when a coin is flipped n times,what is the probability that the first head comes after exactly m tails

Answer:

3.Yes, because triangle ABC has a 90 degree angle.

4.No, because triangle XYZ doesn’t have a 90 degree angle.

The sound intensity level due to a swarm of 100 bees will be higher than the intensity due to a single bee. This can be calculated using the logarithmic function. Therefore, the resulting increase in sound intensity level can be calculated by using the equation I100 = 10log(100I).

This property of the logarithmic function can be used to calculate the increase in sound intensity level due to larger groups of bees. By increasing the number of bees, the intensity of sound will also increase, as shown by this equation. Therefore, the logarithmic function can be used to calculate the relative difference in sound intensity level between single bee and a swarm of bees.

An example of independent events is P(Police Officers and choose cars).

When one event's occurrence or non-occurrence doesn't affect the occurrence or non-occurrence of another event, then such events are called independent events.

Symbolically, we have:

Two events A and B are said to be independent if we have:

P(A ∩ B) = P(A)P(B)

                    Police Officers         Firefighters

Cars               12                             3

Trucks            9                              4

SUVs              15                             2

Let  P(A) = Firefighters choose cars

P(B) = Firefighters choose Trucks

P(A ∩ B)  =  Police Officers choose cars

Thus,

P(A ∩ B) = P(A)P(B)

12 = (4) ( 3)

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Explanation:

If they stay until the end of the lease, total money that will be paid out is $1000 x 6 = $6000,

If they leave, they'll have to forgo $1000.

If they move to their new apartment, they'll pay $900 x 6 = $5400

total expenditure if they move to the new place at the end of the six months period will be, the $1000 that will not be refunded back to them on the old apartment, plus this new $5600 for six month's rent in this new apartment, and that will be a total of $6400.

Answer:

(a)Adult:10.99+0.99x, Kid: 5.99+0.99x

(b)Adult's Total cost = $15.94, Kid's Total cost =$10.94

Explanation:

Cost of a ride = $0.99

Let x be the number of rides.

Cost of an Adult Ticket = $10.99

An equation for adult tickets will therefore be: 10.99+0.99x

Similarly, the cost of a kid ticket =$5.99

An equation for adult tickets will therefore be: 5.99+0.99x

(b)If they ride 5 tickets each, the amount of money spent will be:

x=5 rides

Total cost for an adult=10.99+0.99(5)

=10.99+4.95

=$15.94

Total cost for a kid = 5.99+0.99(5)

=5.99+4.95

=$10.94

The amplitude, midline and period of the function are 3 units, 4units and 5 units respectively

The amplitude is half the full height of the periodic function. That is:

Amplitude = (maximum - minimum)/2

Check the image attached, the maximum and minimum are labeled max and min respectively

Amplitude = (-1 - (-7))/2  = 6/2 = 3 units

The midline is the middle of the periodic graph or halfway between the minimum and maximum of the graph

Midline = (maximum + minimum)/2

Midline = (-1 + (-7))/2 = -8/2 = -4 units

The period is the distance between two peaks or (maximums) on the graph.

Period = 1-(-4) = 5 units

Therefore, the amplitude, midline and period are 3 units, 4units and 5 units respectively

The dimensions of the rectangle that will produce the largest area of the window are x = (12 - √3) / 2 and y = 3 / √3.

Let x be the length of the rectangle, and y be the width of the rectangle. The perimeter of the window is 12m, and since the triangle is equilateral, we know that all 3 sides of the triangle are equal to x.

Therefore, we can set up the following equation to represent the perimeter of the window: x + y + x = 12

The area expression is:

A = x*y + (x^2 * √3)/4

After substituting x = (12-y)/2, the area expression becomes:

A = [((12-y)/2)*y] + [(12-y)^2 * √3]/16

Which can be simplified to:

A = 6y - 3y^2 + (9-3y)√3 / 4

To find the maximum value of this expression, we can differentiate it with respect to y and set it to zero:

dA/dy = -3y + (9-3y)√3/4 = 0

and solve for y:

-3y + (9-3y)√3/4 = 0

-3y = (3y-9)√3/4

-3y = 3y-9 / 2√3

3y = 9 / 2√3

y = 3 / √3

To find x, we can substitute this value of y back into x = (12-y)/2:

x = (12 - 3 / √3) / 2 = (12 - √3) / 2

So the dimensions of the rectangle that will produce the largest area of the window are x = (12 - √3) / 2 and y = 3 / √3.

Answer: x=68° because this triangle is a isoscele triangle which means that it haves 2 sides that are congruent and equivalent which means they have the same value and sides and are Congruent just means In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

The value of angle [x] is equivalent to 44°.

We have a triangle as shown.

We know, the angles opposite to equal sides are equal.

So, we can write -

x + 68° + 68° = 180°

x = 180° - (136°)

x = 44°

Therefore, the value of angle [x] is equivalent to 44°.

SOH = opposite over hypotenuse

Step-by-step explanation:

The expression that is always equivalent to sin x when 0° < x < 90° is (1) cos (90° - x). Option 1

To understand why, let's analyze the trigonometric functions involved. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. Since we are considering angles between 0° and 90°, we can guarantee that the side opposite the angle will always be the shortest side of the triangle, and the hypotenuse will be the longest side.

Now let's examine the expression cos (90° - x). The cosine of an angle is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. In a right triangle, when we subtract an angle x from 90°, we are left with the complementary angle to x. This means that the remaining angle in the triangle is 90° - x.

Since the side adjacent to the angle 90° - x is the same as the side opposite the angle x, and the hypotenuse is the same, the ratio of the adjacent side to the hypotenuse remains the same. Therefore, cos (90° - x) is equivalent to sin x for angles between 0° and 90°.

On the other hand, options (2) cos (45° - x) and (3) cos (2x) do not always yield the same value as sin x for all angles between 0° and 90°. The expression cos x (option 4) is equivalent to sin (90° - x), not sin x.

Option 1 is correct.

Let X be the total number of employees.

Total employees in one country = 26,800.

33.6% of X = 26800
