Isaac needs to add 165.84 grams of flour to the cake mixture.

To convert ounces to grams, we need to multiply the given weight in ounces by the conversion factor of 28.3495 grams per ounce. In this case, the weight of the flour is 5.85 ounces. So, we multiply 5.85 by 28.3495 to get the weight in grams:

5.85 oz * 28.3495 g/oz = 165.84 g

Therefore, Isaac needs to add 165.84 grams of flour to the cake mixture. This corresponds to option (d) in the given choices.

The definition of a regression equation is an equation used to assess whether a relationship exists between two sets of data.

What is the regression equation?

In statistics, a regression equation is used to determine whether or not there is a link between two sets of data. For instance, you might discover that a child grows roughly 3 inches a year if you measure their height each year. A regression equation can be used to model the three-inch growth tendency. In reality, most aspects of the real world—from gas prices to hurricanes—can be described using an equation of some form, which enables us to foretell the future.

The "best fit" line for your data is a regression line. In essence, you design a line that most accurately depicts the data points. It resembles the average of the points' locations. The regression line in a linear regression is a completely straight line:

An equation is used to express the regression line. The formula in this instance is 2.2923x + 4624. The line would be a rough approximation of your data if you plotted the equation -2.2923x + 4624.4.

It is unusual for all of the data points to actually lie on the regression line. The dots in the image above are a little dispersed around the line. The dots in the following picture are on the line. Polynomial regression, which fits the points to a polynomial equation, produced the curved curvature of this line.

The probability of winning on the fourth ticket is 0.83%.

Given, The probability of winning based on the type of lottery tickets we purchase is 0.05 or 1 in 20.

This means that the probability of winning is 1/20=0.05.We will play each Saturday until we win.

This statement gives us a hint that we need to find the probability of winning after four attempts/tries

Let the probability of not winning be (1-0.05)=0.95.

Now, the probability of not winning after 4 tries is:P(N) = 0.95 x 0.95 x 0.95 x 0.95 = 0.8145

The probability of winning on the fourth ticket is equal to the probability of not winning in three tickets (0.8145) multiplied by the probability of winning on the fourth ticket (0.05).

Thus, the probability of winning on the fourth ticket is:0.8145 x 0.05 = 0.040725 or 0.04

Summary: The probability of winning based on the type of lottery tickets we purchase is 0.05 or 1 in 20. We will play each Saturday until we win. The probability of winning on the fourth ticket is 0.83%.

Step-by-step explanation:

This problem is about linear equations. We assume Joe drive X miles, and the total cost is $Y, then we can get:

Plan I: Y=51.98+0.17X

Plan II: Y=59.98+0.13X

When both plans cost the same, 51.98+0.17X=59.98+0.13X. We will get X = 200

a. The number of students that this school is going to have to enroll abroad in the year 2001 is 150

b. In the 2018 academic year, it can be said that the school would also have to enroll 468 students in the school

a. The equation is as follows:

y = 123.1 * (1.069)^x

The value of x would be years that have changed.

To get the value of x we would have to find the differences that lies in the two years.

Hence

2001 - 1998 = 3

We would place the value of x in the equation

y = 123.1(1.069)³

Then

y = 150.4

This is approximately 150.

In conclusion, There would be 150 students enrolled in the school, according to estimates, in 2001.

b. For the year 2018

We would have to carry out similar calculation

x = 2018 - 1998

This would give us  20 years difference

Place x = 20 in the equation

y = 123.1(1.069)²⁰

y = 467.5

This is approximately

y ~ 468

468 would be enrolled in the school in 2018.

The value of sinx is 1 - 3cosx

What is Trigonometry?

Trigonometry is a field of mathematics that explores the connections between triangle side lengths and angles. The topic arose in the Hellenistic civilization during the third century BC from geometric applications to astronomical research. Today, four varieties of trigonometry are used: core, plane, spherical, and analytic. The ratio of the sides and angles of a right triangle is the subject of core trigonometry.

Solution:

1/cosx - tanx = 3

we can write tanx as sinx/cosx

this is because we know that sinx = Perpendicular / Hypotenuse

and cosx = Base / Hypotenuse

so if we divide sinx by cosx we will find that it is equal to Perpendicular / Base which is nothing but tanx

1-sinx = 3cosx

sinx = 1 - 3cosx

What are trigonometric functions?

Trigonometric functions are mathematical functions that relate the angles and sides of a right triangle. They are commonly used in geometry, physics, and engineering to solve problems involving triangles and periodic phenomena.

The basic trigonometric functions are:

Sine (sin): the ratio of the length of the side opposite an angle to the length of the hypotenuse of the triangle.

Cosine (cos): the ratio of the length of the side adjacent to an angle to the length of the hypotenuse of the triangle.

Tangent (tan): the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle.

Since angle R is a right angle, we know that angle ∠RSQ is complementary to angle ∠QRS. Therefore, we can find the measure of angle ∠RSQ by subtracting the measure of angle ∠QRS from 90 degrees:

∠RSQ = 90 - ∠QRS

To find the measure of ∠QRS, we can use the Pythagorean Theorem, since we know that triangle QRS is a right triangle:

\(QR^2 = QS^2 + RS^2\)

Substituting the given values, we have:

\(QR^2 = 98^2 + 84^2\)

\(QR^2 = 22580\)

QR = \(\sqrt{22580}\)

QR ≈ 150.3

Now we can use the trigonometric functions to find the measure of angle ∠QRS:

sin(∠QRS) = RS / QR

sin(∠QRS) = 84 / 150.3

sin(∠QRS) ≈ 0.559

∠QRS = \(sin^{-1}\)(0.559)

∠QRS ≈ 33.8 degrees

Therefore, the measure of angle ∠RSQ is:

∠RSQ = 90 - ∠QRS

∠RSQ = 90 - 33.8

∠RSQ ≈ 56.2 degrees

Rounding to the nearest tenth, we get:

∠RSQ ≈ 60 degrees

Just made my brain explode, but hope this helps! xD

Step-by-step explanation:

The equation for g(x) passing through the point (3, 8) and with a slope of 25 is y - 8 = 25(x-3)

The equation of a line in point slope form is expressed as:

y - y1 = m(x-x1)

where:

If the function g(x) is parallel to f(x), they will have the same slope. Hence the required slope is25.

Determine the required equation of a line

y - y1 = m(x-x1)

y - 8 = 25(x-3)

Hence the equation for g(x) passing through the point (3, 8) and with a slope of 25 is y - 8 = 25(x-3)

The best fit for explaining the growth of this particular function is option 3, polynomial.

A polynomial function is a function that can be expressed in the form of f(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₂x² + a₁x + a0, where n is a non-negative integer and a0, a1, a2, ..., an are constants.

In this case, the function is 2n³, which can be expressed as f(n) = 2n³ + 0n² + 0n + 0. This is a polynomial function of degree 3, which means it is a cubic function.  ( 3)

Constant functions have the form f(x) = c, where c is a constant. Exponential functions have the form f(x) = abx, where a and b are constants and b is positive.

Linear functions have the form f(x) = mx + b, where m and b are constants. None of these functions match the form of the given function, so the best fit for explaining its growth is a polynomial function.
