b)
a)
Write the amount of boys in the class as a fraction in its simplest form.
b)
Write the amount of girls in the class as a fraction in its simplest form.

Answers

Answer:

Boys: 1/3

Girls: 2/3

Step-by-step explanation:

There are 8 boys in the class out of 24 students.

The fraction will be 8/24. Both the numerator and the denominator are divisible by 8.

8 ÷ 8 = 1

24 ÷ 8 = 3

The simplest form will be 1/3.

There are 16 girls in the class because 24 - 8 = 16.

The fraction will be 16/24. Both numbers are divisible by 8.

16 ÷ 8 = 2

24 ÷ 8 = 3

The simplest form will be 2/3.

Answers

Answer:

D. StartRoot 3 EndRoot x + 3 y = 0   (or √3x + 3y = 0)

Step-by-step explanation:

This is about converting polar coordinate to rectangular

Relationship between coordinates is:

x = r cosθy = r sinθ

then

y/x = sinθ/cosθy/x = tanθ

We have θ = 5π/6, finding the value of tan:

tan 5π/6 = tan (π - π/6) = - 1/√3 = - √3/3

First term: 2 3/4 sixth term: 3 7/12 what is the rule

Answers

Answer:

we conclude that the rule will be:

[tex]a_n=\frac{31}{12}+\frac{1}{6}n[/tex]

Step-by-step explanation:

Given

[tex]a_6=3\frac{7}{12}=\frac{43}{12}[/tex]

[tex]a_1=2\frac{3}{4}=\frac{11}{4}[/tex]

We know the arithmetic sequence with the common difference is defined as

[tex]a_n=a_1+\left(n-1\right)d[/tex]

where a₁ is the first term and d is a common difference.

so

a₆ = a₁ + (6-1) d

substituting a₆ = 43/12 and a₁ = 11/4 to determine d

[tex]\frac{43}{12}=\:\frac{11}{4}\:+\:5d[/tex]

switch sides

[tex]\frac{11}{4}+5d=\frac{43}{12}[/tex]

subtract 11/4 from both sides

[tex]\frac{11}{4}+5d-\frac{11}{4}=\frac{43}{12}-\frac{11}{4}[/tex]

[tex]5d=\frac{5}{6}[/tex]

Divide both sides by 5

[tex]\frac{5d}{5}=\frac{\frac{5}{6}}{5}[/tex]

[tex]d=\frac{1}{6}[/tex]

as

a₁ = 11/4

[tex]d=\frac{1}{6}[/tex]

Therefore, the nth term of the Arithmetic sequence will be:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting d = 1/6 and a₁ = 11/4

[tex]a_n=\frac{11}{4}+\left(n-1\right)\frac{1}{6}[/tex]

    [tex]=\frac{11}{4}+\frac{1}{6}n-\frac{1}{6}[/tex]

    [tex]=\frac{31}{12}+\frac{1}{6}n[/tex]

Therefore, we conclude that the rule will be:

[tex]a_n=\frac{31}{12}+\frac{1}{6}n[/tex]

X=number of hours

Y=6,7,8,9,10,11,12,13,14

What is the slope? What does it represent?

Answers

Answer:

[tex]Slope = 1[/tex]

It represents: The number of tents made in an hour

Step-by-step explanation:

Given

X=0,1,2,3,4,5,6,7,8

Y=6,7,8,9,10,11,12,13,14

Required

Determine the slope

The slope is calculated as:

[tex]Slope = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Pick any two corresponding values of x and y

[tex](x_1,y_1) = (0,6)[/tex]

[tex](x_1,y_1) = (8,14)[/tex]

[tex]Slope = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]Slope = \frac{14 - 6}{8 - 0}[/tex]

[tex]Slope = \frac{8}{8}[/tex]

[tex]Slope = 1[/tex]

It represents: The number of tents made in an hour

Joelle wants to place an oversized image which is 30.51 cm wide so that it appears centered on the page. The width of the page is 21.59 cm. In the program, horizontal positions to the right of the leftmost edge of the page are positive. What horizontal position for the left edge of the image should Joelle use to center the image?

Answers

-4.46cm

Step-by-step explanation:

The horizontal midpoint of the page is;

The horizontal midpoint of the image is given as;

For the image to be centered, these to midpoints must be on the same point in the axis.

If we take the leftmost edge of the paper to be point zero on the axis, then, the distance accommodated by the paper is 10.795cm.  The distance that goes beyond this leftmost edge is computed as;

On the axis, this is on the negative side. Therefore, the horizontal position for the left edge of the image that Joelle should use to center the image is -4.46cm.

If an independent-measures design is being used to compare two treatment conditions, then how many different groups of participants would be needed and how many scores would there be for each participant

Answers

Answer:

2 groups and 1 score for each participant

Step-by-step explanation:

An independent measures design is a defined as a research method whereby multiple experimental groups are examined and the participants will only be in one group. Now, each participant will only be affected by one condition of the independent variable during the experiment.

In the question given, we want to use the method I just described to compare two treatment conditions.

This means that there will be two groups and each participant in both groups will be assigned one score.

Which expressions are equivalent to 6a(5+d) ?

SELECT EACH CORRECT ANSWER (theres more than 1)

30a+6ad
(6a⋅5)+(6a⋅d)
11a + d
30a+(6a⋅d)
30ad

Answers

Answer:

first, second and fourth

Step-by-step explanation:

If you use distribution,

6a(5+d) is the same as  

6a(5) + 6a(d)

Multiplied =  30a + 6ad

So it's the 1st 2nd and fourth choice.

1st is stated above when multiplied out and combined.

2nd is after distribution.

4th choice is basically combination of 1 and 2 where one is combined (first term) and the second one just set up to be multiplied.

It cannot be third because you are multiplying the factors and not adding so you cannot have 11a.

It cannot be last choice because you have different types of terms that cannot be combined (one with a alone and one with ad)

Answer:

(6a*5) + (6a*d)

30a + 6ad

30a + (6a*d)

Find the LCM of the expression at the left hand side:

2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1

open the bracket

4m²-6m-4m²-6m/(4m²-9) = 1

Cross multiply

4m²-6m-4m²-6m = 4m²  - 9

-12m = 4m²  - 9

4m²  - 9+12m = 0

4m² +12m-9 = 0

Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2

Equality PropertiesSolving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

a + 4b = -4

a + 10b = -16

Step 2: Rewrite Systems

a + 4b = -4

Subtract 4b on both sides:          a = -4 - 4b

a = -4 - 4b

a + 10b = -16

Step 4: Solve for b
