when you take everything out of the sq rt, [tex]\sqrt{81/625}[/tex] turns into 9/25, and x^2 and Y^2 turn into simply x and y. Then you multiply. 25xy times 9/25xy. 25 cancels out and both y and x are squared and you're left with 9x^2y^2

A certain component is critical to the operation of an electrical system and must be replaced immediately upon failure. If the mean lifetime of this type of component is 100 hours and its standard deviation is 30 hours, how many of these components must be in stock so that the probability that the system is in continual operation for the next 2000 hours is at least 0.95?
Answer:
Step-by-step explanation:
From the given information:
Assuming we have an integer c to represent the components in the stocks.
Thus, the needed probability can be expressed as:
[tex]P(X_1+X_2+ ........ X_c \ge 2000)[/tex]
To break this down, we have:
[tex]P(\sum X_i \ge 2000) = P \Bigg(\dfrac{\sum X_i - 100n}{\sqrt{n \ Var (X)}} \ge \dfrac{2000-100 n }{\sqrt{n \times 900}} \Bigg )[/tex]
[tex]P \Bigg(\dfrac{\sum X_i - 100n}{\sqrt{n \ Var (X)}} \ge \dfrac{2000-100 n }{\sqrt{n \times 900}} \Bigg )= P (Z \ge 0.95 ) \ \ \ because \ Z_{0.05} = -1.65 \\ \\ \\ \dfrac{2000-100 n }{\sqrt{n \times 900}} = -1.65 \\ \\ \\ \dfrac{100\ n-2000 }{\sqrt{900n}} = 1.65 \\ \\ 100 n -1.65 \sqrt{900 n }-2000 = 0[/tex]
By solving the equation:
n = 23
Thus, relating to the needed condition; n ≥ 23
The needed number of the components that should be in stock should be at least 23.

Answer:
SA = 112 cm²Steps:
to solve this problem we have to calculate the surface area of the whole block and let be SA
first the surface area of the square pyramid:
the area of one triangle = (height × base)/2
given:
height = 6 cm
base = 4 cm
A = (6×4)/2
A = 24/2
A = 12 cm²
since it's a square triangle
then the surface area of the pyramid excluding the base:
Ap = A × 4
Ap = 12 × 4
Ap = 48 cm²
now the inferior part which is a rectangular prisme
Ar = 4(height×lenght)+lenght²
Ar = 4(3×4)+4²
Ar = 4×12+16
Ar = 48+16
Ar = 64 cm²
and now we can calculate the surface area of the whole block
SA = Ap + Ar
SA = 48 + 64
SA = 112 cm²
Find the area of the rectangle measurement below 5/4 km x 12/5 km
Answer:

Define expression.Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
[tex]=(6t^{2} -8bs) (t^{2} + bs)[/tex]
[tex]=6t^{2} (t^{2} + bs) -8bs(t^{2} + bs)[/tex]

How many combinations with repetition are allowed if n = 8 and r = 4?
256

1,680
65,536
The combinations with repetition are allowed is 330
What is combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items, where the order of the items is not fixed.
Given that, we need to find the number of combinations with repetition are allowed if n = 8 and r = 4
Combinations with repetition = C'(n, r) = (r+n-1)! / (r!(n-1)!)
= (8+4-1)! / 4!(8-1)!
= 11! / 4!7!
= 330
Hence, the combinations with repetition are allowed is 330

Can you use the values in Pascal’s triangle to find the powers of 11? Explain.
Answer: Yes!
-Ultimately (it states) all numbers in existence can be extracted from Pascal's Triangle. Using his binomial formation of: (a + b)^0 = 1 , where y is the number you are using. and (a + b)^x is the equation you use to find the answer of that row... the usage of that row, and the formation of its components is how you find the powers of numbers in a given row
-You would be able to find each row of the Triangle, and by using the association of Multiplication, addition, distribution, and If you look at the images below you will notice that to find a power of 11 at it's 6th power, you look at the 6th row of Pascal's Triangle Although not completely relevant, I also added an image of using his Triangle to find the Powers of 2

Manuel will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $60 and costs an additional $0.60 per mile driven
The second plan has no initial fee but costs $0.80 per mile driven.
For what amount of driving do the two plans cost the
same?
miles
What is the cost when the two plans cost the same?
3
From the given values and conditions, We need to form a equations and equate both sides to solve for the miles, The answer is 300 miles.
What is a equation?An equation is a statement of equality between two expressions. It typically includes numbers and mathematical operations such as addition, subtraction, multiplication, and division. For example, the equation 2x + 3 = 7 is a statement that the value of the expression 2x + 3 is equal to the value of 7. Equations can also include variables, which represent unknown values that can be solved for.
What is unitary method?The unitary method is a method used in mathematics to solve problems involving units of measurement. It involves expressing the units of measurement as a fraction or multiple of a single unit and then using this fraction or multiple to solve the problem. The method is particularly useful in solving problems involving conversions between different units of measurement. The unitary method is particularly useful in solving word problems where the conversion of units is required. It involves expressing the given information in terms of a single unit and then using that information to find the unknown quantity.

-13a = 20
a = -20/13
Let's check
7 - 13(-20/13) = 27
7 + 260/13 = 27
