Answer 1

Substitution method - the points are (-6, -11/2),(-4,-3), (-8/5,0), (0,2) and (4,7)

what is the substitution method?

To solve many simultaneous linear equations, use the substitution method in algebra. The value of a variable from one equation is substituted in the second equation in this procedure, as the name implies.

we are given the equation,

5x - 4y = -8

case I

when x = -6

5(-6) - 4y  = -8

-30 - 4y = -8

-4y = -8 + 30

-4y = 22

y = -(22/4)

y = -11/2

(x,y) = (-6, -11/2)

case II

when y = -3

5x - 4(-3) = -8

5x + 12 = -8

5x = -8 -12

5x = -20

x = -20/5

x = -4

(x,y) = (-4,-3)

case III

when y = 0

5x - 4y = -8

5x - 4(0) = -8

5x = -8

x = -8/5

(x,y) = (-8/5,0)

case III

when x = 0

5(0) - 4y = -8

0 - 4y = - 8

y= 8/4

y = 2

(x,y) = (0,2)

case IV

when x = 4

5(4) - 4y = -8

20 - 4y = -8

-4y = -8-20

-4y = -28

y = 28/4

y = 7

(x,y) = (4,7)

Intelligence Quotient (IQ) scores are often reported to be normally distributed with μ=100.0 and σ=15.0. A random sample of 61 people is taken.What is the probability that the mean IQ score of people in the sample is less than 98? Round your answer to 4 decimal places, if necessary.

Answers

To find the probability that the mean IQ score of people in the sample is less than 98, first we need to convert the value into z-score by using the formula:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Then, when x=98:

[tex]\begin{gathered} z=\frac{98-100.0}{15.0} \\ z=\frac{-2.0}{15.0} \\ z=-0.1333 \end{gathered}[/tex]

By checking in a standard normal table z=-0.1333 has a p-value=0.4471.

Then the probability is 0.4471 that also can be expressed as 44.71%

Answers

The difference of population in these two cities are 85900- 3200

= 82,700

How do you calculate difference?


Subtract the largest number from the lowest number to determine the difference between two integers. The difference between the two numbers is the product of this sum. As a result, there are 55 between the numbers 45 and 100.

Given: Population of city A= 8.59 x 10^4

and population of city B = 3.2 x 10^3

This can also be written as :

Population of city A= 85,900

and population of city B = 3200

Thus the difference of population in these two cities are 85900- 3200

= 82,700

Jane wants to buy a CD for $12. She has saved $7. How much money does she still need if 6% sales tax will be added to the cost of the CD.

Answers

Using the sales tax, the amount of money she still needs is $5.72

What is sales tax?

A sales tax is a consumption tax imposed by the government on the sale of goods and services.

Jane wants to buy a CD for $12. She has saved $7.

The amount she needs if 6% sales tax is added to the cost can be calculated as follows;

Let's find the sales tax,

sales tax = 6% of 12

sales tax = 6 / 100 × 12

sales tax = 72 / 100

sales tax = $0.72

Therefore,

amount she needs to save = 12 + 0.72 - 7

amount she needs to save = 12.72 - 7

Answer:

a. [tex]y = 21.5x + 376[/tex]

b. [tex]569.5[/tex] or with rounding, [tex]570[/tex].

Step-by-step explanation:

To set up a linear equation in slope-intercept form, we use the formula y=mx+b, where m is slope given by the formula m= [tex]\frac{y_{2}-y_1 }{x_2-x_1}[/tex], and b is the y-intercept (the value of y when x=0). It is given that x is the year, where 2005 is x=0, and y is the number of assistants in thousands, meaning at x=0 (the year 2005), y=376 (376,000 medical assistants). This can be written as the point (0, 376), which is our y-intercept. Using the formula for slope, the slope of this line is found to be [tex]\frac{215}{10}[/tex], or 21.5 ([tex]\frac{591-376}{10-0}[/tex]). This gives us the equation [tex]y = 21.5x + 376[/tex].

For part (b), simply plug in a value for x, then solve for y. The given value is the year 2014, which can be written as x=9 (x=0 is 2005, x=1 is 2006, etc.). This gives us the equation [tex]y=21.5(9)+376[/tex], which gives us y=569.5. However, since this is a real-world problem, you can not have "half" a person, so this rounds up to 570.

Angles and properties of plane shapes

To answer this question, let us recall the following:

The diagonals of a rectangle bisects each other into four eqaul length.The base angles of an Isosceles triangle are equal.Complementary angles add up to give a total of 90°.

Hence;

the lengths RV and SV are

so, 3x+8=6x-4

6x-3x=8+4 [collecting like terms]

3x=12

when we divide both sides of the equation by 3, we have the value of x=4.

the angles VRS and VRU are complementary

so, 54°+VRU = 90°

VRU = 90°-54°

VRU = 36°

The triangle RUV is an Isosceles

so, angles VRU and VUR are equal, therefore angle VUR = 36°.

The system of equations has two solutions, these are:

(-0.89, 2.33) and (1.4, 9.2)

How to solve the system of equations?

Here we have the following system of equations:

y = 3x + 5

y = 4x² + x

We can see that y is already isolated in both equations, so we can write the equation:

3x + 5 = y = 4x² + x

3x + 5 = 4x² + x

now we can solve this for x, this is just a quadratic equation:

3x + 5 - 4x² - x = 0

-4x² + 2x + 5 = 0

Using the quadratic formula, we can see that the two solutions are:

[tex]x = \frac{-2 \pm \sqrt{2^2 - 4*(-4)*5} }{2*-4} \\\\x = \frac{-2 \pm 9.17}{-8}[/tex]

So the solutions are:

x = (-2 +9.17)/-8 = -0.89

x = (-2 - 9.17)/-8 = 1.4

Evaluating the linear equation in these values, we get:

y = 3*(-0.89) +5 = 2.33

y = 3*(1.4) + 5 = 9.2

So the solutions of the system are:

(-0.89, 2.33) and (1.4, 9.2)

The single inequality y > |x + 2| is equivalent to:

4. y > x + 2

y < –x – 2

What is an inequality?

It should be noted that an inequality is simply used to show the relationship between the expressions that aren't equal.

The non-negative value of a real number x, regardless of its sign, is its absolute value or modulus | x |. For instance, 5 has an absolute value of 5, and 5 has a value of 5. One way to think about a number's absolute value is as its distance from zero on the real number line.

It should be noted that based on the information, the inequality is:

y > |x + 2|. This is the positive part of the modulus.

This is the same as y < –x – 2 when the signs are changed. This is the negative part of the modulus.

In conclusion, the correct option is 4.

Games Throughout History Board games are great to play with friends. One of the most popular games, checkers, was invented centuries ago.History of Checkers By 1400 B.C., people living in Egypt were playing a game called Alquerque using a board and small round pieces. Alquerque spread all over the world. Then, in 1100 A.D., a man in France decided to play the game on a chessboard with 12 pieces for each player. The game later became known as checkers in North America.Rules of the Game People began writing books about the game of checkers. Over time, the rules were changed, and new rules were added. Now, there are different sets of rules for the game, but the basic ones are the same. One player has 12 white checkers, and the other player has 12 red checkers. The pieces are placed on two rows at each end of the board, and the player with red checkers moves first. Each player tries to get all of their pieces to the opposite end of the board. One player can also jump over another players piece and capture it if the diagonal space on the other side of it is open. Once a checker has reached the top row of the opposite end of the board, it becomes a king. Kings can move backward or forward across the board. The first player to capture all of the other players checker pieces wins the game.Checkers Tournaments The American Checkers Federation (ACF) organizes checkers tournaments in the United States. It also sponsors a national checkers tournament for adults and a tournament for children each year. This organization has more than 500 members who can play in any tournament in the country.An International Pastime Checkers has different names in other countries. In England and Australia, the game is called draughts. Some of the rules also change depending on where the game is played. In one version, for example, the flying king can move more than one space at a time. When the game is played in Germany and Italy, only kings can jump over and capture other kings. No matter what it is called, checkers has become a pastime for all people. Which is the best summary of this passage? A. Thousands of years ago, the game of checkers was called Alquerque, but it later came to be known as checkers in North America. The game is played on a black-and-white chessboard.
