Answer:

\(\boxed{\sf -14-4i}\)

Step-by-step explanation:

\(\sf (-2i)(2-7i)\)

Multiply -2i * 2-7i:-

\(\sf -2i\times 2-2(-7)i^2\)

i^2 is -1

\(\sf -2i\times 2-2(-7)(-1)\)

Now, do the multiplications.

Reorder the terms.

\(\sf -14-4i\)

Given information:

Raoul collects sports cards.

He has six baseball cards, three football cards, four hockey cards, and three basketball cards.

Raoul has a total of 6 + 3 + 4 + 3 = 16 sports cards.

The number of hockey cards he has is 4.

Therefore, the fraction of his sports cards that are hockey cards is:

4/16

Simplifying the fraction by dividing both the numerator and denominator by 4, we get:

1/4.

So, 1/4 of Raoul's sports cards are hockey cards.

Answer:

Y(4) = 200(1.1)^4

Step-by-step explanation:

Given that :

Number of tickets purchased before consecutive wins = 200

For each consecutive win, ticket purchased increases by a factor of 1.1

Number of tickets after 4 wins

This scenario describes an exponential relation :

Where increase is factor based and not a certain number :

Hence,

Number of tickets, Y= Initial number of ticket * growth factor^number of wins

Hence, we have

Y(n) = 200(1.1)^n

Y(4) = 200(1.1)^4 = 292.82

The given information states that a 6-foot piece of ribbon costs $7.20. To find the price per inch, we need to convert the measurements and calculate the cost per inch.

To calculate the price per inch of the ribbon, we need to convert the measurements to a consistent unit. Since the price is given in dollars and the length is given in feet, we need to convert feet to inches.

Since there are 12 inches in 1 foot, we can multiply the length of the ribbon in feet by 12 to obtain the length in inches. In this case, 6 feet is equal to 6 * 12 = 72 inches. Next, we divide the total cost of the ribbon by the length in inches to find the price per inch. In this case, we divide $7.20 by 72 inches:

Price per inch = $7.20 / 72 = $0.10

Therefore, the price per inch of the ribbon is $0.10.

In summary, to find the price per inch of a 6-foot piece of ribbon that costs $7.20, we convert the length to inches and divide the total cost by the length in inches. The resulting price per inch is $0.10.

Option 2

Step-by-step explanation:

Using point-slope form, the line passes through (3, 1).

Option 2 is the only choice that satisfes this.

____________________________________

\( \large \tt Solution \: : \)

The equation is given in its point slope form :

\(\qquad \tt \rightarrow \:y - 1 = \dfrac{2}{3} (x - 3)\)

And the general equation in point slope form is :

\(\qquad \tt \rightarrow \:y - y_1 = m(x - x_1)\)

by comparing these two, we can get

And \({ (x_1 , y_1) } \) satisfies the equation, so the line (graph) of this equation should have point (3 , 1) lying on it.

And the only graph satisfying this condition is graph 2, therefore The graph 2 is the required graph.

The ratio of 3:4 for 363 days is equivalent to the ratio of 1.05:1.40.

To find the equivalent ratio for 363 days in the ratio of 3:4, we can use the following steps:

Step 1: Add the ratio terms (3 + 4 = 7) to get the total number of parts.

Step 2: Divide the total number of parts by the denominator of the ratio (7 ÷ 4 = 1.75).

Step 3: Multiply the numerator and denominator of the ratio by the result from Step 2 to get the equivalent ratio.

Therefore, the equivalent ratio of 3:4 for 363 days is:

3 : 4 = 3/7 x 1.75 : 4/7 x 1.75

= 1.05 : 1.40

We have proved that, by using element method of proof, for all sets A, B, and C, if A ⊆ B and B ⊆ C, then A ⊆ C.

To prove that for all sets A, B, and C, if A ⊆ B and B ⊆ C, then A ⊆ C using the element method of proof, we'll follow these steps:

1. Assume that A ⊆ B and B ⊆ C. This means that every element in A is also in B, and every element in B is also in C.
2. Let x be an arbitrary element of A. Our goal is to show that x must also be an element of C.
3. Since A ⊆ B, we know that x ∈ A implies x ∈ B.
4. Now, we also know that B ⊆ C, so x ∈ B implies x ∈ C.
5. Therefore, since x ∈ A implies x ∈ C, we can conclude that A ⊆ C.

In summary, we have proved that for all sets A, B, and C, if A ⊆ B and B ⊆ C, then A ⊆ C using the element method of proof.

Could you write the problem right? I don't get it tell me when it right and i can factor it.

Step-by-step explanation:

Since the p-value for a one-sided test of the null hypothesis H0: μ = 15 is 0.03, we can reject H0 at the 5% level of significance but not at the 1% level.

The purpose of a hypothesis is to discuss a notion or assumption and see if it might be true. Before conducting any pertinent research—aside from a basic background review—the hypothesis is formulated using the scientific process.

(a) For a 99% confidence interval, the level of significance is 1% (α = 0.01), which is less than the given p-value of 0.03. Therefore, we cannot reject the null hypothesis at the 99% confidence level, and we conclude that the 99% confidence interval for μ does include 15.

(b) For a 95% confidence interval, the level of significance is 5% (α = 0.05), which is greater than the given p-value of 0.03. Therefore, we can reject the null hypothesis at the 95% confidence level. This means that the 95% confidence interval for μ does not include 15.

In summary, the 99% confidence interval includes 15, while the 95% confidence interval does not include 15. This makes sense, as the p-value of 0.03 indicates that the evidence against the null hypothesis is not very strong, but it is still significant at the 5% level.

Therefore, a wider confidence interval (with a higher level of confidence) will include the null hypothesis value, while a narrower confidence interval (with a lower level of confidence) will not.

If a square pyramid is sliced in a way that the plane cuts in a direction perpendicular to the base but doesn't pass through the vertex, the resulting cross-section will be a trapezoid.

This trapezoid will have one pair of parallel sides and one pair of non-parallel sides.

To understand why the resulting cross-section is a trapezoid, imagine a square pyramid standing on its base. Now, imagine slicing the pyramid horizontally, parallel to the base. The resulting cross-section would be a square.

However, if we change the direction of the slice to be perpendicular to the base, but not passing through the vertex, the resulting cross-section will not be a square. Instead, it will be a trapezoid, with one set of parallel sides corresponding to the base of the pyramid, and the other set of sides corresponding to the slice that was made.

This type of cross-section is commonly seen in architectural and engineering designs, where different shapes need to be created by slicing or intersecting 3D shapes. Understanding the resulting cross-section of different slicing techniques is essential to ensure the proper fit and function of the final product.

The approximate values of the non-integral roots of the polynomial equation are -5.57, -1.95, 0.21, 1.27, and 4.73. These values represent the values at which the polynomial equation evaluates to zero, indicating the roots of the equation.

To find the roots of a polynomial equation, we set the equation equal to zero and solve for the unknown variable. In this case, we have a polynomial equation with non-integral roots.

To obtain the approximate values of these roots, numerical methods such as iterative methods or numerical approximation techniques can be used. These methods involve making educated guesses and refining the guesses until the equation evaluates to zero.

The resulting approximate values for the non-integral roots of the polynomial equation are -5.57, -1.95, 0.21, 1.27, and 4.73. These values are not exact, but they are close approximations to the actual roots of the equation.
