Answer:

5a + 15

Step-by-step explanation:

To simplify, simply distribute 5 to all terms within the parenthesis. Multiply in this case:

5(a + 3):

5 * a = 5a

5 * 3 = 15

5a + 15 is your answer.

Answer:

30% probability that the ball taken from B is red.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Red ball from urn A:

3/6 = 1/2 probability of getting a red ball from urn A.

Then urn B will have 5 balls, 2 of which are red, so 2/5 probability of getting a red ball.

Blue ball from urn A:

3/6 = 1/2 probability of getting a blue ball from urn A.

Then urn B will have 5 balls, 1 of which is red, so 1/5 probability of getting a red ball.

Total:

[tex]p = \frac{1}{2}*\frac{2}{5} + \frac{1}{2}*\frac{1}{5} = \frac{2}{10} + \frac{1}{10} = \frac{3}{10}[/tex]

3/10 = 0.3 = 30%.

30% probability that the ball taken from B is red.

Answer:

r = 20

Explanation:

-4 = r/20 - 5

-4 = r/20 - 5

-4 = 1/20r + -5

-4 = 1/20r - 5

1/20r - 5 = -4

1/20r - 5 + 5 = -4 + 5

1/20r = 1

(20)1/20r = 1(20)

~While adding , the sign of each term of second expression remains same. So, Remove the unnecessary parentheses :

⤑ [tex] \tt{3 {a}^{2} + 2ab + 2b + 5 {a}^{2} - 3ab + 9}[/tex]

~Like terms are those which have the same base. Combine the like terms :

Answer:

Simplified answer is: [tex]8a^2 - ab + 2b + 9[/tex]

Step-by-step explanation:

Key skills needed for understanding: Combining Like Terms

1) You are given the equation: [tex](3a^{2} + 2ab + 2b) + (5a^{2} - 3ab + 9)[/tex]

- Since you are adding here, you can remove the parentheses.

- If you remove them it would be --> [tex]3a^2 + 2ab + 2b + 5a^2 - 3ab + 9[/tex]

2) Now we have to combine like terms in order to simplify this equation.

Combining like terms is simply combining terms with the same base (such as the terms that have "ab" or the terms that have "[tex]a^2[/tex]" or the terms that have nothing  - these terms are numbers such as 9 or 5).

You can combine 2ab and -3ab, but you cannot combine 9 and 2b. Hope you understood this concept.

3) If you combine like terms ( [tex]3a^2 + 5a^2[/tex], [tex]2ab - 3ab[/tex]) you will get a different expression: [tex]8a^2 - ab + 2b + 9[/tex].

[tex]8a^2 - ab + 2b + 9[/tex] is the answer.

Hope you understood and have a nice day!! :D

Answer:

x = 31

Step-by-step explanation:

Given:

MN = 20

PQ = x

RS = 42

Required:

Value of x

SOLUTION:

In a trapezoid, the midsegment length equals the sum of both bases divided by 2

This implies that:

PQ = ½(MN + RS)

Plug in the values

x = ½(20 + 42)

x = ½(62)

x = 31

false

Step-by-step explanation:

the perimeter is all the sides added up whereas the area is length × width

area is measured in square units not perimeter

The perimeter does not measures in square units because area should be measured.

A perimeter refers to the closed path that encompasses or outlines and represents the two-dimensional shape or a one-dimensional length. The perimeter of a circle is known its circumference.

Therefore, we can say that the The perimeter does not measures in square units because area should be measured.

hence, it is false.

Step-by-step explanation:

Remark

They are alternate interior angles and therefore equal.

Solution

8x - 10 = 3x + 90              Subtract 3x from both sides

8x - 3x - 10 = 90               Combine the left

5x - 10 = 90                      Add 10 to both sides

5x = 90 + 10

5x = 100                           Divide by 5

x = 20      

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

That isn't the answer. You need 3x + 90

The question is incomplete. Here is the complete question.

A cell phone company is interested in the relationship between the number of texts per minute for their customers (y) and customer age. Based on the data collected, the least-squares regression line is [tex]y=3.27+2.14x[/tex], where x is the number of years by which age exceeds 12. Which of the following statements best describes the meaning of the slope of the least-squares regression line?

a. For each increase in age of 1 year, the estimated number of texts per minute increases by 3.27.

b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.

c. For each increase of one text per minute, there is an estimated increase in age of 3.27 years.

d. For each increase of one text per minute, there is an estimated increase in age of 2.14 years.

e. The slope has no meaning because the units of measure for x and y are not the same.

Answer: b. For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.

Step-by-step explanation: The least-squares regression is a method of fitness, i.e., it fits a data set of number into an equation.

In this case, the relationship between number of texts per minute and customer age is given by a line equation:

[tex]y=3.27+2.14x[/tex]

in which, y represents the number of texts per minute and x is the age.

In a line equation, slope is the measure of steepness, i.e., how inclined the line is.

In the least squares regression line, slope is 2.14 and it means, in each additional year, the number of texts increase by a factor of 2.14, which is the correct alternative.

Unit vector along the direction v = <3,1,-4> is :

[tex]\hat{v} = \dfrac{3i + j -4k}{\sqrt{3^2 + 1^2 + 4^2}}\\\\\hat{v} = \dfrac{3i + j -4k}{5.1}[/tex]

So, unit vector opposing the [tex]\hat{v}[/tex] is :

[tex]\hat{v'} = -\hat{v}\\\\\hat{v'} = -( \dfrac{3i + j -4k}{5.1})\\\\\hat{v'} = \dfrac{-3i - j +4k}{5.1}[/tex]

so, vector of magnitude 3 units in opposite direction from v is :

[tex]\vec{V} = 3\hat{v'}\\\\\vec{V} = \dfrac{3}{5.1}( -3i -j+4k)[/tex]

Hence, this is the required solution.

Answer:

Find out  the selling price.

To prove

As given

A store manager instructs his employees to mark up all the items by 25%. An item that the store bought for $16.

25% is written in the decimal form.

= 0.25

25% of the $16= 0.25 × 16

                         = $4

Selling price of the item = Original price of item + 25% of the $16

                                       = $16 + $4

                                      = $ 20

Therefore the selling price of the item is $20.

A. What is the total amount to be paid at the time of the purchase?

This will be the selling price of the stereo with the tax and the deferral. This will be:

= $1052.75 + $40

= $1092.75

B) What is the amount of each monthly payment?

Each monthly payment will be gotten by dividing the total payment to be made by 12. This will be:

= $1092.75 / 12

= $91.06
