The probability of getting orange 21% more in that large bag is 0.
How to calculate the probability?Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur or that a particular statement is true.
In this situation, the company claims that in the large bag of M&M's 20% of them were orange. Since the oranges are 20%, the probability of getting orange 21% more in that large bag is not possible. This will be zero.

Angle
v = 180°
(14cos45° + 70cos180°, 14sin45° + 70sin180°) = (17.9, -55.1) is the component form of the sum of u and v with direction angles u and v.
What's an angle?The amount of rotation that occurs between two planes or straight lines is what is meant to be meant by the geometrical term "angle." A full circle is 360 degrees, and an angle is measured in degrees. Right angles (90 degrees), acute angles (less than 90 degrees), and obtuse angles (more than 90 degrees) are the most prevalent types of angles. Depending on how they relate to one another, angles can also be broken down into complementary or supplementary categories. The sum of complementary and supplementary angles is 90 degrees, while the sum of the two is 180 degrees.
Component form :The vector addition formula can be used to determine the component form of the sum of u and v. According to this formula, the direction angle of the vector sum is equal to the arctangent of the ratio of the sum of the y-components of the two vectors to the sum of the x-components of the two vectors, while the magnitude of the vector sum of two vectors is equal to the square root of the sum of the squares of each vector's magnitude.
The component form of the sum of the given vectors u and v is as follows:
Magnitude = √(14²) + (70²)) = 70.45
The direction angle is arctan((14 × sin(45) + 70×sin(180)) / (14×cos(45) + 70×cos(180)))

The outside tempature dropped 20°F from the time arianna ate breakfast until the time she ate dinner. When she ate dinner the tempature was 35°F. Write and solve an equation to find the outside tempature t when arianna ate breakfast
The outside temperature t when Arianna ate breakfast was 55°F.
An equation is a mathematical statement showing that two expressions are equal. It is written with an equal sign (=) between two expressions, with one expression on the left side of the equal sign, and the other expression on the right side.
According to the given statements-
Let the outside temperature at the time of breakfast be t°F.
The temperature dropped by 20°F by the time of dinner.
So the temperature at the time of breakfast = t - 20
Also, when she ate dinner the temperature was 35°F
So the equation for outside temperature t when Arianna ate breakfast will be -
t - 20 = 35
Simplifying we get,
t = 35 + 20
t = 55°F
Hence, the outside temperature t when Arianna ate breakfast was 55°F.

suppose you own a swimming pool with dimensions 4.93 m x 9.69 m x 1.75 m. what is the volume of your pool in gallons?
22084.78 gallons is the volume of your pool.
Any rectangular solid's volume, V, is equal to the sum of its dimensions, height, width, and depth. In terms of the area of the base, we might alternatively express the formula for a rectangular solid's volume. The base's surface area, B, is equal to its length x width.
Dimensions of the pool = 4.93 m x 9.69 m x 1.75 m
Volume = 4.93 x 9.69 x 1.75
= 83.6 cubic meter
1 cubic meter = 264.172 gallons
83.6 cubic meter = 83.6 x 264.172
= 22084.78 gallons

15 foot ladder leaning agaisnt a building touches the wall 12 feet above the ground how far from the building is the bottom of the ladder
The bottom of the ladder is 9 feet from the wall.
Using the Pythagorean Theorem, we can calculate the distance from the wall. The Pythagorean Theorem states that for a right triangle, the sum of the squares of the sides is equal to the square of the hypotenuse. In this case, the hypotenuse is 15 feet and the side adjacent to the wall is 12 feet.
The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.
We can solve for the distance from the wall (a). a^2 = c^2 - b^2, so a^2 = 15^2 - 12^2, which equals a^2 = 225 - 144, so a^2 = 81. Taking the square root of both sides, a = 9 feet.

for a random sample of 100 people, what is the probability that the sample mean will be within 5 points of the population mean
The probability that the sample mean will be within 5 points of the population mean is 0.95 or 95%
Central Limit TheoremThe Central Limit Theorem (CLT), a foundational idea in statistics, holds that, regardless of the underlying population distribution, the distribution of the sample means will be about normal given a big enough sample size. The CLT is crucial because it enables us to draw conclusions about a population based on a sample, even when the population is not normal.
According to the CLT, as the sample size grows, sample means will approach population means and their standard deviations will fall. The standard error, also known as the standard deviation of the sample means, is calculated by dividing the standard deviation of the population by the square root of the sample size.
According to the Question
The sample mean for a random sample of 100 individuals is most likely to be within 5 points of the population mean. The distribution and standard deviation of the population, however, would determine the precise likelihood. The standard error may be used to determine a confidence interval for the population mean if the population standard deviation is known. A 95% confidence interval is frequently used, which is equivalent to 1.96 standard deviations from the mean. In this instance, especially with a large sample size, there is a good likelihood that the sample mean will be within 5 points of the population mean.

a certain museum has five visitors in two minutes on average. let a poisson random variable denote the number of visitors per minute to this museum. find the probability that this museum gets at least three visitors in a minute (round off to second decimal place).
The exact probability that this museum gets at least 3 visitors in a minute is approximately 0.224
A Poisson distribution is a probability distribution that models the number of times an event occurs within a given time or space, if these events are rare and independently of the time since the last event. The Poisson distribution is characterized by the mean number of occurrences λ in a given interval.
In this case, the mean number of visitors per minute is λ = 5 visitors / 2 minutes = 2.5 visitors per minute.
We can use the Poisson probability mass function to find the probability that this museum gets at least 3 visitors in a minute.
To find the probability that this museum gets at least 3 visitors in a minute by using:
1 - P(X < 3)
Where X is the number of visitors in a minute and 3 is the lower limit of the number of visitors we want to include in the sample.
Thus, P(X>=3) = 1 - P(X < 3) = 1 - 0.776 = 0.224

Elle can buy maximum 0.6 liters of goat milk and 1.2 liters of cow's milk.
What System of linear inequalities?
A system of linear inequalities is similar to a system of linear equations, except that it is made up of inequalities rather than equations. To represent scenarios with various restrictions, systems of linear inequalities are utilized.
Let x be the number of liters of goat milk and y be the number of liters of cow's milk that Elle wants to buy. We know that:
x + y ≤ 80 (because Elle wants to spend at most Php80)
130x + 65y ≤ 80 (because each liter of goat milk costs Php130 and each liter of cow's milk costs Php65)
This is a system of linear inequalities, and the solution set is the set of all possible combinations of x and y that satisfy both inequalities.
The inequality 130x + 65y ≤ 80 represents a line in the plane, and the inequality x + y ≤ 80 represents a region that is "bounded" by this line.
The solution set for the inequalities are x <= 0.6 and y <= 1.2.
