Answer:

It is not possible to determine whether the lines are parallel based on the information given. To determine whether two lines are parallel, we need to calculate the slope of each line and compare them. The slope is calculated as the change in the y-coordinate divided by the change in the x-coordinate, or (y2-y1)/(x2-x1). Since we only have the coordinates of the endpoints of the lines and not the equations of the lines, we cannot calculate the slope and therefore cannot determine whether the lines are parallel.

Answer: lines are parallel

Step-by-step explanation:

Lines are parallel if they have the same slope

                      [tex]\boxed {The\ slope\ m=\frac{y_2-y_1}{x_2-x_1} }[/tex]

1) (2,6)  (4,10)

x₁=2    x₂=4    y₁=6    y₂=10

Hence,

[tex]\displaystyle\\m=\frac{10-6}{4-2} \\\\m=\frac{4}{2}\\\\m=2[/tex]

2) (-2,3)  (3,13)

x₁=-2   x₂=3   y₁=3   y₂=13

Hence,

[tex]\displaystyle\\m_1=\frac{13-3}{3-(-2)} \\\\m_1=\frac{10}{3+2} \\\\m_1=\frac{10}{5}\\\\m_1=2[/tex]

m=m₁=2

Hence, lines are parallel

The range is all real integers bigger than or equal to the range's y-coordinate if a quadratic function opens up. All real integers less than or equal to the range's y-coordinate are in the range if a quadratic function opens downward.

In the given question we have to explain, how we can find the range of a quadratic graph.

Because it is the most fundamental quadratic function, all quadratic functions collectively can be referred to as a family, with this particular function serving as the parent (i.e., not transformed in any way). This function can be used to start broadly generalising the domains and ranges of quadratic functions.

The range is partly determined by the pivotal point, or vertex. The parabola's opening direction is the other. The range is all real integers bigger than or equal to the range's y-coordinate if a quadratic function opens up. All real integers less than or equal to the range's y-coordinate are in the range if a quadratic function opens downward.

If the speed of the vehicle is greater than or equal to 60 miles per hour, the angle will be greater than or equal to zero and the trooper should issue a ticket.

Distance is defined as the product of speed and time.

If the speed limit is 50 miles per hour and a speeding ticket is issued for speeds of 10 miles per hour or more over the limit, then the trooper should issue a ticket for any speed greater than 50 + 10 = 60 miles per hour.

In general, the speed of a vehicle is given by the formula v = d/t, where v is the speed, d is the distance traveled, and t is the time it takes to travel that distance.

The angle at which a speeding ticket should be issued is determined by the ratio of the speed of the vehicle to the speed limit. If the speed of the vehicle is greater than the speed limit, then the ratio of the speed of the vehicle to the speed limit will be greater than 1.

Therefore, the trooper should issue a ticket for any angle that is equal to or less than 1.

Alternatively, you could also say that the trooper should issue a ticket when the angle is greater than or equal to zero. Since any number divided by 1 is equal to the original number, this means that the angle will be equal to the speed of the vehicle in miles per hour.

Therefore, if the speed of the vehicle is greater than or equal to 60 miles per hour, the angle will be greater than or equal to zero and the trooper should issue a ticket.

After solving for the internal angles of the given figure, we know that the value of ∠C is 44°.

An angle is formed when two straight lines or rays meet at a single terminal.

The place where two points converge is known as an angle's vertex.

The name "angel" comes from the Latin word "angulus," which means "corner."

Acute, obtuse, right, straight, reflex and full rotation are examples of basic angles.

By joining two rays at their termini, a geometric shape known as an angle is produced.

An angle is often stated in degrees.

So, let the angle is x.

2x + 3 + 3x + 9 + 2x - 4 + x = 360

Now, calculate for x as follows:

8x + 12 - 4 = 360

8x + 8 = 360

8x = 360 - 8

8x = 352

x = 352/8

x = 44°

Step-by-step explanation:

trial and error aint that hard

According to ERG theory, frustration over not being able to satisfy a higher-order need may cause regression to a lower level.

ERG theory is a psychological theory put forth by Clayton Alderfer.

ERG concept, An individual will put more effort into the higher category once needs in the lower category are met. An individual will put more effort into the lower category if needs in the higher category are not met.

Maslow's hierarchy of needs was further developed by Alderfer by being categorised into his ERG theory (Existence, Relatedness and Growth). The necessity of meeting the essential material needs of people falls under the existence category. Concerned in the relatedness category is the desire to uphold significant interpersonal connections.

The desire for personal growth is addressed in the growth category. These include the self-actualization traits and the intrinsic component from Maslow's esteem category.

in a simple manner we define the three stages of ERG theory

1. Existence -  what we need from a physiological point of view .

examples- a house , healthcare, etc.

2- Relatedness -  our social needs.

examples -  friendship, social connectivity, national identity, etc.

3-growth -  Self-realization needs.

examples- feelings , success, failure ,etc.

Hence, ERG Theory suggests that failure to meet higher-order need may trigger regression to an already fulfilled lower-order need.

All the properties of whole numbers are closed under addition and multiplication.

Whole numbers are a set of natural numbers including zero, but the set does not include fractions, decimals, and negative integers. The set of whole numbers is represented by ‘W’={0, 1, 2, 3, 4, 5, …...}

To check if the whole numbers are closed under subtraction or not we will check out the four properties namely, the closure property, the commutative property, the associative property, and the distributive property.

Let us consider each property one by one -

1. The closure property-

let's take two whole numbers say 5 and 3.

now, 5+3=8

and 5 × 3 =15

Thus, whole numbers are closed under addition and multiplication by closure property.

2. The commutative property-

let's take two whole numbers say 5 and 3.

now, 5+3=8 and 3+5=8,

hence, we get 3+5 = 5+3.

Also, 5 × 3 =15 and 3 × 5 =15

hence, we get 5 × 3 = 3 × 5

Thus, whole numbers are closed under addition and multiplication by commutative property.

3. The associative property-

let's take three whole numbers say 5, 3, and 1.

now (5+3)+1 = 9 and 5+(3+1)= 9

hence, we get (5+3)+1 = 5+(3+1).

Also, (5×3)×1 = 15 and 5×(3×1)= 15

hence, we get (5×3)×1 = 5×(3×1).

Thus, whole numbers are closed under addition and multiplication by associative property.

4. The distributive property-

let's take three whole numbers say 1, 6, and 5.

now, 1 × ( 6 + 5 ) =  1 + 6 – 1 × 5  = 1

        and 1 × ( 6 – 5 ) = 1 × 1 = 1

Hence, 1=1.

Also,  1 × (6×5)= (1 × 6) × (1 ×5) = 6 × 5 =30

and  1 × (6×5) = 1 × 30 =30

hence, we get 30=30.

Thus, whole numbers are closed under addition and multiplication by distributive property.

Hence, we can conclude that all the properties of whole numbers are closed under addition and multiplication.

Answer:

The equation y = 34x - 2 is the slope-intercept form of the equation y = 34x + b, where b is the y-intercept, which is the point where the line crosses the y-axis. The value of b in this case is -2, so the equation can be written as y = 34x - 2. This form of the equation makes it easy to find the slope (which is 34 in this case) and the y-intercept (which is -2 in this case) of the line.

If X is a radom variable for amount you win, Then the excepted value of game or expected income i.e E(X) is 8/13.

Expected Income is the result of multiplying your income by the probability of earning it. This expected revenue can be subtracted by the expected cost to get the expected profit.

Mathematically, E(X) = X₁p₁ + X₂p₂ + ---+ Xₙpₙ

where Xᵢ are observation and pᵢ probability of Xᵢ.

We have given that,

Total number of cards in standard card deck = 52

i.e total possible outcomes = 52

One card is drawn from deck.

Total number of king cards in 52-card deck = 4

Favourable outcomes that drawn card is king = 4

Probability of getting a king card , p = 4/52 = 1/13

Probability of not getting a king ,q = 1 - p

Answer:

(-infinity, -2) ∪ (-3, infinity).

Step-by-step explanation:

To solve this compound inequality, we need to first solve each inequality separately. For the first inequality, 4(z+1) > -4, we can distribute the 4 to get 4z + 4 > -4. Then, we can subtract 4 from both sides to get 4z > -8. Finally, we can divide both sides by 4 to get z > -2.

For the second inequality, 2z - 4 < -10, we can add 4 to both sides to get 2z < -6. Then, we can divide both sides by 2 to get z < -3.

Now that we have solved both inequalities, we need to consider their intersection. Since the inequalities are joined by the "or" operator, the solution is the union of the solutions to each inequality. In interval notation, this is represented as the union of the intervals (-infinity, -2) and (-3, infinity).

Therefore, the solution to the compound inequality in interval notation is (-infinity, -2) ∪ (-3, infinity).
