The diameter of the larger pie is 8 x sqrt(2) inches.

The area of a circle is proportional to the square of its diameter. If the diameter of a pie made with one can of pumpkin pie mix is 8 inches, then its area is (4 inches)^2 x pi = 16 pi square inches.

If two cans of pie mix are used to make a larger pie of the same thickness, the total area of the pie will be twice that of the smaller pie.

So, the area of the larger pie is 2 x 16 pi = 32 pi square inches.

To find the diameter of the larger pie, we need to solve for d in the equation:

Area of circle = (d/2)^2 x pi

32 pi = (d/2)^2 x pi

32 = (d/2)^2

Taking the square root of both sides, we get:

sqrt(32) = d/2 x sqrt(2)

d/2 = sqrt(32)/sqrt(2)

d/2 = 4 x sqrt(2)

d = 8 x sqrt(2)

Therefore, the diameter of the larger pie is 8 x sqrt(2) inches.

Barry will charge $24.50 for 7 baseball cards if he keeps selling cards at the same rate.

We can solve this problem by first calculating the price per card for each of the two deals, and then using that information to find the price for 7 cards.

Let x be the price of one baseball card, in dollars. From the information given, we know that:

2 cards cost $8.00, so 1 card costs $4.00: 2x = 8.00 => x = 4.00

4 cards cost $14.00, so 1 card costs $3.50: 4x = 14.00 => x = 3.50

So we see that the price per card is different for the two deals. To find the price for 7 cards, we can use a weighted average of the two prices:

Price for 2 cards: $8.00

Price for 4 cards: $14.00

Total price for 6 cards: $22.00

We can now find the price for one more card by subtracting the total price for 6 cards from the price for 7 cards:

Price for 7 cards: $?

Price for 6 cards: $22.00

Price for 1 card: $?

Price for 7 cards = Price for 6 cards + Price for 1 card

Price for 1 card = Price for 7 cards - Price for 6 cards

We know that the total price for 7 cards is the same as the price for 2 cards plus the price for 4 cards plus the price for 1 more card:

Price for 7 cards = Price for 2 cards + Price for 4 cards + Price for 1 card

Price for 7 cards = 2x + 4x + 1x = 7x

Substituting the value we found for x earlier, we get:

Price for 1 card: $3.50

Price for 7 cards: $24.50

Therefore, Barry will charge $24.50 for 7 baseball cards if he keeps selling cards at the same rate.

The correct inequality to describe the problem is A. 10 + x > 15, which means that the total time Farid spends on the level (10 + x) must be greater than 15 minutes in order for him to lose a life.

To solve the inequality, we can start by isolating x on one side of the inequality:

10 + x > 15

Subtracting 10 from both sides, we get:

x > 5

This means that Farid can play for up to 5 more minutes on the level without losing a life, since spending a total of 10 + 5 = 15 minutes on the level would cause him to lose a life.

Therefore, the solution to the inequality is "Farid can play less than 5 more minutes on that level without losing a life."

To build a house in 96 days, more workers are required such that the total number of workers becomes 24.

Let W be the number of workers required to build the house in 96 days. Using the work formula, we can write:

(16 workers) x (144 days) = (W workers) x (96 days)

Simplifying the equation, we get:

W = (16 workers x 144 days) / 96 days = 24 workers

Therefore, to build the house in 96 days, 24 workers are required, which is 8 more workers than the original 16. This is because, to complete the work in a shorter time, more workers are needed to contribute their efforts to the work.

we can say with 99% confidence that the true proportion of times the number cube would land with a six facing up is between 0.05 and 0.49.

To find the 99% confidence interval for the true proportion of times the number cube would land with a six facing up, we can use the formula:

CI = p ± zsqrt(p(1-p)/n)

where:

CI is the confidence interval

p is the sample proportion (number of times the cube landed with a six facing up divided by the total number of rolls)

z is the z-score corresponding to the desired confidence level (99% in this case)

n is the sample size (45 in this case)

First, let's calculate the sample proportion:

p = 12/45 = 0.27

Next, we need to find the z-score corresponding to a 99% confidence level. Using a standard normal distribution table or calculator, we find that the z-score is 2.58.

Now we can plug in the values and calculate the confidence interval:

CI = 0.27 ± 2.58sqrt(0.27(1-0.27)/45)

CI = 0.27 ± 0.22

CI = (0.05, 0.49)

A. proj_v(u) = (586 / 68) * (8i + 2j) = (293 / 34) * (8i + 2j) ≈ 8.62i + 2.15j

B. u_orthogonal = (71 + 9j) - (8.62i + 2.15j) ≈ 62.38i + 6.85j

(a) To find the projection of vector u onto vector v, we use the formula:

proj_v(u) = (u·v / ||v||^2) * v

where u = 71 + 9j, v = 8i + 2j, "·" represents the dot product, and ||v|| represents the magnitude of v.

First, let's find the dot product u·v:

u·v = (71)(8) + (9)(2) = 568 + 18 = 586

Next, we find the magnitude of v:

||v|| = √((8)^2 + (2)^2) = √(64 + 4) = √68

Now, we find ||v||^2:

||v||^2 = 68

Finally, we can find the projection of u onto v:

proj_v(u) = (586 / 68) * (8i + 2j) = (293 / 34) * (8i + 2j) ≈ 8.62i + 2.15j

(b) To find the vector component of u orthogonal to v, we subtract the projection of u onto v from u:

u_orthogonal = u - proj_v(u)

u_orthogonal = (71 + 9j) - (8.62i + 2.15j) ≈ 62.38i + 6.85j

Step-by-step explanation:

y = mx + b to write the equation, we need 2 things: the slope and the y-intercept

y = ___x + ____

Slope:

Change in y over the change in x.  We find the change by subtracting.   The y values are 6 and -2.  The x values are -4 and -8

[tex]\frac{6- (-2)}{-4 -(-8)}[/tex] = [tex]\frac{6+2}{-4+8}[/tex] = [tex]\frac{8}4}[/tex] = 2

The slope is 2.

y-intercept:

Use either of the points given and the slope 2 to find the y-intercept.  I am going to use the points(-4,6).  I will use -4 for x and 6 for y given from the point

y = mx + b

6 = 2(-4) + b

6 = -8 + b  Add 8 to both sides

14 = b

The y-intercept is 14.

The probability that a seal properly fits a valve is approximately 0.9332 or 93.32%.

To determine the probability that a seal properly fits a valve, we need to calculate the probability that the difference in diameter between the seal and valve is less than or equal to 2 mm.

Let X be the diameter of the valve and Y be the diameter of the seal. Then, the difference in diameter between the seal and valve can be expressed as Z = Y - X. We want to find P(Z ≤ 2).

We know that X ~ N(50, 0.3²) and Y ~ N(51, 0.4²), and since Z = Y - X, we have:

Z ~ N(51 - 50,  √(0.3² + 0.4²)²) = N(1, 0.5²)

To find P(Z ≤ 2), we standardize Z by subtracting the mean and dividing by the standard deviation:

(Z - 1)/0.5 ~ N(0, 1)

P(Z ≤ 2) = P((Z - 1)/0.5 ≤ (2 - 1)/0.5) = P(Z ≤ 1.5)

Using a standard normal table or calculator, we find that P(Z ≤ 1.5) ≈ 0.9332.

Therefore, the probability that a seal properly fits a valve is approximately 0.9332 or 93.32%.

The mathematical model that pattern using an equation to represents  the height is h, the leaf scar is l is given by x = c × l × √n × cos(n × φ) , and y = c × l × √n × sin(n × φ) + h.

The pattern of leaf scars on a tree trunk is often modeled using a mathematical function called a phyllotaxis spiral.

This spiral can be represented by the polar equation,

r = c × √n

where r is the radius of the spiral,

n is the index of the leaf scar,

c is a constant that determines the tightness of the spiral,

and the angle of rotation is equal to,

θ = n × φ

where φ is the golden angle, which is approximately 137.5°.

To incorporate the height h and leaf scar size l into the model,

Make the following modifications,

Add a vertical displacement factor h to the polar equation, which shifts the spiral upward by h units.

Multiply the radius by a factor that is proportional to the size of the leaf scar l.

The modified polar equation for the phyllotaxis spiral would be,

r = c × l × √n

θ = n × φ

where r is the radius of the spiral,

n is the index of the leaf scar,

c is a constant that determines the tightness of the spiral,

l is the size of the leaf scar,

and φ is the golden angle.

To convert this polar equation to a Cartesian equation that relates x and y coordinates,

x = r × cos(θ)

y = r × sin(θ) + h

Substituting the expressions for r and θ from above, we get,

x = c × l × √n × cos(n × φ)

y = c × l × √n × sin(n × φ) + h

Therefore, mathematical equation that models the phyllotaxis spiral of leaf scars on a tree trunk, taking into account the height h and the size of the leaf scar l is

x = c × l × √n × cos(n × φ)

y = c × l × √n × sin(n × φ) + h

it's not possible to sell at least $675 worth of tickets while also staying within the seating limit of 150 tickets. The theater may need to consider raising ticket prices or finding a larger venue to accommodate more audience members.

Let's denote the number of adult tickets sold as "A" and the number of child tickets sold as "C". Then we can set up the following system of equations to represent the given information:

A + C ≤ 150    (limit on seating)

12A + 7.5C ≥ 675   (minimum revenue required)

We want to find the possible values of A and C that satisfy these equations.

One way to solve this system is to graph the inequalities and find the region of overlap. However, since there are only two variables, we can also use substitution or elimination to solve for one variable in terms of the other.

Let's solve for A in terms of C using the first equation:

A ≤ 150 - C

Substitute this expression for A in the second equation:

12(150 - C) + 7.5C ≥ 675

Expand and simplify:

1800 - 12C + 7.5C ≥ 675

-4.5C ≥ -1125

C ≤ 250

So the number of child tickets sold must be less than or equal to 250.

Now we can substitute this inequality into the first equation to find the maximum number of adult tickets sold:

A + 250 ≤ 150

A ≤ -100

This doesn't make sense, since we can't sell negative tickets. Therefore, there is no solution that satisfies the given conditions.
