A regression model allows us to examine how the probability distribution of a dependent variable, Y, might be related to one or more independent variables (collectively called X). Therefore, the correct answer is (a) regression model.

A regression model is a statistical tool used to model the relationship between a dependent variable (often denoted as Y) and one or more independent variables (often denoted as X). It can help us understand how changes in the independent variables affect the values of the dependent variable, and can be used to make predictions or estimate values of the dependent variable based on specific values of the independent variables.

Answer:

Bisecting an Angle.

Step-by-step explanation:

This image shows the Bisection of an Angle. The 'x' shaped mark between the angle is formed when a protractor is used to mark the place in which a ray must pass through the center of the 'x' to be an equal bisection of the angle. This shows that the process that is being undergone is finding the bisection of the angle.

Answer:

bisecting an angle

just took the test!

Step-by-step explanation:

The relationship between an inscribed angle and a central angle that intercept the same arc is known as inscribed angle theorem.

An inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle.

It can also be defined as the angle subtended at a point on the circle by two given points on the circle.

This theorem states that angle subtended in the center of a circle is twice the angle subtended at the circumference of the circle.

So the relationship between an inscribed angle and a central angle that intercept the same arc, is that the inscribed angle is half of the central angle.

For given right triangles the value of a = 6√2 and b = 5/√3

In this question we have been given two right triangles.

In the first right triangle, we need to find the value of b.

Consider the tangent of angle 30°

tan(30°) = b/5

1/√3 = b/5

b = 5 × (1/√3)

b = 5/√3

In the second right triangle, we need to find the value of a.

This right triangle is isosceles right triangle.

So, the sides of right triangle are: a, 6, and 6

Using Pythagoras theorem,

a = √(6² + 6²)

a = √[2×(6²)]

a = 6√2

Therefore, for given right triangles the value of a = 6√2 and b = 5/√3

The correct values are;

1) (f + g)(2) = 10

2) (f − g)(4) = - 4

3) (f ÷ g)(2) (f × g)(1) = 0

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

The functions are,

f (x) = 2x + 3

g (x) = x² - 1

Now,

Solve the given expressions as;

1) (f + g)(2) = f (2) + g (2)

               = (2 × 2 + 3) + (2² - 1)

               = 7 + 4 - 1

               = 10

Thus, (f + g)(2) = 10

2) (f − g)(4) = f (4) - g (4)

                = (2 × 4 + 3) - (4² - 1)

                = 11 - 16 + 1

                = - 4

Thus, (f − g)(4) = - 4

3) (f ÷ g)(2) (f × g)(1) = f (2)/g(2)  (f (1) × g(1))

                            = (2 × 2 + 3) / (2² - 1)  {(2 + 3) × (1 - 1)}

                            = 7/3 × 0

                            = 0

Thus, (f ÷ g)(2) (f × g)(1) = 0

Therefore, The correct values are;

1) (f + g)(2) = 10

2) (f − g)(4) = - 4

3) (f ÷ g)(2) (f × g)(1) = 0

Step-by-step explanation:

It will take at least 14 weeks to have at least $500.

The relation between two unequal expressions is defined as inequality.

Given that, the person has $150 in his account and he deposits $25 each week into this account.

The amount in the account after w weeks is:
150 + 25w

Let the amount in the account after w weeks is at least $500, then  it follows:

150 + 25w ≥ 500

25w ≥ 500 - 150

25w ≥ 350

w ≥ 14

Hence, it will take at least 14 weeks to have at least $500.

Answer:

1 = 8 and 50

2= 50 and a

Step-by-step explanation:

The value of x that makes lines e and f parallel and intersected by transversal b is x = 25. Answer choice (c) is correct.

Lines that are parallel to one another on a plane do not intersect or meet at any point. They are always equidistant from one another and parallel. Non-intersecting lines are parallel lines. Parallel lines can also be said to meet at infinity.

When parallel lines e and f are cut by a transversal, the corresponding angles are congruent. Using this fact, we can set up an equation involving the angles formed by the intersection of lines e and f with transversal b:

2x + 10 = 3x - 15

Solving for x, we get:

x = 25

Therefore, the value of x that makes lines e and f parallel and intersected by transversal b is x = 25. Answer choice (c) is correct.

An inequality to represent the relationship between the amount they made and the number of large glasses they sold is C > P * L + 65

Let's denote:

L as the number of large glasses of lemonade sold,

S as the number of small glasses of lemonade sold,

C as the total amount made from selling lemonade ($250), and

P as the price of a large glass of lemonade ($4.00).

The total sales generated from selling small glasses of lemonade is given as $65.

We can set up an inequality to represent the relationship between the amount made and the number of large glasses sold as follows:

C > P * L + 65

In this case, the total amount made (C) should be greater than the product of the price of a large glass of lemonade (P) and the number of large glasses sold (L), added to the total sales generated from selling small glasses of lemonade ($65).

This inequality ensures that the amount made exceeds the revenue from selling the large glasses and the additional $65 from the small glasses.

The polynomial function of the lowest degree that has -5, -2, and 0 as roots is f(x) = (x - 2)(x - 5).

To find the polynomial function of the lowest degree with -5, -2, and 0 as roots, we can use the factored form of a polynomial. If a number is a root of a polynomial, it means that when we substitute that number into the polynomial, the result is equal to zero.

In this case, we have the roots -5, -2, and 0. To construct the polynomial, we can write it in factored form as follows: f(x) = (x - r1)(x - r2)(x - r3), where r1, r2, and r3 are the roots.

Substituting the given roots, we have: f(x) = (x - (-5))(x - (-2))(x - 0) = (x + 5)(x + 2)(x - 0) = (x + 5)(x + 2)(x).

Simplifying further, we get: f(x) = (x^2 + 7x + 10)(x) = x^3 + 7x^2 + 10x.

Therefore, the polynomial function of the lowest degree with -5, -2, and 0 as roots is f(x) = x^3 + 7x^2 + 10x.

The question asks for the polynomial function of the lowest degree that has –5, –2, and 0 as roots. To find the polynomial, each root needs to be written in the form of (x - root). Therefore, the roots would be written as (x+5), (x+2), and x. When these are multiplied together, they form a polynomial function of the lowest degree.

Thus, the polynomial function of the lowest degree that has –5, –2, and 0 as roots is f(x) = x(x + 2)(x + 5).

Answer:

Step-by-step explanation:

We have

\(e^\frac{x}{2}^l^n^3 = 5\\\)

\(ln(e^\frac{x}{2}^l^n^3) = ln(5)\\\frac{x}{2}ln(3) = ln(5)\\\frac{x}{2} = \frac{ln(5)}{ln(3)} \\x = \frac{2ln(5)}{ln(3)}\)

\(x = 2.929947041\)

to the third decimal is 2.930 (i might be wrong on the rounding part)

In this case, the marked price of 220 is the cost price and discount of 20% is announced on sales, so the selling price is 176.

The t-shirt costs $166.5 to purchase. To do this, multiply the listed price (220) by the discount rate (20%) stated as a decimal. This will give you the amount of the discount (0.20).

220*0.20 =44

The selling price is then determined by deducting the discount (44) from the marked price (220):

220-44 =176

Before applying any markups or reductions, the retailer paid the item's cost price, commonly referred to as the wholesale price. The price a consumer pays to purchase an item is known as the selling price. The selling price will be less than the advertised price if a discount is being offered, and the difference between the two represents the discount.
