If the money supply increases and nominal GDP remains the same, then A. price level increases.

<h3>What is Money Supply?</h3>

This refers to the total amount of money that is in circulation in a country that usually increases spending.

Hence, an open market sale by the federal reserve will increase the interest rates because it would increase investment spending because an OMO sale decreases interest rates which make getting loans easier.

M= Money supply

V= Velocity

P- Price level

Y= nominal GDP

Hence, with the increase in the money supply, then there would be an increase in the price supply.

What is the rationale behind document 1 (usability testing)?

gladu [14]

The rationale behind usability testing is that getting input from real users at the beginning of a project is essential to the design process.

<h3>What is the rationale behind usability testing?</h3>

The primary aim of a usability test is so as to make better a design.

Note that in any usability test, real users are made to try and cary out or accomplish some goals, or tasks, via the use of a product under some controlled conditions.

Therefore, The rationale behind usability testing is that getting input from real users at the beginning of a project is essential to the design process.

Explain in detail, how you solved the following problem: The first two terms of a sequence are 10 and 20. If each term after the

KIM [24]

Answer:

$T_{2020} = 15$

Explanation:

Given

$T_1 = 10$

$T_2 = 20$

Each term after the second term is the average of all of the preceding terms

Required:

Explain how to solve the 2020th term

Solve the 2020th term

Solving the 2020th term of a sequence using conventional method may be a little bit difficult but in questions like this, it's not.

The very first thing to do is to solve for the third term;

The value of the third term is the value of every other term after the second term of the sequence; So, what I'll do is that I'll assign the value of the third term to the 2020th term

<em>This is proved as follows;</em>

From the question, we have that "..... each term after the second term is the average of all of the preceding terms", in other words the MEAN

$T_{n} = \frac{\sum T{k}}{n-1} ; where: k = 1 .... n -1$

<em>Assume n = 3</em>

$T_{3} = \frac{T_1 + T_2}{2}$

<em>Multiply both sides by 2</em>

$2 * T_{3} = \frac{T_1 + T_2}{2} * 2$

$2T_{3} = T_1 + T_2$

<em>Assume n = 4</em>

$T_{4} = \frac{T_1 + T_2 + T_3}{3}$

$T_{4} = \frac{(T_1 + T_2) + T_3}{3}$

Substitute $2T_{3} = T_1 + T_2$

$T_{4} = \frac{2T_3 + T_3}{3}$

$T_{4} = \frac{3T_3}{3}$

$T_{4} = T_3$

Assume n = 5

$T_{5} = \frac{T_1 + T_2 + T_3 +T_4}{4}$

$T_{5} = \frac{(T_1 + T_2) + T_3 +(T_4)}{4}$

Substitute $2T_{3} = T_1 + T_2$ and $T_{4} = T_3$

$T_{5} = \frac{2T_3 + T_3 +T_3}{4}$

$T_{5} = \frac{4T_3}{4}$

$T_{5} = \frac{(5-1)T_3}{5-1}$

<em>Replace 5 with n</em>

$T_{n} = \frac{(n-1)T_3}{n-1}$

<em>(n-1) will definitely cancel out (n-1); So, we're left with</em>

$T_{n} = T_3$

Hence,

$T_{2020} = T_3$

Calculating $T_3$

$T_{3} = \frac{10 + 20}{2}$

$T_{3} = \frac{30}{2}$

$T_{3} = 15$

Recall that $T_{2020} = T_3$

$T_{2020} = 15$

Somewhat fair. Not really from the different POV from now and then. But from the people of pasts understanding they may have thought what we do now was wrong. But I think some things we have done in the past has made America what it is today. There is not much judgement from it because there’s not much we can do to change the pay
