The solution is Option C.

The system of equations have no solutions as they are parallel lines

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of first line be A

Let the equation of second line be B

Let the first point be P ( 0 , 3 )

Let the second point be Q ( 3 , 4 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 4 - 3 ) / ( 3 - 0 )

Slope m = 1/3

Now , the equation of line A is

y - y₁ = m ( x - x₁ )

y - 3 = ( 1/3 ) ( x - 0 )

y - 3 = ( 1/3 )x

Adding 3 on both sides of the equation , we get

y = ( 1/3 )x + 3   be equation (1)

And , the third point is R ( 0 , -2 )

Let the fourth point be S ( 3 , -1 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( -1 - ( -2 ) ) / ( 3 - 0 )

Slope m = 1/3

Now , the equation of line A is

y - y₁ = m ( x - x₁ )

y - ( -2 ) = ( 1/3 ) ( x - 0 )

y + 2 = ( 1/3 )x

Subtracting 2 on both sides of the equation , we get

y = ( 1/3 )x - 2   be equation (1)

Hence , the equations have the same slope as m = 1/3 and they are parallel lines

The angle of rotation if an image is the result of a composition of two reflections across perpendicular lines is 180 degrees

Rotation and reflection are forms of transformation as seen in mathematics. The two are related in some forms.

There is a 0.3814 percent chance that a standard normal random variable will fall between 0.3 and 3.2.

In the posed query,

We must determine the likelihood that a standard normal random variable will occur with a probability between 0.3 and 3.2.

First, a standard normal random variable with a mean and standard deviation is introduced.

We must determine the likelihood that a standard normal random variable will fall within the range of 0.3 and 3.2.

The likelihood therefore should be

P(0.3<z<3.2)=P(z<3.2)−P(z<0.3)

Using z's typical value

P(0.3<z<3.2)=0.9993−0.6179

Simplifying

P(0.3<z<3.2)=0.3814

According to the z table, there is a 0.3814 percent chance that a standard normal random variable will fall between 0.3 and 3.2.

Answer:

C = 200 + 50p

Step-by-step explanation:

Here's a table of values:

Number of phones (p) 0 1 2

Cost of materials and labor ($50p) 0 50 100

Total cost ($200 + $50p) 200 250 300

From the table, we can see that the total cost, C, is equal to the fixed cost of $200 plus the cost of materials and labor, which is $50 per phone produced. So, the equation representing the total cost in dollars of producing p phones in a given day is:

C = 200 + 50p

The number of vehicles Luann had in mind is 135.

The calculation of the number of vehicles Luann had in mind is based on the ratio of the number of predicted SUVs to the number of predicted vehicles, and the actual number of SUVs seen by Luann.

First, we know that for every 45 vehicles that pass by, 14 are expected to be SUVs. This means that 14/45 of the vehicles are expected to be SUVs.

Next, we know that Luann saw 42 SUVs pass by. To find the actual number of vehicles that have passed by, we set up a proportion:

We can then solve for the actual number of vehicles by cross-multiplying and dividing:

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

here, we have,

Scientific notations have some of the profits as:

Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

We're given that:

The height of the statue of Abraham Lincoln memorial in Washington, DC  is 5.7912 m.

We can rewrite it as:

5.7912 ≈ 6

Since we need to write it as a single digit times an integer power of 10, therefore, we get:

6 × 10^{-3} (approx)

The size of a sample is related to the spread of the sampling distribution in that the larger the sample size, the less the spread.

As the sample size increases, the sampling distribution of p becomes increasingly concentrated around the true population proportion p. This is because, as the sample size increases, the number of possible random samples of size n becomes larger, making it more likely that the observed sample proportion will be close to the true population proportion.

The mean of the sampling distribution of p is p, which is the true population proportion. The standard deviation of the sampling distribution of p (σp) can be calculated using the formula:

σp = √((p)(1-p))/n

where p is the true population proportion and n is the sample size. This standard deviation indicates how closely the sample proportion is likely to match the true population proportion. The smaller the standard deviation, the more closely the observed sample proportion is likely to match the true population proportion.

Vertex of parabola = (-8 , -6)

Focus of parabola = (-8 , -23/4)

Directrix of parabola is y = -25/4

Axis of symmetry of parabola is x = -8

Direction of opening of parabola is vertically upwards.

y - intercept = 58 unit

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

Given equation of parabola

y = x² + 16x + 58

It can be written as

y = x² + 16x + 64 - 6

y = (x + 8)² - 6

Comparing with standard vertex form

y = a(x - h)² + k

Vertex (h, k) = (-8 , -6), a = 1

a = 1/4(f - k)

1 = 1/4(f - -6)

4f + 24 = 1

f = -23/4

Focus (h , f) = (-8 , -23/4)

Directrix is y = d

Distance from the focus to the vertex is the same as the distance from the vertex to the directrix.

-6 - (-23/4) = d - (-6)

d = -6 -6 + 23/4

d = -12 + 23/4

d = -25/4

Directrix is y = -25/4

The axis of symmetry is the line perpendicular to the directrix that passes through the vertex and the focus:

x = -8

Direction of opening will be vertically upwards

For y-intercept, x = 0

y = (0 + 8)² - 6

y = 64 - 6

y = 58

Hence, (-8 , -6) is Vertex of parabola

(-8 , -23/4) is Focus of parabola

y = -25/4 is Directrix of parabola

x = -8 is Axis of symmetry of parabola

Direction of opening of parabola is vertically upwards.

Since there are 30 exams in total, 30 x 0.75 = 22.5 exams have scores of 85 or lower. To find the number of exams with scores of 85 or greater, we subtract the number of exams with scores of 85 or lower from the total number of exams, which is 30 - 22.5 = 7.
