Ximena gave out a survey to some students in her school about their favorite color. students could choose between red and blue. 180 of those surveyed said their favorite color was red. 55% of the students surveyed said their favorite color was blue. how many students were surveyed in total?

Answers

Answer 1

Answer:

Step-by-step explanation:

what we know is that 45% of the total was 180 (they voted red)

55% of the total voted blue.

To find the total, we need to set up a cross-multiplication equation

180/45 = ?/100

180 times 100 is 18000

18000/45 = 400

400 students were surveyed in total

we can check this by getting 55% of this, and adding it to 180.

If it equals to 400, then we're right.

55% of 400 = 220

220 + 180 = 400

The credit card industry works similar to the cigarette industry. what reasons caused culture to change its view of cigarettes over the past few decades? what do you think would need to happen to change america's view of credit cards?

Answers

The credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.

What is credit card?

A credit card is a sort of payment card that uses a line of credit rather than the account holder's cash deposits to make purchases.

Tobacco use can have a negative impact on personal finances due to the sheer high price of tobacco products, wasted pay owing to sickness absence, plus hospitalization rates due to the higher risk of illness associated with smoking use.

If you let that debt grow, you may find that the amount of interest you owe equals or even exceeds your original principal, forcing you to spend a lot just to pay it off.

Thus, the credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.

3. The value of a car in relation to the number of miles driven is given by the linear
function y = -9x + 55000.
a. Interpret the meaning of the rate of change and initial value for the linear function.

Answers

Answer:

General form of a linear equation:  [tex]y=mx+b[/tex]

(where m is the slope and b is the y-intercept)

A linear equation has a constant rate of change which is represented by the slope (m).  It is the rate at which one quantity is changing with respect to another quantity.

Question 3

Part (a)

Given equation:  [tex]y=-9x+55000[/tex]

where:

y = value of car (in dollars)x = number of miles driven

The rate of change (slope) is -9 and represents that for every 1 mile driven, the value of the car decreases by $9.

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial value of car is $55,000.

Part (b)

To find the number of miles at which the car be valued at $35,002, set the equation to $35,002 and solve for x:

[tex]\implies -9x+55000=35002[/tex]

[tex]\implies -9x=35002-55000[/tex]

[tex]\implies -9x=-19998[/tex]

[tex]\implies x=\dfrac{-19998}{-9}[/tex]

[tex]\implies x=2222[/tex]

Therefore, the car will be valued at $35,002 after 2,222 miles.

Question 4

Given equation:  [tex]y=0.39x+2.55[/tex]

where:

y = price of carrots (in dollars)x = weight (in oz)

The rate of change (slope) is 0.39 and represents that for every increase of 1 oz of weight in carrots, the price of the carrots increases by $0.39

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial cost of the carrots is $2.55.

Part (b)

To find the weight of carrots you can buy for $6.06, set the equation to $6.06 and solve for x:

[tex]\implies 0.39x+2.55=6.06[/tex]

[tex]\implies 0.39x=6.06-2.55[/tex]

[tex]\implies 0.39x=3.51[/tex]

[tex]\implies x=\dfrac{3.51}{0.39}[/tex]

[tex]\implies x=9[/tex]

Therefore, you can buy 9 oz of carrots for $6.06

Part (c)

To find out how much it costs to buy 21 oz of carrots, substitute x = 21 into the equation and solve for y:

[tex]\implies y=0.39(21)+2.55[/tex]

[tex]\implies y=10.74[/tex]

Therefore, it costs $10.74 to buy 21 oz of carrots.

Answers

An equation is formed of two equal expressions. Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A.) Let the amount of time spent on soccer be represented by y, while the amount of time spent on softball is represented by x. Therefore, we can write,

x+y=18

y=2x+1.5

Hence, the system of equations to model the situation is x+y=18 and y=2x+1.5.

B.) Substitute the value of y from the second equation in the first equation, therefore,

x+y=18

x+2x+1.5=18

3x = 16.5

x = 5.5 hours

Substitute the value of x in the second equation, we will get,

y=2x+1.5

y=2(5.5)+1.5

y=11+1.5

y=12.5 hours

Hence, Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

Answer:

2/13

Step-by-step explanation:

4/14 × 7/13  when i simplify it becomes 2/13!!!

The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.

What is Probability?

Probability helps us to know the chances of an event occurring. The sum of all the probabilities of an event is always equal to 1. The formula for probability is given as,

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The probability of getting a blue marble at the first try is,

Probability(Blue) = Number of blue marbles / Total number of marbles

                            = 4 / 14

The probability of getting a red marble at the second try is,

Probability(Red) = Number of Red marbles / Total number of marbles

                            = 7 / 13

The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is,

Probability = Probability(Blue) × Probability(Red)

                   = (4/14) × (7/13)

                   = 2/13

Hence, the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here a = 2 and (h, k ) = (6, 4 ) , then

y = 2(x - 6)² + 4 ← in vertex form

expand factor using FOIL

y = 2(x² - 12x + 36) + 4 ← distribute parenthesis by 2

Avery bought stock in a company two years ago that was worth x dollars. During the first year that she owned the stock, it increased by 40%. During the second year the value of the stock decreased by 10%.

Answers

Answer:

The value of the stock can be found by: x × 1.26.

Step-by-step explanation:

The value of the stock in year one can be found by multiplying x by 1.4. This will represent a 40% increase in value. The following year, the stock decreases in value by 10%; this is represented by multiplication by 0.9. For example, if the value of the stock was $5:

5 × 1.4 = 7                    (A 40% increase in value)

(5 × 1.4) * 0.90 = 6.3   (A further 10% decrease in value)

Rather than writing out the long version, we can simplfify by multiplying 1.4 by 0.9 to get 1.26 .We can also replace 5 with x to get a more general equation.
