Answer 2
Answer:

[tex]\large\boxed{\boxed{\pink{\bf \leadsto (-2,2) \ is \ the \ solution \ of \ the \ given \ linear \ equations .}}}[/tex]

Step-by-step explanation:

Given to equations to us are ,

[tex]\qquad \red{\bullet} \: y = x + 4 \\\\\qquad \red{\bullet} \: y = -2x - 2 [/tex]

And we need to find the solution using graphical method.

So , after plotting the graph of both equations the point where both lines intersect will be the solution of the graph.

And , for plotting we need at least two points .

For equation (1) :-

[tex]\implies y = x + 4 [/tex]

When x = (-4) .

[tex]\implies y = -4+4\\\\\bf\implies y = 0 [/tex]

When x = (-3)

[tex]\implies y = -3+4\\\\\bf\implies y = -1 [/tex]

[tex]\large\boxed{\begin{tabular}{|c|c|c|} \cline{1-3} \bf x & (-4) & (-3) \\\cline{1-3} \bf y & 0 & 1 \\\cline{1-3}\end{tabular}}[/tex]

For equation 2 :-

[tex]\implies y = -2x - 2 [/tex]

When x = (-1) .

[tex]\implies y = -2(-1)-2\\\\\bf\implies y = 0 [/tex]

When x = (0)

[tex]\implies y = 0-2\\\\\bf\implies y = -2 [/tex]

[tex]\large\boxed{\begin{tabular}{|c|c|c|} \cline{1-3} \bf x & (-1) & 0 \\\cline{1-3} \bf y & 0 & -2 \\\cline{1-3}\end{tabular}}[/tex]

Now , let's plot their graphs. Graph is in attachment. Hence on plotting the graph we see that both the lines Intersect on (-2,2) . Hence x = -2 and y = 2 is the solution of the given linear equation.

Hence (-2,2) is the solution of the given pair of linear equations in two variables.

solve the equation: the booster club of the baseball team bought pizza to sell at a concession stand. the school donated three pies to the sale. each pie was then cut into 8 pieces and sold . there were a total of 64 pieces to sell. how many pies did the booster club purchase

Answers

Answer:

Booster club purchased 5 pies.

Step-by-step explanation:

Let the number of pies purchased by booster club be represented by n. The school also donated 3 pies to sell.

So that,

Total number of pies = n + 3

Given that there was 64 pieces of pies to sell after cutting each pie into 8 pieces.

Thus,

8( n + 3) = 64

8n + 24 = 64

8n = 64 - 24

8n = 40

Divide both sides by 8 to have,

n = 5

The number of pies purchased by booster club is 5.

Michael has been saving his money and wants to invest it. After doing some research, he has decided to invest $20,000 into a Certificate of Deposit. The interest rate on the CD is 3% with a term of five years, and the interest is paid out annually. Based on recent inflation, Michael is planning on an annual inflation rate of 2%. How much interest will Michael earn on this CD in the first year, based on the real interest rate? $200 $600 $1,000 $1,400


IT IS NOT $600!!! THE CORRECT ANSWER IS $200 ON EDGE2020

Answers

Answer:

Interest earned= $200

Step-by-step explanation:

Giving the following information:

Initial investment= $20,000

Interest rate= 3%

Inflation rate= 2%

First, we need to calculate the real interest rate. The inflation rate decreases the value of money through time. We need to deduct from the interest rate, the inflation rate.

Real interest rate= 0.03 - 0.02= 0.01

Now, we can calculate the interest earned in year 1:

Interest earned= PV*(1+i)^n - PV

Interest earned= 20,000*(1.01^1) - 20,000

Interest earned= $200

Kenny is ordering uniforms for both the girls' and boys' tennis clubs. He is ordering shirts for 43 players and two coaches at a total cost of $658.35. Additionally, he is ordering visors for each player at a total cost of $368.51. How much with each player pay for the shirt and visor?

Answers

Answer: 23.20 dollars

Cost for 1 shirt = $14.63

Cost for 1 visor = $8.57

Total = 14.63+8.57 = 23.20

==============================================================

Explanation:

s = cost of 1 shirt

v = cost of 1 visor

costs are in dollars

There are 43 players and 2 coaches that get a shirt. There are 43+2 = 45 people total that get a shirt. The amount of money spent on all the shirts is 45s because we multiply the number of people (45) with the cost per shirt (which is s). Set this equal to 658.35 and solve for s

45s = 658.35

s = 658.35/45

s = 14.63

Each shirt costs $14.63, and this is the amount each player should pay.

-------------------

Kenny is also ordering 43 visors. The total cost here is 368.51 dollars. This means the equation we need to solve is 43v = 368.51

Divide both sides by 43 to isolate v

43v = 368.51

v = 368.51/43

v = 8.57

Each visor costs $8.57, and this is the amount each player should pay.

-------------------

Add up the two costs we found and we get 14.63+8.57 = 23.20, which is the total cost each player must pay for both a shirt and a visor.

Sum of interior angle of an n-polygon = (n - 2)*180

The polygon given is pentagon with 5 sides.

Sum of the polygon = (5 - 2)*180 = 540°

Therefore, sum of all its interior angles would be:

5x + 150 + (3x - 30) + 70 + (2x - 50) = 540°

Solve for x

5x + 150 + 3x - 30 + 70 + 2x - 50 = 540

Collect like terms

5x + 3x + 2x + 150 - 30 + 70 - 59 = 540

10x + 140 = 540

10x = 540 - 140 (Subtraction property of equality)

The length of a cell phone is
1.4 inches and the width is
4.4 inches. The company making the cell phone wants to make a new version whose length will be
1.75 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?

Answers

Answer:

The width of new phone = 5.5 inches

Step-by-step explanation:

Given that:

Length of cell phone = 1.4 inches

Width of cell phone = 4.4 inches

Ratio of length to width = 1.4 : 4.4

Length of new version = 1.75 inches

Width of new version = x

Ratio of length to width = 1.75 : x

As the relation is proportional;

[tex]1.4:4.4 ::1.75:x[/tex]

Product of mean = Product of extreme

4.4 * 1.75 = 1.4x

7.7 = 1.4x

1.4x = 7.7

Dividing both sides by 1.4

[tex]\frac{1.4x}{1.4}=\frac{7.7}{1.4}\\x=5.5\\[/tex]

Hence,

The width of new phone = 5.5 inches

The correlation coefficient for the data is 0.93 and this can be determined by using the formula of the correlation coefficient.

Given :

The table shows data collected from 14 people.

A statistical measure of the strength of the relative movement between two variables is known as the correlation coefficient.

The formula of the correlation coefficient is given by:

[tex]\rm r = \dfrac{\sum (x_i-\bar{x})(y_i-\bar{y})}{\sqrt{\sum(x_i-\bar{x})^2\sum(y_i-\bar{y})^2} }[/tex]

where r is the correlation coefficient, [tex]\bar{x}[/tex] is the mean of the values of the x variable, [tex]x_i[/tex] values of the x-variable in the sample space, [tex]y_i[/tex] values of the y-variable in a sample space, and [tex]\bar{y}[/tex] is the mean of the values of the y-variable.

Now, from the attached table substitute the values of the known terms in the above formula.

[tex]\rm r = \dfrac{35.4464286}{\sqrt{(19.23214289)\times (76.08928571)} }[/tex]

Simplify the above expression.

[tex]\rm r = \dfrac{35.4464286}{38.25388889} }[/tex]

r = 0.93

So, the correlation coefficient for the data is 0.93.
