You are just find how many fish are salt water and how many freshwater and adding them together. The total number of aquariums is irrelevant in this case.

Answer:

20 x 15 =  A                    A= 300

10 x 6 =  B                      B=60

A + B = F                         F= 360

300 + 60 = F

300 + 60 =360

Answer:

The p value is: 0.0301

Step-by-step explanation:

Given

[tex]\mu = 131520[/tex]

[tex]\bar x = 124247[/tex]

[tex]n = 30[/tex]

Required

Determine the p value

First, calculate the standard deviation of the given data.

This is calculated as:

[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}[/tex]

So, we have:

[tex]\sigma = \sqrt{\frac{(83700 - 124247)^2 + (84380- 124247)^2 + (89380- 124247)^2 + ..... + (156920- 124247)^2 + (168370- 124247)^2}{30}}[/tex]

[tex]\sigma = \sqrt{\frac{13427820070}{30}}[/tex]

[tex]\sigma = \sqrt{447594002.333}[/tex]

[tex]\sigma = 21156[/tex]

The test statistic is then calculated as:

[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]

[tex]t = \frac{124247 - 131520}{21156/\sqrt{30}}[/tex]

[tex]t = \frac{-7273}{21156/5.48}[/tex]

[tex]t = \frac{-7273}{3860.58}[/tex]

[tex]t = -1.88[/tex]

The p value is calculated as:

[tex]P(Z > -1.88)[/tex]

[tex]P(Z>-1.88) = 0.030054[/tex]

[tex]P(Z>-1.88) = 0.0301[/tex] --- approximated.

Hence, the p value is: 0.0301

Step-by-step explanation:

Answer:

the answer is A

A function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that,

$1866 laptop that decreases in value by 20% each year.

Here, f(n)=1866(1+20%)ⁿ, where n is the number of years

f(n)=1866(1+20/100)ⁿ

f(n)=1866(1.2)ⁿ

Therefore, a function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.

Answer:

-24

Step-by-step explanation:

To represent a charge of $24 debited from a bank account, this type of transaction being described as a debit means that a sum of $24 was deducted from the account, meaning the total amount in the account will reduce after this transaction takes place. Hence a charge of $24 being debited will take a negative sign as could be represented by the integer - 24

Answer:

C) C, B, D, E, A, F

Step-by-step explanation:

The closer the data points are to each other along the line of best fit on a scatter plot, the greater the correlation coefficient and vice versa.

Therefore, the scatter plot that has the least correlation coefficient would be the scatter plot with the data points that are farther apart from each other along the line of best fit which is C, followed by B, D, E, A, and F.

I need more information to help you on this question.

Step-by-step explanation:

The points after image reflection in the line x = 2 will be k'(1, 0), L'(4, -4) and J'(3, -1).

In math, graph science is the theory of geometric structures called graphs that are used to represent pairwise different objects. Vertices—also known as nodes or points—that are joined by edges make form a network in this sense.

Undirected graphs, where edges connect two vertices equally, and focused therapy, where edges connect two vertices unevenly, are distinguished.

As per the given information in the question,

Here mirror (x = 2) is vertical, hence only x-coordinate changes vertical distance from x-axis will not change.

For point k(3, 0)

It is one unit right side or x  = 2. So, its  image point will be one unit left side that is k'(1, 0).

For point L(0, -4)

It is two unit left side, so L' will be 2 unit right side of x = 2, so the point will be L'(4, -4)

Similarly, point J(1, -1) will become J'(3, -1).

Answer: Percentage increase: 12.5%

Step-by-step explanation: (EXAMPLE)  percentage increase/decrease = (Vnew - Vold) / Vold × 100%

Example #1

Price percentage increase from old value of $1000 to new value of $1200 is caluclated by:

percentage increase = ($1200 - $1000) / $1000 × 100%

= 0.2 × 100% = 20%

Answer:

12.5%

Step-by-step explanation:

Thank you!

The distance between two coordinate points is 11.66 units.

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].

The given coordinate points are (-3, -2) and (7, 4)

Substitute (x₁, y₁) =(-3, -2) and (x₂, y₂)=(7, 4) in distance formula, we get

Distance = √[(7+3)²+(4+2)²]

= √(100+36)

= √136

= 11.66 units

Therefore, the distance between two coordinate points is 11.66 units.
