Answer:

8/27

Step-by-step explanation:

There are a total of 27 students in the class, and 8 of them are accounting majors. Therefore, the probability of the first student selected being an accounting major is 8/27.

After the first student is selected, there will be 26 students remaining, out of which 6 are art majors. Therefore, the probability of the second student selected being an art major, given that the first student was an accounting major, is 6/26.

To find the probability of both events occurring together, we need to multiply the individual probabilities:

P(accounting major first) * P(art major second | accounting major first)

= (8/27) * (6/26)

= 48/702

= 8/117

Answer:

Option A is correct: the cross-section of a sphere must be a circle.

When a sphere is cut by a plane, the resulting cross-section will always be a circle, regardless of the orientation or angle of the cut. This is because all cross-sections of a sphere have the same shape and size as a great circle, which is a circle that passes through the center of the sphere and divides it into two equal halves.

Option B is not correct because an ellipse is not a possible cross-section of a sphere.

Option C is not correct because the cross-section of a sphere can only be a circle, not an ellipse.

Option D is not correct because a line is not a possible cross-section of a sphere. A line can only be a cross-section of a cylinder or a cone, but not a sphere.

Answer:

p(large or green) = 0.794

Step-by-step explanation:

If a marble is randomly selected from the box, we need to find the

probability that it is small or green

1. Find P(large) ⇒ P(l)

2.Find P(green) ⇒ P(g)

3. Find P(large and green) ⇒ P(l and g)

4. Use the rule P(large or green) = P(l) + P(g) - P(l and g)

∵ The box contains 18 large marbles and 16 small marbles

∴ The total number of marbles = 18 + 16 = 34

∴ P(l) = 18/34

∵ There are 7 large green marbles

∵ There are 18 large marbles

∴ P(l and g) = 7/34

∴ P(g) = 16/34

∵ P(large or green) = P(l) + P(g) - P(l and g)

∴ P(large or green) = 18/34 + 16/34 - 7/34

∴ P(large or green) = 27/34

= 0.7941176471

If a marble is randomly selected from the box, then the probability that it is large or green is 0.794

Answer:

To find the area of the shaded region, we need to first find the x-coordinates of the points where the two functions intersect. We can set f(x) = g(x) and solve for x:

x^4 - 12x^3 + 48x^2 = 44x + 105

x^4 - 12x^3 + 48x^2 - 44x - 105 = 0

We can use a numerical method, such as the Newton-Raphson method, to approximate the roots of this equation. Using a graphing calculator or computer algebra system, we can find that the roots are approximately:

x = -1.932, x = 0.695, x = 4.149

Note that the root x = -1.932 is outside the given interval [3, 4], so we can ignore it.

The shaded region is bounded by the x-axis, the line y = 340, and the graphs of f(x) and g(x) between x = 3 and x = 4. To find the area of this region, we can integrate the difference between the two functions over this interval:

A = ∫3^4 [g(x) - f(x)] dx

A = ∫3^4 [44x + 105 - (x^4 - 12x^3 + 48x^2)] dx

A = ∫3^4 [-x^4 + 12x^3 - 48x^2 + 44x + 105] dx

We can integrate term by term using the power rule:

A = [-x^5/5 + 3x^4 - 16x^3 + 22x^2 + 105x]3^4

A = [-1024/5 + 192 - 192 + 22 + 105] - [-81/5 + 108 - 192 + 66 + 105]

A = 347.2

Therefore, the area of the shaded region is approximately 347.2 square units.

The chances that, at least, one of the dinosaur toys in Franklin's set is a T.rex is 57%.

We can use the complement rule to find the probability that none of the dinosaur toys in Franklin's set is a T. rex, and then subtract this from 1 to get the probability that at least one of the toys is a T. rex.

The probability that a given toy is not a T. rex is 90%, or 0.9.

Since there are 8 toys in the set, the probability that none of them are T. rex is:

0.9 x 0.9 x 0.9 x 0.9 x 0.9 x 0.9 x 0.9 x 0.9 = 0.43

So the probability that at least one of the toys is a T. rex is:

1 - 0.43 = 0.57, or 57%

In other words, it is 57% likely that at least one of the dinosaur toys in Franklin's set is a T. rex.

The value of y is 3 when x = 25.

When two variables, x, and y, vary inversely, it means that as one variable increases, the other decreases in a proportional manner. In other words, their product is constant.

Mathematically, this relationship can be expressed as:

y = k/x

where k is the constant of proportionality.

To solve the problem, we are given that y = 5 when x = 15, which can be rewritten as:

5 = k/15

To find the value of y when x = 25, we need to first determine the value of k. We can do this by rearranging the equation above to solve for k:

k = 5 x 15 = 75

Now that we know the constant of proportionality, we can use it to find the value of y when x = 25:

y = k/x = 75/25 = 3

Therefore, when x = 25, y = 3. This means that as x increases from 15 to 25, y decreases from 5 to 3, in accordance with the inverse variation relationship between x and y.

A graph that represent the system of quadratic equations is shown in the image attached below.

In Mathematics and Geometry, the graph of a quadratic function would always form a parabolic curve because it is a u-shaped. Based on the given quadratic function, we can logically deduce that the graph would be an upward parabola because the coefficient of x² is positive and the value of "a" is greater than zero (0).

By expanding the bracket, we have:

f(x) = (x - 4)(x + 4)

f(x) = x² - 4x + 4x - 16

f(x) = x² - 16

Since the leading coefficient (value of a) in the given quadratic function y = x² - 8x + 12 is positive 1, we can logically deduce that the parabola would open upward and the y-intercept is given by the ordered pair (0, 12).

The measure of the first Angle is 59 degrees, the second angle is x + 18 = 77 degrees, and the third angle is x - 15 = 44 degrees

In any triangle, the sum of the measures of the three angles is always 180 degrees.

Let x be the measure of the first angle.

The second angle is x + 18 because it is given that the second angle is 18 more than the first angle.

The third angle is x - 15 because it is given that the third angle is 15 less than the first angle.

So, we have:

x + x + 18 + x - 15 = 180

Simplifying and solving for x, we get:

3x + 3 = 180

3x = 177

The equation that relates the cost of a bouquet to the number of balloons in the bouquet is: Y = 5.75x

The bouquet with 6 balloons, and the cost per balloon is:

34.50 / 6 = 5.75

We can repeat this process for each bouquet to get:

6 balloons: cost per balloon = 5.75

9 balloons: cost per balloon = 3.83

12 balloons: cost per balloon = 3.04

we can write an equation of the form: Y = kx

where Y is the cost of a bouquet,

x is the number of balloons in the bouquet, and

k is a constant that represents the cost per balloon.

To solve for k, we can use any one of the bouquets to get:

34.50 = k(6)

The plane traveled approximately 15,806 feet from point A to point B.

tan(angle) = opposite side / adjacent side

Let x be the horizontal distance from Qasim to point A and y be the horizontal distance from Qasim to point B. Then:

tan(16°) = 7200 / x

tan(38°) = 7200 / y

We can solve for x and y:

x = 7200 / tan(16°)

y = 7200 / tan(38°)

Now, we can calculate x and y:

x ≈ 7200 / 0.2878

= 25016.6 feet

y = 7200 / 0.7813

= 9210.7 feet

Finally, to find the distance the plane traveled from point A to point B, we take the difference between y and x:

distance = y - x

= 9210.7 - 25016.6

= -15805.9 feet

A = 2((8 in)(15 in) + (5 in)(15 in) + (5 in)(8 in))

A. The initial size of the culture is 222.11

B. The doubling period is approximately 13.53 minutes.

C. The population after 100 minutes is 5807.76

D . The population will reach 13000 after approximately 44.59 minutes.

Use the formula for exponential growth:

N = N0 × eʳᵗ

where N is the population size at time t, N0 is the initial population size, r is the growth rate, and t is the time elapsed.

Using the given data:

At t=10, N=500

500 = N0 × eʳ×¹⁰

At t=30, N=1500

1500 = N0 × eʳ׳⁰

To solve for N0 and r, we can divide the second equation by the first:

¹⁵⁰⁰/₅₀₀ = eʳ׳⁰ / eʳ×¹⁰

3 = eʳ× ²⁰

Taking the natural logarithm of both sides:

ln(3) = r × 20

r = ln³/₂₀

r ≈ 0.0513 (rounded to 4 decimal places)

Now we can use N = N0 × eʳᵗ to answer the remaining questions:

- The initial size of the culture is:

N0 = N / eʳᵗ = 500 / ₑ(0.0513×10) ≈ 222.11 (rounded to 2 decimal places)

- The doubling period is the time it takes for the population to double. Find this by setting N = 2N0 and solving for t:

2N0 = N0 × eʳᵗ

2 = eʳᵗ

ln(2) = rt

t = ln²/ᵣ

t ≈ 13.53 (rounded to 2 decimal places)

So the doubling period is approximately 13.53 minutes.

- The population after 100 minutes is:

N = N0 × eʳᵗ = 222.11 × ₑ(0.0513×100) ≈ 5807.76 (rounded to 2 decimal places)

- To find when the population reaches 13000, we can solve N = 13000 for t:

13000 = N0 × eʳᵗ

13000 = 222.11 × ₑ(0.0513t)

58.56 = ₑ(0.0513t)

ln(58.56) = 0.0513t

t ≈ 44.59 (rounded to 2 decimal places)

So the population will reach 13000 after approximately 44.59 minutes.
