-3x2 (xy+2x2) + 7x4 -3x3(5y + x)??

allochka39001 [22]

Answer:

−2x4−18x3y

Step-by-step explanation:

Let's simplify step-by-step.

(−3x2)(xy+2x2)+7x4−3x3(5y+x)

Distribute:

=(−3x2)(xy)+(−3x2)(2x2)+7x4+−3x4+−15x3y

=−3x3y+−6x4+7x4+−3x4+−15x3y

Combine Like Terms:

=−3x3y+−6x4+7x4+−3x4+−15x3y

=(−6x4+7x4+−3x4)+(−3x3y+−15x3y)

=−2x4+−18x3y

Bank A charger a 4$ service fee and $0.25 for each check written. Bank B charges $5 and $0.20 for each check written . How many

Andre45 [30]

1. A person would need to write 20 checks each month for the two banks to charge the same amount in fees.
2. The account from Bank A would cost less if a person were to write 10 checks in a month.

Explanation:
1. Bank A = 0.25x + 4, Bank B = 0.2x + 5

0.25x + 4 = 0.2x + 5
0.05x = 1
x = 20

2. Bank A = 0.25(10) + 4 = $6.5
Bank B = 0.2(10) + 5 =$7
Therefore, it would cost less to write 10 checks from Bank A.

Create a visual plot of the data in the table by constructing a bar graph.

sashaice [31]

The average view of the dress code is that this dress is not good

<h3>Explain how Rashad could collect data to ensure that it is a random sample of the population.</h3>

For Rashad's sample to be a random sample gotten from the population, the following must be considered.

First, he must have a defined population. In this case, his population is all the students in his high school (non students are not to be considered)
Next, he must have a defined sample size (say 10% or 20% of the total number of students in the school)
Next, he must select students at random (a perfect example of this is one of every five or ten students that enters the school gate.
Lastly, he must collect data for his sample

<h3>Create a visual plot of the data in the table by constructing a bar graph.</h3>

To do this, we simply create a bar graph.

The response would go into the x-axis, while the number of people would go into the y-axis

See attachment for bar graph

<h3>What is the average view of the dress code? How did you come to this conclusion?</h3>

The average view of the dress code is that this dress is not good

It is considered the average view of the dress code because it is the opinion with the most frequency

<h3>Will the dress change?</h3>

The number of students that do not like the dress as:

210 + 206 + 770 = 1186

Their percentage is

Percentage = 1186/(210 + 206 + 770 + 358)

Percentage = 77%

This means that

Yes, the dress will change
