Answer:

y=4x-1

Explanation:

looking at the x row, as you can see, it goes up by 1 each time. In the y row, it goes up by 4, because -1+4=3, 3+4=7, etc. So your slope is 4, and in the funtion y=mx+b given, that would go in the “m” spot. Then for the “y” spot you need to figure out if x is 0, what is y. Well, that is given to you in the picture. It shows that when x=0, y=-1. So that is you y intercept, going into the b spot. If you put it together, it looks like this: “y=4x-1”.

As the single fraction, we can write the expression as -

k/x.

Given is the expression as follows -

a) Ninety percent is not a trustworthy estimate of the percent of all students who are outraged.

It is important to note that a sample of 5000 responses, while large, may not necessarily be representative of the entire population of students. The sample may have biases or limitations that affect the results of the survey. For example, the survey may have only been distributed to certain groups of students or there may have been a higher response rate from students who are particularly passionate about the issue.
In order to accurately estimate the percent of all students who are outraged, a representative sample of the entire population of students would need to be surveyed, and the survey would need to be designed and administered in a manner that minimizes biases and limitations.

The two numbers are 3 and 6. We can then solve for y using the quadratic formula:y = [9 ± √(81 - 120)]/2 , y = 3 or 6

The sum of two numbers (x + y) = 9

The product of two numbers (x * y) = 30

We can solve for x and y using the following equations:

x + y = 9

x * y = 30

We can solve for x by dividing both sides of the equation by y:

x = (30/y)

We can then substitute this into the first equation:

(30/y) + y = 9

We can then solve for y by subtracting 30/y from both sides:

y = 9 - (30/y)

We can then solve for y by multiplying both sides by y:

y^2 = 9y - 30

We can then solve for y using the quadratic formula:

y = [9 ± √(81 - 120)]/2

y = 3 or 6

Therefore, the two numbers are 3 and 6.

The slope is negative three halves for option 2 and the y-intercept is 2. Hence option 2 is the correct answer.

A line's steepness and direction are determined by the line's slope. Without actually using a compass, determining a line's slope in a coordinate plane can aid in determining whether the line is parallel, perpendicular, or not.

Any two clearly separated points on a line can be used to calculate the slope of any line. Calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined.

The y-intercept is obtained when the x coordinate is 0.

From the given options the y-intercept is 2 for option 1 and 2.

The slope is given as:

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

For option 1:

m = (0 - 2) / (3 - 0)

m = -2/3

For option 2:

m = (-1 - 2) / (2 - 0)

m = -3/2

So, the slope is negative three halves for option 2 and the y-intercept is 2. Hence option 2 is the correct answer.

The initial graph shows [tex]f(x)= 2(3)^{x}[/tex]

A function is a mathematical object that assigns a unique output (or "value") to each input in its domain. It is a rule that takes an input (or "argument"), performs some operations on it, and returns a corresponding output. Functions are often written using the notation f(x), where x is the input, and f(x) is the corresponding output. For example, the function f(x) = x^2 maps the input value x to its square. Functions are a key concept in mathematics and are used to model various phenomena in science, engineering, economics, and more.

The function provided is,

[tex]f(x)= 2(3)^{x}[/tex]

making x = 1

[tex]f(x)= 2(3)^{1}=f(x)= 2(3)=6[/tex]

The point (1, 6) that is (x, f(x)) must therefore satisfy the condition or be on the curve of the function.

The required system of equations equation besides y = 8x + 7 is y = 8x + 15  has no solution.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

A system of equations has no solution when the equations describe lines that are parallel and do not intersect. In other words, there is no common solution for both equations, or in other words, there is no ordered pair that satisfies both equations.

If y = 8x + 7 is one of the equations, the other equation could be any line that is parallel to it and does not intersect it. This means that the other equation would have the same slope as y = 8x + 7, which is 8, but a different y-intercept.

For example, y = 8x + 15 is a line that is parallel to y = 8x + 7 and does not intersect it. Thus, the system of equations

The length, width, and height of the right square prism are all equal to 7units, i.e., 7units * 7units * 7units.

The volume of a right square prism can be expressed as the product of its length, width, and height. If the volume is 360 cubic units, and the prism is a square prism, then we can assume that its length, width, and height are all equal, so we can call them x. The volume formula can be expressed as:

V = x * x * x = 360

Taking the cube root of both sides of the equation, we get:

x = ∛(360) = 7.11

The cube root of 360 is approximately 7, so the length, width, and height of the square prism are all equal to 7 units.

Among the 3 cards the probability of picking an odd number and then picking an odd number is 1/3.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The probability of picking a card with odd number is -

Probability = Favourable outcomes / Total outcomes

Substitute the values in the equation -

P(odd1) = Odd number of cards / Total number of cards

P(odd1) = [tex]\frac{^1C_1}{^3C_1}[/tex]

P(odd1) = 1/3

This is followed by picking up a second card without putting the first card back.

So, out of remaining two cards an odd card needs to be picked.

Probability = Favourable outcomes / Total outcomes

Substitute the values in the equation -

P(odd2) = Remaining odd number of cards / Remaining number of cards

P(odd2) = [tex]\frac{^0C_1}{^1C_1}[/tex]

P(odd2) = 0/1

P(odd2) = 0

The probability of both the events is -

P(odd1) + P(odd2)

1/3 + 0

a) The measure of an interior angle is of 135º.

b) The polygon has 8 sides.

An interior angle is supplementary with it's exterior angle, meaning that the sum of their measures is of 180º.

Hence the measure of the interior angle of a polygon with exterior angle of 45º is given as follows:

180 - 45 = 135º.

The sum of the interior angle measures of a polygon with n sides is given by the equation presented as follows:

S(n) = 180 x (n - 2).

For a regular polygon, all the angles have the same measure, hence:

S(n) = 135n.

Then the value of n, representing the number of sides of the polygon, is obtained as follows:

135n = 180(n - 2)

135n = 180n - 360

45n = 360

n = 360/45

n = 8 sides.

Answer: 3,2

Step-by-step explanation: The degree represents the highest exponent in the function. In this case, there is a cubed term which has an exponent of 3. The leading coeffient represents the number before x that makes that highest exponent and in this case its 2.

The expression to represents the phrase: "6 times a number plus 3." is:

6n + 3

Here, "n" represents an unknown number, and "6" and "3" are constants. The expression means that 6 is being multiplied by "n" to get an intermediate result, and then 3 is being added to that result to get the final answer.

For example, if n = 2, then the expression would evaluate to 6 * 2 + 3 = 12 + 3 = 15. So, the expression "6n + 3" represents the mathematical relationship between the unknown number "n" and the final result.

Answer:

e = 190

Step-by-step explanation:

Rearrange to:

e/(-95)+6-(4)=0

Now we simplify, and get this:

(e/-95 + 6) - 4 = 0

Rewrite the equation to get this:

6 = 6/1 = 6x(-95)/-95

after adding fraction with a common denominator we get:

(570 - e)/95 - 4 = 0

Rewrite the whole as an equivalent fraction:

4 = 4/1 = 4x95/95

After adding fractions with a common denominator we get:

190-e/95 = 0

Now we must get the numerator to equal 0:

190-e/95 x 95 = 0 x 95

We get:

190 - e = 0

So we solve:

-e + 190 = 0

Subtract 190 from both sides:

-e = -190

Multiply both sides by (-1):

e = 190

53.9 degree is the angle of the compass direction of a line connecting your starting point to your final position measured from north of west.

A compass is a tool for orientation and navigation that displays direction in relation to the four cardinal directions of the earth (or points). The directions north, south, east, and west are typically represented on the compass face as initialised abbreviations in a design called a compass rose. The rose can be aligned with the corresponding geographic directions when the compass is employed; for instance, the rose's "N" mark points northward. Compass roses are frequently joined with (or occasionally replaced by) marks indicating angles in degrees. East is 90° degrees, south is 180° degrees, and west is 270° degrees, with north being 0° and the angles increasing clockwise.

Step-by-step explanation:

We know

The ratio of students failing the test to students passing the test was 2/9

For every 11 students, 2 students fail the test, and 9 passes it.

2:9 = 11

143 students took the test. How many did not pass?

The first ship with an angle of depression 9° has a 2399.23m distance from the shore. And the first and second ship are on a 1944.19m distance apart.

The angle of depression is an angle formed between the horizontal line and the line of sight when an observer looks downwards.

Considering the right triangle formed by the height of the cliff and the distance of the ships from the shore, we shall derive a complementary angle considering their respective angles of depression as:

90° - 9° = 81° for the first ship

90° - 5° = 85° for the second ship

such that;

tan 81° = distance of the first ship from the shore/380m {opposite/adjacent}

distance of the first ship from the shore = 380m × cos 81°

distance of the first ship from the shore = 2399.23m

tan 85° = distance of the second ship from the shore/380m {opposite/adjacent}

distance of the second ship from the shore = 380m × cos 85°

distance of the second ship from the shore = 4343.42

the ships distance apart = 4343.42m - 2399.23m

the ships distance apart = 1944.19m

Therefore, first ship with an angle of depression 9° has a 2399.23m distance from the shore. And the first and second ship are on a 1944.19m distance apart.
