Answer:

D

Step-by-step explanation:

A translation along - 5 means subtracting 5 from the x- coordinate

A translation of - 3 means subtracting 3 from the y- coordinate , so

J (- 2, 9 ) → J' (- 2 - 5, 9 - 3 ) → J' (- 7, 6 ) → D

The coordinates of the image of J ( -2, 9 ) after the translation will be equal to J' (- 7, 6 ).

The process of changing the location of the image on the coordinate system will be known as the translation.

The given coordinate of the point is; J ( -2, 9 )

A translation along negative 5 means subtracting 5 from the x- coordinate

A translation of negative  3 means subtracting 3 from the y- coordinate, so

So the translation will be calculated as;

J (- 2, 9 )

J' (- 2 - 5, 9 - 3 )

J' (- 7, 6 )

Hence, the coordinates of the image of J ( -2, 9 ) after the translation will be equal to J' (- 7, 6 ).

Answer:

  y -k = m(x -h)

Step-by-step explanation:

To translate a function right by h units, replace x with (x -h).

To translate a function up by k units, replace y with (y -k).

The translated function is ...

  y -k = m(x -h)

Additional comment

You may recognize this as the "point-slope" form of the equation of a line. The "parent function" is the line through the origin with slope m:

  y = mx

The translation above makes it be a line through (h, k) with slope m.

Did this question in my notes lol

The statistics z is -1.878 and the p value is 0.0302

Given,

Number of random sample selected, n = 6967

Number of surveys returned, x = 1331

Estimated proportion of return rate;

p = 1331/6967 = 0.192

Significance level, ∝ = 0.01

z would represent the statistic

We investigate the assertion that the return rate is less than 20%, and the following hypotheses are tested:

Null hypothesis, p₀ ≥ 0.2

Alternative hypothesis, p₀ < 0.2

The statistics, z = (p - p₀) / √(p₀(1 - p₀)/n)

That is,

z = (0.191 - 0.2) / √(0.2(1 - 0.2)/6967) = -1.878

Using the alternative hypothesis and the following probability, we can now get the p value:

p value  = p(z < - 1.878) = 0.0302

We fail to reject the null hypothesis when the p value exceeds the significance level of 0.01 and there is insufficient evidence to support the conclusion that the return rate is less than 20% at 1% of significance.

Hello!

We can use the pythagorean theorem because one of the angles is 90 degrees. According to the theorem, a^2 + b^2 = c^2

a is 12, b is unknown, and c is 20

Now we use the theorem

12^2 + b^2 = 20^2

144 + b^2 = 400

b^2 = 256

b = sqrt(256)

Answer:

x = 40

Step-by-step explanation:

x - \(\frac{2}{3}\)y =  30  Replace y with 15

x - \(\frac{2}{3}\)(`15) = 30          \(\frac{2}{3}\)\((\frac{15}{1}\)) = \(\frac{30}{10}\) = 3

x - 10 = 30  Add 10 to both sides of the equation

x = 40

Check:

x - \(\frac{2}{3}\)y = 30

40 - \(\frac{2}{3}\)(15) =30

40 - 10 = 30

Answer:

x would be equal to 160.

Step-by-step explanation:

When y=15, \(\frac{2}{3}*15=10\).

So, we can rephrase this as \(\frac{1}{4}x-10=30\).

Because we need the end result to be equal to 30, we need to get \(40-10=30.\)

Because we need to make 40 with the fraction \(\frac{1}{4}\), we can have x be equal to 160, and we would get \(\frac{160}{4}=40\).

So, we know that x = 160.

The given differential equation, V" + 8y' + 6y = e3t, along with the initial conditions y(0) = 0 and y'(0) = 0, cannot be solved using Laplace transform.

Laplace transform is typically used to solve linear constant coefficient differential equations with initial conditions at t = 0. However, the presence of the term e3t in the equation makes it a non-constant coefficient equation, and the initial conditions are not given at t = 0. Hence, Laplace transform cannot be directly applied to solve this particular differential equation.

The given differential equation, V" + 8y' + 6y = e3t, is a second-order linear differential equation with variable coefficients. The Laplace transform method is commonly used to solve linear constant coefficient differential equations with initial conditions at t = 0.

However, in this case, the presence of the term e3t indicates that the coefficients of the equation are not constant but instead depend on time. Laplace transform is not directly applicable to solve such non-constant coefficient equations.

Additionally, the initial conditions y(0) = 0 and y'(0) = 0 are given at t = 0, whereas the Laplace transform assumes initial conditions at t = 0^-. Therefore, the given initial conditions do not align with the conditions required for Laplace transform.

Considering these factors, we conclude that the Laplace transform cannot be used to solve the given differential equation with the provided initial conditions. Thus, the correct choice is "None of these."

Kamal's marks in Mathematics and English are approximately 30.33 and 9.67, respectively.

To find the percentage of a value, simply multiply the hundredths corresponding to the percentage by the total amount. If you prefer, you can calculate the percentage as follows: 1st step: multiply the percentage by the value. 2nd step: divide the previous result by 100.

Given the information:

From equation 1, we can express M in terms of E:

\(M = 40 - E\)

Apply in the equation 2:

\((40 - E + 3) * (E - 4) = 360\\(43 - E) * (E - 4) = 360\\43E - 4E - 43 * 4 + 16E = 360\\55E - 172 = 360\\55E = 532\\E = 9.67\)

Now substitute the value and find the math value:

\(M + E = 40\\M + 9.67 ≈ 40\\M = 30.33\)

Therefore, Kamal's marks in Mathematics and English are approximately 30.33 and 9.67, respectively.

The conditional probability that the size of the family is less than 6 given that it is at least 3 is 1.

To find the conditional probability that the size of the family is less than 6 given that it is at least 3, we need to use the formula for conditional probability.

Let's denote A as the event that the size of the family is less than 6, and B as the event that the size of the family is at least 3.

The conditional probability of A given B, denoted as P(A|B), is calculated as follows:

P(A|B) = P(A and B) / P(B)

First, we need to find P(B), the probability that the size of the family is at least 3. Since the family is selected at random, we can assume that all possible family sizes have an equal chance of being selected.

Let's assume the total number of possible family sizes is n. The probability of selecting a family with at least 3 members is the sum of the probabilities of selecting a family with exactly 3 members, exactly 4 members, and exactly 5 members.

P(B) = P(3) + P(4) + P(5)

Next, we need to find P(A and B), the probability that the size of the family is both less than 6 and at least 3. Since any family size less than 6 is also at least 3, P(A and B) will be the same as P(B).

Finally, we can substitute the values into the formula for conditional probability:

P(A|B) = P(A and B) / P(B) = P(B) / P(B) = 1

Therefore, the conditional probability that the size of the family is less than 6 given that it is at least 3 is 1.
