The probability of getting a negative result is 0.175 or 17.5%.
To calculate the probability of getting a negative result, we need to consider the sensitivity and specificity of the diagnostic test.
Given that the prevalence of the condition is 12.5%, we can assume that 12.5% of the population has the condition, and the remaining 87.5% does not.
The sensitivity of the test is 80%, which means that it correctly identifies 80% of the individuals with the condition as positive.
The specificity of the test is 95%, which means that it correctly identifies 95% of the individuals without the condition as negative.
To calculate the probability of getting a negative result, we need to consider both the true negative rate (1 - sensitivity) and the proportion of individuals without the condition (1 - prevalence).
Probability of getting a negative result = (1 - sensitivity) × (1 - prevalence)
= (1 - 0.80) × (1 - 0.125)
= 0.20 * 0.875
= 0.175
Therefore, the probability of getting a negative result is 0.175 or 17.5%.

Find the probability that a number selected at random from the numbers 1 to 25 is not a prime
number when each of the given numbers is equally likely to be selected.
#no irrelevant answer
Answer:
Favourable outcomes = {1,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25}
Number of favourable outcomes=16
Number of total possible outcomes=25
p(not a prime) = (number of favourable outcomes) / number of total possible outcomes
=16/25
Required Sample space of the following event ( Non- prime numbers between 1 to 25 )
\(\dashrightarrow\) 1, 4, 6, 8,9 10,12, 14, 15, 16,18, 20, 21, 22, 24, 25
Number of Favourable Outcomes = 16
Total number of outcomes = 25
Now as we know
Probability of an event =
\(\star\;\boxed{\sf{\pink{\dfrac{ Favourable\; number\;of\; outcomes}{Total\; number\;of\; outcomes}}}}\)
Probability = 16/25
Hence, probability that the number is not a prime number is 16/25.

1. Determine the value of \( n \) so that the average rate of change of the function \( f(x)=x^{2}-3 x+7 \) on the interval \( -5 \leq x \leq n \) is \( -1 \). [4]
To determine the value of \( n \) such that the average rate of change of the function \( f(x) = x^2 - 3x + 7 \) on the interval \( -5 \leq x \leq n \) is \( -1 \), we need to find the average rate of change of the function and set it equal to \( -1 \). By using the formula for the average rate of change, \(\frac{{f(b) - f(a)}}{{b - a}}\), where \( a \) is the starting point of the interval and \( b \) is the ending point, we can set up the equation and solve for \( n \).
The average rate of change of a function on an interval is defined as the difference in the function values divided by the difference in the corresponding input values. In this case, we have the function \( f(x) = x^2 - 3x + 7 \) and the interval \( -5 \leq x \leq n \).
To find the average rate of change, we use the formula: \(\frac{{f(b) - f(a)}}{{b - a}}\), where \( a \) is the starting point of the interval and \( b \) is the ending point. In this case, \( a = -5 \) and \( b = n \).
We want the average rate of change to be \( -1 \), so we set up the equation: \(\frac{{f(n) - f(-5)}}{{n - (-5)}} = -1\). Substituting the function \( f(x) = x^2 - 3x + 7 \) and solving for \( n \), we can determine the value of \( n \) that satisfies the given condition.

Let A={(x-3)/(x-2)ЄR : X<0}
be a subset of real numbers.
i) Define A's supremum and infimum.
The supremum of the set A does not exist (it is negative infinity), and the infimum of the set A is 1.
To define the supremum and infimum of the set A, we first need to determine the properties of the set.
The set A is defined as A = {(x-3)/(x-2) ∈ R : x < 0}.
To find the supremum (also known as the least upper bound) of A, we need to find the smallest value that is greater than or equal to all the elements of A. In other words, we are looking for the least upper bound of the set A.
Let's analyze the elements of A:
For x < 0, the expression (x-3)/(x-2) can take on different values depending on the value of x. We need to find the maximum value that this expression can reach for all x < 0.
As x approaches 0 from the left side, (x-3)/(x-2) approaches negative infinity. Therefore, there is no finite supremum for the set A.
Next, let's find the infimum (also known as the greatest lower bound) of A. We need to find the largest value that is less than or equal to all the elements of A. In other words, we are looking for the greatest lower bound of the set A.
Again, analyzing the elements of A:
As x approaches negative infinity, (x-3)/(x-2) approaches 1. Therefore, the infimum of the set A is 1.

Find A and B if the graph of Ax + By = 12 passes through (2, 1) and is parallel to the
graph of 2x − 7y = 3.
Answer:
A is -8
B is 28
Step-by-step explanation:
Let us rewrite the equation in the standard format of y = mx + b
By = -Ax + 12
y = (-A/B)x + 12/B
Now, since the line is parallel to the line given below, then their slopes must be equal
2x - 7y = 3
7y = 2x - 3
y = (2/7)x - 3/7
slope here is 2/7
Thus;
-A/B = 2/7
let’s now insert the point that the line passes through
We have;
1 = (-A/B)2 + 12/B
but -A/B = 2/7
1 = 4/7 + 12/B
12/B = 1 - 4/7
12/B = 3/7
B = (7 * 12)/3
B = 28
-A/28 = 2/7
-7A = 56
A = 56/-7
A = -8

Step-by-step explanation:
Each of the following is a strategy for generating a hypothesis, EXCEPT:
A) introspection.
B) finding the exception to the rule.
C) thinking of things unilaterally.
D) thinking about variables in terms of amount or degrees.
The strategy for generating a hypothesis that does not fit among the options provided is option C) Thinking of things unilaterally.
Introspection, finding exceptions to the rule, and thinking about variables in terms of amount or degrees are all valid strategies for generating hypotheses.
Introspection involves reflecting on personal experiences, thoughts, and observations to generate hypotheses about a particular phenomenon or question.
Finding exceptions to the rule involves identifying instances that do not conform to the expected pattern or generalization, which can lead to the formulation of alternative hypotheses.
Thinking about variables in terms of amount or degrees involves considering how varying levels or quantities of a particular variable may impact the outcome or relationship being studied, which can help generate hypotheses about the nature and direction of the relationship.
On the other hand, "thinking of things unilaterally" is not a recognized strategy for generating hypotheses. The term "unilaterally" typically refers to actions or decisions made by one side or party without considering others.
Hypothesis generation involves considering multiple perspectives, factors, and possibilities, rather than approaching it unilaterally.The correct answer is option c.

No, milliliters (mL) and centiliters (cl) are not the same units of measurement. They are both units of volume, but with different scales.
Is a ml the same as a cl?
A milliliter (mL) is a unit of volume in the metric system, equal to one-thousandth of a liter (1 mL = 0.001 L). Milliliters are commonly used to measure the volume of liquids, such as medicine or cooking ingredients.
A centiliter (cl) is also a unit of volume, and it is equal to one hundredth of a liter (1 cl = 0.01 L). Centiliters are less commonly used than milliliters and are generally used in the same contexts where milliliters are used.
In conclusion, mL and cl are different units of volume and cannot be used interchangeably. Milliliters are smaller units than centiliters, so when converting between the two, a conversion factor of 10 must be used. For example, 1 cl = 10 mL.

Answer:
I believe its C- 25%
Step-by-step explanation:
If you count how far it is from 15 to 20 (5) and divide that by 1/20 you should end up with 0.25. Turn that into a percent and you get 25%.
Let me know if Im wrong!
The percentage of the time will Oliver arrive between 15 and 20 minutes late to work is 25%. The correct option is 3.
What is density curve?A probability density function, also known as the density of a continuous random variable in probability theory, is a function whose value at any given sample in the sample space can be interpreted as providing a relative likelihood that the random variable's value will be equal to that sample.
The total area under the uniform density curve between 10 and 30 is equal to 1, which represents 100% of the time.
To find the percentage of the time that Oliver arrives between 15 and 20 minutes late, we need to find the area of the uniform density curve between 15 and 20 and then convert it to a percentage.
The width of the uniform density curve between 15 and 20 is 5 units (20 - 15 = 5), and the height is 1/20. Therefore, the area of this region is:
Area = width x height = 5 x (1/20) = 1/4
To convert this to a percentage, we multiply by 100:
Percentage = (Area/Total area) x 100% = (1/4) x 100% = 25%
Therefore, the answer is 25%.

if you borrow $500 for 4 years at an annual interest rate of 6 years how much will you pay altogether
The amount will be after 4 years at interest rate of 6%, $624.76
To calculate the total amount you will pay after borrowing $500 for 4 years at an annual interest rate of 6%, you can use the formula for compound interest:
A = P x (1 + r/n)^(nt)
where:
A is the total amount,
P is the principal amount (the initial amount borrowed),
r is the annual interest rate as a decimal,
n is the number of times interest is compounded per year,
t is the number of years the money is borrowed for.
In this case, P = $500, r = 6%, n = 1 and t = 4.
So, the formula becomes:
A = $500 x (1 + 0.06/1)^(1 x 4)
A = $500 x (1.06)⁴
A = $500 x 1.249536
A = $624.76
Therefore, you will pay a total of $624.76 after borrowing $500 for 4 years at an annual interest rate of 6%.

Using the critical values of t=+/-2.201 is less likely to lead to rejection of the null hypothesis than using the critical values of +/-2.093.
Critical Value Definition -
Critical value can be defined as a value that is compared to a test statistic in hypothesis testing to determine whether the null hypothesis is to be rejected or not.
If the value of the test statistic is less extreme than the critical value, then the null hypothesis cannot be rejected.
Critical values are essentially cut-off values that define regions where the test statistic is unlikely to lie; for example, a region where the critical value is exceeded with probability \alpha if the null hypothesis is true.
Using the critical values of t=±2.201 is more "conservative" than using the critical value of ±2.093 because it is more likely to reject the null hypothesis using the greater value i-e t=±2.201.
