Which statement is NOT true?

F. A set of ordered pairs that describes a function cannot have any y-value repeated.

G. A table of values describes a function if all the x-values are different.

H. A mapping is a function if each x-value is paired with exactly one y-value.

J. A graph describes a function if no point on the graph lies directly above or below another of the graph.

Answers

Answer 1
The answer is F. A set of ordered pairs that describes a function cannot have any y-value repeated.

~~

Why??

F - it can be a function even if a y - value repeats itself its the x - values that cannot repeat in order to be a function.

G - this is true as stated above.

H - a mapping is a function if each x - value is paired with only one y - value. If an x - value was paired with multiple y - values then its the same thing as repeated x - values.

J - this is true. To check if a graph is a function try the vertical line test. Simply take a ruler holding it vertically ( up and down ) and place it over a point on the graph. If there is another point lined up with the first one ( above or below ), then it is NOT a function.

I don't quite know how to do this, so if someone could guide me through it that would be nice..!

Answers

The mean of the ages of Doctor 1's patients is 13.54 and the median is 15. The mean of the ages of Doctor 2's patients is 16 and the median is 19.

Explanation:
The mean is found by adding together all of the data points and then dividing by the number of data points. For Doctor 1, (32+20+22+29+15+17+18+1+1+2+3+7+9)/13 = 176/13 = 13.54.

For Doctor 2, (35+20+20+22+23+26+13+17+2+2+3+9)/12 = 192/12 = 16.

The median is the middle number in the data set after it has been ordered from least to greatest. The stem-and-leaf plot organizes it, so we find the middle value.

For Doctor 1, 15 is in the middle.

For Doctor 2, the middle is between 26 and 13: (26+13)/2 = 39/2 = 19.5

Answer:

The mean of the ages of Doctor 1's patients is 13.54 and the median is 15. The mean of the ages of Doctor 2's patients is 16 and the median is 19.

It took Yuik (1/6) of a hour to water get flowers and (4/6) of an hour to weed her garden. What fraction of an hour did Yuik work in her yard

Answers

Yuki worked in her yard for 5/6 of an hour (or 50 minutes). 1/6 + 4/6 = 5/6, because you don’t change the denominator.

The required fraction of an hour is 5/6 Yuik work in her yard.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

It took Yuik (1/6) of an hour to water the flowers and (4/6) of an hour to weed her garden, so in total, she worked for (1/6) + (4/6) = 5/6 of an hour in her yard.

To add the two fractions, we need to have a common denominator, which is 6. Then we can add the numerators (1 + 4) to get 5.

⇒ 5/6

Thus, the final fraction is 5/6.

those are just repeating equivalent decimals
Final answer:

The decimal 0.5 converts to the fraction 1/2 and the decimal 0.7 converts to the fraction 7/10.

Explanation:

To convert the decimal 0.5 and 0.7 into fractions, we use the definition of a decimal. A decimal is a representation of a fraction in terms where we have a power of 10 in the denominator. For instance:

To convert 0.5 into a fraction, we can think of it as 0.5/1 which equals to 5/10 or simplifies to 1/2. Converting 0.7 into a fraction, would give us 0.7/1 which is equal to 7/10.

So, 0.5 as a decimal is 1/2 as a fraction and 0.7 as a decimal is 7/10 as a fraction.

Yes, you're trying to find the volume of paint, but paint is sold in terms of the number of square feet (area) it covers. Rarely do we concern ourselves with computing paint volume from the thickness of the film covering the area.

The rest of the students in the play are from Mr. Logan’s class and Ms. Gardner’s class.
Mr. Logan has 23 students in his class, and 7 of them are in the play. There are 4 more students from Ms. Gardner’s class than from Mrs. Cho’s class in the play.
The number of students in the play from Mr. Logan’s class is greater than the number from Mrs. Cho’s class and fewer than the number from Ms. Gardner’s class.
In all, 30% of the students in these three classes are in the play.

Show or explain why there must be exactly 23 students in Ms. Gardner’s class. As part of the explanation, determine how many students from Ms. Gardner’s class are in the play.

Answers

There should be 23 students from Ms. Gardner’s class in the play.

To determine why there must be exactly 23 students in Ms. Gardner's class and to find out how many students from Ms. Gardner's class are in the play, let's break down the problem step-by-step.

Define Variables:

  - Let L be the number of students in Mr. Logan's class.

  - Let G be the number of students in Ms. Gardner's class.

  - Let C be the number of students in Mrs. Cho's class.

  - Let [tex]P_L[/tex] be the number of students from Mr. Logan's class in the play.

  - Let [tex]P_G[/tex] be the number of students from Ms. Gardner's class in the play.

  - Let [tex]P_C[/tex] be the number of students from Mrs. Cho's class in the play.

Given Information:

  - L = 23

  - [tex]P_L[/tex] = 7

  - There are 4 more students from Ms. Gardner's class in the play than from Mrs. Cho's class: [tex]P_G[/tex] = [tex]P_C[/tex] + 4

[tex]P_G[/tex]

  - The number of students in the play from Mr. Logan's class is greater than the number from Mrs. Cho's class and fewer than the number from Ms. Gardner's class: [tex]P_C[/tex] < 7 < [tex]P_G[/tex]

  - 30% of the students in these three classes are in the play.

Calculate Total Students and Students in the Play:

  - Total students in these three classes: L + G + C

  - Total students in the play: [tex]P_L[/tex] + [tex]P_G[/tex] + [tex]P_C[/tex]

30% of the Students are in the Play:

  - 0.30 (L + G + C) = [tex]P_L[/tex] + [tex]P_G[/tex] + [tex]P_C[/tex]

Substitute L = 23 and [tex]P_L[/tex] = 7:

0.30 (23 + G + C) = 7 + [tex]P_G[/tex] + [tex]P_C[/tex]

Using [tex]P_G[/tex] = [tex]P_C[/tex] + 4 :

0.30 (23 + G + C) = 7 + ([tex]P_C[/tex] + 4) + [tex]P_C[/tex]

0.30 (23 + G + C) = 7 + [tex]P_C[/tex] + 4 + [tex]P_C[/tex]

0.30  (23 + G + C) = 11 + 2[tex]P_C[/tex]

Simplify the equation:

0.30 (23 + G + C) = 11 + 2[tex]P_C[/tex]

0.30 × 23 + 0.30G + 0.30C = 11 + 2[tex]P_C[/tex]

6.9 + 0.30G + 0.30C = 11 + 2[tex]P_C[/tex]

Rearrange the equation:

0.30G + 0.30C = 11 + 2[tex]P_C[/tex] - 6.9

0.30G + 0.30C = 4.1 + 2[tex]P_C[/tex]

Divide by 0.30:

G + C = [tex]\frac{4.1 + 2P_C}{0.30}[/tex]

G + C = [tex]\frac{4.1}{0.30} + \frac{2P_C}{0.30}[/tex]

G + C = [tex]\frac{41}{3} + \frac{20}{3}P_C[/tex]

G + C = [tex]\frac{41 + 20P_C}{3}[/tex]

From the constraints [tex]P_C[/tex] < 7 < [tex]P_G[/tex] and [tex]P_G[/tex] = [tex]P_C[/tex] + 4:

[tex]P_G[/tex] = 7

[tex]P_C[/tex] = [tex]P_G[/tex] - 4 = 7 - 4 = 3

So,

G + C = [tex]\frac{41 + 20 \cdot 3}{3} = \frac{41 + 60}{3} = \frac{101}{3}[/tex]

G + C = 33.67

Since G and C must be integers and they add up to 33.67, we need to check for plausible values of G and C. However, considering our assumptions and given constraints, we should use consistent integer values:

For:

[tex]P_G[/tex] = 7

[tex]P_C[/tex] = 3

Using the total students equation:

0.30(23 + G + C) = 7 + 7 + 3

0.30(23 + G + C) = 17

Thus:

23 + G + C = [tex]\frac{17}{0.30}[/tex]

23 + G + C = 56.67

So:

G + C = 56.67 - 23 = 33.67

Given [tex]P_C[/tex] < 7 < [tex]P_G[/tex], by resolving as integers:

G = 23

C = 11

Thus, Ms. Gardner's class must have 23 students.

A formula is expressed as d=a(2+kt). Express k in terms of d, a and t

Answers

Answer:
k = [tex] \frac{d-2a}{at} = \frac{d}{at} - \frac{2a}{at} = \frac{d}{at} - \frac{2}{t} [/tex]

Explanation:
To get the value of k, we will need to isolate it on one side of the equation.
This can be done as follows:
d = a(2+kt)

1- get rid of the brackets using distributive property:
d = a(2+kt)
d = 2a + akt

2- Subtract 2a from both sides of the equation:
d - 2a = 2a + akt - 2a
d - 2a = akt

3- Divide both sides of the equation by "at":
[tex] \frac{d-2a}{at} = \frac{akt}{at} [/tex] 

[tex] k= \frac{d-2a}{at} [/tex]

4- We can further simplify the answer as follows:
k = [tex] \frac{d-2a}{at} = \frac{d}{at} - \frac{2a}{at} = \frac{d}{at} - \frac{2}{t} [/tex]

Hope this helps :)

Answer:

[tex]k=\frac{d}{ta}-\frac{2}{t}[/tex]

Step-by-step explanation:

d=a(2+kt)

WE need to solve for k. our aim is to get K alone

d= a(2+kt)

To eliminate 'a' we divide by 'a' on both sides

[tex]\frac{d}{a} = 2+ kt[/tex]

To eliminte 2 we subtract 2 on both sides

[tex]\frac{d}{a}-2 =kt[/tex]

Now to isolate K we divide by 't' on both sides

When we divide a fraction by 't' then we multiply 't' at the bottom

[tex]\frac{d}{ta}-\frac{2}{t}=k[/tex]

Answers

Hello there!


The correct answer is option B

Combine like terms

6x + 9 + 3x

9x + 9


I hope this helps!

The expression can be simplified using the distributive property, but it is not in its simplest form, Option A is correct.

What is Expression?

An expression is combination of variables, numbers and operators.

The expression 6x + (9+3x) is in the distributive property.

To see why, we can apply the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. In this case, we have:

6x + (9+3x) = 6x + 9 + 3x

Here, the expression 6x is being distributed over the parentheses, which contain 9 and 3x. We can combine the constants 6x and 9, as well as the like terms 6x and 3x, using the commutative and associative properties of addition:

6x + 9 + 3x

= 6x + 3x + 9

= (6x + 3x) + 9

= 9x + 9

So, the expression can be simplified using the distributive property, but it is not in its simplest form.
