Answer:

the rational ones are the ones that are gonna give you an equal answer and the irrational the opposite.

Step-by-step explanation:

2a +2c= 5a - 5b

collect light terms.

take 2a on the other side

2c = 5a -2a-5b

2c = 3a - 5b

divide 2c's 2 on both sides

and

c = (3a - 5b)/2

Answer:

Answer is explained below.

Step-by-step explanation:

a)

Adding control group will definitely benefit the study, as it will behave as the reference, or a benchmark for comparison. In order to compare and study the effects of the treatment control group is the one to compare with. So, in this way study would benefit by adding the control group, as it will become easier to know how much effective is the treatment as compared to the control group.

b)

Now, we have to randomly place the gerbils into the 1. Antibiotic A 2. Antibiotic B, and 3. control Groups

So, we have 3 groups to place gerbils randomly.

Now, we have to find the no. of replicates needed for 3 groups and 300 Gerbils.

n = t x r

n = 300

t = 3

r = ?

r = n/t

r = 300/3

r = 100 replicates will be needed.

First of all, we need to find the total number of experimental plots = n = 300

Secondly, we need to give each experimental plot a plot number in consecutive manner for example: we have 300 experimental plots

We can give numbers as 1,2,3,4,5 ...... 300

Thirdly, we need to give treatments a experimental plot picked from the random number table. For that, 300 divided  by 3 = 100  numbers are to be achieved and put them in ascending or descending order.

c)

The best blocking method would be the blocking by breed of Gerbils. As in zoo, we know that, gerbils can develop gastrointestinal tract issues as they get older that may cause severe diarrhea and dehydration. But on the contrary, it gets better when it get old in case of breed of gerbils. Hence, the best blocking method would be the blocking by breed of gerbils instead by zoo.

Answer:

1680 in^3

Step-by-step explanation:

SO you got the triangle

24*10=240

240/2=120

now we just need to find the area

There is a formula but I think this is easier

So theres a rectangle with a length of 14

So if you think of the triangle as the base, you just need 14 triangles stacked up to make up the volume

So 120*14=1680

So the volume is 1680

Answer:

y = -4/3x + 20

Step-by-step explanation:

2x + 1.5y = 30

1.5y = 30 - 2x

y = 20 - 4/3x

y = -4/3x + 20

Answer:

Step-by-step explanation:

2x + 1.5 y = 30

1.5 y = -2 x + 30

y = 2/3 (-2x + 30 )

y = -4/3 x + 20

Where m = -4 /3 and b = 20

Step-by-step explanation:

Answer:

63°

Step-by-step explanation:

The sum of all interior angles of a triangle = 180°

Therefore:

x + 96° + 21° = 180°

x + 117 = 180

Subtract 117 from each side

x = 180 - 117

x = 63°

Step-by-step explanation:

-5x + 6y = 12

y = 5/6x + 2

-5x + 6y = 12

-5x + 6(5/6x + 2) = 12

-5x + 5x + 12 = 12

x real numbers

(x, y) = (x, 2 + 5/6 x)

Answer:

The graph cannot represent a proportional relationship

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form. In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin (0,0) . That means, ----> The x-intercept and the y-intercept of the line must to be the origin (0,0).

If the given line passes through the point (0,5), then the line does not pass through the origin. Therefore, the graph cannot represent a proportional relationship

Answer:

D. (2, 1)

Step-by-step explanation:

Given:

y = 6x - 11

-2x - 3y = -7

Required:

Find the solution.

Solution:

y = 6x - 11 ---› eqn. 1

-2x - 3y = -7 ----› eqn 2

Substitute y = (6x - 11) into equation 2.

-2x - 3(6x - 11) = -7

-2x - 18x + 33 = -7

-20x + 33 = -7

Subtract 33 from each side

-20x = -7 - 33

-20x = -40

Divide both sides by -20

x = -40/-20

x = 2

Substitute x = 2 into equation 1.

y = 6x - 11 ---› eqn. 1

y = 6(2) - 11

y = 12 - 11

y = 1

The solution is very (2, 1)

Answer:

The fourth term of given geometric sequence is 5/9

Step-by-step explanation:

The general formula for geometric sequence is given by:

[tex]a_n = a_1.r^{(n-1)}[/tex]

Here a_n is the nth term,

a_1 is the first term

and r is the common ratio.

It is given in the question that

[tex]a_1 = 15\\r = \frac{1}{3}[/tex]

Putting these values

[tex]a_n = 15 . (\frac{1}{3})^{n-1}[/tex]

For 4th term, we will put n=4

So,

[tex]a_4 = 15 . (\frac{1}{3})^{4-1}\\a_4 = 15 . (\frac{1}{3})^3\\a_4 = 15 . \frac{1}{27}\\a_4 = \frac{15}{27}\\a_4 = \frac{5}{9}[/tex]

Hence,

The fourth term of given geometric sequence is 5/9

Answer:

Age of Rocky = 5 months

Step-by-step explanation:

Given that:

Equation for calculating puppy's weight

p = 3a + 2

Here,

p = weight of puppy

a = age in months

We have to find the age if the weight is 17 pounds

Putting p=17 in given equation

17 = 3a + 2

17 - 2 = 3a

3a = 15

Dividing both sides by 3

[tex]\frac{3a}{3}=\frac{15}{3}\\a=5[/tex]

Hence,

Age of Rocky = 5 months
