a line passes through tge points (1,-3) and (4,6) what is the zero of this line ?

Answers

Answer:

The zero of the line is (2,0)

Step-by-step explanation:

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:

[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

We are given the points (1,-3) and (4,6). Substituting:

[tex]\displaystyle y+3=\frac{6+3}{4-1}(x-1)[/tex]

Operating:

[tex]\displaystyle y+3=\frac{9}{3}(x-1)[/tex]

[tex]y+3=3(x-1)[/tex]

The zero of this line can be found by making y=0 and solving for x:

0+3=3(x-1)

3=3x-3

Adding 3:

6=3x

Solving:

x = 2

The zero of the line is (2,0)

You are to take a multiple-choice exam consisting of 100 questions with 2 possible responses to each question. Let x represent the number of correct responses on the test. A) What is your expected score on the exam?B) Compute the variance and standard deviation of x.

Answers

Answer:

50 ;

25 ;

5

Step-by-step explanation:

Given that:

Number of multiple choice questions = 100

Number of possible responses = 2

Hence, probability of success, p = 1/2 = 0.5

Using normal approximation :

The expected score = mean = n*p

Expected score (X) = 100 * 0.5 = 50

standard deviation = std(X) = √

Var(X) = n*p*q

q = 1 - p = 1 - 0.5 = 0.5

Variance = Var(X) = (100 * 0.5 * 0.5)

Var(X) = 25

Var(X) = 25

The Standard deviation (Std) = √Var(X)

Std(X) = √25

Std(X) = 5

Two polygons are said to be similar under the following conditions:

1. Corresponding angles of the hexagons are congruent.

2. Corresponding sides of the hexagons are proportional.

As hexagons are similar, the following statement must be true:

You have discovered another alien. Find the correct rescue path before answering this question. Which statements are true about the equation of the line used to save this alien? The y-intercept is not visible on the graph. The slope does not exist for this line. The y-intercept is positive. The line crosses the x-axis at –3.

Answers

The correct answers are option A and option D.

What is a slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

From the given graph it is clear that the spaceship is located at (-4,3). The alien is at (-2, -3).

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

y - 3 = (-3 -3 ) / (-2 + 4) x (x + 4)

y - 3 = -3x -12

y = -3x -9

The equation of the line is;

y = -3x -9    {equation 1}

Slope intercept form of a line is

y = mx + b          {equation 2}        ,

where m is the slope and b is the y-intercept.

On comparing the equation (1) and (2) we get

It means,

Slope = -3

y-intercept = -9

Points from -6 to 6 are labeled on y-axis. The y-intercept is -9, so it is not visible on the graph.

Option A is correct.

Substitute y=0 in equation (1) to find the x-intercept.

Divide both sides by 3.

x-intercept is -3. It means the line crosses the x-axis at -3.

Option D is correct

Therefore, the correct options are A and D.
