Answer: x<4

Step-by-step explanation:

19>15+x

4>x

x<4 is the answer

Answer:

Since 15+x is less than 19. 15+x cannot equal to or greater than 19. If x is greater or equal to 4, the answer will be equal to or greater than 19 which is not true for the equation shown above.

So x is less than 4.

The resulting equation is (x-2) (x+2)-1(3x) = (x-3) (x-2).

The lowest integer that unites all of the fractions in a given collection is known as the least common denominator (LCD).

Given that,

The equation x+2/3x - 1/x-2 = x-3/3x is being multiplied by the least common denominator (LCD)

So, further solving this equation,

x+2 / 3x - 1/x-2 = x-3/3x

Here, the least common denominator (LCD) is (3x)(x-2). so we multiply the whole equation by the least common denominator (LCD).

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

We multiply each term by the least common denominator (LCD).

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

Thus, we get (x-2) (x+2)-1(3x) = (x-3) (x-2).

Therefore,The resulting equation is (x-2) (x+2)-1(3x) = (x-3) (x-2).

Answer:

Step-by-step explanation: answer is d

The probability of getting exactly 14 heads by flipping a fair coin 20 times is 0.03696.

The number of times a fair coin is flipped = 20

The outcomes for flipping the coin once = 2

Therefore, the outcomes for flipping the coin 20 times = (2) ^ 20

Number of heads needed = 14

The number of ways of getting exactly 14 heads = 20C14

20C14 is the 20! / (14! (20-14)! = 38760

Probability of getting an event = possible outcome / total outcomes

Thus, the probability of getting exactly 14 heads by flipping a fair coin 20 times = (20C14) / (2 ^ 20) ≈ 0.03696

The area of the trapezium is 36.3 unit squared.

The figure above is a trapezium. Therefore, the area of a trapezium can be represented as follows:

Hence,

area of a trapezium = 1 / 2 (a + b)h

where

Therefore,

area of a trapezium = 1 / 2 (a + b)h

where

Using Pythagoras's theorem,

c² = a² + b²

where

h² = 6² - 1.5²

h²= 36 - 2.25

h = √33.75

h = 5.80947501931

h = 5.81

Therefore,

area of the trapezium = 1 / 2 (4 + 8.5)5.8

area of the trapezium = 1 / 2 (12.5)5.8

area of the trapezium = 72.5 / 2

In circle A,  angle RAS is 74 degrees and  angle RTB is 28 degrees. The measure of minor arc BR is 81 degrees.

The figure is in the attached picture.

Notice that:

AS = AR = radii of the circle.

Hence, triangle SAR is an isosceles triangle, and ∠ASR = ∠ARS.

The sum of angles in a triangle is  180°.

Therefore,

∠ARS +  ∠ASR+ 74° =  180°

Since ∠ASR = ∠ARS,

2∠ARS + 74° =  180°

2∠ARS  = 106°

∠ARS  =  53°

and

∠ASR = ∠ARS = 53°

Angle in a straight line:

∠AST  + ∠ASR =  180°

∠AST   =  180° - ∠ASR =  180° - 53°  =  127°

Refer to triangle SAT:

∠SAT  =  180° - 28° - 127°  =  25°

The measure of minor arc BR = ∠RAB

∠RAB  =  180° - 74° - 25°

Use law of cosines to find angles A, B, and C. Angle A = X°, B = Y° and C = Z°.

What is triangle ?

A triangle is a polygon with three sides and three angles. The sum of the three angles in a triangle always equals 180 degrees. Triangles can be classified based on the length of their sides or the measure of their angles.

We can use the law of cosines to find the angles. The law of cosines states that for any triangle, the square of one side length is equal to the sum of the squares of the other two side lengths, minus twice the product of the other two side lengths multiplied by the cosine of the angle opposite the first side.

Let A, B, and C be the angles opposite the sides of length 114 meters, 70 meters, and 95 meters, respectively.

We can use the following equation to find angle A:

cos A = (70^2 + 95^2 - 114^2) / (2 * 70 * 95)

Once we have the value of cos A, we can use the inverse cosine function to find the angle A in degrees.

Similarly, we can use the same formula to find the angle B and C.

cos B = (114^2 + 95^2 - 70^2) / (2 * 114 * 95)

cos C = (114^2 + 70^2 - 95^2) / (2 * 114 * 70)

Use law of cosines to find angles A, B, and C. Angle A = X°, B = Y° and C = Z°.

The equation of the line would be y = 17/7x + 1.

What is the equation of the line?

The equation of a line is a mathematical expression that describes the position of a line in a coordinate plane. It typically takes the form of "y = mx + b", where "m" is the slope of the line and "b" is the y-intercept, the point where the line crosses the y-axis.

The whole question is:

Write an equation of the line passing through the point (8,7) that is perpendicular to the line  [tex]y + 7 = -\frac{7}{17}(x+8)[/tex]

To write the equation of a line that is perpendicular to a given line, we can use the slope of the given line and the point the new line passes through.

The slope of the line [tex]y + 7 = -\frac{7}{17}(x+8)[/tex] can be found by isolating y and then taking the derivative, which gives us: -7/17.

The slope of a line perpendicular to this line is the negative reciprocal of the given line's slope, which is 17/7.

We also know that the new line passes through the point (8,7). Using a point-slope form of a line which is (y-y1) = m(x-x1) where m is the slope, we can write the equation of the line as:

y - 7 = 17/7(x - 8)

So the equation of the line that passes through the point (8,7) and is perpendicular to the line [tex]y + 7 = -\frac{7}{17}(x+8)[/tex] is:

y = 17/7x + 1

Hence, the equation of the line would be y = 17/7x + 1.

If the mean of a set of data is 4.11 and its standard deviation is 3.03. the z score for a value of 10.86 is: 2.23.

Using this formula to find the z-score

Where:

Value = 10.86

Mean = 4.11

Standard deviation = 3.03

Let plug in the formula

z-score  =  10. 86 - 4.11 / 3.03

Answer:

1. To find the gradient of a line, we can use the slope-intercept form of the equation: y = mx + b, where m is the gradient and b is the y-intercept.

a) To find the gradient of (x+7)/(y-2) = 0, we can first rewrite the equation as y = (2x+14)/(x+7). To find the slope, we can take the derivative of y with respect to x. We get the slope or the gradient of the line as m = 2/(x+7).

b) To find the gradient of the line through (p,5) and (6,2p), we can use the point-slope form of the equation: y - y1 = m(x - x1). We can substitute the coordinates of the two points and solve for m.

y - 5 = m(x - p)

2p - 5 = m(6 - p)

2p - 5 = 6m - mp

mp + 6m = 2p + 5

m(p+6) = 2p + 5

m = (2p+5)/(p+6)

2. To find the equation of a line, we can use the slope-intercept form of the equation: y = mx + b, where m is the gradient and b is the y-intercept.

a) To find the equation of the line with a gradient of 3, passing through (0,5), we can substitute the values into the slope-intercept form.

y = 3x + b

5 = 3(0) + b

b = 5

The equation of the line is y = 3x + 5

3. To find the value of p, if the gradient of the line joining (-1,p) and (p, 4) is 2/3, we can use the point-slope form of the equation: y - y1 = m(x - x1). We can substitute the coordinates of the two points and the gradient, and solve for p.

y - p = (2/3)(x - (-1))

4 - p = (2/3)(p - (-1))

4 - p = (2/3)p + (2/3)

(2/3)p - 4 + p = (2/3)

p = 6

Final Answer: The value of p is 6.

The profit per foot of the satin ribbon that the craft store buys and sells is $0.80.

The profit generated by the craft store per foot is determined by reducing the transactions to their unit cost and price.

The profit per unit becomes the difference between the unit selling price and the unit cost.

In other words, the profit per unit is the unit rate (per-unit profit) or ratio obtained as a difference between two unit parameters.

The cost of buying 150 feet of satin ribbon = $13.50

The unit cost per foot = $0.09 ($13.50/150)

The sales price for 5 feet = $0.80

The unit selling price per foot = $0.16 ($0.80/5)

The profit per unit = $0.80 ($0.16 - $0.80)
