A group of 20 students are asked to report the number of pets they keep in their house.
The results are
0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 3, 4, 4, 4, 21

•mean: 2.4 pets
• standard deviation: 4.47 pets
• Q1:0.5 pets
• median: 1 pet
• Q3: 2.5 pets

1. Would any of these values be considered outliers? Explain your reasoning.

2. After being told that they should not count any fish in the report, the value of 3
becomes a 2 and the value of 21 becomes 1. Would these changes affect the median,
mean, standard deviation, or interquartile range? If so, would each measure decrease
or increase from their original values?

Step-by-step explanation:

y-b=m(x-a)

y--8=1/4(x-6)

y+8=1/4(x-6)

4y+32=1(x-6)

4y+32=x-6

4y=x-38

y=1/4x-38/4

or -x+4y+38=0

or -×+4y= -38

Answer:

21

Step-by-step explanation:

The given equation is linear with two variables that will have zero solutions.

A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.

Given equation is x + 2y = 8. The equation is a linear equation with two variables. If the equation will have another equation then the solution will have two values for two variables.

If there is only one equation with two variables we will not get any solution we need one more same equation. The equation will have zero solution.

Therefore, the given equation is linear with two variables that will have zero solutions.

The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

Let y represent the total money the salesman earns for selling a total of $x sales. Hence:

y = 0.085x + 3750

If the salesman makes a total of $138000, hence:

y = 0.085(138000) + 3750

y = 15480

The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.

Answer:

v = 22.5 miles/hour

Step-by-step explanation:

It is given that,

The speed of Penguins is 33 ft/s.

We need to convert the speed to miles per hour.

We know that, 1 mile = 5280 feet

Speed,

[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]

So, the speed of the Penguins is 22.5 miles/hour.

Answer:

3 cm : 1 cm

Step-by-step explanation:

1. 60 : 20

2. divide 10 on both sides = 6 : 2

3. divide by 2 on both sides = 3 : 1

4. 3 cm : 1 cm

I'm so sorry, I just read the ratio is 60 cm to 20 M

So edit:

convert both into a unit, we'll take m.

1 cm = 100 m

so 60 x 100 = 60000 m

= 60000 m : 20 m

= divide by 20 in both sides...

= 3000 m : 1 m

The equivalent expression is: -2x + 10. therefore the correct option is C.

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

From the distributive property;

-2(x - 5)

Then, multiply -2 and -5

-2 * x = -2x

-2 * -5 = 10

because two negatives make a positive

Therefore the answer would be -2x+10.

Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.
