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

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

Answer: A = 470 in²

Step-by-step explanation:

          If the given prism is a rectangular prism, we can use the given formula to solve for the surface area of a rectangular prism.

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

A = 2(120 in² + 75 in² + 40 in²)

A = 2(235 in²)

A = 470 in²

Answer:

h = 5t²+ 25t

from projectiles

h = u²sin²∆ / 2g

taking the angle to be ∆

and range is u²sin2∆/g

Therefore integrate the equation h= 5t²+25t

R = 5t³/3 + 25t²/2 + t

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.

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.

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

x = 59

To find the total cost of the snow thrower on the installment plan, we will first calculate the down payment and then add the total monthly payments. Here's the step-by-step explanation:
1. Calculate the down payment:
Down payment = 20% of the original price
Down payment = 0.20 * $1,248
Down payment = $249.60
2. Calculate the total of the 12 monthly payments:
Total monthly payments = 12 * $116
Total monthly payments = $1,392
3. Calculate the total cost on the installment plan:
Total cost = Down payment + Total monthly payments
Total cost = $249.60 + $1,392
Total cost = $1,641.60

This is an exercise in parametric equations, which are a way of representing a curve or surface on the plane or in space using arbitrary values or a constant called a parameter instead of using an independent variable. In the case of circles, the points (x,y) can be expressed from a single variable θ, which is called a parameter. The parametric equations of a circle with radius r ≥ 0 and center (h,k) are given by x = h + rcosθ y = k + rsinθ, where 0 < θ < 2π. The parametric equation of a circle can be expressed from the angle θ of the point through the circle with respect to the x-coordinate axis. The parametric equations of the conics, including the circumference, can be deparameterized to obtain the canonical equation.

The parametric equation of a circle can be expressed from the angle θ of the point through the circle with respect to the x-coordinate axis. The angle can be expressed in radians (θ∈[0,2π]) or sexagesimal degrees (θ∈[0º,360º]). The parametric equation of a circle with center C=(-1,3) and radius r=2 cm is defined by x = -1 + 2cosθ and y = 3 + 2sinθ.

The parametric equations of a curve are expressed from the variable (or parameter) t, such that x = x(t) and y = y(t). Each value of t determines a point (x,y) in the plane. The parametric equations of a circle with radius r ≥ 0 and center (h,k) are given by x = h + rcosθ y = k + rsinθ, where 0 < θ < 2π. The parametric equation of a circle centered at the origin and with radius r is x² + y² = r².

The parametric equations for a curve are not unique. They represent the same circle with center at (0,0) and radius R. The parametric equations of the conics, including the circumference, can be deparameterized to obtain the canonical equation. To go from the parametric to the Cartesian equations, the parameter t must be eliminated. The parametric equations of a point on a circle of radius r at an angle θ are x = rcos(θ) and y = rsin(θ).

cos²(t) + sin²(t) = 1

Multiplying both sides by 25, we get:

25 cos²(t) + 25 sin²(t) = 25

Which is equivalent to:

x² + y² = 25

Therefore, we can write:

x(t) = 5 cos(t), y(t) = 5 sin(t)

This means that for every value of t in the interval 0≤t≤2π, we can get a point on the circle.

Helping in the name of Jesus.

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.

The surface area of the rectangular pyramid is approximately 387.6 square yards.

To find the surface area of a rectangular pyramid, we need to find the area of the base and the area of the four triangular faces.

The area of the base is:

Area of base = length x width

Area of base = 14 yards x 14 yards

Area of base = 196 square yards

To find the area of the four triangular faces, we need to first find the height of each triangle using the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs (the two shorter sides) is equal to the square of the hypotenuse (the longest side).

In this case, the hypotenuse is the slant height of the pyramid, which is 12 yards. The legs are half the length and width of the base, which are both 7 yards.

So we have:

h² + 7² = 12²

h² + 49 = 144

h² = 95

h = √95

Now we can find the area of each triangular face using the formula:

Area of triangle = 1/2 x base x height

The base of each triangle is 14 yards, and the height is √95 yards. So we have:

Area of triangle = 1/2 x 14 yards x √95 yards

Area of triangle = 7√95 square yards

There are four triangular faces, so the total area of the four triangular faces is:

Total area of triangular faces = 4 x 7√95 square yards

Total area of triangular faces = 28√95 square yards

Finally, we can find the total surface area by adding the area of the base and the area of the four triangular faces:

Total surface area = Area of base + Total area of triangular faces

Total surface area = 196 square yards + 28√95 square yards

Total surface area ≈ 387.6 square yards (rounded to one decimal place)
