Function g is shown on the graph. If function f is the parent linear function, f(x) = x, what is the equation of transformed function g in terms of f?

Answers

Answer 1

Answer:

$\mathsf {g(x) = \frac{1}{2} f(x)}$

Step-by-step explanation:

$\textsf {Given :}$

$\implies\textsf {f(x) = x}\\\implies \textsf {Graph of g(x)}$

$\textsf {Now we see from the equation and the graph}\\ \textsf {that both of them passes through the origin,} \\\textsf {hence they have both the x and y intercepts as 0.}$

$\textsf {Take any 2 points on g(x), like (0,0) and (2, 1) and find the slope.}$

$\implies \mathsf {m = 1 - 0 / 2 - 0}$

$\implies \mathsf {m = 1/2}$

$\textsf {Hence, equation of g(x) :}$

$\implies \mathsf {g(x) = 1/2x}$

∴ $\mathsf {But, f(x) = x}$

$\textsf {Therefore, g(x) in terms of f(x) is :}$

$\implies \mathsf{g(x) = \frac{1}{2} f(x)}$

The truth value of the given proposition is "false".

The truth value of the given proposition can be evaluated using the following steps:

Convert the binary representation of the numbers to decimal:

0 = 0

~1 = -1 (invert the bits of 1 to get -2 in two's complement representation and add 1)

10 = 2

Apply the comparison operator "=" between the left and right sides of the equation:

(0 = -1) = 2

Evaluate the left side of the equation, which is false, because 0 is not equal to -1.

Evaluate the right side of the equation, which is true, because 2 is a nonzero value.

Apply the comparison operator "=" between the results of step 3 and step 4, which yields:

false = true

Therefore, the truth value of the given proposition is "false".

El triángulo ABC es equilátero y L, M y N son los puntos medios de BC, AB y CA respectivamente. Si MN = 3, ¿cuál es el valor de ML?

Answers

The value of ML = 3, using the mid-point theorem of triangles.

According to the midpoint theorem, "the line segment of a triangle crossing the midpoints of two sides of the triangle is said to be parallel to its third side and also half the length of the third side."

In the question, we are given that triangle ABC is an equilateral triangle, and L, M, and N are the midpoints of BC, AB, and CA respectively.

Thus, by the midpoint theorem, we can say that:

MN || BC, and MN = (1/2)BC,ML || AC, and ML = (1/2)AC, andNL || AB, and NL = (1/2)AB.

Assuming AB = BC = AC = x units, we get:

MN = (1/2)BC = x/2,ML = (1/2)AC = x/2, andNL = (1/2)AB = x/2.

Thus, the triangle LMN is an equilateral triangle.

Thus, MN = ML = NL.

Given MN = 3, we can write the value of ML = 3.

Thus, the value of ML = 3, using the mid-point theorem of triangles.

Suppose that a simple linear regression model is appropriate for describing the relationship between y = house price (in dollars) and x = house size (in square feet) for houses in a large city. The population regression line is y = 22,500 + 46x and σe = 5,000.
(a) What is the average change in price associated with one extra sq. ft of space?
$ ________
What is the average change in price associated with an additional 100 sq. ft of space?
$ ________
(b) Approximately what proportion of 2,000 sq ft homes would be priced over $120,000? ________ (You may need to use a table. Round your answer to four decimal places.)
Approximately what proportion of 2,000 sq ft homes would be priced under $110,000? _________ (You may need to use a table. Round your answer to four decimal places.)

Answers

(a) The average change in price associated with one extra sq. ft of space can be calculated by taking the coefficient of x in the population regression line, which is 46. Therefore, for each additional square foot of space, the average change in price would be $46.

To calculate the average change in price associated with an additional 100 sq. ft of space, we can simply multiply the coefficient by the number of square feet. Therefore, the average change in price associated with an additional 100 sq. ft of space would be $4,600.
(b) To determine the proportion of 2,000 sq ft homes priced over $120,000, we need to first calculate the predicted value of y for x=2,000 using the population regression line.
y = 22,500 + 46(2,000) = $95,500
Next, we need to standardize the predicted value of y by dividing it by the standard error of the estimate (σe).
z = (120,000 - 95,500) / 5,000 = 4.90
Using a standard normal distribution table, we can find that the proportion of homes priced over $120,000 is approximately 0.00003 or 0.003%.
To determine the proportion of 2,000 sq ft homes priced under $110,000, we can follow the same steps but with a different predicted value of y.
y = 22,500 + 46(2,000) = $95,500
z = (110,000 - 95,500) / 5,000 = 2.90
Using the standard normal distribution table again, we can find that the proportion of homes priced under $110,000 is approximately 0.0021 or 0.21%.

Answers

Answer:

1/2

Step-by-step explanation:

When you find the sine of an angle, it is the opposite side / hypotenuse. This means that the hypotenuse of this triangle is 2 and the side opposite to 60° is √3. This means that the side adjacent to 60° is 1 (Pythagorean Theorem). When you find the cosine of an angle, it is the adjacent side / hypotenuse, which in this case will be 1 / 2. Hope this helps!

Answer:

1/2.

Step-by-step explanation:

Sine = opposite side / hypotenuse.

The side opposite 60 degrees has length√3 and the hypotenuse = 2.

By Pythagoras the side adjacent to the angle 60 = √( 2^2 - 3)

= 1 unit.

So cos 60 = adjacent / hypotenuse = 1/2.

Answers

The proportion of the variation in the dependent variable y that is explained by the estimated regression equation is measured by the coefficient of determination.

What is coefficient of determination?

The effectiveness of a statistical model in forecasting a result is shown by the coefficient of determination (R²). The dependent variable in the model is a representation of the result.

R² can have a value of 0 or 1, with 1 being the maximum achievable. Simply said, a model's R² will be closer to 1 the more accurate its predictions are.

R² is a more precise measure of goodness of fit. The amount of volatility in the dependent variable that the model can account for.

You can typically tell whether your linear regression data's R² is high or low by graphing it. The graphs below, for instance, display two sets of simulated data:

Part D: What is the conditional probability of the dependent event "red then green?" Decimal: P(1st Red and 2 nd Green )= Percent: P(1 st Red and 2 nd Green )=

Answers

Part A:What is the probability of getting a red jellybean on the first draw?

Given information: Red jellybeans = 12 Yellow jellybeans = 8 Green jellybeans = 4 Total jellybeans = 24 The probability of getting a red jellybean on the first draw is:

Probability of getting a red jellybean=Number of red jellybeans/Total jellybeans=12/24=1/2=0.5

Decimal: P(1st Red)=0.5 Percent: P(1 st Red )=50%

Part B: Let's say you did get a red jellybean on the first draw.

What is the probability that you will then get a green on the second draw?

Now, the total number of jellybeans is 23, since one red jellybean has been taken out. The probability of getting a green jellybean is: Probability of getting a green jellybean=Number of green jellybeans/Total number of jellybeans=4/23=0.174 Decimal: P(2nd Green | 1st Red )=0.174 Percent: P(2nd Green | 1st Red )=17%

Part C: If you had gotten a yellow on the first draw, would your answer to Part B be different?

Yes, because there is only 1 rotten egg yellow jellybean and if it were chosen in the first draw, it would not be returned back to the container. Therefore, the total number of jellybeans would be 23 for the second draw, and the probability of getting a green jellybean would be:

Probability of getting a green jellybean=Number of green jellybeans/Total number of jellybeans=4/23=0.174

Thus, the answer would be the same as Part B.

Part D: What is the conditional probability of the dependent event "red then green?"

Given that one red jellybean and one green jellybean are selected: Probability of the first jellybean being red is 1/2

Probability of the second jellybean being green given that the first jellybean is red is 4/23

Probability of "red then green" is calculated as follows: Probability of red then green=P(Red) × P(Green|Red)= 1/2 × 4/23 = 2/23 Decimal: P(1st Red and 2nd Green )=2/23 Percent: P(1st Red and 2nd Green )=8.70%

Answers

A probability distribution is an assignment of probabilities to each distinct value of a discrete random variable or to each interval of values of a continuous random variable.

A probability distribution is a mathematical function that assigns probabilities to all possible outcomes of a random variable. It describes the likelihood of each possible value or range of values occurring.

For a discrete random variable, which takes on distinct values, the probability distribution assigns probabilities to each possible value. It specifies the probability of observing each value of the random variable.

For a continuous random variable, which takes on a range of values, the probability distribution assigns probabilities to intervals or ranges of values. Since there are infinitely many possible values within a range, the probability of observing a specific value is usually zero. Instead, the probability distribution provides probabilities for intervals of values, indicating the likelihood of the random variable falling within those intervals.

XY = 11

Step-by-step explanation:

XY = YZ

3x +2 = x +8

2x = 6 . . . . . . . . . subtract x+2

x = 3

XY = 3 +8 . . . . . . . . x +8 is the same as 3x+2

XY = 11

Answer:

$\boxed {\boxed {\sf XY= 11}}$

Step-by-step explanation:

We are asked to find the value of XY.

We know that Y is the midpoint of XZ. The midpoint of a line bisects the line or divides it into 2 equal parts. The point Y divides the line XZ into 2 parts : XY and YZ. Since Y is the midpoint, XY and YZ are equal.

$XY= YZ$

We know that XY is equal to 3x+2 and YZ is equal to x+8.

$3x+2=x+8$

Now we can solve for x by isolating the variable. Move all the terms with variables to one side and the constants to the other side. Subtract x from both sides of the equation.

$(3x-x) +2 = (x-x)+8$

$2x+2=8$

Subtract 2 from both sides of the equation.

$2x+(2-2)= (8-2)$

$2x=6$

Divide both sides of the equation by 2.

$2x/2= 6/2$

$x= 6/2 \\x=3$

Now we know that x is equal to 3 and we can substitute it back into 3x+2 to solve for XY.

$XY= 3x+2 \\XY=3(3) +2\\XY=9+2 \\XY=11$
