D. $14

Answer:

No it's not a function

Step-by-step explanation:

Every point line up evenly when it's vertical. just take your pencil and put it on the circle vertically and you will see that the points will line up

So it's not. function

pls mark brainiest because i didn't waste your time lol

Answer:

no

Step-by-step explanation:

the answer is no because each value in the domain is associated with exactly one point in the codomain, but a line passing though the circle generally intersects the circle at two points

Independent Variable:  Jazz music

Dependent Variable: Sleeping Time

Experimental Group: people sleeping with jazz music

Control Group: people sleeping without jazz music

3 constants:

No of people in group

Jazz music

Sleep

Step-by-step explanation:

The independent variable is the one which is not altered by any outer influence. For example the jazz music will not be interrupted by the sleeping habits of people.

The dependent variable is the one which is affected by external changes such as sleeping time is afffected by external music or noises.

Experimental group on which experiment is being carried out.

Control group is which determines the changes in experimental group.

Constants which do not change for the number of experiment, could be number of people, type of jazz music, volume of jazz music also sleep is a constant .

Answer:

Try writing to your teacher, why students should have game time on Fridays.

Step-by-step explanation:

Children at school are getting worried about recent events, but letting kids play Video games will keep their minds more focus on the game, instead of their worries. Plus this can give teachers extra time to plan lessons or just take a relaxing break, teachers deserve it anyways.

speed =  [tex]\frac{distance}{time}[/tex]

speed = [tex]\frac{100}{2.5}[/tex]

speed = 40 feet per second

Answer:

Question 1 answer: the two angles are the same.

Question 2 answer: The value of the angles is 76.

Question 3 answer: The value of the angle is 36.

Question 4 answer: all angles in the figures are classified as acute angles

Step-by-step explanation:

First all of, using one of the triangle rules, both the angles are congruent. Then, because both 1 and 2 are the same and the triangle in 1 already have the other two angles, use 180 - 85 - 19 and get 76. Lastly moving on to the other triangle, same method, 180 - 76 -68 and get 36. Because all these angles are less than 90 degrees and anything less than 90 is considered to be acute.

D.

subtracting the smallest value of the lower half of the data set from the biggest value of the lowest half of the data set

The lower quartile of a set of data is calculated by subtracting the smallest value of the lower half of the data set from the biggest value of the lowest half of the data set.

"A quartile is a statistical term that describes a division of observations into four defined intervals based on the values of the data and how they compare to the entire set of observations.

Just like the median divides the data into half so that 50% of the measurement lies below the median and 50% lies above it, the quartile breaks down the data into quarters so that 25% of the measurements are less than the lower quartile, 50% are less than the median, and 75% are less than the upper quartile."

From the definition it is clear that,

lower quartile of a set of data is calculated by :

subtracting the smallest value of the lower half of the data set from the biggest value of the lowest half of the data set.

Hence, D is the correct option.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The amount after the transaction.

= Amount in account - Amount withdrawn + Amount deposited

The account balance after the transaction is $160.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3 + 4 + 4 - 3 is an expression.

3x + 4 = 5 - 3 is an expression.

We have,

Amount at the account when open = $80

Amount withdrawn = $35

Amount deposited = $115

The amount after the transaction.

= Amount in account - Amount withdrawn + Amount deposited

= 80 - 35 + 115

= $160

Thus,

The account balance after the transaction is $160.

Answer:

10 families have cats

25 families have dogs

Step-by-step explanation:

The difference of ratio units is 5-2 = 3. The difference in pet counts is 15, so we can see that each ratio unit stands for 15/3 = 5 pets. Then ...

 dogs : cats = 5 : 2 = (5·5) : (2·5) = 25 : 10

There are 10 families with cats and 25 families with dogs.

Step-by-step explanation:

Parallel lines have equal slopes.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

L₁ is y = 5x + 1 ← in slope- intercept form

with slope m = 5

L₂ is 2y - 10x + 3 = 0 ( subtract - 10x + 3 from both sides )

2y = 10x - 3 ( divide all terms by 2 )

y = 5x - [tex]\frac{3}{2}[/tex] ← in slope- intercept form

with slope m = 5

Since L₁ and L₂ have equal slopes then they are parallel lines

Step-by-step explanation:

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, 5) into the partial equation

5 = 6 + c ⇒ c = 5 - 6 = - 1

y = 2x - 1 ← equation of line
