Lets look at the chart, and see how similar each value is:
At 11, there is:
Both have 1 point. THis is similar
At 12:
Both have 1 point. This is similar
At 13:
One has 1 point, the other has 2 points. This is not similar
Next we have 14:
Both have 2 points. This is similar
15:
Both have 4 points. THis is similar
16:
Both have 3 points. This is similar
17:
One has 2 points the other has 1 point. This is not similar
So, 5 out of the 7 poitns are similar
And remember, the two points that are not similar are only off by 1.
So I would conclude that they are highly similar.
Hope this helps!

Describe the set of all positive integers from 10 to 15 using the descriptive method
Given:
The set of all positive integers from 10 to 15.
To find:
The given set by using the descriptive method.
Solution:
The positive integers are 1, 2, 3, 4,... .
The positive integers from 10 to 15 are 10, 11, 12, 13, 14, 15.
So, the given set has 5 elements 10, 11, 12, 13, 14, 15.
Using the descriptive method, the given set is defined as "The set of all positive integers greater than or equal to 10 and less than or equal to 15".
Therefore, the set of all positive integers greater than or equal to 10 and less than or equal to 15.
A new test is developed to test for organic matter in soil samples, giving "positive" or "negative" results to indicate that a sample does or does not contain organic matter.
For a soil sample that contains organic matter, the test will give a positive result 95% of the time and a negative result (false negative) 5% of the time. For a soil sample that does not contain organic matter, the test will give a positive result (false positive) 20% of the time and a negative result 80% of the time.
A study included a population of 1,000 soil samples, and 70% of those studied where known to contain organic matter.
Fill in the missing values in the table and statement below. If necessary, round the percentage to one decimal place.
Number of
Samples Positive
Result Negative
Result

Organic Matter 700 665
Does Not Contain
Organic Matter 300
240
If a soil sample test gives a positive result, it is
% likely that the soil sample contains organic matter.
Answer:
35
60
91%
Step-by-step explanation:
If a soil sample test gives a positive result, it is **91.7%** likely that the soil sample contains organic matter.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Positive results= 95%
Negative results= 5%
Now,
Positive result = 700 * 0.95 = 665
Negative result = 700 * 0.05 = 35
Similarly, for the soil samples that do not contain organic matter, we know that 20% of them will give a positive result and 80% will give a negative result. So, we can multiply 300 by 0.2 and 0.8 to get:
Positive result = 300 * 0.2 = 60
Negative result = 300 * 0.8 = 240
To fill in the missing value in the statement, we can use Bayes' theorem, which states that:
P(A|B) = P(B|A) * P(A) / P(B)
So, we have:
P(contains organic matter | positive result) = P(positive result | contains organic matter) * P(contains organic matter) / P(positive result)
P(positive result) = P(positive result | contains organic matter) * P(contains organic matter) + P(positive result | does not contain organic matter) * P(does not contain organic matter)
P(positive result) = 0.95 * 0.7 + 0.2 * 0.3
P(positive result) = 0.665 + 0.06
P(positive result) = 0.725
Plugging these values into Bayes' theorem, we get:
P(contains organic matter | positive result) = (0.95 * 0.7) / (0.725)
P(contains organic matter | positive result) = (0.665) / (0.725)
P(contains organic matter | positive result) = 0.9172
Therefore, by probability the answer will be 91.7%

Answer:
C. The scale factor is less than one.
Step-by-step explanation:
By definition, similar triangles have equal angles and proportional corresponding side lengths. Thus, A, B, and D are all mutually exclusive, leaving C the only possible answer. Upon further inspection, the scale factor is indeed greater than one (each side length is scaled by a factor of two, which is large than one)
You randomly draw a marble from a bag, record is color, and then replace it. You draw a blue marble 11 out of 50 times. What is the experimental probability that the nes marble will be blue? Write your answer as a fraction, de mal, or percent. The experimental probabilty that the next marble will be blue is
Explanation:
This may seem like a trick question, but it's not. Your teacher simply wants to know how many times you got blue out of the number of times total. The numerator is the number of blue. The denominator is the number of total tries. The fraction 11/50 cannot be reduced because 11 and 50 share no common factors other than 1.
Notes:
11/50 = 0.22 = 22%The answer above applies to experimental probability only. The theoretical probability is likely different. We don't have enough info to compute the theoretical probability.State the x- and y-intercepts of each equation

Answer:

Step-by-step explanation:
I believe that this is correct because 220 is divisible by 5, which means it has completed the pattern 44 times (220 divided by 5 is 44). So 221 means that it has completed it 44 times, and then starts it one more time with only the first number.

What is the vertex of the function f(x) = x2 + 12x?
O (-6, -36)
O (-6,0)
O (60)
O (6,-36)
Answer:
es la tercera amiga yo pienso
The vertex of the function f(x) = x² + 12x is,
⇒ Vertex = (- 6, - 36)
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x) = x² + 12x
Now, We can change the function into the form,
f (x) = (x - h)² + k
Where, (h, k) is vertex.
Here, The function is,
⇒ f (x) = x² + 12x
⇒ f (x) = x² + 12x + 36 - 36
⇒ f (x) = (x + 6)² - 36
⇒ f (x) = (x - (- 6))² + (- 36)
Hence, By comparing,
Vertex = (h, k) = (- 6, - 36)
Thus, The vertex of the function f(x) = x² + 12x is,
⇒ Vertex = (- 6, - 36)

Hello! I really need some help on this.
Answer:
The area is 51 units squared.
Step-by-step explanation:
Since you are finding the area of a triangle, you first start with 12 x 8.5 = 102.
Then, you divide 102 in half, since the shape is a triangle. So, 102 ÷ 2 = 51.
So the answer is 51 units squared.
