what is the probability of hitting a triangle on this dashboard?

Answer:

140°

Step-by-step explanation:

The exterior angle is equal to the sum of the 2 remote interior angles. (The 2 angles farthest from the angle on the outside of the triangle)

20 + 120 = 140

Answer:

y= 140

Step-by-step explanation:

first you find x by using the sum of angles in a triangle(180-120-20). so x is 40.and then you do 180-40 ( adjustment angles on a straight line. let me know if it makes sense.

Using the formula of area of a circle, about 226.08in² has been eaten

The diameter of the pizza is given as 24 inches. To calculate the area of the entire pizza, we need to use the formula for the area of a circle:

Area = π * r²

where π is approximately 3.14 and r is the radius of the circle.

Given that the diameter is 24 inches, the radius (r) would be half of the diameter, which is 12 inches.

Let's calculate the area of the entire pizza first:

Area = 3.14 * 12²

Area = 3.14 * 144

Area ≈ 452.16 square inches

Now, if half of the pizza is consumed, we need to calculate the area of half of the pizza. To do that, we divide the area of the entire pizza by 2:

Area of half of the pizza = 452.16 / 2

Area of half of the pizza ≈ 226.08 square inches

Therefore, if half of the pizza is consumed, approximately 226.08 square inches of pizza would be eaten.

The maximum area of the Norman window is given by the area of the rectangle, which is \(x * x = x^2\), approximately 85.18 square feet.

A Norman window consists of a semicircle placed on top of a rectangle, where the diameter of the semicircle is equal to the width of the rectangle. Let's assume the width of the rectangle is 'x' feet. This means the height of the rectangle is also 'x' feet, and the radius of the semicircle is 'x/2' feet.

To calculate the perimeter of the window, we add the perimeter of the rectangle and half the circumference of the semicircle. The perimeter of the rectangle is 2(x + x/2) = 3x, and half the circumference of the semicircle is π(x/2)/2 = πx/4. Adding these two values, we get the equation:

3x + πx/4 = 30

To find the maximum area, we need to maximize the width 'x'. Solving the above equation, we find x ≈ 9.23 feet.

Therefore, the maximum area of the Norman window is given by the area of the rectangle, which is \(x * x = x^2\), approximately 85.18 square feet.

Step-by-step explanation:

The differential equation is of order 2 and nonlinear. The order of a differential equation is the highest order derivative that appears in the equation. In this case, the highest order derivative is y′′(x), so the order of the differential equation is 2.

The equation is nonlinear because the term sin(y(x)) contains a product of the dependent variable y(x) and its derivative y′(x). If the equation did not contain this term, then it would be linear.

One vase of flowers contains eight purple tulips and six yellow tulips. A second vase of flowers contains five purple tulips and nine yellow tulips. An example of dependent events is selecting a purple tulip from the first vase and then selecting a yellow tulip.

The probability of selecting a purple tulip from the first vase is 8/14. Therefore, the probability of selecting a yellow tulip from the first vase is 6/14. Now, the second event is to select a tulip from the second vase. The event of choosing a purple tulip from the second vase is 5/14. Therefore, the second event would depend on the result of the first event. The answer is "yellow tulip" since the two events are dependent on each other.

The value of the double integral is \(\(\frac{40}{3}\)\) or 13.333

To evaluate the double integral of the function \(\(f(x, y) = x + 8y\)\) over the region R bounded by (x = 0), (x = 2), (y = 0), and (y = x), we can set up the integral as follows:

\(\[\iint_R f(x, y) \, dx \, dy\]\)

We integrate first with respect to x and then with respect to y, using the given bounds for each variable. The limits of integration for x are from 0 to 2, and the limits for y are from 0 to x. Therefore, we can write the integral as:

\(\[\int_0^2 \int_0^x (x + 8y) \, dy \, dx\]\)

Now, we can evaluate the inner integral with respect to y first:

\(\[\int_0^x (x + 8y) \, dy = \left[xy + 4y^2\right]_0^x\]\)

Simplifying, we have:

\(\[x^2 + 4x^2 = 5x^2\]\)

Now, we can evaluate the outer integral with respect to x :

\(\[\int_0^2 5x^2 \, dx\]\)

Integrating, we get:

\(\[\left[\frac{5}{3}x^3\right]_0^2\]\)

Plugging in the limits of integration, we have:

\(\[\frac{5}{3}(2)^3 - \frac{5}{3}(0)^3\]\)

Simplifying further:

\(\[\frac{40}{3}\]\)

Therefore, the value of the double integral is \(\(\frac{40}{3}\)\) or 13.333 (rounded to 3 decimal places).

100, 101, 102, 103, 104

Step-by-step explanation:

Basically, if the units (or ones, it's the same thing) digit of the first number is 0, the units digit of the second number should be 1, then 2, and so on. Therefore, one possible list of numbers is as follows: 100, 101, 102, 103, 104.

The probability of 45 heads in 100 tosses of a coin given the probability of heads is 50% is 7.1%.

The binomial probability formula is used to calculate the probability of getting a certain number of heads (or success) in a certain number of coin tosses (or trials) when the probability of getting a head (or success) in each individual coin toss is known. The formula is:

P(x) = (n choose x) * (pˣ) * (1-p)^(n-x)

Where,

P(x) is the probability of getting x heads (or success) in n coin tosses (or trials)

n is the number of coin tosses

x is the number of heads (or success)

p is the probability of getting a head (or success) in a single coin toss

1-p is the probability of getting a tail (or failure) in a single coin toss

(n choose x) is the binomial coefficient, which is the number of ways to choose x heads (or success) from n coin tosses (or trials)

In this case, the probability of getting 45 heads in 100 tosses of a coin with a probability of heads of 50% can be calculated using the formula: (100 choose 45) * (0.5⁴⁵) * (0.5⁵⁵) which is approximately 0.071, or 7.1%.
