hello

to solve this problem, we can simply use the formula of slope of a line

now we can identify our values

from the calculations above, the slope of the line from the given points is 0

Answer:

\(\boxed {\boxed {\sf y=2x+1}}\)

Step-by-step explanation:

Equations of line are written in slope-intercept form, or

\(y=mx+b\)

where m is the slope and b is the y-intercept. We know that the slope is 2 and the y-intercept is 1, because we are given:

\(m=2 \\b=1\)

Substitute the values into the formula.

\(y=2x+1\)

The equation of the line is y=2x+1

The store location for which  % of the data lies between $19,371.18 and $22.295.48 is location C

You should be aware that Standard deviation explains the relation of data with mean.

For normal distributions, 68% of the data lies under one SD from the mean. Two standard deviations is within  95%, and three standard deviations would take up to 99%.

This implies that on taking (mean + SD) and (mean - SD), 68% of data would cover these two numbers.

Add and subtract SD from the mean to check which location will give $19,371.18 and $22.295.48.

For location A, we have

M-SD=23,124.70-1553.43=21,571.27

M SD = 23,124.70 + 1,553.43 = 24,678.4

For location B, we have

M - SD = 24,842.18 - 1,617.20 = 23,224.98

M + SD = 24, 842.18 + 1,617.20 = 26,459.38

For location C, we have

M - SD = 20,833.33 - 1,462.15 = 19,371.18

M + SD = 20,833.33 + 1,462.15 = 22,295.48

This implies the store location is C

Step-by-step explanation:

Area of the patio is -6x² + x + 2 square yards and perimeter of the patio is 6 - 2x yards.

A yard is a unit of measurement used to measure length or distance in both the US customary system and the British imperial system. One yard is equal to 3 feet or 36 inches. In the US customary system, a yard is equal to 0.9144 meters, while in the British imperial system, it is equal to 0.9144 meters or 3 feet. Yards are commonly used for measuring larger distances, such as in construction or landscaping, as well as in some sports like American football and cricket.

The area of the rectangular patio is given by multiplying its length by its width, so the area is:

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

Now using distributive property we get,

A = 2 - 3x + 4x - 6x²

Simplifying further, we get:

A = -6x² + x + 2

Therefore, the area of the patio is described by the quadratic equation -6x² + x + 2.

To find the perimeter of the patio, we add up the lengths of all four sides. The length and width are given as (1 + 2x) and (2 - 3x), respectively, so the perimeter is:

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

Simplifying this expression, we get:

P = 2 + 4x + 4 - 6x

P = 6 - 2x

Therefore, the perimeter of the patio is described by the linear equation 6 - 2x.

1) The length of the rectangle is 15 feet and its width is 9 feet.

2) The admission price for an adult ticket is $10 and a student ticket is $6.

1) We shall use the formula for the area of a rectangle to find the length and the width:

A = l * w

where:

A = Area.

l = length

w = width.

Given:

l = 6 feet more than the width.

A = 135 feet square meter

First, we write an equation for the area like this:

(w + 6) * w = 135

Expanding the equation:

w² + 6w - 135 = 0

Next, solve the quadratic equation by factoring:

(w - 9)(w + 15) = 0

So either w - 9 = 0 or w + 15 = 0. This means that either w = 9 or w = -15. Since the width cannot be negative, we have w = 9.

Finally, we shall find the length since we know the width. This can be done by using the fact that it is 6 feet more than the width:

l = w + 6 = 9 + 6 = 15

So, the length is 15 feet and the width is 9 feet.

2) We can find the admission price for an adult ticket and a student ticket by using Mathematical operators:

Let,

a = an adult ticket price

s = a student ticket price

From the given information, we get these equations:

5a + 11s = 116

3a + 4s = 54

Next, solve by substitution.

Solving for 'a' in the second equation:

a = (54 - 4s) / 3

Then, substitute the second expression for 'a' into the first equation:

5((54 - 4s) / 3) + 11s = 116

Multiply both sides by 3:

5(54 - 4s) + 33s = 348

Finally, expand and simplify:

270 - 20s + 33s = 348

13s = 78

s = 6

So, a student ticket costs $6.

Plug this value into either equation to get the adult ticket price:

3a + (4 * 6) = 54

3a + 24 = 54

3a = 30

a = 10

So, an adult ticket costs $10.

Therefore,

1) The length of a rectangle is 15 feet and the width is 9 feet

2) The admission price for an adult ticket is $10 and that of a student is $6

The measure of the angle having the question mark, found using the law of sines is ? ≈ 140°

The law of sines states that the sine of an interior angle of a triangle is proportional to the the length of the side opposite to the angle.

The given parameters are;

The radius of circle A = 6.4

The radius of circle B = 4.0

The radius of circle C = 3.0

The measure of angle at C = 24°

The length of the segment AB = 6.4 + 4 = 10.4

According to the law of sines, we have;

\(\dfrac{sin(A)}{a} = \dfrac{sin(B)}{b} = \dfrac{sin(C)}{c}\)

Where;

a = The length of the side opposite angle ∠A

b = The length of the side opposite angle ∠B

c = the length of the side opposite angle ∠C

From the diagram, the side opposite angle ∠C, is AB, which by comparison indicates that when side c = AB = 10.4

c = 10.4

Similarly, the side opposite angle ∠A = a = BC = 4 + 3 = 7

a = 7

The known information are therefore; ∠C = 24°, a = 7, c = 10.4

\(\dfrac{sin(A)}{a} = \dfrac{sin(C)}{c}\)

\(\dfrac{sin(A)}{7} = \dfrac{sin(24^{\circ})}{10.4}\)

\(sin(A) = \dfrac{sin(24^{\circ})}{10.4}\times 7\)

\(\angle A = arcsine \left( \dfrac{sin(24^{\circ})}{10.4}\times 7\right)\)

∠A + ∠B + ∠C = 180° (angle sum property of a triangle)

∠B = 180° - (∠A + ∠C)

Which gives;

\(\angle B = 180^{\circ} -\left(24^{\circ} + arcsine \left( \dfrac{sin(24^{\circ})}{10.4}\times 7\right)\right) \approx 140^{\circ}\)

The measure of the angle is ∠B ≈ 140°

Step-by-step explanation:

Answer:

t = 15 / 20

Step-by-step explanation:

Given:

Distance traveled by Deon to ride a bicycle trail = 15 mile

Average speed of Deon to ride a bicycle trail = 20 mi/hour

Step-by-Step:

Let 'T' be the time taken to ride the bicycle trail.

We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.

\(Distance=\frac{Speed}{Time}\)

Distance = 15 miles

Speed = 20 miles / hour

Time = 15 / 20

Assuming time is t, the formula would be:

t = 15 / 20

"t = 15 mi/ 20 mi/hr " will help Deon calculate the time he will take.

The commission rate is 15%

Step-by-step explanation:

commission = commission rate x sales

where the commission rate is expressed as a decimal.

In this case, the salesperson earned a commission of $345 for selling $2,300 in merchandise. Therefore, we have:

345 = commission rate x 2300

To solve for the commission rate, we can divide both sides by 2300:

commission rate = 345/2300

Simplifying this expression, we get:

commission rate = 0.15

So, the commission rate is 15%

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

During 1 week an overnight delivery company found that the weights of its parcels were normally distributed, with a mean of 24 ounces and a standard deviation of 6 ounces.

Then the percent of the parcels weighed between 12 ounces and 30 ounces will be

When x = 12, then we have

z = (12 - 24) / 6

z = -2

When x = 30, then we have

z = (30 - 24) / 6

z = 1

Then we have

P(12 < x < 30) = P(-2 < z < 1)

P(12 < x < 30) = 0.81859

P(12 < x < 30) = 81.86%

Then the percentage of the parcels weighing more than 42 ounces will be

When x = 42, then we have

z = (42 - 24) / 6

z = 3

Then we have

P(x > 42) = P(z > 3)

P(x > 42) = 1 - P(z < 3)

P(x > 42) = 0.0013499

P(x > 42) = 0.13%
