Answer:

The inverse function can be written as:

g(x) = (x - 7 + √3) / 5

Step-by-step explanation:

Starting with the equation y = 5x + 7 - √3, we switch the roles of x and y to get x = 5y + 7 - √3.

Next, we isolate y by subtracting 7 and adding √3 to both sides, which gives x - 7 + √3 = 5y.

Finally, we divide both sides by 5 to get g(x) = (x - 7 + √3) / 5.

This is the inverse function g(x) of f(x) = 5x + 7 - √3. The inverse function is useful in solving problems where the original function is not explicitly invertible.

The probability you expect the spinner to not land on B is 0.4.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, a spinner is divided into three equal parts A, B, and C.

The repeated experiment of spinning the spinner twice is simulated 125 times.

The total number of outcomes = 125

The number of favorable outcomes = 12+18+15+17+13= 75

Probability of landing on B = 75/125

= 0.6

Probability of not landing on B

= 1-0.6

= 0.4

Therefore, the probability you expect the spinner to not land on B is 0.4.

In a right triangle, the Pythagorean theorem states that the sum of the legs squared is equal to the hypotenuse squared.

Or that a² + b² = c²

Where and and b are the legs and c is the hypotenuse

(Note that the hypotenuse is the longest side and the legs are the two shorter sides)

Here, we are given the length of the hypotenuse as well as the length of one of the legs. Given this we are asked to find the other leg UT.

We can find the length of UT by plugging in the given values into the Pythagorean Theorem and then solving for the missing variable.

Because the given hypotenuse is 17 we can say that c = 17 and since a leg is given we can say that a = 8

Plugging this into the formula we acquire (b is UT or the other leg)

8² + b² = 17²

==> evaluate the exponents

64 + b² = 289

==> subtract 65 from both sides

b² = 225

==> take the square root of both sides

b = 15

option B is correct, the equation or function of the graph is y≥3/4x-3.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

The cumulative frequency and relative cumulative frequency for students who earned a score of 20 or lower on the quiz is 29; 58%. (option d)

Cumulative frequency refers to the running total of frequencies, or the sum of frequencies up to a certain point. In this case, the cumulative frequency is the number of students who scored 20 or lower on the quiz.

Relative cumulative frequency, on the other hand, expresses the cumulative frequency as a percentage of the total number of students in the sample. To find the relative cumulative frequency, we divide the cumulative frequency by the total number of students and multiply by 100.

Therefore, for students who scored 20 or lower on the quiz, the cumulative frequency is 29 and the relative cumulative frequency is 58% (29/50 * 100).

Recall that for cumulative frequency we add up all the values that fall above or below a given bin of data. So, if we want all scores less than 20 it should be the first four bins with a total of:

8 plus 8 plus 13 plus 9 equals 38

To get the relative frequency we take the total in the bins for scores of 20 and lower divided by the total of all bins:

38 over 50 equals 0.76 equals 76 percent sign

The quadratic equation that we need to solve is:

96 = 208 - 16t^2

And the solution is t = √7

We know that the height equation is the quadratic equation below:

h = h0 - 16t^2

If the initial height is 208, then we can write:

h = 208 - 16t^2

Now we can find how long takes to reach a height of 96 feet, then we can write:

96 = 208 - 16t^2

That is the equation we need to solve.

Solving that for t we will get:

96= 208 - 16t^2

16t^2 = 208 - 96

16t^2 = 112

t^2 =112/167

The population of bacteria after h hours is 0.075.

Bacterial growth is proliferation of bacterium into two daughter cells, in a process called binary fission. Providing no event occurs, the resulting daughter cells are genetically identical to the original cell. Hence, bacterial growth occurs. Both daughter cells from the division do not necessarily survive. However, if the surviving number exceeds unity on average, the bacterial population undergoes exponential growth.

The equation that models the population of bacteria h-hours after the original 275 bacteria were measured is given by:

P(h) = 275 × [tex](1 + 0.075)^h[/tex]

p(h)=0.075

where P(h) is the population of bacteria after h hours and 0.075 is the growth rate of 7.5% per hour.

We subtract 8 from the x-coordinate and add 20 to the y-coordinate of the original point.

In mathematics, translation refers to the process of moving an object from one location to another, without rotating or scaling it. The movement is described by a vector, which is a directed line segment that specifies the direction and distance of the movement.

In two-dimensional geometry, a translation can be represented by a shift of an object along the x- and y-axes. For example, if a point is translated by a vector (a, b), its new position will be (x + a, y + b), where (x, y) is the original position of the point.

Translations can also be performed on shapes, such as lines, polygons, or curves. The effect of a translation on a shape is to create a new shape that is identical to the original shape, but located in a different position.

A translation is a transformation that moves a figure in a certain direction and by a certain distance without rotating or reflecting it. To find the rule for a translation, we need to find the vector that represents the displacement between the original point and the translated point.

Given two points A (2, -5) and A' (-6, 15), the translation vector is given by:

Translation vector = A' - A = (-6, 15) - (2, -5) = (-6 - 2, 15 - (-5)) = (-8, 20)

So, the rule for the translation is:

(x, y) -> (x - 8, y + 20)

This means that to apply the translation, we subtract 8 from the x-coordinate and add 20 to the y-coordinate of the original point.

Answer:

4 middle carriages have 162 passengers

Step-by-step explanation:

Since every 10 consecutive carriages have 398 passengers, then each carriage has 398/10 = 39.8 passengers.

Since there are 36 carriages in the train, then there are 36 * 39.8 = 1428 passengers in the train.

Therefore, there are 1400 - 1428 = -28 passengers missing.

This means that each carriage has 39.8 - (-28/36) = 39.8 + 0.78 = 40.58 passengers.

So, the 4 middle carriages have 4 * 40.58 = 162.32 passengers.

Rounding to the nearest whole number, we can say that 4 middle carriages have 162 passengers.

Answer:

  192

Step-by-step explanation:

If a train with 36 carriages holds 1400 passengers, 398 in any 10 consecutive carriages, you want to know the number in the 4 middle carriages.

The first 30 carriages will hold 3·398 = 1194 passengers, so there must be 1400 -1194 = 206 in the remaining 6 carriages. The same would be true counting carriages from the other end.

Then the 10 +6 carriages at either end of the train must hold 398 +206 = 604 passengers. That leaves 1400 -2·604 = 192 passengers in the middle 4 carriages.
