x = -4

Step-by-step explanation:

\( - 3x = 12\)

Lets divide both the sides by -3.

\( = > \frac{ - 3x}{ - 3} = \frac{12}{ - 3} \)

\( = > x = - 4\)

x= -4

-3x=12

divide x by -3 and do the same on the other side

12÷(-3)= -4

hence, x= -4

Answer:

width = 20 ft; length = 33 ft

Step-by-step explanation:

The formula for perimeter of a rectangle is P = 2l + 2w

Given that the length is seven less than twice its width, we have

\(l=2w-7\)

We need to have only one variable or we can't solve.

Thus, we have:

\(106=2(2w-7)+2w\\106=4w-14+2w\\106=-14+6w\\120=6w\\20=w\\\\l=2w-7\\l=2(20)-7\\l=40-7\\\\l=33\)

That a full cut round brilliant diamond with a 6.50 mm girdle diameter typically weighs around 1.00 carat.

carat weight is determined by a combination of a diamond's size and density. A diamond's size is measured by its diameter, which is the distance across the widest part of the diamond, known as the girdle. Therefore, a diamond with a larger girdle diameter will generally weigh more than a diamond with a smaller diameter, assuming all other factors are equal.

the weight of a diamond can be estimated based on its girdle diameter, and a full-cut round brilliant diamond with a 6.50 mm girdle diameter typically weighs around 1.00 carat. However, it's important to note that other factors, such as depth, cut, and clarity, can also affect a diamond's weight and value.

Step-by-step explanation:

The range of values for the correlation coefficient is - 1 to 1, inclusive is the correct answer.

Value is an important concept in economics, philosophy, and psychology. In economics, value is the amount of utility or satisfaction that an individual derives from a good or service. In philosophy, value is the worth or usefulness of something, based on its purpose. In psychology, value is the perceived importance of something that influences an individual's behavior. Value can also be seen as a measure of the worth of an object or action. Value is subjective and can differ from one person to another, depending on their beliefs and experiences. Value is also a key factor in decision-making and can help individuals make informed choices.

The range of values for the correlation coefficient is -1 to 1, inclusive. This means that the correlation coefficient can range from a perfect negative correlation (-1) to a perfect positive correlation (1).

Values in between those two extremes indicate a weaker correlation.

An expression for the measure  β° is 180 - x

The correct answer is an option (d)

We know that the sum of four angles of the quadrilateral is always 360°

In the attached quadrilateral angle A and angle D measures 90 degrees respectively.

The measure of ∠ABC in the figure is x° and the measure of ∠BCD is β°

From above statement for quadrilateral ABCD we have,

⇒ ∠A + ∠B + ∠C + ∠D = 360°

⇒ 90° + x°+ β° + 90° = 360°

⇒ x° + β° = 360° - 180°

⇒ x° + β° = 180°

⇒ β = 180 - x

Therefore, the required expression is β = 180 - x

Find the complete question below.

According to the question the median is most probably less than 36.

For a positively skewed distribution, the mode is the value that occurs most frequently, the mean is the average value, and the median is the middle value when the data is arranged in ascending order.

Given that the mode is \(\(x = 31\)\) and the mean is \(\(36\),\) we can infer that the majority of the data is clustered towards the left (lower values) and there are some relatively high values that pull the mean to the right.

Since the distribution is positively skewed, the median is expected to be lower than the mean. This is because the presence of outliers or higher values on the right side of the distribution affects the mean more than the median.

Therefore, the median is most probably less than 36.

Answer:

D. $27.59

Step-by-step explanation:

We know

Sinead bought 2 shirts for $15.03 each and a pair of shoes for $42.35.

15.03 x 2 = $30.06

So, 2 shirts cost $30.06

We find the total cost of the shirt and a pair of shoes by taking

30.06 + 42.35 = $72.41

If she paid for the items with a $100 bill, how much change did she receive?

100 - 72.41 = $27.59

So, the answer is D. $27.59

As x approaches negative infinity, both curves approach 0.  As x approaches positive infinity, both curves approach 0.

What are curves ?

In mathematics, a curve refers to a continuous and smooth line or path that may be straight or have various shapes and forms.

To sketch the region enclosed by the given curves \(y = 5x/(1 + x^2)\) and \(y = 5x^2/(1 + x^3)\), it is helpful to analyze the behavior of the curves and identify any intersection points.

First, let's find the intersection points by setting the two equations equal to each other:

\(5x/(1 + x^2) = 5x^2/(1 + x^3)\)

Next, we can cross-multiply and simplify:

\(5x(1 + x^3) = 5x^2(1 + x^2)\)

\(5x + 5x^4 = 5x^2 + 5x^4\)

Simplifying further:

\(5x - 5x^2 = 0\)

\(5x(1 - x) = 0\)

From this equation, we can see that there are two potential intersection points: x = 0 and x = 1.

Now, let's analyze the behavior of the curves around these points and their overall shape:

1. As x approaches negative infinity, both curves approach 0.

2. As x approaches positive infinity, both curves approach 0.

3. For x = 0, both curves intersect at the point (0, 0).

4. For x = 1, the first equation becomes y = 5/2, and the second equation becomes y = 5/2.

Based on this information, we can sketch the region enclosed by the curves as follows:

- The region is bounded by the x-axis and the curves \(y = 5x/(1 + x^2)\) and \(y = 5x^2/(1 + x^3)\).

- The curves intersect at the point (0, 0).

- The curves are symmetric about the y-axis.

- The curves approach the x-axis as x approaches positive and negative infinity.

The resulting sketch should show the curves intersecting at (0, 0) and the curves approaching the x-axis as x approaches infinity in both directions. Please note that without a graphing calculator or specific intervals provided, the sketch may not capture all the details of the curves, but it should provide a general understanding of the region enclosed by the curves.

The equation of the line is in slope-intercept form, y = mx + b, where m is the slope of the line and b is the y-intercept.

Comparing the given equation y = (-3/2)x - (5/4) with the slope-intercept form, we can see that the y-intercept is -5/4 and the slope of the line is -3/2.

Therefore, the slope of the line is -3/2.

The probability of selecting a heart and then a star with replacement is approximately 0.1875 or 18.75%.

Assuming that a standard deck of 52 playing cards is used, with 13 cards of each suit (including hearts) and 4 suits in total, the probability of selecting a heart on the first draw and then selecting a star (presumably meaning a card from a different suit) on the second draw with replacement is

P (heart than star)

= P (heart) × P (star)

= 13/52 × 39/52

= 507/2704

= 0.1875

where P (heart) is 13/52 is the probability of selecting a heart on the first draw (since there are 13 hearts in the deck), and P (star) is the probability of selecting a card that is not a heart on the second draw (since there are 39 non-heart cards left in the deck after the heart is replaced).

Therefore, the probability of selecting a heart and then a star with replacement is approximately 0.1875 or 18.75%.

-- The given question is incomplete, the complete question

"What is the probability of selecting a heart and then a star with replacement?" --

Answer:

Step-by-step explanation:

To solve this equation, we can start by using the logarithm property that states: log(a) - log(b) = log(a/b).

Then, we can apply this property to the left side of the equation:

log (7x+5) - log(x - 1) = log((7x+5)/(x - 1)) = 1

Next, we can rewrite the right side of the equation as:

log((7x+5)/(x - 1)) = log(7x+5) - log(x - 1) = 1

Now, we can use the inverse property of logarithms, which states: log(a) = b, then a = 10^b, to solve for x.

This gives us: (7x+5)/(x - 1) = 10

We can then cross-multiply and simplify to get: 7x+5 = 10x - 10

This equation simplifies to: 3x = -5

Dividing both sides by 3 gives us: x = -5/3

Therefore, the solution to the equation is x = -5/3.

Answer:144n Cubic units

Step-by-step explanation:

The volume of a prism is given by V = Bh, where B is the area of the base and h is the height of the prism. The volume of a cylinder is given by V = πr^2h, where r is the radius of the cylinder and h is its height. Since the prism and the cylinder have the same base area, we know that B = 247 square units for both shapes. We are given that the volume of the prism is 144π cubic units. We can use this information to solve for the height of the prism:

V = Bh

144π = 247h

h = 144π/247

Now we can use the height of the prism to find the radius of the cylinder, since the height of the cylinder is the same:

V = πr^2h

V = πr^2(144π/247)

V = (144π^2/247)r^2

We can now solve for the volume of the cylinder by substituting the given value of the prism's volume and solving for r^2:

144π = (144π^2/247)r^2

r^2 = 247/π

Finally, we can use this value of r^2 to find the volume of the cylinder:

V = πr^2h

V = π(247/π)(144π/247)

V = 144π

Therefore, the volume of the cylinder is 144π cubic units.
