Answer:

Step-by-step explanation:

trust me dude i just took this question :D

The probability of taking out lavender and a rose-perfumed candle with replacement is 0.15 so option (D) will be correct.

Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

Do not take underestimate probability it has several uses in daily life whether forecasts or like that.

Total number of candles = 12 + 8 + 20 = 40

Probability = desire/total

So,

Probability of taking lavender first = number of lavender/total

⇒ 12/40 = 0.3

Now since we again put the lavender into the lot it means all things remain the same.

Probability of rose-perfumed second = number of rose-perfumed /total

⇒ 20/40 = 0.5

Now the probability of A and B is the multiplication of the probability of A and B individually.

So,

The probability of taking out lavender and a rose-perfumed candle

⇒ 03 × 0.5 = 0.15

Hence "The probability of taking out lavender and a rose-perfumed candle with replacement is 0.15".

Answer:

all real values of x

Step-by-step explanation:

khan academy says so

The domain of the parabolic function is all real number. Then the correct option is E.

The domain means all the possible values of x and the range means all the possible values of y.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function is given below.

f(x) = (x + 1)²

Then the domain of the parabolic function is all real number.

Then the correct option is E.

Answer:

Jacob forgot to use the distributive property in the 1st step

Step-by-step explanation:

Jacob should've got 5x+10-7=3x+5 for the 2nd row.

Jacob should be more careful when distributing the numbers, and make sure to distribute into every term inside the parentheses.

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

Given solution is

5(x+2)-7=3x+5

5x+2-7=3x+5

5x-5=3x+5

5x-5+5=3x+5+5

5x=3x+10

5x-3x=3x-3x+10

2x=10

x=5 5[(5)+2]-7=3(5)+5

5(7)-7=3(5)+5

35-7=15+5

28=20

Here we can see that the correct distribution of 5(x+2) would be 5x + 10.

Because Jacob distributed 5 into x correctly and got 5x, however he did not distribute the 5 into 2 properly. It should have been 10.

Jacob should be more careful when distributing the numbers, and make sure to distribute into every term inside the parentheses.

Complete Question

Lacey and Haley are rewriting expressions in an equivalent, simpler form.

a. Haley simplified x³⋅ x² and got

x⁵

Lacey simplified x³ + x² and got the same result! However, their teacher told them that only one simplification is correct. Who simplified correctly and how do you know?

b. Haley simplifies 3⁵⋅ 4⁵ and gets the result 12^10, but Lacey is not sure.

Is Haley correct? Be sure to justify your answer.

Answer:

a) Haley is correct, Lacey simplified wrongly.

b) Haley is incorrect

Step-by-step explanation:

a. Haley simplified x³⋅ x² and got

x⁵

Lacey simplified x³ + x² and got the same result! However, their teacher told them that only one simplification is correct. Who simplified correctly and how do you know?

For Question a, when it comes to simplifying algebraic expression that has to do with powers, there are certain rules that should be followed.

For example

x^a × x^b = x^(a + b)

For Haley, she simplified x³⋅ x² and got

x⁵

She is correct because this follows the product rule of powers or exponents above

= x³⋅ x² = x³+² = x⁵

For Lacey she is wrong because:

x³ + x² ≠ x⁵

x³ + x² when simplified as quadratic equation = x²(x + 1)

b. Haley simplifies 3⁵⋅ 4⁵ and gets the result 12^10, but Lacey is not sure.

Is Haley correct? Be sure to justify your answer.

For question b, when we have two distinct or different numbers with the same power(exponents) the rule states that:

x^a × y^a = (x × y)^a = (xy)^a

Haley is simplified wrongly. She did not apply the rule above

Haley simplified 3⁵⋅ 4⁵ = (3 × 4) ⁵+⁵

= 12^10, this is wrong.

The correct answer according to the rule =

3⁵⋅ 4⁵ = (3 × 4) ⁵ = 12⁵

Therefore,

3⁵⋅ 4⁵ ≠ 12^10

3⁵⋅ 4⁵ = 12⁵

Haley is wrong.

Answer:

n=5

x= 23

p= 4

Step-by-step explanation:

What this wants us to do is find the value of the variable first, then find the measurement of the degrees.

So, for the first equation we need to make an equation.

Since the angles are vertical angles, that means they equal each other.

The equation would be.. 8n=9n-5.

Step 1- Move variable to the left hand side and change its sign

8n-9n= -5

Step 2- Collect like terms

-n= -5

Step 3- Change signs on both sides of the equation

n=5

So, now that we know what the variable is, substitute it into the equations.

8(5)= 40    9(5)-5= 40

For the second equation, the angles equal 180 degrees.

So, that would give us the equation.. 6x+19+x= 180.

Step 1- Add the common variables

(6x+x)+19= 180

7x+19= 180

Step 2- Subtract 19 from both sides.

7x+19= 180

   -19    -19

7x= 161

Step 3- Divide both sides by 7

7x= 161

7     7

x= 23

So, now that we know what the variable is, substitute it into the equations.

6(23)+19= 157

157+23= 180

Finally for the last equation, they are vertical angles, so they equal each other.

So, the equation would be 5p+28= 12p.

Step 1- Move the variable to on side.

5p+28= 12p

-5p         -5p

28= 12-5p

Step 2- Subtract the variables

28= 7p

Step 3- Divide by 7 to both sides.

28= 7p

7     7

p= 4

So, now that we know what the variable is, substitute it into the equations.

5(4)+28= 48

12(4)= 48

Step-by-step explanation:

The given statement is false.

We have the following statement -

Square root of 8 is between 7 and 9.

We have to determine if it is true or false.

Square root of a number is a value, which on multiplication by itself gives the original number.

According to the question -

A = [tex]\sqrt{8}[/tex] = 2.82

Clearly, it is not between 7 and 9.

Therefore, the statement is false.
