Has condition Does not have condition totals
Test positive
Test negative
Totals
What is the probability (as a percentage) that a person has the condition if he or she tests positive? (Round your answer to one decimal place.)
Solution:
Population in the city= 10,000
As genetic condition affects 8% of the population.
8 % of 10,000
As, it is also given that, there is an error rate of 1% for condition (i.e., 1% false negatives and 1% false positives).
So, 1% false negatives means out of 800 tested who are found affected , means there are chances that 1% who was found affected are not affected at all.
So, 1% of 800
Also, 1% false positives means out of 10,000 tested,[10,000-800= 9200] who are found not affected , means there are chances that 1% who was found not affected can be affected also.
So, 1% of 9200
1. Has condition Does not have condition totals = 800
2. Test positive =92
3. Test negative =8
4. Total =800 +92 +8=900
5. Probability (as a percentage) that a person has the condition if he or she tests positive= As 8% are found positive among 10,000 means 9200 are not found affected.But there are chances that out of 9200 , 1% may be affected
that is Probability equal to 0.01 or 1%.
b. What is x equal to if Scura produces and sells 45000 bottles of sunblock?
Answer:
a) 50,000 bottles
b) x = 45
Step-by-step explanation:
We are given the following in the question:
The annual revenue of sun block depends on how much they sell.
Let x be the quantity of 5 oz. bottles of sun block that they make and sell each year measured in 1000 's of bottles.
For x = 10,
10,000 bottles were made and sell each year.
For x = 25,
25,000 bottles of sun block were made and sell each year.
a) x = 50
Thus, 50,000 bottles of sun block does Scura make and sell.
b) Scura produces and sells 45000 bottles of sunblock
We have to find the value of x
Thus, x = 45 if Scura produces and sells 45000 bottles of sunblock.
Length of a curve is the length of its plot its curve. The length of the given curve for given range of t is: L = 1.44 units approx.
If the curve has position vector p(x) for value of x ranging from x = a to x = b,
then, the curve's length is calculated as:
units.
For the given case, we have:
Position vector =
Its differentiation gives:
Its non negative magnitude is: ||R'(t)|| =
Thus, as t ranges from a = 0 to b = 1, thus, length of the curve is:
Thus,
The length of the given curve for given range of t is: L = 1.44 units approx.

now taking the differentiation
now taking the modulus
=
now taking the integration
length of the curve =
now put the value v= 4 + 9t²
dv= 18 tdt
now put this value in the above equation
we get
length of the curve =
now taking integation we get and put the value of the v
we get
= × ×
=
now find out the length of the curve in the interval from 0 to 1.
length of the curve
Hence proved
Answer is lots of god Which equation is the inverse of y = 100 – x2?




An equation is created when two expressions are separated by an equal sign.
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
Given, A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is utilized. Based on the degree, there are three different sorts of equations. Equations that are linear, quadratic, and cubic.
Therefore, The statement formed when an equal sign is placed between two expressions is called an equation.
