If from a population of 50 bank accounts, we want to take a random sample of four accounts in order to learn about the population. The number of different random samples of four accounts that are possible is 230,300.
How to find the different random samples?Given data:
Number of population of bank account = 50
Random sample = 4 accounts
Now let find the different random samples of four account that are possible
Different random sample = 50! / (50 -4)! × 4!
Different random sample = 50! / 46! × 4!
Different random sample = 230,300
Therefore the different random samples is 230,300.

What is linear equation ?A straight line equation and equations with a maximum order of one are referred to as "linear equations." The formula for the linear equation can be written as Y = mx + b, where m is the slope of the line, b is the y-intercept, and x and y are the variables. Slopes tell us the direction and steepness of a line. The value of y when x is 0 is referred to as the y-intercept because (0,y) is the point where the line crosses the y-axis.
CalculationLet's say the number of calls on the second night was x.
The first evening was then x+7.
The third evening she received 4x calls.
Add them up to make 109 calls....
x + x+7 + 4x = 109
6x + 7 = 109
6x = 102
x = 17 calls
x+7 = 24 calls
4x = 68 calls

For isosceles triangle RST the measure of angle T is 34 degree
In this question, we have been given a isosceles triangle RST with RS = RT.
So, by isosceles triangle theorem,
angle S = angle T
So, angle T = (3x - 2)°
We know that the sum of all angles of triangle is 180°
∠R + ∠S + ∠T = 180°
9x + 4 + 3x - 2 + 3x - 2 = 180°
15x + 4 - 4 = 180°
15x = 180°
x = 12
So, 3x - 2 = 3(12) - 2
= 34°
Therefore, for triangle RST the measure of angle T is 34 degree

The probability that the fish is at most 0.5 meters away from the center of the container, considering the volume of the cube, is given as follows:
0.0723 = 7.23%.
What is the volume of a cube?The volume of a cube of side length s is given by the side length cubed, that is:
V = s³.
The cube in this problem has a side length of 1.2 meters, hence the volume is given as follows:
V = 1.2³ = 1.728 cubic meters.
Considering only the inner 0.5 meters of the cube, the volume is given as follows:
V = 0.5³ = 0.125 cubic meters.
A probability is given by the division of the number of desired outcomes by the number of total outcomes, hence:
p = 0.125/1.728 = 0.0723 = 7.23%.

Answer:
D
Step-by-step explanation:
Rewrite as equivalent rational expressions with denominator (5c+9)(c−3)(c−8): 8/5c^2-6c-27, 2c/5c^2-31c-72
The equivalent rational expression with the same denominator as given will be 8(c - 8)/[(c - 3)(5c - 9)(c - 8)] and 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)].
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
As per the given expression,
8/(5c² - 6c - 27) , 2c/(5c² - 31c - 72)
Now, take the first denominator,
5c² - 6c - 27 = 5c² - 15c + 9c - 27
⇒ 5c(c - 3) - 9(c - 3)
⇒ (c - 3)(5c - 9)
Take the second denominator
5c² - 31c - 72 = 5c² - 40c + 9c - 72
⇒ 5c(c - 8) + 9(c - 8)
⇒ (c - 8)(5c + 9)
Therefore, the expression converts as,
8/[(c - 3)(5c - 9)] , 2c/[(c - 8)(5c + 9)]
8/[(c - 3)(5c - 9)] = 8(c - 8)/[(c - 3)(5c - 9)(c - 8)]
2c/[(c - 8)(5c + 9)] = 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)]
The denomiantor of both expression are same.
Hence "The equivalent rational expression with the same denominator as given will be 8(c - 8)/[(c - 3)(5c - 9)(c - 8)] and 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)]".

The seal's new position relative to the surface of the ocean is 47 meters below.
How to calculate the value?It is important to note that that question has to do with elevation which is the change in position with regards to the sea or ocean level.
In this case, the harbour seal dives 35 metres below the ocean's surface and then it dives down an additional 12 metres

Answer:

Step-by-step explanation:
The angles are equal to each other. Set them equal and solve for x
5x + 18 = 8x - 12 Subtract 5x from both sides of the equation
18 = 3x - 12 Add 12 to both sides of the equation
30 = 3x Divide both sides by 3
10 = x
Now that you have found x plug is back into 5x + 18
5(10) + 18
50 + 18 = 68
Answer:
∠ FLJ = 68°
Step-by-step explanation:
∠ EKG and ∠ FLJ are alternate exterior angles and are congruent , then
8x - 12 = 5x + 18 ( subtract 5x from both sides )
3x - 12 = 18 ( add 12 to both sides )
3x = 30 ( divide both sides by 3 )
x = 10
Then
∠ FLJ = 5x + 18 = 5(10) + 18 = 50 + 18 = 68°
