Answer:

x = \(-\frac{4}{3}\)

Step-by-step explanation:

Distributive Property:

3 (x - 4) = 12x

3x - 12 = 12x

Combine like terms and isolate the variable:

3x - 12 = 12x

-12 = 9x

\(-\frac{4}{3}\) = x

x = \(-\frac{4}{3}\)

Answer:

x = \(\frac{-4}{3}\)

Step-by-step explanation:

3(x - 4) = 12x

3x - 12 = 12x --->by the distributive property of equality

-9x = 12 ---> subtraction property of equality

x = -9/12 ---> division property of equality

x = -4/3 as simplified

Hi there, here's your answer:

We have -1 < x ≤ 2 and -2 ≤ x < 3

Let's first solve both the inequalities one at a time.

Case 1:

-1 < x ≤ 2

The solution set for this inequality is (-1 , 2]

Case 2:

-2 ≤ x < 3

The solution set for this inequality is [-2 , 3)

Now, the values that satisfy both these inequalities can be taken from the solution set of case 1.

Thus, we get a new solution set for the satisfactory values.

New solution set = (0,2]

The required integer values are:

0, 1 and 2.

Hope this helps!

Answer: 0, 1, 2

Step-by-step explanation:

0 is less then 2 and 3 and greater than -1 and -2

Same for 1 and 2, but for 2 in the first equation it is equal but look at these signs \(\leq \geq\)

It means equal or less/greater than.

2 is = 2 so it satsifys the first equation.

The type of association you are referring to is called a spurious correlation. In a spurious correlation, there is a relationship between two variables, but the relationship is actually caused by a third variable, also known as a confounding variable. This can lead to misleading conclusions if the third variable is not taken into account.

The type of association that occurs when there is a relationship between two variables, but the relationship is caused by a third variable is called a spurious association or a confounding variable. In this case, the relationship between the two variables is not a direct causal relationship, but is instead influenced by the third variable. It is important to identify and control for confounding variables in order to accurately interpret the relationship between the two variables of interest.

DE = 7

Step-by-step explanation:

I don't have a great way of explaining so stay with me.

Both of these triangle are supposedly congruent since you can find DE.

You have to rotate CDE to line up correctly with FGH.

C and F are the same. D and G are the same. E and H are the same.

So after you match them up you can see the CD and FG are are on the same line.

If you do 13\(\frac{1}{3}\) divided by 8 (or FG divided by CD) you get 1\(\frac{2}{3}\)

After you match them up you can also see that CE and FH are on the same line.

If you do 10 divided by 6 (or FH divided by CE) you also get 1\(\frac{2}{3}\)

With this pattern you should be able to figure  out that if you divide 11\(\frac{2}{3}\) by 1\(\frac{2}{3}\) that you will find DE.

DE is 7

Answer:

118.7 inches squared.

Step-by-step explanation:

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

Diameter is the length across the entire circle, the line splitting the circle into two identical semicircles.

The expression for solving the area of a circle is A = π × \(r^{2}\).

To solve for the semicircle above, we can divide the diameter into 2 to get the radius.

So, the radius of the upper semicircle is 6 inches.

If the radius of a circle is 6 inches, then you can substitute r for 6 into the formula.

This simplifies to A = 36π. If a semicircle if half the size of a normal circle, then it will be A = 18π, because 36 ÷ 2 = 18.

To solve for the lower semicircle, we can do the same this as we did above.

But wait, we don't know the radius or diameter!

No worries! To solve for the diameter of the circle, we can take the line that is parallel to the semicircle (the one that has a length of 12in) and subtract 6 from it. We subtract 6 from it because the semicircle takes up the remaining length of the line, not including the 6in.

To solve for the lower semicircle, we can divide the diameter by 2 to get the radius.

So, the radius of the circle is 3.

Now we can insert 3 into the expression.

This simplifies to A = 9π. If a semicircle if half the size of a normal circle, then it will be A = 4.5π because like above, 9 ÷ 2 = 4.5.

Adding the two semicircles together:

So, the area of both semicircles is approximately 70.6858 square inches.

To solve for the area of a rectangle we use the expression:

Inserting the dimensions of the rectangle:

So, the area of the rectangle is 48 square inches.

Adding the two areas together:

Therefore, the area of the entire figure, rounded to the nearest tenth is \(118.7\) \(in^{2}\).

Answer:

47°

Step-by-step explanation:

Given that m<BOC = 6x + 29, m<AOB = 3x + 124, and m<AOC is a straight angle, therefore, m<AOC = 180°.

m<BOC +m<AOB = 180°

6x + 29 + 3x + 124 = 180

Solve for x

6x + 3x + 29 + 124 = 180

9x + 153 = 180

Subtract both sides by 153

9x = 180 - 153

9x = 27

Divide both sides by 9

x = 3

m<BOC = 6x + 29

Plug in the value of x

m<BOC = 6(3) + 29

m<BOC = 18 + 29 = 47°

Answer:

Yes, it is correct.

Angle A is visually not much less than 55 degrees, so we can determine without a protractor that angle A is 35 degrees.

A = 1/2 ∫[(3sinθ)² - (1 + sinθ)²] dθ from θ = π/6 to θ = 5π/6

To find the area of the region that lies inside the circle r = 3sinθ and outside the cardioid r = 1 + sinθ, you need to set up an integral in terms of θ. First, find the points of intersection by setting the equations equal to each other:

3sinθ = 1 + sinθ

Solve for θ to find the points of intersection:

2sinθ = 1
sinθ = 1/2
θ = π/6, 5π/6

Now, set up the integral for the area. The area of a polar curve is given by the formula:

A = 1/2 ∫(r² dθ)

So the integral for the area inside the circle and outside the cardioid is:

A = 1/2 ∫[(3sinθ)² - (1 + sinθ)²] dθ from θ = π/6 to θ = 5π/6

Do not evaluate the integral, as per the instructions. This expression represents the area of the region that lies inside the circle and outside the cardioid.

To determine if a camphor reduction was successful, one can use techniques such as gas chromatography or high-performance liquid chromatography to analyze the reaction mixture for the presence of the desired product.

Camphor reduction is a chemical reaction in which camphor is converted to its corresponding alcohol, called borneol. To determine if the reduction was successful, one must analyze the reaction mixture for the presence of borneol. This can be done using analytical techniques such as gas chromatography (GC) or high-performance liquid chromatography (HPLC).

GC works by separating the components of a mixture based on their boiling points, while HPLC separates the components based on their interaction with a stationary phase. Both techniques can be used to identify the presence and quantity of borneol in the reaction mixture. The absence of any other byproducts or impurities can also indicate a successful reduction.

There is a 30.85% chance that someone will have to wait longer than 6 minutes.

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

z = (raw score - mean) / standard deviation

So,

We can write,

Mean of 6 minutes and variance = 1 minutes, hence:

Standard deviation = √variance = √1 = 1 minutes

For > 6 minutes:

z = (6 - 5)/2 = 1/2=0.5

P(z > 0.5) = 1 - P(z < 0.5)

P(z > 0.5) = 1 - 0.6915

P(z > 0.5) = 0.3085

Therefore,

There is a 30.85% chance that someone will have to wait longer than 6 minutes.

y = -3x + 19

Step-by-step explanation:

The probability of the shorter segment being less than 14 times the longer segment is 1/15.

The line segment of length l can be divided into two segments of lengths x and y, such that x + y = l. Since the point is chosen at random, the probability of x being shorter than 14y is the same as the probability of y being longer than x/14. Since the point can be chosen anywhere along the line segment, the probability of the ratio of x to y being less than 14 is equal to the probability of x/y being less than 14, which is 1/15. Therefore, the probability of the ratio of the shorter to the longer segment being less than 14 is 1/15.

To find the initial number of pears at the grocery store, you need to consider that 455 pears represent 70% (100% - 30%) of the total number of pears. The grocery store started with 1517 pears.

We know that the grocery store sold 30% of its pears, which means they have 70% of the pears remaining. We can use a proportion to figure out how many pears they started with:

30/100 = x/total pears

We can simplify this to:

0.3 = x/total pears

Now we need to solve for total pears. We can start by cross-multiplying:

0.3 * total pears = x

Next, we can substitute the information we were given:

0.3 * total pears = 455

Now we can solve for total pears:

total pears = 455 / 0.3

total pears = 1516.67 (rounded to the nearest whole number)

1750.0 lb/ft^2 + 0.5 * (190.67 ft/s)^2 + (32.2 ft/s^2) * 5000 ft = constant

Simplifying the equation will give the velocity at that point.

To calculate the velocity at a point on the wing, we can use Bernoulli's equation for incompressible flow, which relates the velocity, pressure, and elevation of a fluid.

The equation is:

P + 0.5 * ρ * V^2 + ρ * g * h = constant

Where:

P is the pressure

ρ is the density of the fluid

V is the velocity

g is the acceleration due to gravity

h is the elevation

Since the problem states that the flow is incompressible, the density ρ remains constant.

Given:

P = 1750.0 lb/ft^2

V = 130.0 mi/h

h = 5000 ft

g = 32.2 ft/s^2 (approximate value for the acceleration due to gravity)

To use consistent units, we need to convert the velocity from mi/h to ft/s:

130.0 mi/h * (5280 ft/1 mi) * (1 h/3600 s) = 190.67 ft/s

Now, let's plug the values into the Bernoulli's equation:

1750.0 lb/ft^2 + 0.5 * ρ * (190.67 ft/s)^2 + ρ * (32.2 ft/s^2) * 5000 ft = constant

Since the problem does not provide the density of the fluid, we cannot calculate the exact velocity. However, we can determine the velocity difference at that point by comparing it to a reference point. If we assume the density remains constant, we can cancel out the density term:

1750.0 lb/ft^2 + 0.5 * (190.67 ft/s)^2 + (32.2 ft/s^2) * 5000 ft = constant

Simplifying the equation will give the velocity at that point.
