A statement that must be true according to the dot plot include the following: A. the data is skewed left and shows that on half of the days, Darren received 11 or 12 e-mails from the customer.

In Mathematics, a dot plot can be defined as a type of line plot that is typically used for the graphical representation of a data set above a number line, especially through the use of dots.

By critically observing the given dot plots which is used to illustrate the number of e-mails that Darren received from one of his customers each day for 14 days, we can reasonably infer and logically deduce that the data set is skewed left, which ultimately implies that that on half of the days (7 days), Darren received a total of 11 or 12 e-mails from this customer.

In conclusion, the dot plot is skewed left because it has a long tail on its left side and 7 days is the half of 14 days.

Step-by-step explanation:

You put the open part of the symbol towards the bigger number because it is greater.

They are not equal so you would not use the equal sign.

Answer:

1. 25/18 ft³

2. 1/216 ft³

Step-by-step explanation:

So all we need to do to calculate the volume is multiply each length gollowing the formula: V= S1×S2×S3

so that being said we transform each unit into sixth parts:

6/6 ft×5/6 ft× 10/6ft.

so we multiply the numerators and denominators, leaving us with 300/216 ft³ (ft×ft=ft², ft×ft×ft=ft³)

if we simplify by dividing both factors by 12, because that is the same result ( 3/6 is the same as 1/2) and we are left with 25/18 ft³

So that is answer 1

Answer 2, because we already have 300/216, that is the full prism, we just divide it by the number of cubes there are, and that is 300.

We are left with 1/216.

I hope this was helpful.

In this scenario, we have a uniformly charged thin rod extending along the x-axis from the origin (x = 0) to positive infinity (x = +∞).

The term "uniformly charged" means that the charge is distributed evenly throughout the entire length of the rod.

To analyze this situation, we can consider the following steps: 1. Determine the linear charge density (λ) of the rod. Since the rod is uniformly charged, λ remains constant along its entire length. λ is usually given in units of charge per length (e.g., coulombs per meter).

2. To find the electric field at a particular point along or outside the rod, we can break the rod into infinitesimally small segments (dx) and consider the contribution of the electric field (dE) from each of these segments.

3. Calculate the electric field (dE) produced by each segment at the desired point using Coulomb's equations , considering the linear charge density (λ) and distance between the segment and the point.

4. Integrate the electric field contributions (dE) from all segments along the entire length of the rod (from x = 0 to x = +∞) to find the total electric field (E) at the point of interest.

By following these steps, you can analyze the electric field and related properties of a uniformly charged thin rod extending along the x-axis from x = 0 to x = +∞.

T/F Solution that can be analytically obtained but is not an actual answer to the equation often due to restrictions in the type of function such as a negative in the log

This statement is true.

Because, Sometimes, when solving an equation using analytical methods, we may arrive at a solution that is mathematically correct but is not a valid answer due to the restrictions in the type of function used.

For example, if a negative value appears in the logarithmic function, the solution may not be valid because the logarithmic function is only defined for positive values.

In such cases, we need to go back and recheck our work and take into account the restrictions of the function to arrive at a valid solution.

Sometimes when solving an equation analytically, the resulting solution may not be a valid answer due to restrictions in the domain of the function.

For example, if we solve an equation involving a logarithmic function, we may end up with a negative value inside the logarithm, which is not defined for real numbers. In such cases, the solution obtained analytically is not a valid answer to the equation.

Another example is when solving for the roots of a quadratic equation using the quadratic formula, we may obtain complex solutions even though we are only interested in real solutions.

Thus, it is important to always check the solutions obtained to ensure that they satisfy any domain or range restrictions of the functions involved in the equation.

Answer:

Step-by-step explanation:

Given the height of the ball modelled by the equation h(t)=16t²+84 after t secs. At the maximum height, the velocity of the ball is zero.

Velocity V is the change of rate of displacement.

V = dh/dt = 32t

0 = 32t

t = 0secs

at t = 0;

h(0) = 16(0)²+84

h(0) = 84feet

This shows that the maximum height of the ball is 84feet

Answer:

5+(-9)=14

Step-by-step explanation:

Answer:

14 and 23

Step-by-step explanation:

To find two arithmetic means between 5 and 23, we need to first find the common difference between consecutive terms.

The common difference (d) between consecutive terms in an arithmetic sequence can be found using the formula:

d = (an - a1) / (n - 1)

where a1 is the first term, an is the last term, and n is the number of terms.

In this case, a1 = 5, an = 23, and n = 3 (since we want to find two means, there will be a total of 4 terms in the sequence). Plugging these values into the formula, we get:

d = (23 - 5) / (3 - 1) = 9

So the common difference between consecutive terms is 9. To find the first mean, we add the common difference to the first term:

First mean = 5 + 9 = 14

To find the second mean, we add the common difference to the first mean:

Second mean = 14 + 9 = 23

Therefore, the two arithmetic means between 5 and 23 are 14 and 23.

Step-by-step explanation:

To prove that triangle ABC is congruent to triangle DCB, we can use the Angle-Side-Angle (ASA) postulate.

The ASA postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

In this case, we are given that angle ABC is congruent to angle DCB. This is one angle that is shared by both triangles.

Next, we need to identify another angle that is congruent between the two triangles. Looking at the given information, we can observe that angle B is common to both triangles ABC and DCB. Therefore, angle B is congruent to itself.

Lastly, we need to identify the included side, which is the side that is between the two given angles. In this case, side BC is the included side.

Thus, we have shown that angle ABC is congruent to angle DCB, angle B is congruent to angle B, and side BC is shared by both triangles.

By fulfilling the conditions of the ASA postulate (two congruent angles and the included side), we can conclude that triangle ABC is congruent to triangle DCB.

Therefore, the ASA postulate can be used to prove that ABC = DCB, demonstrating the congruence between the two triangles based on the given information.

y = -3/2x - 20.5 is the line crossing through (-7,10) perpendicular to 2x - 3y= -3

In an equation, parallel lines have the opposite reciprocal slope. In other words, if a line's slope is a positive fraction, its reciprocal slope is negative.

Here given that  2x - 3y= -3

can also be written as

y = 2/3x + 1

Here 2/3 is the slope and 1 is the y-intercept

To find a parallel line to the following equation, use the opposite reciprocal slope and point, then solve using the point-slope formula.

y - y₁ = m(x - x₁)

We have, m = -3/2,  x₁ = -7 and y₁ = 10

y - 10 = -3/2(x - (-7))

y - 10 = -3/2(x + 7)

y - 10 = -3/2x - 21/2

Answer:0.5j^27+3j+168.45

Step-by-step explanation: I used a calculator

The area under the curve to the right of 64 is 0.2514.

To find the area under the curve to the right of 64 in a normal distribution with mean μ = 60 and standard deviation σ = 6, follow these steps:

1. Calculate the z-score: z = (x - μ) / σ, where x = 64.
  z = (64 - 60) / 6
  z = 4 / 6
  z ≈ 0.67

2. Use a z-table or calculator to find the area to the left of z = 0.67.
  The area to the left of z = 0.67 is approximately 0.7486.

3. Subtract the area to the left from 1 to find the area to the right of z = 0.67.
  Area to the right = 1 - 0.7486
  Area to the right ≈ 0.2514

So, the area under the curve to the right of 64 in this normal distribution is approximately 0.2514.

Answer:

3 pizzas

Step-by-step explanation:

First, we can calculate how many slices are necessary. Each person wants two slices, so for each person, we must add 2 slices. We can add 2 15 times, or multiply 2 by 15 to get 2 * 15 = 30

We now know that we need 30 slices of pizza. Next, we need to figure out how many pizzas we need given this information.

For each pizza, we can add 10 slices, as there are 10 slices of pizza.

For the first pizza, we have 10 slices

For the second, we have 10+10 = 20 slices

For the third, we have 10+10+10 = 10 * 3 = 30 slices. Perfect!

Another way of figuring out the number of pizzas we need would be to divide 30 by 10, and 30/10=3 would equal the number of pizzas. We need to figure out how many pizzas we need to have 30 slices, so we can divide here.

The logical statement that defines the relation (⊂) in terms of (∈) is:

A ⊂ B if every element of A is an element of B.

To prove that (A-B) ∩ (B-A) = ∅,

follow the steps below:

Step 1: To begin, assume that x ∈ (A-B) ∩ (B-A)

Step 2: This means that x is an element of both A-B and B-A.

Step 3: Since x ∈ A-B, x ∈ A, but x ∉ B.

Step 4: Since x ∈ B-A, x ∈ B, but x ∉ A.

Step 5: Since x ∈ A and x ∉ B, it is impossible for x to be in both A and B.

Step 6: Therefore, x cannot be in (A-B) ∩ (B-A).
