Enola gave out a survey to some students in her school about their favorite color. Students could choose between blue and purple. 371 of those surveyed said their favorite color was blue. 47% of the students surveyed said their favorite color was purple. How many students were surveyed in total?

Answer:

cant really solve for it i think

Step-by-step explanation:

to find the slope use the equation

y 2 y- 1 / x2 - x1

300 - 180 / 3 - 5

120 / -2

-60

y = -60x + b

now to find the y-intercept you need another point so umm... you may need to ask your teacher

Answer:

The first study was an observational study whereas the second was a controlled experiment.

I just took the test and it was right.

The first study was an observational study whereas the second was a controlled experiment.

Study is the devotion of time and attention to gaining knowledge of an academic subject, especially by means of books.

Here, given that,

In one study on the effect of coconut oil on hair growth, 140 subjects who acknowledged being long-time coconut oil users had their hair growth compared with those of 140 people who had never used coconut oil.

In a second study, 80 subjects were randomly chosen to use coconut oil and 80 were chosen to use a placebo.

Hence, The first study was an observational study whereas the second was a controlled experiment.

Answer:

[tex]n = 304[/tex]

Step-by-step explanation:

Given

[tex]y = -15x - 6[/tex]

[tex]Points: (n,-12) \& (4,8)[/tex]

Required

Determine the value of n

First, we need to determine the slope of the given equation.

An equation is of the form;

[tex]y = m_1x + b[/tex]

Where m = slope.

By comparison.

[tex]m_1 = -15[/tex]

Since the given point and the given equation are perpendicular, then:

[tex]m = -\frac{1}{m_1}[/tex]

[tex]m = -\frac{1}{-15}[/tex]

[tex]m = \frac{1}{15}[/tex]

The slope of the point is calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (n,-12)[/tex]

[tex](x_2,y_2) = (4,8)[/tex]

[tex]m = \frac{1}{15}[/tex]

So, we have:

[tex]\frac{1}{15} = \frac{8 - (-12)}{4 - n}[/tex]

[tex]\frac{1}{15} = \frac{8 +12}{4 - n}[/tex]

[tex]\frac{1}{15} = \frac{20}{4 - n}[/tex]

Cross Multiply

[tex]4 - n = 20 * 15[/tex]

[tex]4 - n = 300[/tex]

Solve for n

[tex]n = 4 + 300[/tex]

[tex]n = 304[/tex]

Using the Fundamental Counting Theorem, it is found that the flags can be displayed in 518,400 ways.

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem, we have that odd positions get South American countries, hence:

[tex]n_1 = 6, n_3 = 5, n_4 = 3, \cdots, n_11 = 1[/tex]

Even positions get European countries, hence:

[tex]n_2 = 6, n_4 = 5, \cdots, n_12 = 1[/tex]

Hence, since the number of ways for both the South American and European countries is the factorial of 6, we have that:

N = 6! x 6! = 518,400

The flags can be displayed in 518,400 ways.

Answer:

£40

Step-by-step explanation:

If £1 = $1.35

To convert $ to £, divide $ by 1.35

⇒ $54 = 54/1.35 = £40

Division is one of the most basic arithmetical operators. The amount that Alejandro need to save for each month is $375.

The division is one of the most basic arithmetical operators. When we divide a number (P) by another number(q), then it tells us how many times the other number(q) must be added to itself to form the first number(P).

It is given that the cost of tuition for the two years is $12,000, while the financial aid that Alejandro is eligible for is $7500, therefore, the amount that he will not be able to pay with his scholarship(financial aid) will be the difference in the fees of the student and the financial aid he is getting.

Difference = Two-year tuition fees - Financial Aid

                 = $12,000 - $7,500

                  = $4,500

Now, since Alejandro needs to save for a year so the sum he saves is $4500 therefore, the amount he needs to save each month can be written as,

[tex]\text{Amount Alehjandro needs to save each moth}=\dfrac{\text{Amount that Alejandro need to save}}{\text{Number of months he needs to save}}[/tex]

[tex]\text{Amount Alehjandro needs to save each moth}=\dfrac{4500}{12} = \$375[/tex]

Hence, the amount that Alejandro need to save for each of the month so that he can pay his tuition fee is $375.

Answer:

x = 5, y = 2

Step-by-step explanation:

First, find the value of x in respect to y:

2x + 3y = 16
2x = 16 - 3y

x = 8 - 3/2y

Then, substitute this expression into the second equation (Since we've established x is equal to 8 - 3/2y, we can put that in place of x):

4(8 - 3/2y) + 10y = 40

Then, distribute and solve for y:

32 - 6y + 10y = 40
32 + 4y = 40
4y = 8
y = 2

Now that we know what y equals, we can substitute the value of y in the equation to find x:
2x + 3(2) = 16
2x + 6 = 16
2x = 10

x = 5

Step-by-step explanation:

f(x)=3log(x−7)+1

There is no y intercept

log (x) does not intercept the y axis.  This shifts the function 7 units to the right so the graph will not intercept the y axis

Answers:

His first statement is incorrect

His second statement is correct.

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

Explanation:

The first statement is incorrect because plugging x = 0 into f(x) leads to

f(x) = 3*log(x-7)+1

f(0) = 3*log(0-7)+1

f(0) = 3*log(-7)+1

We stop here because we cannot take the log of a negative number (unless you want a complex number but that's for another time). This means that x = 0 is not in the domain. The domain is x > 7 to ensure that x-7 > 0. That way we avoid taking the log of a negative number, and taking the log of zero as well.

The vertical asymptote is at x = 7 and the log curve is entirely to the right of it, so there's no way it's reaching the y axis.

Simply put: there is no y intercept for this function.

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

The second statement is correct.

The function y = log(x) has y go off to infinity when x does.

The same applies to y = 3log(x) and y = 3log(x-7) and y = 3log(x-7)+1

We can say it "rises to the right" as another way of describing part of the end behavior.

Answer:

Answer: Y = 4x - 12

Step-by-step explanation:

Well, the reason for this is because y can be anything because there are 2 unknown terms in the equation. Thus, the answer to y can be many different answers. The one common thing that all of these answers have is that they have only 1 expression (An equation without equal sign) to solve it. This expression is the answer to y, but it can be changed judging by the answer of x. That is why you cannot determine an exact answer to y with there being many, so you have to write the expression to get y. Which you can find out by:

12 (Part) + y (Part) = 4x (Whole)

So to figure out one part do the whole minus the other part which is why 4x is our answer:

4x (Whole) - 12 (Other Part)

This is called part-whole postulate.

percentage, a relative value indicating hundredth parts of any quantity.

Given that seiko deposits $3500 into an account that pts 5.8% annual interest monthly.

We need to find the balance after 8 years.

[tex]A=Pe^{rt}[/tex]

P is the principle amount which is 3500

r is rate of interest =5.8%=5.8/100=0.058

t is the time period=8 years

[tex]A=3500e^{0.058(8)}[/tex]

[tex]A=3500e^{0.464}[/tex]

A=3500(1.59)

A=5565

Hence, if Seiko deposits $3500 into an account that pts 5.8% annual interest monthly then the balance after 8 years is 5565.
