Consider the function f (x) = −2/3x + 5
What is f (25)?

A) 3
B) 10/3
C) 1/3
D) 3/10

Answer:

LCM = 840

Explanation:

First, we need to find the prime factorization of every number. So 14, 21, and 40 are equal to the product of the following prime number:

14 = 2 x 7

21 = 3 x 7

40 = 2 x 2 x 2 x 5

Now, we need to identify all the prime numbers and the maximum number of times that every prime appears. So, the prime numbers are:

2 = Appears maximum 3 times

3 = Appears 1 time

5 = Appears 1 time

7 = Appears maximum 1 time

So, the LCM is the multiplication of the prime numbers as:

LCM = 2 x 2 x 2 x 3 x 5 x 7

LCM = 840

Therefore, the LCM is 840

The null hypothesis to test for instruments' relevance is option D) H0:π2=0 or π3=0 or π4=0.In order to test the relevance of the instrument, the first stage equation's null hypothesis should be stated as: H0: π2 = 0 or π3 = 0 or π4 = 0.The relevance requirement will be fulfilled if we can refute the null hypothesis.

The null hypothesis will not be rejected if the F-statistic is less than 10.0. However, if the F-statistic is greater than 10.0, the null hypothesis will be rejected, indicating that the variables are relevant and that the instrument satisfies the relevance requirement.In summary, to test for instruments' relevance in TSLS, the null hypothesis of the first stage equation is stated as H0: π2 = 0 or π3 = 0 or π4 = 0.

Step-by-step explanation:

There are 2,352 possible combinations of two ice cream flavors and between zero and three toppings at the ice cream shop.

At the ice cream shop, you have the option to choose two scoops of ice cream from a selection of eight flavors. It is important to note that the order in which you choose the flavors matters. After selecting the ice cream flavors, you then have the choice to add between zero and three toppings from a selection of six toppings. Unlike the flavors, the order in which you add the toppings does not matter.

To calculate the number of possible combinations, we need to use the concept of permutations.

For the ice cream flavors, since order matters, we can use the permutation formula. The number of ways to choose two flavors from eight is given by P(8, 2) = 8! / (8-2)! = 8! / 6! = 8 x 7 = 56.

For the toppings, since the order does not matter, we can use the combination formula. The number of ways to choose between zero and three toppings from six is given by the sum of C(6, 0) + C(6, 1) + C(6, 2) + C(6, 3) = 1 + 6 + 15 + 20 = 42.

To find the total number of combinations, we multiply the number of flavor combinations by the number of topping combinations: 56 x 42 = 2,352.

Therefore, there are 2,352 possible combinations of two ice cream flavors and between zero and three toppings at the ice cream shop.

The homogeneous system of linear equations has a solution space with a basis of {(1, 2, -1)}. The dimension of the solution space is 1.

To find a basis for the solution space of the given homogeneous system of linear equations, we need to solve the system and express the solutions in terms of a linear combination of vectors.

The system of equations is as follows:

Equation 1: -x + y - z = 0

Equation 2: 2x - y = 0

Equation 3: 2x - 3y - 4z = 0

We can start by using the equations to eliminate variables. From Equation 2, we can express y in terms of x as y = 2x. Substituting this into Equation 1 gives us -x + 2x - z = 0, which simplifies to x - z = 0. Rearranging this equation, we have x = z.

Now, we can express the variables in terms of a single parameter. Let's choose z as the parameter. Thus, x = z and y = 2x = 2z.

Now, we can express the solutions in vector form as (x, y, z) = (z, 2z, z) = z(1, 2, 1). This means that the solution space is spanned by the vector (1, 2, 1).

To find the basis for the solution space, we need to check if the vector (1, 2, 1) is linearly independent. Since it is the only vector spanning the solution space, it is linearly independent. Therefore, the basis for the solution space is {(1, 2, 1)}.

The dimension of the solution space is equal to the number of vectors in the basis, which in this case is 1. Therefore, the dimension of the solution space is 1.

Parametric estimating is a valuable technique in project management that can save time and resources by using historical data to establish a statistical relationship and estimate the scope, cost, and duration of a project. (option d).

Estimating techniques are used in project management to calculate an estimate for the scope, cost, and duration of a project.

The keyword to note here is "statistical relationship". In parametric estimating, this relationship is established by analyzing historical data and identifying patterns and trends. Once a relationship has been established, it can be used to estimate the scope, cost, and duration of a similar project in the future.

Similarly, in software development, the lines of code can be used as a variable to establish a statistical relationship. By analyzing the historical data of similar projects, a relationship can be established between the lines of code and the duration of the project.

Hence the correct option is (d).

Answer:

18 and 42 are both multiples of 6, and when I add them, I also get a multiple of 6:

18+42=60.

Explain to Nina why adding two multiples of 6 will always result in another multiple of 6.

Step-by-step explanation:

18 and 42 are both multiples of 6 which means 6 is a factor of both numbers.

6⋅3=18

6⋅7=42

Solution_1_82d819495d2abc4f1edf4f9286349041

When you add 18 and 42, you can use the distributive property to show that the sum is also a multiple of 6:

6⋅3+6⋅7=6⋅(3+7)=6⋅10

This is due to the distributive property of addition of numbers.

It is given that while finding multiples of 6 , Nina got that 18 and 42 are both multiples of 6, and when she add them, she again get's a multiple of 6.

We have to explain the reason behind this.

What is the distributive property of addition ?

This is given by ; a × ( b + c ) = ( a + b ) × c .

As per the question , 18 and 42 are multiples of 6 which meant 6 is a factor of both numbers , i.e.,

6 × 3 = 18

6 × 7 = 42

While adding these two numbers we can use distributive properties to show that sum is also a multiple of 6.

6 × 3 + 6 × 7 = 6 × ( 3 + 7 ) = 6 × 10

Assume , if a & b are two multiples of 6 , then ;

6 × a

6 × b

When we add them ;

6 × a + 6 × b = 6 × ( a + b )

here ; a and b are whole numbers.

Thus , if we use distributive property , the sum of two multiples of any whole number is always a multiple of that number.

A model's scale ratio is the ratio of linear dimensions. The scale factor of the triangle is (1/2).

A model's scale ratio is the proportionate ratio of a linear dimension of the model to the equivalent characteristic of the original.

The scale ratio of the triangle can be found by taking the ratio of any one side of the dashed triangle to the solid triangle. Therefore, the scale ratio will be,

\(\rm Scale\ ratio = \dfrac{\text{Length of the dashed line}}{\text{Length of the solid line}}\\\\ Scale\ ratio = \dfrac{2}{4} = \dfrac{1}{2}\)

Hence, the scale factor of the triangle is (1/2).

17.5ft

3*7ft

=

21ft

So we know the room is 21ft by 17.5ft

In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .

= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )

= 25 + 25 = x²

= 50 = x²
