Step-by-step explanation:

because variable is independent

Answer: 2.

Step-by-step explanation: Don't reject H0, we can't conclude cause of the sales and the aftermath.

We can extrapolate the survey, of sample size n=20, results to the population (180 students).

To do that we have to multiply the frequency of the survey by 180/20=9.

Then, we can expect:

11 * 9 = 99 will select Cajun pasta.

4 * 9 = 36 will select chicken pasta.

5 * 9 = 45 will select shrimp pasta.

Then, we can evaluate each option:

1. There are 22 students who want chicken pasta than shrimp pasta:

There are 36 students that prefer chicken pasta rather than the other options, so this is not correct.

2. There are 60 students who want either chicken pasta or shrimp pasta.

There are 36+45=81 students who want either chicken pasta or shrimp pasta, so this is not correct.

3. There are 36 students who want Cajun pasta.

The area of triangle EFG is given as follows:

A = 18.63 square units.

The area of a rectangle of base b and height h is given by half the multiplication of dimensions, according to the formula presented as follows:

A = 0.5bh

The base is given by segment EF as follows:

\(EF = \sqrt{(9 - 4)^2 + (-7 -(-9))^2}\)

EF = 5.4.

The midpoint of EF is given as follows:

M(6.5, -8).

The height is given by the segment MG as follows:

\(MG = \sqrt{(6.5 - 3)^2 + (-2 - (-8))^2}\)

MG = 6.9.

Hence the area is given as follows:

A = 0.5bh

A = 0.5 x 5.4 x 6.9

A = 18.63 square units.

f(8) = 2(8) + 7 = 16 + 7 = 23

Answer:

5x + 6y = 20_____(1)

8x - 6y = -46_____(2)

Solving simultaneously:

Eqn(1) + Eqn(2)

5x + 8x + 6y + (-6y) = 20 + (-46)

13x = -26

x = -2

substituting this into Eqn (1):

5(-2) + 6y = 20

-10 + 6y = 20

6y = 30

y = 5

hence:

x = -2,y = 5.

Answer:

9x + 1 = 12x - 20

9x + 1 - 1 = 12x - 20 - 1

9x = 12x - 21

9x - 12x = 12x - 12x -21

-3x = -21

-3x/3 = -21/-3

x = 7

Step-by-step explanation:

Represent Burger with B and Fries with F

\(2B + F = 5.10\)

\(B + 2F = 4.80\)

Required

Determine the values of B + F

Make F the subject, in (1)

\(F = 5.10 - 2B\)

Substitute this in (2)

\(B + 2(5.10 - 2B) = 4.80\)

\(B + 10.20 - 4B = 4.80\)

Collect Like Terms

\(B - 4B = 4.80 - 10.20\)

\(- 3B = -5.40\)

Divide both sides by -3

\(B = \$1.80\)

Recall that \(F = 5.10 - 2B\)

\(F = 5.10 - 2 * 1.80\)

\(F = 5.10 - 3.60\)

\(F = \$1.50\)

One burger and One Fries = F + B

\(F +B = \$1.50 + \$1.80\)

\(F +B = \$3.30\)

Step-by-step explanation:

To find:-

Answer:-

We are interested in finding out the equation of the given circle. For that , take any two diametrically opposite coordinates. Two such coordinates are (-6,1) and (-6,9) . Now using midpoint formula , find the midpoint as ,

Midpoint formula:-

\(\longrightarrow \boxed{(x_m,y_m)=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}\\\)

On substituting the respective values, we have;

\(\longrightarrow (x_m,y_m) =\bigg(\dfrac{-6-6}{2},\dfrac{1+9}{2}\bigg) \\\)

\(\longrightarrow (x_m,y_m) =\bigg(\dfrac{-12}{2},\dfrac{10}{2}\bigg) \\\)

\(\longrightarrow \red{ (x_m,y_m) = (-6,5)}\\\)

This is the coordinate of the centre of the circle as centre is at the midpoint of the diameter. Now using distance formula , we can find the radius. Here we will use the coordinates of the centre and any one of the point on the circle say (-6,1) .

Distance formula :-

\(\longrightarrow \boxed{d =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}} \\\)

On substituting the respective values, we have;

\(\longrightarrow d =\sqrt{ \{-6-(-6)\}^2+(5-1)^2}\\\)

\(\longrightarrow d =\sqrt{ (-6+6)^2+4^2} \\\)

\(\longrightarrow d =\sqrt{0+4^2} \\\)

\(\longrightarrow d =\sqrt{4^2} \\\)

\(\longrightarrow \red{ d = 4 \ units } \\\)

Hence the radius of the circle is 4 units.

Now we know the standard equation of circle , which is ,

\(\longrightarrow (x-h)^2+(y-k)^2=r^2 \\\)

where ,

On substituting the respective values, we have;

\(\longrightarrow \{ x-(-6)^2\}^2+(y-5)^2 = 4^2 \\\)

\(\longrightarrow \underline{\underline{ \red{ (x+6)^2+(y-5)^2 = 4^2}}}\\\)

This is the required equation of the circle.

Answer:

The correct equation is A. y = (2/3)x - 2

Step-by-step explanation:

what is the formula for the whole surface area of a sphere ?

\(a = 4 \times \pi \times {r}^{2} \)

that would give us the whole surface area all 360 degrees or 2×pi arc length all around the sphere.

but we don't need all 360 degrees. we only need the Theta'th (that is the specified angle) part.

in radians the arc length of that angle segment on the "equator" of the sphere

s = r×Theta

and the whole equator circumference is

c = 2×pi×r

so, the Theta'th part is then

r×Theta / 2×pi×r = Theta / 2×pi

we only need that part of the whole sphere surface area, so the formula would look like

\(lune = theta \times 4 \times \pi \times {r}^{2} \div (2 \times \pi)\)

=>

\(lune = theta \times 2 \times {r}^{2} \)

Answer:

We can use the formula for the present value of an annuity:

PV = PMT x [(1 - (1 + r)^(-n)) / r]

where PV is the present value, PMT is the monthly payment, r is the monthly interest rate, and n is the number of payments.

Substituting the given values, we have:

PV = $31.48 x [(1 - (1 + 0.152/12)^(-18)) / (0.152/12)]

PV = $31.48 x [(1 - 0.5159) / 0.0127]

PV = $1,007.97

Therefore, the equivalent cash price of the iPod is $1,007.97.

Step-by-step explanation:

Answer: a deposit of $979.56 must be made now to have a balance of $1500 after 8 years with continuous compounding at 4.75% annual interest.

Step-by-step explanation: We can use the formula for continuous compounding:

A = Pe^(rt)

where A is the ending balance, P is the principal (initial deposit), e is the constant 2.71828..., r is the annual interest rate (as a decimal), and t is the time in years.

In this case, we know that A = $1500, r = 0.0475 (4.75% as a decimal), and t = 8 years. We want to solve for P.

P = A/e^(rt)

P = $1500/e^(0.0475*8)

P = $979.56 (rounded to the nearest cent)

Therefore, a deposit of $979.56 must be made now to have a balance of $1500 after 8 years with continuous compounding at 4.75% annual interest.

Option A. The only graph that could represent the function with the zeros of -2 and 4 is the graph is : A parabola declines from (negative 3 point 1, 10) through (negative 3, 8), (negative 2, 0), (negative 1, negative 4), (1, negative) and rises through (2, negative 8), (3, negative 4), (4, 0), (5, negative 6), and (5 point 5, 10).

The zeros of a quadratic function are the x-values where the function equals zero (where it crosses the x-axis). In this case, you mentioned that the zeros of the function are -2 and 4.

Looking at the provided options:

A. This graph crosses the x-axis at (-2, 0) and (4, 0), which are indeed the zeros of the function. Therefore, this could be a possible representation of the function.

B. This graph crosses the x-axis at (-4, 0) and (2, 0). These are not the zeros given for the function (-2 and 4), so this graph is not a possible representation of the function.

C. This graph crosses the x-axis at (-4, 0), but it never crosses at x=4. Instead, it crosses at x=2. Therefore, this is not a possible representation of the function.

D. This graph crosses the x-axis at (2, 0), but does not cross the x-axis at x=-2. Therefore, this is not a possible representation of the function.

So, the only graph that could represent the function with the zeros of -2 and 4 is the graph provided in Option A.

The probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Since the probability density function is uniform, the probability of the friend being between 10 and 30 minutes late is equal to the area of the rectangle that lies between x = 10 and x = 30, and below the curve of the probability density function.

The height of the rectangle is equal to the maximum value of the probability density function, which is 1/30 since the interval of possible values for x is [0, 30] minutes.

The width of the rectangle is equal to the difference between the upper and lower limits of the interval, which is 30 - 10 = 20 minutes.

Therefore, the probability of the friend being between 10 and 30 minutes late is:

P(10 < x < 30) = (height of rectangle) x (width of rectangle)

= (1/30) x 20

= 2/3

≈ 0.6667

So the probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

The equation of the line is x = -7. The equation of the other line is x = -3 and the equation in intercept form is x/-3 = 1

It is given that the x-intercept is at -7. this implies that the line passes through the point (-7,0)

The formula of the slope of the lines is (y₂ - y₁)/(x₂ - x₁) where (x₁ , y₁) and (x₂,y₂) are 2 points the line passes through.

Since the slope of the line is undefined, x₂ - x₁ = 0

This implies that the line is parallel to the y-axis

Hence, the equation of the line is

x = -7.

Here we see that the x-intercept and any other point have the x coordinate of -3.

Hence the equation of the line will be x = -3

The equation of this particular line in slope intercept form is

The loss on selling 50 shares of stock would be 87.50.

To calculate the loss on selling 50 shares of stock originally bought at

\(13\frac{3}{4}\) and sold at 12, we need to determine the difference between the purchase price and the selling price, and then multiply it by the number of shares sold.

First, let's convert the purchase price from a mixed fraction to a decimal. \(13\frac{3}{4}\) can be expressed as 13.75.

Next, we calculate the difference between the purchase price and the selling price:

\(13.75 - 12 = 1.75.\)

Finally, we multiply the difference by the number of shares sold:

\(1.75 \times50 = 87.50.\)

Therefore, the loss on selling 50 shares of stock would be 87.50.
