Si lanzas una moneda 16 veces, ¿cuál es la mejor predicción posible para el número de veces que caerá cruz?

Using the average daily balance, the total balance on the next billing date, April 1 is $5,059.73.

The average daily balance is a credit card method of computing finance charges.

To determine the average daily balance, the sum of the daily balances over your billing cycle is divided by the number of days in the billing cycle.

The finance charge is then the product of the average daily balance multiplied by the APR and the number of days involved, divided by 365 days.

Average daily balance = $1,900

Unpaid balance at month-end = $1,700

APR = 32.4%

The finance charge for the month = $9.73 ($1900 x 32.4% x 30/365)

The total balance on the next billing date, April 1 = $5,059.73 ($5,050 + $9.73)

Thus, on April 1, the next billing cycle, the balance on the card is $5,059.73.

Okay, here are the steps to solve this problem:

* There are 10 sections on the spinner, 3 of which are green and 7 of which are yellow.

* So there is a 3/10 = 0.3 probability that the spinner will land on green.

* A fair coin has a 1/2 probability of landing on heads.

* For the spinner and coin toss to both have the desired outcome (green and heads), we multiply their individual probabilities:

* 0.3 * 1/2 = 0.15

Therefore, the probability that the spinner lands on green and the coin toss is heads is 0.15.

Answer:

  $1070.16

Step-by-step explanation:

You want the prorated amount of taxes if the annual amount is $1743.25 and the sale closes August 12, based on a 360 day year.

A 360-day year assumes months are 30 days. The tax charged to the seller will be that for 7 months plus 11 days:

  (7·30 +11)/360 × $1743.25 = $1070.16

The seller will pay $1070.16 of the tax bill.

We have presumed the buyer pays the taxes for August 12, the first day they own the property.

15.048 deciliters is equivalent to 1 quart.

Conversion is the process of changing a quantity from one unit of measure to another unit of measure using a conversion factor or a formula.

We have:

To convert meters to feet, multiply by 3.28.

To convert liters to gallons, multiply by 0.26.

To convert kilograms to pounds, multiply by 2.20.

To convert deciliters to quarts, divide by 15.048.

Let's use these conversions to convert the given measurement:

15.048 dL = qt

Dividing both sides by 15.048, we get:

1 dL = qt/15.048

Multiplying both sides by 0.946353, which is the number of quarts in a liter, we get:

0.946353 dL = qt/15.048 * 0.946353

Simplifying the right-hand side, we get:

0.946353 dL = qt/15.961

Multiplying both sides by 3.78541, which is the number of liters in a gallon, we get:

3.78541 * 0.946353 dL = 3.78541 * qt/15.961

Simplifying the left-hand side, we get:

3.58702 L = qt/4.22676

Multiplying both sides by 4.22676, we get:

15.1485 L = qt

Answer:

Step-by-step explanation:

The polynomial f(x) with real coefficients, degree 4, and zeros 6 (multiplicity 2), 3i can be formed as follows:

Since the zero 6 has a multiplicity of 2, it appears twice in the factored form of f(x), i.e., (x-6)(x-6) = (x-6)^2.

The other zero is 3i, which means its complex conjugate, -3i, is also a zero. Therefore, the factored form of f(x) can be written as:

(x-6)^2(x-3i)(x+3i)

Expanding this expression, we get:

f(x) = (x-6)^2(x^2 + 9)

Multiplying this out, we get:

f(x) = x^4 - 12x^3 + 81x^2 - 216x + 324

Therefore, the polynomial f(x) with real coefficients, degree 4, and zeros 6 (multiplicity 2), 3i can be written as:

f(x) = x^4 - 12x^3 + 81x^2 - 216x + 324.

The expression (cscx + cotx)² is the same as csc²x + 2(cscx)(cotx) + cot²x. (option a).

The given expression is (cscx + cotx)². To simplify this expression, we can use the formula for squaring a binomial, which is (a + b)² = a² + 2ab + b². In this case, a = cscx and b = cotx. Therefore, we can substitute these values into the formula to get:

(cscx + cotx)² = csc²x + 2(cscx)(cotx) + cot²x

So the expression (cscx + cotx)² is the same as csc²x + 2(cscx)(cotx) + cot²x.

Hence the correct option is (a).

The distance that the ball has traveled when the height of the ball is 80 feet is either about 9.86 feet or about 3.64 feet.

We are given that;

Velocity= 140feet

Inclination= 45degrees

Function  ​h(x)=(-32x^2/140^2)+x

Now,

To find the distance that the ball has traveled when the height of the ball is 80 feet, we need to solve the equation:

h(x) = 80

Substituting h(x) with the given function, we get:

(-32x2/1402) + x = 80

Multiplying both sides by 140^2 and simplifying, we get:

-32x^2 + 140x - 11200 = 0

Dividing both sides by -32 and simplifying, we get:

x^2 - (35/4)x + 350 = 0

Using the quadratic formula, we get:

x = [ (35/4) ± √( (35/4)^2 - 4(350) ) ] / 2 x ≈ 9.86 or x ≈ 3.64

Using a graphing utility, we can confirm that these are the approximate x-intercepts of the function h(x) - 80.

We can use the standard normal distribution to calculate probabilities for a normal distribution with mean 33 and standard deviation 4. We just need to standardize the intervals using the formula:

z = (x - mu) / sigma

where x is the specific value in the interval, mu is the mean, sigma is the standard deviation, and z is the corresponding z-score.

a. Between 29 and 37:

z1 = (29 - 33) / 4 = -1

z2 = (37 - 33) / 4 = 1

Using a standard normal distribution table, the cumulative probability of z being between -1 and 1 is approximately 0.6827.

So the probability that a randomly selected x-value from the distribution is between 29 and 37 is approximately 0.6827.

b. Between 33 and 45:

z1 = (33 - 33) / 4 = 0

z2 = (45 - 33) / 4 = 3

The cumulative probability of z being between 0 and 3 is approximately 0.4987.

So the probability that a randomly selected x-value from the distribution is between 33 and 45 is approximately 0.4987.

c. At least 29:

z = (29 - 33) / 4 = -1

The cumulative probability of z being less than -1 is approximately 0.1587. So the probability that a randomly selected x-value from the distribution is at least 29 is approximately 1 - 0.1587 = 0.8413.

d. At most 21:

z = (21 - 33) / 4 = -3

The cumulative probability of z being less than -3 is very close to 0. So the probability that a randomly selected x-value from the distribution is at most 21 is approximately 0.

Answer:

  (-4, 2)∪(8, ∞)

Step-by-step explanation:

Given a particle's position is described by x(t) = t³ -6t² -96t, you want the intervals where speed is increasing.

The speed of the particle is the magnitude of its rate of change of position.

The rate of change of position is ...

  x'(t) = 3t² -12t -96 = 3(t² -4t) -96

  x'(t) = 3(t -2)² -108

This describes a parabola that opens upward, with a vertex at (2, -108). It has zeros at x = 2 ± 6 = {-4, 8}.

The magnitude of the speed is shown by the blue curve in the attachment. Between t=-4 and t=8, it is the opposite of the parabola described by the above equation.

The rate of change of speed is the derivative of speed with respect to time. The green curve in the attachment shows the particle's rate of change of speed. Speed is increasing when the green curve is above the x-axis.

Between the point when speed is 0, at t=-4, and when it reaches a local maximum, at t=2, it is increasing. Speed is increasing again after it becomes 0 at t=8.

The intervals of increasing speed are (-4, 2) ∪ (8, ∞).

Additional comment

We have made the distinction between speed and velocity. Velocity is the signed rate of change of position. If position is plotted on a number line increasing to the right, then velocity is positive anytime the particle is moving to the right. Velocity is increasing if acceleration is to the right (positive).

Velocity of this particle is increasing on the interval (2, ∞).

The intervals in which the function is decreasing. [tex][-\pi , -\frac{\pi }{3} ], [\frac{\pi }{3}, \pi ][/tex]. Option 3

We're given a function f(x) = 2 sin x - x, which describes a curve on a graph. We want to find the intervals where this curve is decreasing (going down) within the range of -π to π.

To find when the function is decreasing, we look at its slope. The slope tells us if the curve is going up or down. We find the slope by taking the first derivative of the function: f'(x) = 2 cos x - 1.

We now have an equation for the slope, f'(x) = 2 cos x - 1. A negative slope means the function is decreasing. So, we want to find where f'(x) is less than 0 (negative).

We set up the inequality: 2 cos x - 1 < 0. We solve it to find the x-values where the slope is negative. The solution is cos x < 1/2.

From the inequality cos x < 1/2, we find the intervals within the range of -π to π where the function is decreasing. These intervals are [-π, -π/3] and [π/3, π].

The freighter is approximately 164.33 miles from the city.

We can use the Law of Cosines to solve this problem. Let's label the distances as follows:

d: distance between the city and the freighter

x: distance between the city and the island

y: distance between the island and the freighter

First, we need to find x using the given coordinates:

N23°38'W is equivalent to S23°38'E, so we have:

cos(23°38') = x/48

x = 48cos(23°38') ≈ 42.67 miles

Next, we can use the coordinates of the freighter to find y:

N11°26'E is equivalent to E11°26'N, and N12°16'W is equivalent to S12°16'E. This means that the angle between the island and the freighter is:

23°38' + 11°26' + 12°16' = 47°20'

cos(47°20') = y/d

We can rearrange this equation to solve for y:

y = dcos(47°20')

Now we can use the Law of Cosines to solve for d:

d² = x² + y² - 2xy cos(90° - 47°20')

d² = 42.67² + (d cos(47°20'))² - 2(42.67)(d cos(47°20')) sin(47°20')

d² = 1822.44 + d² cos²(47°20') - 2(42.67)(d cos(47°20')) sin(47°20')

d² - d² cos²(47°20') = 1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')

d² (1 - cos²(47°20')) = 1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')

d² sin²(47°20') = 1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')

d² = (1822.44 - 2(42.67)(d cos(47°20')) sin(47°20')) / sin²(47°20')

d ≈ 164.33 miles
