The scatterplot that shows the strongest negative linear association would have the points on the plot in a downward slope from left to right. The closer the points are to forming a straight line going from the upper left to the lower right, the stronger the negative linear association is. The points on the scatterplot with the strongest negative linear association will be closely clustered along a line, indicating a clear and strong relationship between the two variables being plotted.

What is arithmetic?

Arithmetic is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots

Here, we have

Given: Tom has a water tank that holds 5 gallons of water. tell me this is water for my footing to fill six bottles they each hold 16 ounces and a picture that holds one over 2 gallons.

1 gallon = 128 ounces, 2 gallon = 256 ounces

6 bottles × 16 ounces = 96 ounces

2 gallon + 96 ounces = 256 + 96 ounces = 352 ounces

5 gallon = 5 × 128 = 640 ounces

= 640 - 352 = 288 ounces

To maximize the volume, of the rectangular prism, the carton should have dimensions of approximately 10.74 inches (length), 10.74 inches (width), and 5.37 inches (height).

Assuming the height of the rectangular prism is h inches.

According to the given information, the length and width of the prism will be twice the height, which means the length is 2h inches and the width is also 2h inches.

The total surface area of the rectangular prism is given by the formula:

Surface Area = 2lw + 2lh + 2wh

Substituting the values, we have:

576 = 2(2h)(2h) + 2(2h)(h) + 2(2h)(h)

576 = 8h² + 4h² + 4h²

576 = 16h² + 4h²

576 = 20²

h² = 576/20

h² = 28.8

h = √28.8

h = 5.37

The height of the prism is approximately 5.37 inches.

The length and width will be twice the height, so the length is approximately 2 * 5.37 = 10.74 inches, and the width is also approximately 2 * 5.37 = 10.74 inches.

Answer:

It sounds like a word problem! Let's solve it together. First, let's use some variables. Let's call the number of child tickets sold "c" and the number of adult tickets sold "a". We know that the total sales were $593.40, so we can write an equation for that:

6c + 9.9a = 593.4

We also know that twice as many adult tickets as child tickets were sold, so we can write another equation:

a = 2c

Now we can substitute the second equation into the first equation:

6c + 9.9(2c) = 593.4

Simplifying this equation, we get:

6c + 19.8c = 593.4

25.8c = 593.4

c = 23

So 23 child tickets were sold that day.

Answer:

The speed of the plane in the still air is 420 miles/hour

The speed of the wind 60 miles/hour

Step-by-step explanation:

Let the speed of the plane with the wind be v

Let the speed of the plane against the wind be u

Now, speed = distance/time

With the wind,

v = (1440 miles)/(3 hours) = 480 miles/hour

v = 480 miles/hour

Against the wind,

u = (1440 miles)/(4 hours) = 360 miles/hour

u = 360 miles/hour

Now, let the speed of plane be p, and speed of wind be w,

Now, with the wind, the speed is 480 mph,

so,

speed of plane + speed of wind = 480 mph

p + w = 480  (i)

and against the wind, the speed is 360 mph,

so,

speed of plane - speed of wind = 360mph

p-w = 360 (ii)

adding equations (i) and (ii), we get,

p+w + p-w = 480 + 360

2p = 840

p = 840/2

p = 420 miles/hour

Then, the speed of the wind will be,

p + w = 480,

420 + w = 480

w = 480 - 420

w = 60 miles/hour

The speed of the plane in still air is calculated to be 420 mph, and the speed of the wind is calculated to be 60 mph by solving the two simultaneous equations obtained from the time, rate, and distance relationship.

This problem is about the rate, time, and distance relationships. The rate at which the airplane travels in still air is r (unaffected by wind), and the speed of the wind is w. When the plane flies with the wind, it is 'assisted' and therefore travels faster - at a speed of (r + w); against the wind, it travels slower - at a speed of (r - w).

From the problem, we know that:

By solving these two equations, we get the following:

Adding these two gives 2r = 840 => r = 420 mph (the speed of the plane in still air), and subtracting gives 2w = 120 => w = 60 mph (the speed of the wind).

Answer:

Angles 2, 3 and 6,7 are acute angles

Answer:

∠2≅∠3

∠6≅∠7

∠3≅∠6

∠2≅∠7

Step-by-step explanation:

Hello There!

Acute angles have to have an angle that measures less then 90 degrees. This can simply be determine by looking at the angle and seeing if it makes a smaller angle or a larger angle

∠2 and∠3 are vertical angles which have congruent measures

∠6 and∠7 are also vertical angles

∠3 and∠6 are alternate interior angle which are can be known for being congruent

∠2 and ∠7 are alternate exterior angles which are also congruent

so angles 2, 3, 6 and 7 are all congruent

a) If t is a real variable, then the line through the endpoints of p and q is

(p - q) t + p

That is, p - q is the vector pointing from the tip of q to the tip of p (recall the "triangle law" for vector addition). Then (p - q) t is a line through the origin parallel to p - q. Adding p to this line translates it so that it will pass through p.

So one formulation of the line's equation is

r(t) = ((3, -1, 1) - (7, 1, 3)) t + (3, -1, 1)

… = (-4, -2, -2) t + (3, -1, 1)

… = (-4t + 3, -2t - 1, -2t + 1)

which is identical to the equation you found, with t = -k.

b) OA is the line segment connecting the origin O and the point A on the line we found in part (a).

a is then the vector pointing from the origin to A. If OA is perpendicular to the line, then the dot product of a with the direction vector p - q must be zero.

a • (p - q) = 0

(a₁, a₂, a₃) • (-4, -2, -2) = 0

-4a₁ - 2a₂ - 2a₃  =0

2a₁ + a₂ + a₃ = 0

Let s(t) denote the line containing a. Then

s(t) = (a₁, a₂, a₃) t

r(t) and s(t) intersect exactly once for some value of t such that

(a₁, a₂, a₃) t = (-4, -2, -2) t + (3, -1, 1)

(a₁ + 4, a₂ + 2, a₃ + 2) t = (3, -1, 1)

Now we solve for the components of a such that the conditions we found are all met:

\(\begin{cases}2a_1 + a_2 + a_3 = 0 \\ (a_1 + 4)t = 3 \\ (a_2 + 2)t = -1 \\ (a_3 + 2)t = 1\end{cases}\)

and you would find the two lines intersect when t = 1/2, and so

a = (2, -4, 0)

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.

The cumulative probability is

P(at most 2 ) = 0.187560896 [answer]

a)

Note that the probability of x successes out of n trials is

P(n, x) = nCx p^x (1 - p)^(n - x)

where

n = number of trials = 12

p = the probability of a success = 0.33

x = the number of successes = 3

Thus, the probability is

P ( 3 ) = 0.21509867 [answer]

You can afford to purchase 4054 lemons with $15 at the rate of 0.37 cents per lemon

From the question, we have the following parameters that can be used in our solution:

Amount invested = $15

Unit rate of lemon = 0.37 cent

Convert cent to dollars ($)

So, we have

Unit rate of lemon = $0.0037

From the above parameter, we can calculate the number of lemon using the following formula of unit rate

The unit rate is calculated as

Unit rate = Amount invested/Number of lemons

This gives

Number of lemons = Amount invested/Unit rate

Substitute the known values in the above equation

So, we have the following equation

Number of lemons = 15/0.0037
