The area of the triangle is  10.825 square feet.

The area of a triangle is the measure of the region enclosed by the three sides of the triangle. It is expressed in square units and can be calculated using various formulas, such as the formula for the area of a triangle using its base and height (A = (1/2)bh),

To find the area of the triangle, we can use Heron's formula, which states that the area of a triangle with sides of length a, b, and c is given by:

A = √(s(s-a)(s-b)(s-c))

where s is the semi perimeter of the triangle, given by:

s = (a + b + c)/2

Here, the sides of the triangle are 4 ft, 3 ft, and 2/3 ft. Therefore, the semi perimeter is:

s = (4 + 3 + 2/3)/2 = 3 2/3 ft

Using Heron's formula, the area of the triangle is:

A = √(3 2/3(3 2/3 - 4)(3 2/3 - 3)(3 2/3 - 2/3))

A = √(3 2/3(2/3)(9/3)(9/3 - 2/3))

A = √(3 2/3(2/3)(9/3)(8 1/3))

A = √(3 2/3(2/3)(3)(25/3))

A = √(323×25)/3

A = √(450)/3

A ≈ 10.825 ft²

Therefore, the area of the triangle is approximately 10.825 square feet.

A positively skewed distribution is due to an extremely large number.

A positively skewed distribution is a type of distribution in which the majority of the data values are clustered towards the left side of the distribution, with a tail extending to the right. This means that there are relatively more smaller values in the dataset than larger values. In a positively skewed distribution, the mean of the dataset is typically larger than the median, and the mode may not be a good representation of the central tendency of the data. This is because the presence of a long tail on the right-hand side of the distribution pulls the mean towards the higher values, while the median remains closer to the center of the dataset. Some common examples of positively skewed distributions include income distributions, where there are a few extremely high earners that skew the data towards the right, and test scores, where there may be a few students who perform extremely well and pull the average higher than the median.

Here,

A positively skewed distribution occurs when the tail of the distribution extends to the right, and the majority of the data is clustered towards the left side of the graph. This means that there are relatively more smaller values in the dataset than larger values. One common cause of positive skewness is the presence of extremely large values, also called outliers, in the dataset. These large values pull the mean of the dataset towards the right, resulting in the tail of the distribution stretching in that direction.

Therefore, out of the options provided, the correct answer is "an extremely large number."

The points on the y-axis are on the line that passes through point R and is parallel to line PQ (0, 2/3). Option A is correct.

Given that,
On a coordinate plane, line P Q goes through (negative 3, negative 3) and (3, negative 1). Point R is at (1, 1).

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope of the line PQ,
m = -1 + 3 / 3 + 3
m = 1/3

The equation of the line passes through point R and parallel to line PQ,
y - 1 = m {x - 1}
y - 1 = 1/3x - 1/3
y = x / 3 - 1/3 + 1
y = x/3 +2/3

Using the information provided, it appears that your neighbor will not save money by picking up the soil himself as its total cost is $103.86 as opposed to cost of delivery $30.

Here is a detailed breakdown of the calculations and assumptions made:

The area of the yard is estimated to be around 7,200 sq.ft. Assuming a 4 inch layer of topsoil, this requires 4 cubic yards (1 cubic yard = 27 cubic feet).

The cost of the soil delivery is $30 per truckload (up to 18 cubic yards). So the delivery cost for 4 cubic yards of soil would be $30.

The cost of topsoil per cubic yard is $18. Thus, the total cost of the topsoil is $72.

The weight of topsoil is 2000 pounds per cubic yard, so the total weight of the soil is 8,000 pounds (4 cubic yards x 2000 pounds).

The pickup truck's payload capacity is 1800 pounds, so the truck can only transport 1/4 of the total weight of the soil (1800/8000 = 0.225). Thus, it would require 4 trips to transport the soil, and the total trip distance is 36 miles (9 miles x 4 trips).

The truck gets 17 miles per gallon, so it would require 2.1 gallons of gas for each trip (36 miles/17 mpg = 2.12). The total amount of gas needed for the 4 trips is 8.4 gallons (2.1 gallons x 4 trips). The cost of gas per gallon is assumed to be $3.79, so the total cost of gas for the 4 trips is $31.86.

Thus, the total cost of picking up the soil himself is $31.86 + $72 = $103.86. This is higher than the cost of delivery which is only $30, so it would be better to pay for delivery.

To conclude, your neighbor will not save money by picking up the soil himself, and it is recommended that he pays for delivery.

Note: The question is incomplete. The complete question probably is: He has decided to remove all the old sod (grass), bring in a new 4 inch layer of topsoil, install new in-ground sprinklers, and reseed the lawn. He seems to think that he'll be able to save money by hauling loads of topsoil from the store himself in his pickup truck, rather than paying for delivery, but I don't think he's right. You're going to help us settle this. Here is (most of) the information you asked for:

Using this information, figure out whether my neighbor will save money by picking up the soil himself. Use the results of your calculations to guide your decision: would you recommend that my neighbor pick up the soil himself, or pay for delivery?

Answer:

In geometry, a transformation is an operation that moves, flips, or changes a shape (called the preimage) to create a

new shape (called the image). A translation is a type of transformation that moves each point in a figure the same

distance in the same direction. Translations are often referred to as slides. You can describe a translation using words

like "moved up 3 and over 5 to the left" or with notation. There are two types of notation to know.

1. One notation looks like T(3, 5). This notation tells you to add 3 to the x values and add 5 to the y values.

2. The second notation is a mapping rule of the form (x, y) → (x−7, y+5). This notation tells you that the x and

y coordinates are translated to x−7 and y+5.

Answer:

132 people bought balcony seats and 450 people bought ground seats.

Step-by-step explanation:

We want to solve the system of equations:

\(\left\{ \begin{array}{ll} 15b+10g=6480 \\ b+g=582 \end{array} \right\)

We can solve this by using substitution. From the second equation, we can subtract b from both sides:

\(g=582-b\)

In the first equation, we can divide both sides by five:

\(3b+2g=1296\)

Substitute:

\(3b+2(582-b)=1296\)

Distribute:

\(3b+1164-2b=1296\)

Simplify:

\(b+1164=1296\)

Solve for b:

\(b=132\)

Using the modified equation again, substitute:

\(g=582-(132)\)

Evaluate:

\(g=450\)

Therefore, 132 people bought balcony seats and 450 people bought ground seats.

Answer:

First part: 0.35 miles per minute

Second part: 3.5 miles in 10 minutes

Step-by-step explanation:

Think about this as a fraction. Fractions can't be added nor subtracted unless they share the same denominator. So for this case, we have to turn hours into minutes. So 21 mph becomes 21 miles per 60 minutes. Then, we divide 60 from each side to find the speed per minute. 21/60 = 0.35, so the answer to the first part is 0.35 miles per minute.

Using what we got, we can answer the second part of the distance covered in 10 minutes. So, we just multiply 0.35 by 10 which is 3.5 miles covered in 10 minutes.

The operation you would use to solve \(6y=10\) is division because we want to get the variable by itself. We use division because it' is the inverse of multiplication. So to solve \(6y=10\), I would be dividing.

\(6y=10\)

Divide both sides by 6(get the variable by itself):

\(\dfrac{6y}{6} =\dfrac{10}{6}\)

\(=1.666667\)

The standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin is:

\(y=-\frac{1}{3}x^{2}\)

What is the equation of the parabola with a vertex at the origin and a vertical axis, which passes through the point (-3, -3)?

The equation of the parabola in standard form is \(y=-\frac{1}{3}x^{2}\). This equation represents a parabola with a vertex at the origin (0, 0) and a vertical axis. Additionally, it passes through the point (-3, -3), satisfying the given characteristics.

To find the standard form of the equation of a parabola with a vertex at the origin and a vertical axis, we can use the general equation of a parabola:

y=\(a(x-h)^{2}\)+k

where (h, k) = the vertex of the parabola.

Since the vertex is at the origin , the equation becomes:

y=a\(x^{2}\)

Now, we need to find the value of 'a' using the given point on the parabola (-3, -3).

These values are satisfied the equation, we have:

\(-3=a(-3)^2\)

Simplifying:

−3=9a

Dividing both sides by 9:

\(a=-\frac{1}{3}\)

Therefore, the standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin is:

\(y=-\frac{1}{3}x^{2}\)

In a given case where two suppliers, A and B where 8 out of 200 chips from supplier A and 13 out of 250 chips from supplier B is defective, there is not enough evidence to show that the two suppliers are different.

Considering sample from supplier A, the proportion of defective chip, p^a = 8/ 200 = 0.04

And the sample size, n = 200

Considering sample from supplier B, the proportion of defective chip, p^b = 13/250 = 0.052

And sample size, m = 250

To know whether the two suppliers are different we calculate a two-sided confidence interval for pA − pB. There is no proof that the two population proportions differ if the confidence interval comprises 0, which indicates that pA = pB.

Let us consider a confidence interval of 95%, α = 0.05. Null hypothesis, H0 : pA = pB and alternate hypothesis H1 : pA ≠ pB.

p^a − p^b = 0.04 - 0.052 = -0.012

A pooled estimate of the common success probability, p^

p^ = (8 + 13)/ (200 + 250)

= 21/ 450

= 7/ 150

≈ 0.047

Thus, the z-statistic can be obtained by

z = (p^a − p^b)/ (p^ × (1 - p^) × (1/ n + 1/m))⁽⁰.⁵⁾

= -0.012/ √(0.047 × (1 - 0.047) × (1/200 - 1/250))

= -0.600

Also, zα/2 = 1.960

The two-sided confidence interval for pA − pB is

8/ 200 − 13/ 250 ± 1.960 ×√(8×(200−8)/ 200³ + 13×(250−13)/ 250³

= (−0.051, 0.027)
