B. Find the value of X. Show your work, I’m not sure how to do this
Answers
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°

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.
Answers
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.
2x+1.5y=30 in slope intercept form
Answers
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

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

the midpoint of the line segment from p 1 p 2 is (- 6, 2) . if p 1 =(-8,2) , what is p 2 ?
Answers
((x1+x2)/2,(y1+y2)/2)
We have the first set of coordinates which is (-8,2) and we have the midpoint which is (-6,2)..
For the x-coordinate:
(-8+x2)/2=-6
-8+x2=-12
x2=-12+8
x2=-4
For the y-coordinate:
(2+y2)/2=2
2+y2=4
y2=2
So the coordinate p2 will be (-4,2)

This equation shows how Rocky the puppy's weight varies with age.

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
Answers
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
