Answer:
The correct option is B.
Step-by-step explanation:
The median (m) is a measure of central tendency. To obtain the m, we assemble the data in arising order. If the data is odd, the m is the mid-value. If the data is even, the m is the arithmetic-mean of the two mid-values.
The mean is the average value of the data set. It is computed by dividing the sum of all the values in data set by the number of values.
So, the mean considers all the values in the data set. But the median considers only one value.
It is provided that the clerk entering salary data into a company spreadsheet accidentally put an extra "0" in the highest employee salary (the boss's salary!), listing it as $1,500,000 instead of $150,000.
The highest salary will be taken into account while the computation of mean. But it would not be considered while determining the median.
So, the median salary will remain same. But the mean salary will change.
And since the highest salary is increasing from $150,000 to $1,500,000 the mean will also increase.
Thus, the correct option is B.

If two triangles are congruent, then they will have the exact same sides and angle measures.
AB=3x+1
BC=6
DE=2x
Solve for X by making 2x=6 because DE and BC are corresponding sides, indicating they are equal.

Jordan and Micheal are planing a graduation party with 45 guests. They want to seat an equal number of guests at each table.Each table should have more than one guest.List te different ways the guests and tables could arranged. Tell how many tales are needed for each group of guests. guests at each table.Each table should have more than one guest.List different ways the guests and tables
Answer:9 tables with 5 people at each one
Step-by-step explanation:
Using the factorization that defines the arrangement, there can be 9 tables for 45 guests with 5 guests per table. "A large number is factorised, which is the process of breaking it down into smaller numbers that, when multiplied together, produce the original number. A number is factorised when it is divided into its factors or divisors."
What is factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics. The Grouping method, the Difference in Two Squares, the Sum or Difference in Cubes, and the Greatest Common Factor (GCF) are the four main methods of factoring. Divide a number by the smallest prime number (larger than 1) that divides it evenly and leaves no remainder to find its factors quickly. As you receive more numbers, repeat this procedure until you reach 1.
Here,

when we factorize 45,

We can arrange in the order of 5 guest on each table and their can be 9 tables for 45 guests using the factorization that defines "Factorization is the process of dividing a large number into smaller ones that, when multiplied together, yield the original number.

The number of road construction projects that take place at any one time in a certain city follows a Poisson distribution with a mean of 3. Find the probability that exactly four road construction projects are currently taking place in this city.
Answer:
The probability that exactly four road construction projects are currently taking place in this city is 0.168.
Step-by-step explanation:
Let X denote the number of road construction projects that take place at any one time in a certain city.
It is provided that X follows a Poisson distribution with parameter λ = 3.
Then the probability mass function of X is:
[tex]p_{X}(x)=\frac{e^{-\lambda}\cdot \lambda^{x}}{x!};x=0,1,2,3...[/tex]
Compute the probability that exactly four road construction projects are currently taking place in this city as follows:
[tex]P(X=4)=\frac{e^{-3}\cdot 3^{4}}{4!}[/tex]
[tex]=\frac{0.04979\times 81}{24}\\\\=0.16804125\\\\\approx 0.168[/tex]
Thus, the probability that exactly four road construction projects are currently taking place in this city is 0.168.
Using the Poisson distribution, it is found that there is a 0.1954 = 19.54% probability that exactly four road construction projects are currently taking place in this city.
We have only the mean for the discrete distribution, hence, the Poisson distribution is used.
Poisson distribution In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successes e = 2.71828 is the Euler number [tex]\mu[/tex] is the mean in the given interval.In this problem, the mean is of 3, hence [tex]\mu = 3[/tex].
The probability that exactly four road construction projects are currently taking place in this city is P(X = 4), hence:
[tex]P(X = 4) = \frac{e^{-3}3^{4}}{(4)!} = 0.1954[/tex]
0.1954 = 19.54% probability that exactly four road construction projects are currently taking place in this city.

K2 inches -
What is the approximate area of the store in square feet?
O A 2.200
O B. 2,500
OC. 2,300
OD. 2,400
you’ve have by the end of today (12am)
Answer:
B. 2,500
Step-by-step explanation:
The diagram of the area of the store has been divided A and B as shown in the attachment below.
Dimensions of A:
(*Note: scale = 1 in to 16 ft)
Length = 4 inches
Actual length = 4*16 = 64 ft
Width = 1¾ inches
Actual width = 1¾*16 = 28 ft
Area of A = length * width = 64*28 = 1,792 ft²
Dimensions of B:
(*Note: scale = 1 in to 16 ft)
Length = 2¼ inches
Actual length = 2¼*16 = 36 ft
Width = 3 inches - 1¾ inches = 1¼ inches
Actual width = 1¼*16 = 20 ft
Area of A = length * width = 36*20 = 720 ft²
Area of the store = area of A and area of B = 1,792 + 720 = 2,512 ft²
Approximately, the are is 2,500 ft²

gallon for $3.50.
A customer will get
gallons for $7.00.
A customer will get
gallons for $14.00.
A customer will pay $
for 6 gallons.
Answer:
A customer will get 1 gallon for $3.50.
A customer will pay $ 21 for 6 gallons.
A customer will get 4 gallons for $14.00.
A customer will get 2 gallons for $7.00.
Step-by-step explanation:
This is solved using the unitary method .
Four gallons cost $ 14
1 gallon costs $ 14/4= $ 3.5
6 gallons cost = $ $ 14/4 *6= $ 21
2 gallons cost = $ 14/4 *2= $14/2= $ 7
A customer will get 1 gallon for $3.50.
A customer will pay $ 21 for 6 gallons.
A customer will get 4 gallons for $14.00.
A customer will get 2 gallons for $7.00.
This can be found out by using the direct ratio as well.
Gallons Cost

Using cross product
x*4= $ 14*1
x= $ 14/4 = $3.5

Coliform bacteria are distributed in a river at an average concentration of 1 per 20 cc of water. If we draw from the river a test tube containing 10cc of water, what is the probability that the sample contains exactly 2 coliform bacteria
Answer:
0.5
Step-by-step explanation:
Given that: An average concentration of 1 coliform bacteria per 20 cc of the river water.
This implies that in 20 cc of the water, it is certain that 1 coliform bacteria would be found. So that:
pr(1 bacteria in 20 cc of water) = 1
i.e the probability of getting 1 bacteria in 20 cc of water is 1.
The probability of the 10 cc sample of water containing 2 coliform bacteria can be determined as:
pr(2 bacteria in 10 cc of water) = [tex]\frac{1}{2}[/tex]
= 0.5
