probability that a randomly selected
light bulb will last between 750 and 825
hours.

Answer in percentage!!!

Answers

Answer 1
Answer:  34%

This result is approximate.

=========================================================

Explanation:

mu = 750 = mean

sigma = 75 = standard deviation

The raw scores or x values are x = 750 and x = 825

Let's compute the z score for each x value

z = (x - mu)/sigma

z = (750 - 750)/75

z = 0

and

z = (x - mu)/sigma

z = (825 - 750)/75

z = 1

Therefore P(750 ≤ x ≤ 825) is equivalent to P(0 ≤ z ≤ 1) in this context.

Use a z score table to determine that

P(z ≤ 0) = 0.5

P(z ≤ 1) = 0.84314 approximately

So,

P(a ≤ z ≤ b) = P(z ≤ b) - P(z ≤ a)

P(0 ≤ z ≤ 1) = P(z ≤ 1) - P(z ≤ 0)

P(0 ≤ z ≤ 1) = 0.84314 - 0.5

P(0 ≤ z ≤ 1) = 0.34314 approximately

The value 0.34314 then converts to 34.314% which rounds to 34%

Or you could use the empirical rule as shown below. The pink section on the right is marked 34% which is approximate. This pink section is between z = 0 and z = 1.

Answer:

x = 4

Step-by-step explanation:

Use order of operations (PEMDAS) to simplify and solve algebraic equations:

P - Parentheses: Simplify all parentheses in the equation first.
E - Exponents: Evaluate all exponential expressions in the equation next.
M/D - Multiplication/Division: After P and E, Multiplication in the equation comes next. These are interchangeable, so if these are the only operations left, calculate in the direction left to right.
A/S - Addition/Subtraction: After everything else has been done, move on to Addition/Subtraction.  These two are also interchangeable, so you must also calculate in the direction left to right.

First, implement the order of operations to simplify the equation:

2²(x + 3) + 9 - 5 = 32 --- Evaluate the exponent.

4(x + 3) + 9 - 5 = 32 --- Use the Distributive Property to multiply.

4x + 12 + 9 - 5 = 32 --- Add/Subtract (Combine like terms).

4x + 16 = 32

Next, isolate the variable x to solve for its value:

4x + 16 = 32 --- Subtract 16 from both sides of the equation.

4x = 16 --- Divide both sides of the equation by 4 to get the value of x.

x = 4

To confirm that x = 4, you can substitute x for 4 in the original equation and see if both sides of the equation are equal:

2²[(4) + 3] + 9 - 5 = 32 --- Simplify the parentheses.

2²(7) + 9 - 5 = 32 --- Evaluate the exponent.

4(7) + 9 - 5 = 32 --- Multiply.

28 + 9 - 5 = 32 --- Simplify the equation using Addition/Subtraction.

32 = 32

After using substitution, we can confirm that x = 4.

Concept: Solving the Linear Equation

To solve for the x-variable in a linear equation, we will need to isolate it on one side of the equation. If the x-variable is inside a parenthesis, we will need to open the parenthesis first, then isolate the variable. To solve/simplify the equation, we will need to use PEMDAS. It is a common method used to simplify equations and inequalities through priorities.

Concept: PEMDAS

The word "PEMDAS" is a shortened word of "Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction". We follow this order (left-right) to simplify algebraic terms. Since parenthesis is the first priority, we would simplify the expression inside the parentheses. There are two exceptions to this priority in PEMDAS. (1) One of the terms in the expression is a variable, so the expression cannot be simplified, or (2) if there was no parenthesis in the first place. The next priority is "Exponents". This priority is used if there are any exponents used in the equation. The only exception to this priority is when there are no exponents used in the equation. The next priority is "Multiplication". This means that you have to simplify any products "multiplying terms" first. The only exception to this is when there are no terms being multiplied. The next priority is "Division". This priority tells that we need to simplify any division occurring the equation next. There is only one exception to this priority. Only possible if there is no division occurring in the equation. Then, we have "addition" as our 5th priority. This priority states that simplifying any expression that is being added next. The only exception to this priority is when there are no terms being added. The last and final priority is subtraction. This priority states that simplify any expression that is being subtracted. There is no exception to this priority.

Solving for the x variable:

Simplifying the equation using PEMDAS:

We have the following equation: 2²(x + 3) + 9 - 5 = 32

Let us simplify using our first priority. Unfortunately, there is a variable inside the parenthesis. Therefore, we can't simplify the expression inside the parenthesis. Let us now simplify using out second priority. We can see a term outside the parenthesis "2²". Since that term has an exponent, let us simplify that term! Eventually, the term will simplify to 4.

⇒ 4(x + 3) + 9 - 5 = 32

Before we move onto the next priority, let us open the parenthesis as we need to isolate the x-variable. This basically means that we need to simplify the distributive property. To simplify the distributive property, we need to multiply the term outside the parenthesis to all the terms inside the parenthesis. So, we have the following simplified equation:

⇒ 4(x) + 4(3) + 9 - 5 = 32⇒ 4x + 4(3) + 9 - 5 = 32

Our next priority is multiplication. So, let us simplify any products occurring in the equation. We can see 4 being multiplied to 3. Therefore, let us simplify that term! Simplifying that term basically gives us 12. So:

⇒ 4x + 12 + 9 - 5 = 32

Now, our next priority is division. However, we do not see any division occurring in the equation. Therefore, this follows the exception of the division priority in PEMDAS. So, let us move on to the next priority.

The next priority is addition. We can see 12 being added to 9. Therefore, let us simplify the expression. Simplifying that expression gives us 21. So:

⇒ 4x + 21 - 5 = 32

The last and final priority is subtraction. We can see 5 being subtracted from 21. Therefore, let us simplify the expression, which gives us 16. So:

⇒ 4x + 16 = 32

Solving for the x-variable by isolating it:

Now, let us isolate the x-variable to determine its value. This can be done by subtracting 16 on both sides of the equation. Then, we can divide 4 both sides to cancel out the coefficient of x.

⇒ 4x + 16 - 16 = 32 - 16⇒ 4x = 16⇒ 4x/4 = 16/4⇒ x = 4

Therefore, the value of x in the equation is 4.

Special right triangles, such as the one shown, have unique equations that can be used to find missing sides.

The angle measurements show us that this is a 30-60-90 triangle. This name refers to the 3 angle measurement. There are 2 types of special right triangles, 45-45-90 and 30-60-90. For most triangles, it would take the law of sine or cosine to find a missing side with only 1 side given. But, with special right triangles, we can use shortcuts to find a.

Formulas

For all 30-60-90 triangles, there are 3 sides: the hypotenuse (c), the long leg (a), and the short leg (b). The shortcuts for 30-60-90 triangles are based on the length of the short leg.

The formulas are as follows (the variables match the variable given in the figure):

c = 2bb = 0.5ca = b[tex]\sqrt{3}[/tex]

Solving for a

So, to find a, we must first find b. Since b is equal to half of c, we can divide the value of c by 2.

The dimensions of a rectangles are 8cm and 12cm. What is the ratio of its length to its perimeter?

Answers

Answer:

Dimensions = 8 CM and 12 CM

length = 12 CM

width = 8 cm

perimeter = 2 ( length + width)

= 2( 12 + 8)

= 2 ( 20)

= 40 CM

ratio = 12/40

= 6/20

= 3/10

= 3 : 10

solve: √2x-8= √x+4 the equation.​

Answers

Answer:

  (a)  x = 12

Step-by-step explanation:

The radicals in this equation can be eliminated simply by squaring both sides. Then the resulting linear equation is solved in two steps.

__

square

  [tex]\left(\sqrt{2x-8}\right)^2=\left(\sqrt{x+4}\right)^2\\\\2x-8=x+4\qquad\text{simplify}\\\\x-8=4\qquad\text{subtract $x$}\\\\\boxed{x=12}\qquad\text{add 8}[/tex]

Additional comment

You know the contents of each radical must not be negative. That means 2x-8 ≥ 0, or x≥4. We know x=4 doesn't work in the equation (0≠√8), so we only need to check the answers x=12 and x=7. Of those, only x=12 satisfies the equation.

Answer:

They are kind of like outer brackets, so if you have some expression like this:

5 + (4 × 6 + (7 - 8)),

it's better to write it like this:

5 + [4 × 6 + (7 - 8)],

so you can read it more easily.
