[tex] \frac{ {7x}^{2} - 5x + 1}{4x + 1} [/tex]
Step-by-step explanation:
Since the denominators are the same we just have to combine the top.
[tex] {x}^{2} - 5x + {6x}^{2} + 1[/tex]
Combine alike terms.
[tex] {7x}^{2} - 5x + 1[/tex]
put that over our denominator.

In a recent survey of 79 heads of household, 46 said they did online banking on their cell phones. Find the standard error for the sample proportion of heads of household who do online banking on their cell phones. Enter your answer as a decimal rounded to three decimal places.
Answer:
[tex]SE_p = 0.055[/tex]
Step-by-step explanation:
Given
[tex]n = 79[/tex] --- Heads
Proportion, p = 46 out of 79
Required
Determine the standard error for sample proportion (SEp)
This is calculated using the following formula
[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]
In this case:
[tex]p = \frac{46}{79}[/tex]
[tex]p = 0.5823[/tex]
Substitute values for p and n in:
[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]
[tex]SE_p = \sqrt{\frac{0.5823 * (1-0.5823)}{79}}[/tex]
[tex]SE_p = \sqrt{\frac{0.5823 * 0.4177}{79}}[/tex]
[tex]SE_p = \sqrt{\frac{0.24322671}{79}}[/tex]
[tex]SE_p = \sqrt{0.00307881911}[/tex]

In a survey of 2300 people who owned a certain type of car, 460 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
20%
Step-by-step explanation
let's assume 100% = 2300
x% = 460
100% / x% = 2300/460
460x100/2300 = 20
the answer is 20%
Answer:
The survey shows that 20% of the individuals were satisfied with the car.
Step-by-step explanation:
We are given that 2,300 people were surveyed.We are also given that 460 of those individuals would buy that car again.We need to find the percentage of individuals that were satisfied with the car.When we need to find the percentage of a population, we can use the following formula:
[tex]\displaystyle \frac{\text{part}}{\text{whole}} \times 100[/tex]We need to identify the part and the whole in this problem.
We are given that 2,300 people are surveyed, so this is the whole portion.
We are also given that 460 were satisfied, so this is the part portion.
Therefore, we can set up our fraction.
[tex]\displaystyle \frac{460}{2300}[/tex]Now, let's solve the percentage.
[tex]\displaystyle \frac{460}{2300} \times 100\\\\\frac{2}{100} \times 100 = 20\%[/tex]
Therefore, of those surveyed, 20% of the individuals were satisfied with the car.

Answer:
It would be -13
Step-by-step explanation:
Answer:
-13
Step-by-step explanation:
You need to separate the 8 from each side of the equation. Picture it like this:
-104= 8 (multiplied by) x
To separate 8 from the variable, you need to divide that side by 8. Similarly, you need to do the same thing to the other side.
-104/8=8x/8
-13=x

Find the product of 11/12 (-2.4)
Answer:
-1.961666666666
Step-by-step explanation:
The highest level of PEMDAS here is multiplication/division which is done left to right. So do 11/12 first.
11/12 (-2.4)
.916 (-2.4)
Then multiply to get an answer of -1.961666666 ( the six repeats forever)
write an equation that reflects this relationship using X to represent the amount of grams in fish and y to represent the number of calories
Answer:
[tex] y = \frac{3}{2}x [/tex]
Step-by-step explanation:
The graph shows there is a proportional relationship between amount of grams of fish (x) and number of calories (y).
A original relationship can be represented by An equation as [tex] y = kx [/tex], where, k = constant of proportionality (y/x).
The constant of proportionality using any point, let's say (200, 300), would be:
k = y/x = 300/200 = ³/2
Plug in the value of k into [tex] y = kx [/tex].
Thus, the equation that reflects the relationship would be:
[tex] y = \frac{3}{2}x [/tex]
The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x) and this can be determined by using the point-slope form of a line.
Given :
A graph where the x-axis represents the number of fish in grams and the y-axis represents the number of calories.Points - (100,150) and (200,300)The point-slope form can be used to determine the equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories.
The point-slope form is given by the equation:
[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex] ----- (1)
where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.
Now, put the values of [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the equation (1).
[tex]\dfrac{y-150}{x-100}=\dfrac{300-150}{200-100}[/tex]
[tex]2(y-150)=3(x-100)[/tex]
2y - 300 = 3x - 300
2y - 3x = 0
2y = 3x
The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x).

Stefan sells Jin a bicycle for $116 and a helmet for $16. The total cost for Jin is 110% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
Answer:
He originally spent 120$
He made 12 extra dollars.
Step-by-step explanation:
To solve this I turned the 110% into a decimal.
So I divided 110 by 100 and got 1.1
In order to find the original number you would then need to divide the total cost of the bicycle and helmet together by 1.1
So, 116 + 16 = 132
132/1.1= 120

Jennifer wants to buy a new television set that regularly sells for $900. Because she works at the store, Jennifer will receive an employee discount of 30% off the regular price, but she will have to pay 6% sales tax on the adjusted price. What will be Jennifer's final cost to buy the television?
Answer:
$667.80
Step-by-step explanation:
30% of 900 is 270, so the price of the TV would be 630 without the tax. 6% of 630 is 37.8, so in total, the price would be $667.80
