binomial a lottery will be held. from 1000 numbers, one will be chosen as the winner. a lottery ticket is a number between 1 and 1000. how many tickets do you need to buy in order for the probability of winning to be at least 50%?

Answers

Answer 1

we need to buy at least 694 tickets to have a probability of winning at least 50%.

We can use the binomial distribution formula to solve this problem. Let X be the number of tickets we need to buy to have a probability of winning at least 50%. Then:

P(X ≥ 1) ≥ 0.5

This means that the probability of winning with at least one ticket is at least 50%. We can find this probability using the complement rule:

P(X ≥ 1) = 1 - P(X = 0)

The probability of not winning with any ticket is:

P(X = 0) = (999/1000)^n

where n is the number of tickets we buy. Therefore:

1 - (999/1000)^n ≥ 0.5

Simplifying this inequality, we get:

(999/1000)^n ≤ 0.5

Taking the logarithm of both sides, we get:

n log(999/1000) ≤ log(0.5)

n ≥ log(0.5) / log(999/1000)

n ≥ 693.15

Therefore, we need to buy at least 694 tickets to have a probability of winning at least 50%.

Write a rule for g that represents a vertical stretch by a factor of 6, followed by a translation 5 units down of the graph of f(x)=log0x

Answers

the rule for g that represents a vertical stretch by a factor of 6, followed by a translation 5 units down of the graph of f(x) = log₀(x) is g(x) = 6log₀(x) - 5.

The given function is f(x) = log₀(x)

To stretch the graph of f(x) vertically by a factor of 6, we multiply f(x) by 6, which gives:

g(x) = 6log₀(x)

To translate the graph of g(x) down 5 units, we subtract 5 from g(x), which gives:

g(x) = 6log₀(x) - 5

the concept of factors can also be applied to functions. Given a function f(x), a factor of f(x) is another function g(x) such that f(x) can be written as the product of g(x) and another function h(x).a factor is a number or algebraic expression that divides another number or algebraic expression evenly, leaving no remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12 because each of these numbers can divide 12 without leaving a remainder.

you measure the radius of a wheel to be 4.16 cm. if you multiply by 2 to get the diameter, should you write the result as 8 cm or as 8.32 cm?

Answers

If you take a wheel's radius of 4.16 cm and divide it by 2 to get its diameter, you should write 8.32 cm instead of 8 cm.

The breadth of a circle is two times the sweep. Therefore, if the wheel has a radius of 4.16 cm, its diameter will be

2 x 4.16 = 8.32 cm.

If the measurement is going to be used for precise engineering or calculations, it is essential to write the result as 8.32 cm because this is a measurement that is more accurate than rounding it off to 8 cm. Working with the most accurate measurement is always preferable because rounding off can result in errors.

A piece of art is in the shape of a rectangular pyramid like the figure shown.

A rectangular pyramid with a base of dimensions 5 feet by 4 feet. The two large triangular faces have a height of 6.8 feet. The two small triangular faces have a height of 7 feet.

How much glass is needed to cover the entire pyramid?

82 ft2
164 ft2
62 ft2
41 ft2

Answers

Answer:

82 ft^2

Step-by-step explanation:

To find the amount of glass needed to cover the entire rectangular pyramid, we need to calculate the combined surface area of all its faces.

The rectangular base of the pyramid has an area of 5 feet by 4 feet, or 20 square feet. The two large triangular faces each have an area of (1/2) x base x height = (1/2) x 5 feet x 6.8 feet = 17 ft^2. The two small triangular faces each have an area of (1/2) x base x height = (1/2) x 4 feet x 7 feet = 14 ft^2.

Therefore, the total surface area of the pyramid is:

20 ft^2 (for the base) + 17 ft^2 + 17 ft^2 + 14 ft^2 + 14 ft^2 = 82 ft^2

So, the amount of glass needed to cover the entire pyramid is 82 square feet.

Therefore, the answer is 82 ft^2.

Answers

According to the given information, the two equations that are true for  x=-2  and  x=2  are  4x²-16=0  and  2(x-2)²=0.

What is an equation?

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equals sign (=). The expressions on both sides of the equation can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

The values of  x=-2  and  x=2  satisfy the equation  4x²=16, so  4x²-16=0  is true for both  x=-2  and  x=2.

The equation  x²=-4  has no real solutions, so it is not true for either  x=-2  or  x=2.

The equation  3x²+12=0  is not true for either  x=-2  or  x=2 , because  3x²+12  is always positive for any real value of  x .

The equation  2(x-2)²=0  is only true for  x=2 , because plugging in  x=-2  gives  2(-4)² =32 ≠0.

Therefore, the two equations that are true for  x=-2  and  x=2  are  4x²-16=0  and  2(x-2)²=0 .

Option D : Matching a 3D shape to its net requires visual spatial reasoning and knowledge of geometry.

A net is a two-dimensional pattern that can be folded to form a three-dimensional shape. It shows how the faces of a 3D shape are connected and arranged in a flat layout. The process of making a net involves taking apart a 3D object and flattening it out without stretching or bending any of the faces.

A net must accurately represent the dimensions and features of the 3D shape it represents, such as the shape and size of each face, the number of edges and vertices, and the angles between the faces.

Some common 3D shapes that can be represented by nets include cubes, pyramids, prisms, cylinders, and cones. Nets can be created using various methods, such as drawing them by hand, using computer software, or printing them from online sources. When constructing a 3D object from a net, it is important to fold and join the edges carefully to ensure that the final shape is accurate and stable.

Therefore, the correct net that matches the 3D shape is option D.

how many batteries n should be in the package in order for the probability to exceed 1%? give the smallest number n which works.

Answers

a) The probability that a battery does not reach the milestone in its first 8 hours of usage is 0.014 or 1.4%. b)  The probability of this goal being met is 0.002 or 0.2%. c) The smallest value of n that satisfies P(X >= 10) > 0.01 is n = 13.

(a) To calculate the probability that a battery does not reach the milestone in its first 8 hours of usage, we need to calculate the area under the normal curve to the right of 8 hours. We can use the standard normal distribution to do this by first standardizing the value of 8 hours using the formula:

z = (x - mu) / sigma

where x is the value of 8 hours, mu is the mean of the distribution (7.36 hours), and sigma is the standard deviation (0.29 hours). Substituting these values, we get:

z = (8 - 7.36) / 0.29 = 2.21

Using a standard normal table or a calculator, we can find that the area to the right of z = 2.21 is approximately 0.014.

(b) We want to find the probability that at least 10 batteries out of a pack of 12 last until 7.5 hours of usage. This is a binomial distribution with n = 12 and p = the probability that a single battery lasts until 7.5 hours.

To find p, we can use the standard normal distribution again by standardizing the value of 7.5 hours:

z = (7.5 - 7.36) / 0.29 = 0.48

Using a standard normal table or a calculator, we can find that the area to the right of z = 0.48 is approximately 0.316. Therefore, the probability that a single battery lasts until 7.5 hours is 0.316.

Now we can use the binomial distribution formula to calculate the probability that at least 10 batteries out of 12 last until 7.5 hours:

P(X >= 10) = 1 - P(X < 10)

where X is the number of batteries that last until 7.5 hours, and P(X < 10) is the cumulative probability of 9 or fewer batteries lasting until 7.5 hours. Using a binomial calculator or a standard normal table, we can find that:

P(X < 10) = 0.998

Therefore, P(X >= 10) = 1 - 0.998 = 0.002 or 0.2%.

(c) We want to find the smallest value of n such that the probability of at least 10 batteries out of n lasting until 7.5 hours is greater than 1%. This is equivalent to finding the smallest n such that:

P(X >= 10) > 0.01

Using a binomial calculator or a standard normal table, we can find that:

P(X < 10) = 0.989 when n = 10

P(X < 10) = 0.970 when n = 11

P(X < 10) = 0.942 when n = 12

Therefore, the smallest value of n that satisfies P(X >= 10) > 0.01 is n = 13.

a spinner with the colors red, yellow, blue, and green is spun. what is the theoretical probability of stopping on the color blue?

Answers

1/4 or 25% chance or .25, this is because there are four colors and blue is only one of them.

The theoretical probability of stopping on the color blue when spinning a spinner with the colors red, yellow, blue, and green is 25% or 1/4.

A spinner is a tool that spins around an arrow or a pointer that points towards the numbers, colors, or pictures around its edge. The probability of a certain event is the likelihood of that event occurring. In this case, we need to find the theoretical probability of stopping on the color blue.

We have four colors on the spinner, so the probability of stopping on blue can be found using the formula of theoretical probability.

The formula for theoretical probability is:

number of favorable outcomes / total number of outcomes.

Since we have four colors on the spinner, the total number of outcomes is 4. The favorable outcomes are the number of times the spinner will land on blue, which is 1.

So the probability of stopping on the color blue can be calculated as follows:

1 (favorable outcome) / 4 (total number of outcomes) = 1/4

So, the theoretical probability of stopping on the color blue is 1/4. This is because there is an equal chance of landing on any of the four colors, and since there are four colors, each has a 25% chance of being selected.

Explicit Formula:

The explicit formula for calculating the value of the necklace after t years, with an annual growth rate of r, can be given as:

V(t) = V(0) × (1 + r)ⁿ

Here, V(0) is the initial value of the necklace, which is $3200 in this case, and t is the number of years. The growth rate is 9%, which can be expressed as 0.09.

P(n,r) = n! / (n-r)!

Where n is the total number of individuals, and r is the number of positions to be filled.

In this case, we need to select 3 individuals out of 8 to fill the 1st, 2nd, and 3rd place positions. Using the permutation formula, we get:

P(8,3) = 8! / (8-3)!

To find the number of bicycles Aki's Bicycle Designs should build to minimize the average cost per bicycle, we need to find the minimum point of the given quadratic function C(x).

First, we can find the derivative of C(x) concerning x:

C'(x) = 0.4x - 0.7

Then, we can set C'(x) equal to zero and solve for x:

0.4x - 0.7 = 0

0.4x = 0.7

x = 1.75

9-112. Find the perimeter and area of the figure at right. Show your work for each of the steps that you use. P = 34m, A = 74 sq m

Answers

Therefore, the area of the figure is 48 square units.

What is Perimeter?

Perimeter is the total distance around the boundary of a two-dimensional shape. It is calculated by adding up the lengths of all the sides of the shape. The perimeter is usually measured in units such as inches, centimeters, or meters, depending on the size of the shape.

To find the perimeter of the figure, we add up the lengths of all the sides:

Given by the question.

Perimeter = 6 + 8 + 10 + 5 = 29

Therefore, the perimeter of the figure is 29 units.

To find the area of the figure, we need to use the formula for the area of a trapezoid, which is:

Area = (1/2) x (sum of parallel sides) x (distance between them)

The distance between the parallel sides is the height of the trapezoid. To find the height, we need to use the Pythagorean theorem, since the trapezoid is a right trapezoid.

[tex]a^{2}[/tex] + [tex]b^{2}[/tex]= [tex]c^{2}[/tex]

where a and b are the lengths of the legs of the right triangle, and c is the length of the hypotenuse.

In this case, a = 6, b = 8, and c = 10. So, we have:

[tex]6^{2}[/tex] + [tex]8^{2}[/tex] = [tex]10^{2}[/tex]

36 + 64 = 100

100 = [tex]10^{2}[/tex]

Therefore, the height of the trapezoid is:

h = [tex]\sqrt{c^{2}-b^{2} }[/tex] = [tex]\sqrt{10^{2}-8^{2} }[/tex]= √36 = 6

Now we can plug in the values for the sum of the parallel sides and the height to get the area:

Area = (1/2) x (6 + 10) x 6 = 48
