Laura needs to buy chips and soda for the guests at her party. Each large bag of chips cost $2.40 and each large bottle of soda cost $2.00. She has $48.00 to spend. Part A Create an inequality using two variables to represent this situation. Be sure to explain the meaning of each variable.Part B Which of the following graphs represent the number of chips and soda bottles that Laura can buy? Part C Which combination of bottles of soda and bags of chips can Laura buy?

Answers

Part A.

To write the inequality we have to introduce variables that represent the things Laura needs to buy. For this reason let x be the number of sodas she buys and let y be the number of chips she buys.

Now, we know that each bag of chips cost $2.40 then tha ammount she spends in chips will be

[tex]2.4y[/tex]

Following the same reasoning, the ammount she spends in sodas will be

[tex]2x[/tex]

The total ammount she spends will be the sum of each ammount, that is:

[tex]2x+2.4y[/tex]

Finally, we know that Laura has $48, so she can only spend less or equal this ammount.

Therefore the inequality representing this situation is

[tex]2x+2.4y\leq48[/tex]

Part B.

To graph this inequality, first we have to graph the line given by

[tex]2x+2.4y=48[/tex]

Doing this we obtained the following graph

Now we need to decide which semi plane represent the solution set of the inequality. Since we have a less or equal sign the right choice is the left one, then the graph of the inequality is

Therefore the graphs representing the number of chips and soda bottles Laura can buy is option B.

Part C.

To determine which combination of bottles of soda and chips Laura can buy we can graph the options we have. Remember that the x-axis represents the soda and the y-axis the chips. Hence the option we have will be equivalent to the points (4,24), (12,8), (16,8) and (28,4). Graphing this points we have

The only option allowed is the one that lies within the shaded region, therefore Laura can buy 12 bottles of soda and 8 bags of chips.

On a standardized test, the mean is 38 and the standard
deviation is 4.5. Approximately what percent of the scores
fall in the range 29-47?

Answers

The percentage of scores that fall in the range 29-47 is of 95%.

Empirical Rule

The Empirical Rule states that, for a normally distributed random variable:

The percentage of scores within one standard deviation of the mean is 68%.The percentage of scores within two standard deviations of the mean is 95%.The percentage of scores within three standard deviations of the mean is 99.7%.

In the context of this problem, the mean and the standard deviation of scores are given as follows:

Mean = 38.Standard deviation = 4.5.

Hence the range of 29 to 47 is within two standard deviations of the mean, as 38 - 2 x 4.5 = 29 and 38 + 2 x 4.5 = 47, meaning that the percentage of scores that fall in the range is of 95%.

What is the area of a triangle?
The territory a triangle occupies inside its three sides or limits is known as its area. A triangle's sides determine its area. In essence, the length and base of the rectangle multiplied together with 0.5 gives the area of the triangle.
Mathematically, Area of a triangle = 0.5*height*base = 0.5*h*b -(ii)

Given, the length of the rectangle = l = 8 m
The breadth of the rectangle = b = 13 m
Area of the rectangle = 8*13 = 104 m² [Using (i)]
Also, the base of the triangle = b = 13 - 4 -4 = 5 m
The height of the rectangle = h = 6 m
Area of the triangle = 0.5*5*6 = 15 m²

Answers

Answer:

x = -2

Explanation:

The initial expression is:

10( x + 3) - ( -9x - 4) = x - 5 + 3

To solve for x, we first need to apply the distributive property as:

10x + 10(3) -(-9x) - (-4) = x - 5 + 3

10x + 30 + 9x + 4 = x - 5 + 3

Then, add the like terms to get:

(10x + 9x) + (30 + 4) = x + (-5 + 3)

19x + 34 = x - 2

Subtract x from both sides:

19x + 34 - x = x - 2 - x

18x + 34 = -2

Subtract 34 from both sides:

18x + 34 - 34 = -2 - 34

18x = -36

Finally, divide both sides by 18:

18x/18 = -36/18

x = -2

Therefore, the answer is x = -2

The equation to find the constant of proportionality or k is?

2K = Y + X

Y = 2K + X

None of the above

K = Y / X

Answers

The equation to find the constant of proportionality or k is K=Y/X.

The value of the ratio between two proportional quantities, known as the constant of proportionality, is constant. When the product or ratio of two changing amounts gives a constant, that relationship is said to be proportionate. Depending on the kind of proportion between the two specified quantities—direct variation or inverse variation—the proportionality constant's value will vary.

When two variables are proportional to one another either directly or indirectly, their relationship can be expressed as y = kx or y = k/x, where k specifies how the two variables are related to one another. This k is referred to as the proportionality constant.

Hence the equation  to find the constant of proportionality or k is

K = Y/X

A car rental company charges $15 per day and $0.55 per kilometer to rent a car. What is the total bill if a car is rented for 4 days and is driven 146 kilometers? Andy how would I solve it

Answers

Answer:

$140.30

Step-by-step explanation:

The best way to solve this is to make an equation.  

y = 15x + 0.55k

In simple terms this is:

Total = $15(number of days) + $0.55(Number of kilometers)

Plug in the values

15(4) + 0.55(146)

60 + 80.3

140.3

Since this is dollars it would $140.30!

Hope this explanation was good enough.  

Answer: $140.30 is the total bill

Step-by-step explanation:

First, you would time 15 by 4 to get the price for the number of days you have rented the car. Which is $60

Now times $0.55 by 146 to get the price for the kilometers you have driven. Which is $80.30

Add both $60 and $80.30

The total bill is $140.30

True, 0.5 is the coefficient of v² in the expression v + 0.5v².

What is a Coefficient?A coefficient is a number or quantity related to a variable. It is usually an integer multiplied by the variable and displayed next to it. Variables that do not have a numerical value are assumed to have a coefficient of one. A coefficient might be positive or negative, real or imaginary, and expressed in decimals or fractions.

Given expression is v + 0.5v².

Follow the methods below to find the coefficient of a variable in a term:

Step 1: Encircle the variable and its power whose coefficient we're looking for.

If you are dealt 4 cards from a shuffled deck of 52 cards, find the probability of getting two queens and two kings.

Answers

If you are dealt 4 cards from a shuffled deck of 52 cards, the probability of getting two queens and two kings is:  0.000133.

Probability

Number of ways to get two of the four queens = 4C2 = 6 ways

Number of ways to get  two of the four kings =  4C2 = 6 ways

Number of ways to get none of the deck = 48C0 = 1 way

Hence,

Number of  ways to get four cards  = 6 x 6 x 1

Number of  ways to get four cards  =  36 ways

Number of ways 4 cards can be chosen from 52 cards = 52C4 = 270725 ways

So,

Probability = 36 ways / 270725 ways

Probability = 0.0001329

Probability = 0.000133 (Approximately)

Therefore the probability is 0.000133.

Answers

The short line on the sides of the triangle tells us that those sides are equal.

We can see that LN = NJ and

LO = KO

This means that triangle LNO is similar to triangle triangle LJK

LO/NO = (LO + OK)/JK

Given that NO = 16 and JK = 6x + 8, it means that

LO/16 = (LO + OK)/(6x + 8)

Since LO = OK, it means that

LO + OK = LO + LO = 2LO

Therefore

LO/16 = 2LO/(6x + 8)By cross multiplying, it becomes

LO(6x + 8) = 2LO * 16

LO(6x + 8) = 32LO

Dividing both sides of the equation by LO, it becomes

6x + 8 = 32

6x = 32 - 8

6x = 24

x = 24/6

x = 4

The average distance between every data point is measured.Yet if the data is being treated as a population unto itself or as a sample of a broader population will affect the standard deviation calculation formula.We divide by the N number of data points if the data is being seen as a population on its own.If the data come from a sample of a larger population, then divide by n-1n1n, or n minus 1, which is one less than that of the number of points in the sample.
