Answer:
[tex](x-5)(x+1)(x-2)[/tex]
Step-by-step explanation:
well as a general case we have
when we say that
[tex]x=y[/tex] it gives zero moving the y to the other side we have
[tex]x-y=0[/tex]
so in our case
[tex]\longrightarrow x-5=0\\\\\rightarrow x-(-1)=0\\\\\longrightarrow x+1=0\\\\\longrightarrow x-2=0[/tex]
just multiply the ones that have [tex]\longrightarrow[/tex]
and get
[tex](x-5)(x+1)(x-2)=0[/tex]

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°

2x+1.5y=30 in slope intercept form
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

What is the solution to the following system densations?
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)
Gerbils can develop gastrointestinal tract issues as they get older that may cause severe diarrhea and dehydration. A researcher wishes to conduct a study to find which of two antibiotics, Antibiotic A or Antibiotic B, is more effective in improving gastrointestinal tract health. A total of 300 Gerbils that are at least 1 years old will be randomly selected from zoos in the state of Florida. The researcher will get consent from all owners, treat the gerbils for ten months and evaluate changes in gastrointestinal health.
Part A: How would the study benefit from adding a control group?
Part B: What is the best way to randomly place the gerbils into the Antibiotic A, Antibiotic B, and control groups?
Part C: The researcher wants to use a blocking variable to place gerbils into groups instead of doing it randomly. He decides to block either by breed or zoo. Explain which would be the best blocking method.
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.

Question 1 of 10 What is the value of the fourth term in a geometric sequence for which ay = 15 and r= 1/3? Express your answer as a fraction. Answer here
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:
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

2. 12.1
3. 23.1
4. 96.8
Answer:
3.2
Step-by-step explanation:
divide 5.5 from both sides
x = 17.6/5.5 = 3.2
Find x where 2/3 of x added to 9 gives 30
This equation shows how Rocky the puppy's weight varies with age.
p = 3a + 2
The variable a represents Rocky's age in months, and the variable p represents Rocky's
weight if pounds. At how many months did Rocky weigh 17 pounds?
O months
Submit
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

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
