-0.21

Step-by-step explanation:

The solution is, -0.21 , is the most likely the correlation coefficient for the set of data shown.

A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution.

here, we have,

From the scatter plot that is shown in the graph above, we can observe that the set of data represented are not clustered far apart from each other along the line of best fit.

This suggest a correlation coefficient of lesser value close to zero which shows weaker correlation between variables.

Also, we can observe that There's a downward slope signifying a negative relationship.

As one variable increases, the other variable decreases.

Therefore the correlation coefficient that will match the set of data shown is -0.21.

Answer:

David made $18

Step-by-step explanation:

Leslie made $10. This means that you take 46-10=36

Chen-Chen made twice as much as David so 36/2=18 So Chen made $9.

David- 36-18= 18 So, David made 18 dollars.

In this mathematics problem, David, Chen, and Leslie together raised $46, with Leslie raising $10. Given that Chen raised twice as much as David, we can represent David's earnings as 'x' and Chen's as '2x'. By solving the resulting equation 3x = $36, we find that David raised $12.

To find out how much David made in the walk-a-thon, we need to break down the information given. We know that all three individuals together made $46, with Leslie making $10. So, David and Chen together made $46 - $10 = $36. But we are also told that Chen made twice as much as David. If we represent David's earnings as 'x', then Chen's earnings would be '2x'. Therefore, 2x (Chen's earnings) + x (David's earnings) equals $36.

Adding 2x and x gives 3x, so the equation to solve is 3x = $36. To solve for 'x', divide both sides of the equation by 3. This gives x = $36 / 3, so David's earnings, represented by 'x', is $12.

Dmitri needs 854 glass tiles to cover the top and sides of the box.

Given the dimensions of the box, where Length (L) = 13 cm, Width (W) = 20 cm, and Height (H) = 9 cm, we can find the surface area of the box using the formula for the surface area of a cuboid:

[tex]\[ \text{Surface Area} = L \times W + 2 \times L \times H + 2 \times W \times H \][/tex]

Substitute the values:

[tex]\[ \text{Surface Area} = 13 \times 20 + 2 \times 13 \times 9 + 2 \times 20 \times 9 \][/tex]

[tex]\[ \text{Surface Area} = 260 + 234 + 360 \][/tex]

[tex]\[ \text{Surface Area} = 854 \, \text{cm}^2 \][/tex]

Now, since each glass tile is 1 cm square, the number of tiles needed is the total surface area divided by the area of each tile:

[tex]\[ \text{Number of tiles} = \frac{\text{Surface Area}}{\text{Area of one tile}} \][/tex]

[tex]\[ \text{Number of tiles} = \frac{854}{1} \][/tex]

[tex]\[ \text{Number of tiles} = 854 \][/tex]

Therefore, Dmitri needs 854 glass tiles to cover the top and sides of the box.

Answer:

The correct answer is D.

By applying the theorem of intersecting chord to this circle, the measure of arc XY is: D. 137°.

In Mathematics and Geometry, the theorem of intersecting chord states that when two (2) chords intersect inside a circle, the measure of the angle formed by these chords is equal to one-half (½) of the sum of the two (2) arcs it intercepts.

By applying the theorem of intersecting chord to this circle shown in the image attached above, we can logically deduce that the measure of arc XY can be calculated by using this formula:

m∠ZWV = 1/2 × (Arc XY + Arc ZV)

90° = 1/2 × (Arc XY + 43)

180° = Arc XY + 43

Arc XY = 180 - 43°

Arc XY = 137°

Answer:

Option D. $29,647

Step-by-step explanation:

The following were obtained from the question:

Present value = $75,000

Rate of depreciation (R) = 6%

Time (t) = 15 years

Amount after 15 years =?

Since the worth of the tractor is depreciating, we shall apply the following formula to obtain the worth after 15 years:

Amount = present value x (1 – R)^t

Amount = $75000 x (1 – 6%)^15

Amount = $75000 x (1 – 0.06)^15

Amount = $75000 x (0.94)^15

Amount = $29647

Therefore, the value of the tractor after 15 years is $29647

Final answer:

The equation of the third rocket is likely referring to the Tsiolkovsky rocket equation Δv = ve · ln(mo/m), which calculates the change in velocity of a rocket by considering the expelled fuel mass, exhaust velocity, and the rocket's initial and final mass.

Explanation:

The equation of the third rocket is not explicitly provided in the question, but we can infer it relates to the Tsiolkovsky rocket equation which describes the motion of a rocket. This rocket equation is fundamental in understanding how rockets achieve motion through the expulsion of fuel mass at a high speed, thereby increasing their velocity. This change in velocity Δv is the result of the thrust imparted by the propellant's mass expulsion and is calculated using the equation: Δv = ve · ln(mo/m), where Δv is the change in velocity, ve is the effective exhaust velocity, mo is the initial total mass, and m is the final total mass of the rocket.

From the information provided, we can use the rocket's mass flow rate and the given velocity function to integrate and determine the rocket's position over time. When the thrust ends at t3 = 4.0 s, the position formula r(t) involves the integration of the velocity function, resulting in a function of time with an integration constant D.

The physical principle behind all rocket propulsion is Newton's third law of motion. The motion of the rocket is also described by factors such as the exhaust velocity, rate of fuel expulsion, and the total mass. To maximize acceleration, the non-fuel mass of the rocket must be minimized, enabling the spacecraft to achieve the necessary velocities for space missions.

Answer:

Step-by-step explanation:

To get the number of level truck loads needed to remove all the dirts in the house, first we need to calculate volume of the truck and the house.

Volume of truck = Length * Breadth * Height

If the truck is 5.0 for the length 2.0 for the height 3.0 for the side base;

Volume of the truck = 5*2*3

Volume of truck = 30

For the house;

Volume of house = Length * Breadth * Height

If the house is 4.0 for the height 14.5 for the length and 11.0 for the side base, then

Volume of the house = 4*14.5*11 = 638

Number of level truck loads needed to remove all the dirts = Volume of house/Volume of the truck = 638/30 ≈ 21.3

This means that about 21 level truck loads are necessary to remove all dirts.

Final answer:

To find the number of truck loads needed to remove all the dirt excavated for the house, calculate the volume of dirt excavated and divide by the volume the truck can carry. In this case, approximately 11 truckloads are required.

Explanation:

The number of level truck loads needed to remove all the dirt can be calculated by first finding the volume of dirt excavated for the house and then dividing it by the volume the truck can carry.

Volume of dirt excavated for the house = 15 m x 11 m x 1 m = 165 m3

Number of truck loads = Volume of dirt excavated / Volume truck can carry

Number of truck loads = 165 m3 / 15 m3 = 11 truck loads

Answer:

The answer is part B

Step-by-step explanation:

The equation given is y = 4500 - 450p

y is the no of demand units

p is the price

let price be 1 dollar.

Therefore,

y = 4500 - 450x1

y = 4050

Now, let the price be 2 dollars.

y = 4500 - 450x2

y = 3600

Subtract the two values and the answer is 450.

This means that for each dollar increased, the no of demand units falls by 450
