Answer:

The Poisson probability distribution gives the probability of a number of events occurring in a fixed interval of time or space if these events happen with a known average rate and independently of the time since the last event. For example, a book editor might be interested in the number of words spelled incorrectly in a particular book. It might be that, on the average, there are five words spelled incorrectly in 100 pages. The interval is the 100 pages.

Answer:

$286 per hour

Step-by-step explanation:

first we have to find out what 30% of $220 is

we do this by multiplying $220 by 0.3

We get $66

then we add the markup value to the initial value

$66 + $220= $286

Answer:

c = 40

Step-by-step explanation:

The correct answer is A. The selling price of a bond is affected by the coupon rate and the market interest rate.

If the coupon rate is less than the market interest rate, investors will not be interested in buying the bond because they can get a higher return elsewhere. This results in the selling price of the bond being less than its face value of $10,000.
The selling price of a $10,000 5-year bond will be less than $10,000 if the:
A. Coupon rate is less than the market interest rate

This is because when the coupon rate (the interest paid by the bond) is lower than the market interest rate, investors would prefer to invest in other options that offer a higher return. Therefore, to attract buyers, the bond's selling price would be discounted to compensate for the lower coupon rate.

Answer:

\(x = -3~\text{and}~ x = -\dfrac 35\)

Step-by-step explanation:

To Find:

Soln:

Use quadratic formulae:

\( \rm x=\cfrac{-b\pm\sqrt{b^2-4ac}}{2}\)

According to the question,on the formula,

So substitute them on the formula:

THEN solve for x.

\( \rm \implies \: x = \cfrac{-1 8 \pm \sqrt{18 {}^{2} - 4(5 \times 9) }}{2 \times 5} \)

\( \rm \implies \: x = \cfrac{-1 8 \pm \sqrt{324- 20 \times 9) }}{10} \)

\(\rm \implies \: x = \cfrac{-1 8 \pm \sqrt{324- 180}}{10} \)

\( \rm \implies \: x = \cfrac{ - 18 \pm \sqrt{144} }{10} \)

\( \rm \implies \: x = \cfrac{ - 18 \pm12}{10}\)

\( \rm \implies \: x = \cfrac{9 \pm 6}{5} \)

Final solution will after adding first(9+6),then secondly subtracting both 9-6

\( \rm \implies \boxed{x = - \cfrac{3 }{5} }\)

\( \implies \boxed{\rm x = - 3}\)

The sampling method used here is stratified random sampling.

The sampling method used in this scenario is called stratified random sampling.

In stratified random sampling, the population is divided into subgroups or strata based on certain characteristics, and then a random sample is selected from each stratum. In this case, the student selected 10 textbooks from each of the 22 randomly selected subjects.

By selecting textbooks from each subject, the student ensured that the sample represented different areas of study at the school. This approach helps to capture the variability present in different subjects and provides a more comprehensive representation of the population.

The use of stratified random sampling allows for a more accurate estimation of the overall mean and standard deviation of the textbooks' prices across different subjects. It also helps to reduce the potential bias

that could arise from selecting textbooks from only a few subjects or from subjects with extreme price ranges.

Therefore, the sampling method used here is stratified random sampling.

Have a great day!

P.S it can also be 21/8

Answer:

y= 4

x=8

Step-by-step explanation:

30-60-90 rule. the side opposite of 30 degrees is y, the side opposite of 90 degrees is 2y, and the side opposite of 60 degrees is y  \(\sqrt{3}\). since 4 is next to the square root that makes it y. y = 4 and 2y= 8.

The equation in slope-intercept form that represents the data in the table.

is 90 = 30x + 30.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A table shows the costs for art show participants, including the $30 registration fee.

From the table when x = 0, y = 30, and when x = 2, y = 90.

(0, 30), (2, 90).

We know slope(m) = (y₂ - y₁)/(x₂ - x₁) = (90 - 30)/(2 - 0) = 60/2 = 30.

∴ y = mx + b.

90 = 30x + 30.

Answer:

v=20π ft/s

Step-by-step explanation:

Given:

Distance from the security car to the movie theater, D=25 ft

Distance of the reflection from the car, d=30 ft

Speed of rotation of the strobe lights, 2 rev/s

To find the speed at which the reflection of the security strobe lights is moving along the wall of the movie theater, we need to calculate the linear velocity of the reflection when it is 30 ft from the car.

We can start by finding the angular velocity in radians per second. Since the strobe lights rotate at 2 revolutions per second, we can convert this to radians per second.

ω=2πf

=> ω=2π(2)

=> ω=4π rad/s

The distance between the security car and the reflection on the wall of the theater is...

r=30-25= 5 ft

The speed of reflection is given as (this is the linear velocity)...

v=ωr

Plug our know values into the equation.

v=ωr

=> v=(4π)(5)

∴ v=20π ft/s

Thus, the problem is solved.

The speed of the reflection of the security strobe lights along the wall of the movie theater is 2π ft/s.

To solve this problem, we can use the concept of related rates. Let's consider the following variables:

x: Distance between the security car and the movie theater wall

y: Distance between the reflection of the security strobe lights and the security car

θ: Angle between the line connecting the security car and the movie theater wall and the line connecting the security car and the reflection of the strobe lights

We are given:

x = 25 ft (constant)

y = 30 ft (changing)

θ = 2 revolutions per second (constant)

We need to find the speed at which the reflection of the security strobe lights is moving along the wall (dy/dt) when the reflection is 30 ft from the car.

Since we have a right triangle formed by the security car, the movie theater wall, and the reflection of the strobe lights, we can use the Pythagorean theorem:

x^2 + y^2 = z^2

Differentiating both sides of the equation with respect to time (t), we get:

2x(dx/dt) + 2y(dy/dt) = 2z(dz/dt)

Since x is constant, dx/dt = 0. Also, dz/dt is the rate at which the angle θ is changing, which is given as 2 revolutions per second.

Plugging in the known values, we have:

2(25)(0) + 2(30)(dy/dt) = 2(30)(2π)

Simplifying the equation, we find:

60(dy/dt) = 120π

Dividing both sides by 60, we get:

dy/dt = 2π ft/s

Answer:

Step-by-step explanation:

The price of one senior citizen ticket is $8 and that of a child ticket is $3.

Let the price of one senior citizen ticket be x

and the price of one student ticket be y

Thus, for the first day, we can make the following equation-

7x + 6y = 69

and similarly, we can make an equation for the second day as-

7x + 4y = 53

Now, we can solve these two linear equations to find the value of x and y.

Subtracting equation 2 from 1 we get-

(7x + 6y) - (7x + 4y) = 69 - 53

7x - 7x + 6y - 4y = 16

6y - 4y = 16

2y = 16

y = 16/2

y = 8

Substituting the value of y in any of the two equations we can find the value of x-

7x + 6(8) = 69

7x = 69 - 48

x = 21/7

x = 3

Thus, the price of one senior citizen ticket is $8 and that of a child ticket is $3.

Answer:

Step-by-step explanation:

The opposite angles in a cyclic quadrilateral are supplementary. The sum of the opposite angles is equal to 180˚

x+100=180

x=180-100=80

90 - 53.45 = 36.55

36.55 / 7.31 = 5 pounds of coffee

5000 square feet is the largest area that can be enclosed

It is given that a rectangular plot is to be fenced off and divided into three parts/plots on land that borders a barn there are and there is 200 feet of fence that is available.

One-fourth of the perimeter = 50

The other width also equals 50.

So the length of fencing = 200 - 50 - 50 = 100

So the area = 50 x 100 = 5000 square feet.

90=5*3*5*2*3

So, HCF=15

Step-by-step explanation:

Hope it helps

Step-by-step explanation:

Hey there!

HCF stands for highest common factor. When you are asked about to find the HCF of any number find the factors and take common from all the factors of the numbers.

The given numbers are: 15,30,90.

15 = 3*5

30 = 2*3*5

90 = 2*3*3*5

Now, from the above solutions take all the common factors.

From the factors of all three numbers, 3*5 are common.

Therefore, the HCF of the numbers is 3*5 = 15.
