Answer:

a) negative

b) -7/6

Step-by-step explanation:

The x value increased, but the y value decreased so the line goes down and has a negative slope

(y₁-y₂)/(x₁-x₂) is the slope where (x₁,y₁) and (x₂,y₂) are points on the line

The scale factor of the given parameters will be 1.75 and the length of qy is 2.37.

We have,

Point q as the center of dilation,

And,

Line wy is dilated to created line w'y',

And,

Length of yw' = 3.5,

And,

Length of qw = 2,

Also,

Length of qy' = 4.125,

Now,

First we will find out the length of qy,

i.e.

The lines are similar so in equal ratio,

i.e.,

qw : qy = qw' : qy'

Now,

Putting values,

i.e.

2 : qy = 3.5 : 4.15

on solving we get,

qy = 1.5

So,

The length of qy is 2.37.

Now,

Scale factor : Scale Factor is the ratio of size of new image formed to the size of old image.

i.e.,

Scale factor = \(\frac{Change\ in\ size}{Original\ size}\)

So,

Scale factor = \(\frac{3.5}{2}\) = 1.75

Hence, we can say that the scale factor of the given parameters will be 1.75 and the length of qy is 2.37.

You didnt specify what to do so i just assume this is a factorization question.

The probability that the next customer arrives in less than four minutes is 0.0821.11 and the probability that more than 190 of them are over 21 is 0.1814.

Given, Meantime, B = 10 minutes of the arrival of customers follows Exponential distribution with parameter λ, mean = B= 10 minutes. Exponential distribution is given as, f(x) = λ e^ (- λ x)For the probability that the next customer arrives in less than four minutes, we have to calculate the value of P(X < 4), X is the time between the arrivals of two customers. Put x = 4 in the above exponential distribution function, we get, P(X < 4) = λ e ^(- λ x) = λ e^(- λ 4) = P(X < 4)= λ e^-2.5 = P(X < 4) = 0.0821

Therefore, the probability that the next customer arrives in less than four minutes is 0.0821.11.

Given, p = 0.30, q = 0.70n = 600Number of students over 21 years of age, X ~ Binomial(n, p) = Binomial (600, 0.30) = B(600, 0.30)

Mean value of X, µ = np = 600 × 0.30 = 180, Standard deviation of X, σ = sqrt (npq) = sqrt (600 × 0.30 × 0.70) = 10.95

Let Z be the standard normal variable, Z = (X - µ) / σ = (190 - 180) / 10.95 = 0.91P(X > 190) = P(Z > 0.91) = 1 - P(Z < 0.91)

From the standard normal distribution table, the area to the left of 0.91 is 0.8186P(Z < 0.91) = 0.8186P(X > 190) = 1 - P(Z < 0.91) = 1 - 0.8186 = 0.1814

Therefore, the probability that more than 190 of them are over 21 is 0.1814.

Step-by-step explanation:

The linear function for this problem is defined as follows:

y = x + 50.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b

In which:

The graph touches the y-axis at y = 50, hence the intercept b is given as follows:

b = 50.

When x increases by 10, y also increases by 10, hence the slope m is given as follows:

m = 10/10

m = 1.

Hence the function is given as follows:

The possible scales factors of the given dilation transformation are 3/2 and -3/2. Hence, their sum is zero.

A dilation is a transformation that results in an image with the same shape as the original but a different size.

In a dilation transformation, a negative scale factor enlargement will cause the enlargement to appear on the opposite side of the enlargement's center and will be inverted (upside down). The size of the shape will also alter depending on the degree of the enlargement.

The areas are scaled by 9/4

Since, the area of a square is the square of its side, then scale factor is:

Scale factor = ±√(9/4) =  ± 3/2

Hence, the possible values are positive scale factor: 3/2 and negative scale factor = -3/2.

Their sum is: 3/2 + (-3/2) = 0

Incomplete problem...

Given:

The objective is to find the line of reflection at which the triangle carries onto itself.

Explanation:

To obtain the reflection of the rectangle on itself, it must reflect over the midpoint of each parallel side of the rectangle.

The line passing through the midpoint of the rectangle in the x-axis is x= 2.

Similarly, the line passing through the midpoint of the rectangle in the y-axis is y = 1/2.

Thus, the reflecting lines are x = 2 and y = 1/2.

Hence, option (A) is the correct answer.

Answer:

Yes, it should work.

Step-by-step explanation:

DC=AB  (because it is a rectangle and they are parallel)

The integral ˆ«(1 to [infinity]) xe^-x2 dx, is  E) divergent, that is, an indefinite integral with an upper limit of infinity.

Let's use the following steps to evaluate indefinite integral:

ˆ«(1 to [infinity]) xe^-x2 dx

We can start by making a substitution to simplify the integral.

We substitute u = -x^2, du = -2x dx. When x approaches infinity, u approaches negative infinity, and when x is 1, u is -1.

Now we can rewrite the integral with the substitution:

ˆ«(-1 to -infinity) e^(u/2) du

Next, we can use the limit property of integrals to evaluate the integral as u approaches negative infinity:

lim[u->-infinity] ˆ«(-1 to u) e^(u/2) du

As u approaches negative infinity, e^(u/2) approaches zero, so the integral becomes zero or the integral converges to zero.

There are 8 different trips that can be made from City X to City Z, passing through City Y.

To find the number of different trips that can be made from City X to City Z, passing through City Y, we can use the multiplication principle of counting.

First, we need to choose one of the 2 major roads from City X to City Y. Then, for each of these roads, there are 4 major roads from City Y to City Z, and we need to choose one of these roads.

By the multiplication principle of counting, the total number of different trips from City X to City Z, passing through City Y, is the product of the number of choices at each stage. Thus, we get:

Number of different trips = Number of roads from City X to City Y x Number of roads from City Y to City Z

= 2 x 4

= 8
