate the test statistic as:

z = (0.651 - 0.5) / √( 0.5*(1 - 0.5) / 779 ) = 9.81

This test statistic tells us how many standard errors the sample proportion is away from the hypothesized proportion under the null hypothesis. In this case, the sample proportion is almost 10 standard errors away from the hypothesized proportion of 0.5, which indicates strong evidence against the null hypothesis.

The unit of measure that represents a metric unit dosage of strength is the gram (a).

In the metric system, the gram is the standard unit for measuring mass or weight. It is commonly used in the healthcare field to quantify the amount or dosage of medication or drug strength.

Medications are often prescribed and administered in specific gram amounts, indicating the quantity of the active ingredient in the medication. For example, a doctor may prescribe a medication dosage of 500 milligrams (mg), which is equivalent to 0.5 grams.

On the other hand, grains (b), ounces (c), and tablespoons (d) are not typically used as metric units of measure for medication dosage strength. Grains are more commonly used in the imperial system, especially in the United States, to measure the weight of medications. Ounces and tablespoons are used to measure volume or liquid medications rather than dosage strength.

In the context of metric unit dosage strength, the gram is the most appropriate and commonly used unit of measure.

The linear correlation coefficient between the variables X and Y is given by r = (Sxy / sqrt(Sxx * Syy)). To find the linear correlation coefficient, we need to calculate Sxy and Sxx first.

The formula for Sxy is Sxy = Σ(xi * yi) - (Σxi * Σyi) / n, where xi and yi are the individual values of X and Y, Σ denotes the sum, and n is the sample size.

Given that the slope of the regression line is 0.375, we can deduce that Sxy = b * Sxx, where b is the slope of the regression line. Therefore, Sxy = 0.375 * Sxx.

Next, we calculate Sxx using the formula Sxx = Σ(xi^2) - (Σxi)^2 / n.

Given that S = 80, we can substitute the values into the formula to find Sxx = (80^2) - (Σxi)^2 / n.

Using the information provided in the question, we have Syy = 54.75.

Now, we can substitute the values of Sxy, Sxx, and Syy into the formula for the linear correlation coefficient: r = (Sxy / sqrt(Sxx * Syy)).

By substituting Sxy = 0.375 * Sxx, Sxx from the previous step, and Syy = 54.75 into the formula, we can calculate the value of r.

The tip of the ladder along the side of the house is slipping at a rate of approximately 0.035 ft/s when the ladder is 7.4 feet away from the house.

To solve this problem, we can use related rates. Let's denote the distance between the bottom of the ladder and the house as x (in feet) and the distance from the top of the ladder to the ground as y (in feet). We are given that dx/dt = -0.13 ft/s (negative because the bottom of the ladder is slipping away from the house). We need to find dy/dt when x = 7.4 ft.

We have a right triangle formed by the ladder, the distance along the ground (x), and the distance up the wall (y). The Pythagorean theorem gives us:

x^2 + y^2 = (23 ft)^2

Differentiating with respect to time t, we get:

2x(dx/dt) + 2y(dy/dt) = 0

Plugging in the known values, we have:

2(7.4 ft)(-0.13 ft/s) + 2y(dy/dt) = 0

Simplifying:

-1.524 ft/s + 2y(dy/dt) = 0

Now we can solve for dy/dt:

2y(dy/dt) = 1.524 ft/s

dy/dt = (1.524 ft/s) / (2y)

To find dy/dt when x = 7.4 ft, we need to find the corresponding value of y. Using the Pythagorean theorem:

(7.4 ft)^2 + y^2 = (23 ft)^2

54.76 ft^2 + y^2 = 529 ft^2

y^2 = 529 ft^2 - 54.76 ft^2

y^2 = 474.24 ft^2

y ≈ 21.78 ft

Now we can substitute y into the equation for dy/dt:

dy/dt ≈ (1.524 ft/s) / (2 * 21.78 ft)

dy/dt ≈ 0.035 ft/s

Therefore, the tip of the ladder along the side of the house is slipping at a rate of approximately 0.035 ft/s when the ladder is 7.4 feet away from the house.

Total distance:

The equation that can be used to find r, the rate of growth per year of the world population, is \(r = (7.53 / 5.88 )^{(1/20)} - 1\).

If we assume that the growth rate of the world population was constant from 1997 to 2017, then we can use the following equation:

Population in 2017 = Population in 1997 × (1 + r)²⁰

where r is the annual growth rate, and the exponent 20 represents the number of years between 1997 and 2017.

We can rewrite this equation to solve for r:

(7.53 ) = (5.88 ) × (1 + r)²⁰

Divide both sides by (5.88 ):

(7.53 ) / (5.88 ) = (1 + r)²⁰

Take the 20th root of both sides:

\((7.53 / 5.88 )^{(1/20)} = 1 + r\)

Subtract 1 from both sides:

\(r = (7.53 / 5.88 )^{(1/20)} - 1\)

Therefore, the equation that can be used to find r, the rate of growth per year of the world population, is \(r = (7.53 / 5.88 )^{(1/20)} - 1\).

Step-by-step explanation:

The statement "arcsin(sin(x)) = x for all x" is incorrect.

While it is true that for certain values of x, arcsin(sin(x)) equals x, it is not true for all values of x.

We have,

The range of the arcsin function is restricted to the interval [-π/2, π/2]. This means that the output of arcsin(x) will always be within this range.

However, the sin function has a periodic nature, oscillating between -1 and 1 as x increases.

For x values outside the interval [-π/2, π/2], the arcsin(sin(x)) expression will not yield x.

Instead, it will return a value within the range [-π/2, π/2] that has the same sine value as x.

To illustrate this, consider x = π/2 + ε, where ε is a small positive number.

In this case, sin(x) will still be equal to 1, but the arcsin(1) is

π/2, not π/2 + ε.

Therefore, the equation arcsin(sin(x)) = x does not hold for all values of x.

Thus,

The statement is only correct when x is within the interval [-π/2, π/2].

The range of arcsin(x) is restricted to this interval because sin(x) is bounded between -1 and 1 over this interval.

The equations of each of the given lines are:

Line a is: x = -4

Line b is: x = 4

Line c is: y = 4

Line d is: y = -2

Line e is: y = -¾x + 1

If we determine the slope value, m, and the y-intercept value, b, the equation of a line can be written as y = mx + b in slope-intercept form by plugging in the values of the determined variables.

For a vertical line, the equation is expressed as x = b, where b is the x-intercept of the line.

For a horizontal line, the equation would be y = b, where b is the line's y-intercept value.

Equation of line a (vertical line):

The x-intercept is -4. This means that, the equation of line a is: x = -4

Equation of line b (vertical line):

The line's x-intercept is 4. To write the equation of the line, substitute the value of the x-intercept into x = b.

Therefore, the equation of line b is: x = 4

Equation of line c (horizontal line):

The y-intercept (b) = 4. Substitute the b = 4 into y = b.

The equation of line c is: y = 4

Equation of line d (horizontal line):

y-intercept (b) = -2. Substitute b = -2 into y = b.

Equation of line d is: y = -2
