suppose that 12 different people call you in a week. what is the probability you will get at least one phone call per day (assume 7 days in the week)? use a mc simulation to estimate this probability with a margin of error of 0.005.

Answer:

Yes

Step-by-step explanation:

To determine whether a relation is a function or not, we can do a vertical line test. First, get something like a ruler, put it vertical, then scan it on the relation. If the ruler hits one point of the line, then it is a function. If the ruler hits two points at once, then it is not a function. This passes the vertical line test, because when the ruler hits the relation it only hits one point at a time, making it a function. I hope this helps, I hope it's not wrong but I don't think it is.

The area of figure ABCDE is 26.5 square units.

Three angles, three sides, and three vertices make up the closed shape of a triangle. It is one of the most fundamental geometric shapes, and the symbol for it is.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape

Given:

Area of triangle ABC = 7.95 square units

Area of triangle ACD = 9.8 square units

Area of triangle AED = 8.75 square units

To calculate the area of the figure we have to add the area of the individual triangles together.

So, Area of figure ABCDE

= Area of triangle ABC + Area of triangle ACD + Area of triangle AED

= 7.95 + 9.8 + 8.75

= 26.5 square units

The smallest number of eggs that could have been in the box is 1134

The problem is to find the smallest number of eggs that could have been in the box, given the remainder when taking them out by different numbers. Here are the moves toward tackling it:

Allow n to be the quantity of eggs in the container. Then we have the accompanying arrangement of congruences:

n ≡ 1 (mod 2)

n ≡ 1 (mod 3)

n ≡ 1 (mod 4)

n ≡ 1 (mod 5)

n ≡ 1 (mod 6)

n ≡ 0 (mod 7)

For this problem, we have k = 6 k = 6, a i = {1,1,1,1,1,0} a_i = {1,1,1,1,1,0}, M i = {1260,840,630,504,420,720} M_i = {1260,840,630,504,420,720}, and y i = {−1,−2,−3,-4,-5,-6} y_i = {-1,-2,-3,-4,-5,-6}.

Plugging these values into the formula and simplifying modulo 5040, we get:

n = (−1260 + −1680 + −1890 + −2016 + −2100 + 0) mod 5040

n = (−8946) mod 5040

n = (−3906) mod 5040

n = 1134 mod 5040

Therefore, the smallest number of eggs that could have been in the box is 1134

The difference between the median of the data including the possible outlier and excluding the possible outlier is 15.5.

To find the difference between the median of the data including the possible outlier and excluding the possible outlier, we first need to determine the median of the data.

The given data set is: 55, 52, 50, 47, 68, 48, 53, 53

Arranging the data in ascending order: 47, 48, 50, 52, 53, 53, 55, 68

The median is the middle value of the data set. Since the data set has an even number of values, the median is the average of the two middle values. In this case, the two middle values are 52 and 53, so the median is (52 + 53) / 2 = 52.5.

Now we can calculate the difference between the median including the possible outlier (68) and excluding the possible outlier.

Difference = Median (including outlier) - Median (excluding outlier)

= 68 - 52.5

= 15.5

The incenter is the intersection of the angle bisectors, the distances from the incenter to the sides are proportional to the lengths of the adjacent sides, which gives the desired proportionality.

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.

To sketch the segments representing the distance from the incenter to the sides of a triangle, we draw perpendiculars from the incenter to each of the sides, as shown in the attached image.

The segments representing the distances from the incenter P to the sides of the triangle are the inradii.

Let r1, r2, and r3 be the lengths of the inradii corresponding to sides AB, BC, and AC, respectively.

Then, we have:

r1 = distance from P to AB

r2 = distance from P to BC

r3 = distance from P to AC

To compare these distances, we use the fact that the incenter is the intersection of the angle bisectors of the triangle.

Therefore, the distance from the incenter to each side is proportional to the length of the corresponding side. More precisely, we have:

r1 : r2 : r3 = AB : BC : AC

This proportionality can be proved using the angle bisector theorem, which states that the length of the segment of an angle bisector in a triangle is proportional to the lengths of the adjacent sides.

Hence, the incenter is the intersection of the angle bisectors, the distances from the incenter to the sides are proportional to the lengths of the adjacent sides, which gives the desired proportionality.

The probability of selecting a human character randomly in the game is \(\frac{1}{3}\)

The probability that a human character will be chosen when the player selects a character randomly can be calculated by dividing the number of human characters by the total number of available characters.

There are 8 animal characters and 4 human characters, making a total of 12 characters to choose from. Therefore, the probability of selecting a human character randomly is:

P(Human) = Number of human characters / Total number of characters

P(Human) = 4 / 12

Simplifying this fraction, we find:

P(Human) = 1 / 3

Therefore, the probability of selecting a human character randomly is 1/3 or approximately 0.333.

In the given scenario, there are a total of 8 animal characters and 4 human characters, making a total of 12 characters to choose from. When a player selects a character randomly, each character has an equal chance of being chosen. Since there are 4 human characters, the probability of selecting one of them is determined by dividing the number of human characters (4) by the total number of characters (12).

When we simplify the fraction 4/12, we find that it is equal to 1/3.

The correct option is (C). No, because the sum of the probabilities is more than one.

In mathematics, a probability distribution is a function that expresses the likelihood of many possible values for a variable. Graphs and probability tables are common ways of displaying probability distributions.

In the given table, the probabilities are,

P(x) = 0.2, 0.3, 0.4, 0.1 and 0.05.

The sum of the probabilities = 0.2 + 0.3 + 0.4 + 0.1 + 0.05

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \(\frac{x_{1}+x_{2} }{2}\) , \(\frac{y_{1}+y_{2} }{2}\) )

here the endpoints are R (- 11, - 12 ) and T (- 7, - 4 ) , then

midpoint = ( \(\frac{-11-7}{2}\) , \(\frac{-12-4}{2}\) ) = ( \(\frac{-18}{2}\) , \(\frac{-16}{2}\) ) = (- 9, - 8 )

It is true that the expressions 5y + 4 − 3y = 2y + 4 are equivalent

From the question, we have the following expression that can be used in our computation:

5y+4−3y = 2y+4

This equation can be rewritten as follows

So, we have the following representation

5y + 4 − 3y = 2y + 4

Collect the like terms in the above equation

This gives

5y − 3y + 4 = 2y + 4

Evaluate the like terms in the above equation

The inequality that correctly describes the number of ounces of water, w, that tom drinks each day is d. 64<w.

Amount of water that the bottle can hold = 32 ounces

Bottles of water consumed = 2

A mathematical comparison and representation of the connection between two expressions is known as an inequality. It can be regarded as a generalisation of an equation and is denoted by signs such as <, > and =.

Tom consumes more than two complete bottles of water every day. Since each bottle can carry up to 32 ounces of water, we can describe Tom's daily water consumption as -
