Answer:

8(w+6)=9

You must add parentheses to show the order in which you will complete the problem. Because it says “eight times the sum of a number and 6” you have to find the sum first, then multiply 8.

Answer:

the term is separated by minus (-) and plus (+) .

therefore this term is trinomial.

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.

Answer:

1/3 would be the chances you'd pick purple, because there's only 1 in 3 that's purple out of all 3 marbles.

With green it would be 2/3 because there's twice the number of green marbles than purple.

If there's 1 of purple and 1 of green, the probability would then be 1/2 of picking either colour.

Answer:

C: A randomized block design experiment

Step-by-step explanation:

We are told the participants are divided by gender into groups which we can call blocks. Then, within each group, they are randomly assigned to either the treatment or control group. This means they are assigned treatments within each block.

A randomized block design is defined as an experimental design whereby the experimental units are divided into groups which we call blocks. After that treatments will be randomly assigned to the experimental units within each of the blocks.

Thus, this corresponds with our question and we can say it's a randomized block design experiment.

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.

Hope that helps.

Answer:

2 solutions

Step-by-step explanation:

Given the expression

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

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

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]

The (r and h ) is the radius and height of the cylinder and [tex]s(r)= \frac{12}{r}[/tex]represent the region of the mark in this r and h, and that is why  as can's radius gets bigger and larger, the label area gets closer to 0.

Answer:

A cylindrical can needs to have a volume of 6 cubic inches. A label is to go around the

side of the can. The function gives the area of the label in square inches

4 divided by 3C

If C equals 6, then the equation now looks like 4 divided by 3(6).

3 x 6 = 18.

4 divided by 18 is .22 repeating.

This may be wrong. Check with another answer.

Answer: 2/9

Work: So, you are going to get the equation after plugging in the number 4/3(6), after simplifying even more, you get 4/18. Then you simplify again and divide both sides (Numerator and denominator) and you get 2/9.
