Find the equation of the linear function represented by the line that goes through: (0,-5) and (-2,-3) in slope-intercept form.

y = ___?___

As (-2, 2) and (4, -1) lie on a line the equation of the line is: y = (-1/2)x + 1

We can use the slope-intercept form of a linear equation,

which is y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope of the line using the two given points. The slope formula is:

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

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Plugging in the values, we get:

m = (-1 - 2) / (4 - (-2)) = -3/6 = -1/2

Now we have the slope (m = -1/2), and we can use either of the two given points to find the y-intercept (b).

Let's use the first point (-2, 2):

y = mx + b

2 = (-1/2)(-2) + b

2 = 1 + b

b = 1

So the equation of the line is:

y = (-1/2)x + 1

The roots of the polynomial equation are x = −1, 1/3, and 3.

A polynomial equation is a mathematical equation in which the polynomial is set to zero. The equation is made up of variables, non-negative integer exponents, coefficients, arithmetic operations, and an equal sign.

Finding the value(s) of 'x' that satisfy the polynomial equation p(x) = 0 is all that is required to solve the problem. A number "a" is a polynomial p(x) "zero" if and only when p(a) = 0. 

Given that:

3x³- 7x² - 7x + 3 = 0

Factor the left side of the equation.

(x + 1) (3x − 1)(x − 3) = 0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x + 1 = 0

3x − 1 = 0

x − 3 = 0

Set x + 1 equal to 0 and solve for x; x = - 1

Set 3 x − 1 equal to 0 and solve for x; x = 1/3

Set x − 3 equal to 0 and solve for x;  x = 3

The final solution is all the values that make (x + 1)(3 x − 1)( x − 3) = 0 true is x = −1, 1/3, 3.

a) The missing frequency is 20

b) The modal number of people in a car is 1

c) The median is 3

d) The mean is 0.95

The sum of the frequencies must be 60.

The missing frequency by subtracting the sum of the other frequencies from 60

60 - (28 + 3 + 7 + 1 + 1) = 20

To find the median, we need to arrange the data in order from smallest to largest:

1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5, 6

There are 60 numbers in total, so the median is the average of the 30th and 31st numbers:

median = (3 + 3)/2 = 3

The mode is the value with the highest frequency, which is 1.

mean = (1 x 28 + 2 x 20 + 3 x 3 + 4 x 7 + 5 x 1 + 6 x 1) / 60

= (28 + 40 + 9 + 28 + 5 + 6) / 60

The time taken by the new computer to send an email found using the unitary method, is 7.5 minutes.

What is a unitary method?

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Let,

Time taken by new computer to send 1 email = x

Time taken by the old computer to send same mail = 2x

Using unitary method

In 1 minute

Work done by new computer = 1/x

Work done by old computer =1/2x

Given the time taken when both computers work together  = 5 minutes

Work done in 1 minute by both = 1/5

So we can write,

1/x + 1/2x = 1/5

3/2x = 1/5

x = 7.5 minutes

Therefore the time taken by the new computer to send an email found using the unitary method, is 7.5 minutes.

Yes, the product of (x - 3)^2 is a perfect square trinomial because it can be written as the square of the binomial (x - 3).

A perfect square trinomial is a trinomial of the form a^2 + 2ab + b^2, where a and b are terms that can be squared. When we expand the square of a binomial, we get a perfect square trinomial.

In this case, the binomial is (x - 3), and its square is (x - 3)^2. When we expand this expression, we get:

(x - 3)^2 = (x - 3)(x - 3) = x^2 - 6x + 9

This is a perfect square trinomial, because it can be written as the square of the binomial (x - 3). Specifically, we can write:

(x - 3)^2 = (x - 3)(x - 3) = (x - 3)^2

Therefore, the product of (x - 3)^2 is a perfect square trinomial.

By understanding what composite numbers are and how they relate to rolling a die, we can determine the expected number of times Ms. Rod will roll a composite number in 57 rolls.

A composite number is a positive integer that has at least one positive divisor other than one or itself. In other words, a composite number is a number that can be factored into smaller positive integers.

To find the number of times Ms. Rod should expect to roll a composite number, we need to know how many numbers from 1 to 6 are composite. Only two numbers are prime in this range, namely 2 and 3. This means that the other four numbers (4, 5, and 6) are composite. Therefore, out of the 6 possible outcomes of rolling the die, 4 of them are composite numbers.

We can use this information to calculate the expected number of times Ms. Rod will roll a composite number. We know that she is rolling the die 57 times, and each roll has a probability of 4/6 (or 2/3) of resulting in a composite number. Therefore, we can use the formula for the expected value of a discrete random variable, which is:

Expected value = (number of trials) x (probability of success)

Plugging in the values, we get:

Expected value = 57 x 2/3

Expected value = 38

Therefore, we can expect Ms. Rod to roll a composite number about 38 times out of 57 rolls. However, it's important to note that this is just an expected value, and the actual number of times she rolls a composite number may vary.

Shawna's new score can be represented by the equation is New Score = Current Score + (Result of Black Cube) + (Result of Red Cube). So, Shawna's new score is 2.

In the game that Shawna is playing, rolling the black cube results in a positive number, while rolling the red cube results in a negative number. We are told that Shawna's current score is 4, which means that she has accumulated 4 points up to this point in the game.

Next, we are told that Shawna rolls a red 5 and a black 3. This means that the red cube resulted in a negative 5 and the black cube resulted in a positive 3.

To calculate Shawna's new score, we can add the results of these two rolls to her current score. However, we need to be careful to subtract the negative number, rather than adding it. This is because a negative number is actually a decrease in score.

Therefore, we can use the following equation to calculate Shawna's new score:

New Score = Current Score + (Result of Black Cube) + (Result of Red Cube)

Substituting in the values that we know, we get:

New Score = 4 + 3 + (-5)

Simplifying, we can combine the positive and negative numbers:

New Score = 4 - 2

Therefore, Shawna's new score is 2. This means that after rolling a red 5 and a black 3, her score has decreased by 2 points from her original score of 4.
