GrumpyCorp drug tests all of the recent college graduates it hires each year. The drug test currently used correctly determines drug users 96% of the time(a Positive test) and correctly determines non-users 90% of the time(a Negative test). A recent study concluded that 36% of college students use drugs. A potential employee has been tested and the result was Negative for drug use.
a) Construct ALL necessary probabilities using proper notation(Example: P(D) for a "drug user"). (Hint: there should be 6 total)
b) Find the Probability of a Negative test, by showing use of the above Probabilities first, and then followed by the proper calculation.
c) Use Bayes' Theorem to find the probability that a person who tests Positive actually was not a Drug User. Set up using Conditional Probability Notation and then substitute in numeric values.
Solution :
Drug : Drug user
T : Test positive
a). [tex]P(D) =0.36[/tex]
[tex]$P\left(\frac{T}{D} \right) = 0.96$[/tex]
[tex]$P\left(\frac{T^c}{D^c} \right) = 0.90$[/tex]
b). [tex]$P(T^c)= P\left(\frac{T^c}{D^c}\right) \times P(D^c)+ P\left(\frac{T^c}{D}\right) \times P(D)$[/tex]
[tex]$=0.9 \times (1-0.36) + (1-0.96) \times 0.36$[/tex]
= 0.5904
c). [tex]$P\left(\frac{D^c}{T}\right) = \frac{P\left(\frac{T}{D^c}\right). P(D^c)}{P\left(\frac{T}{D^c}\right). P(D^c) + P\left(\frac{T}{D}\right). P(D)}$[/tex]
[tex]$=\frac{(1-0.90) \times (1-0.36)}{(1-0.90) \times (1-0.36)+(0.96 \times 0.36)}$[/tex]
[tex]$=0.15625$[/tex]
I really don’t get it!!
Answer:
The answer is b.
Step-by-step explanation:
Square root 124, you'll get 29.10, after that once you simplify it, you will get the answer and you will have to do the formula, a^2 + b^2 = c^2 since it is a triangle.
Answer:
x = 11,
m∡LMN = 124°
Step-by-step explanation:
since NO bisects ∡LMN, then ∡LMO = ∡NMO
so we can do the following to solve for 'x':
8x - 26 = 2x + 40
6x = 66
x = 11
now, plug 11 in for 'x' into either expression and double it, since ∡LMN is made up of two equal angles
8(11) - 26 = 88 - 26 = 62
62 x 2 = 124

Question
At 8 a.m., the temperature in a city was -8 degrees Celsius (°C). At noon on the same day, the temperature in
the city was 2°C. What was the difference in temperature, in degrees Celsius, from 8 a.m. to noon in the city?
-6°C
2°C
4°C
10°C
Answer: 10°C
Step-by-step explanation:
[tex]-8-2=\\-10\\|-10|=10[/tex]
The difference in temperature, in degrees Celsius, from 8 a.m. to noon in the city is, 10°C
We have to give that,
At 8 a.m., the temperature in the city was -8 degrees Celsius (°C). At noon on the same day, the temperature in the city was 2°C.
Hence, the difference in temperature, in degrees Celsius, from 8 a.m. to noon in the city is,
d = |- 8 - 2|
d = |- 10|
d = 10
So, Option d; 10° C is correct.

What is Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle.
Given that, a scenario that is making an arrangement of a right-angled triangle, we need to find the base, [refer to the figure attached]
So, here we will use the Pythagoras theorem
75²+base² = 96²
base² = 96²-75²
base = √3591
base = 59.92
Hence, the distance between them is 59.92 ft

3. Find the surface area of the cylinder. (1 point)
2009.6 in
401.9 in
803.8 in
602.9 in
Answer:
Option (3)
Step-by-step explanation:
Surface area of a cylinder is given by the formula,
Surface area = 2πr(r + h)
Here, r = radius of the circular surfaces
h = Height of the cylinder
From the figure attached,
r = 8 in.
h = 8 in.
Therefore, Surface area of the cylinder = 2π(8)(8 + 8)
= 256π
= 803.8 in² [If π = 3.14]
Option (3) will be the correct option.
An automobile manufacturer claims that its car has a 37.2 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this car since it is believed that the car has an incorrect manufacturer's MPG rating. After testing 120 cars, they found a mean MPG of 37.1. Assume the standard deviation is known to be 1.1. A level of significance of 0.05 will be used. Make a decision to reject or fail to reject the null hypothesis.
Answer:
fail to reject the null hypothesis
Step-by-step explanation:
Based on the information provided I would fail to reject the null hypothesis. This is because the Miles per gallon that the independent testing firm has concluded for the car nearly matches the car's MPG claim. The difference being 0.1 . Since the standard deviation is 1.1 for this test, this means that the average falls perfectly within this range and makes the data very compelling. Combine this with a very low level of significance, I would say that the claim is backed by the data.

Write the ratio as a fraction in lowest terms. Be sure to make necessary conversions:
12 feet to 15 inches
48/53
Steps
15 inches = 1.25 feet
Ratio = 12 : 1.25
Simplified = 9.6 : 1
9.6 + 1 = 10.6
9.6/10.6 = 48/53
Checking...
12 feet = 144 inches
Ratio = 144 : 15
144 + 15 = 159
