A dog allergy test for people a 98% accuracy rate.Only 1% of the population has an allergy to dogs(actually it is much smaller than that!). Use a group of 100,000 people who’ve taken this test and the information provided to complete a table and answer the following question:
If you tested negative,what is the probability you do not have a dog allergy?
(Express your answer as decimals rounded to four decimal places.)
Answers
Answer:
It is 0.9990
As is 0.0010 as four decimal places. for those that do have which means the same as a negative probability that you don't but reaffirms the situation so inverse of 0.0010 is needed to be 0.9990. so when added together they can become 100% = 1 whole as a probability that both options equal together 1.
When questions ask it negatively using words like don't, haven't, didn't etc. etc.
This question asks for such probability which is similar to percentage in scale for those that do have an allergy.
If the question asked the probability you do have a non allergy the opposite effect happens and we inverse the answer to 99%
But because it asks negatively that you dont have we keep the establishing number of the actual allergy finding because its the same as if you don't.
1% of 100,000 = 1000
1000/100000 = 1/1000
1/1000 = 0.001
Step-by-step explanation:
Once you find 1/1000 is answer to turn numbers into decimals remember the rule 1 = 100
So if 1 = 100
and we want 1/100
1/100 will equal and simplify into 0.01
Where 1/1000 will equal and simplify into 0.001 as the number 100 is extended another digit so would the decimal.

10+10+16.2+16.2+40.5+40.5 = 133.4 cm ^2
Answer:
133.4 cm²
Step-by-step explanation:
The opposite faces of the cuboid are congruent, thus
front/ back = 2(8.1 × 5) = 2 × 40.5 = 81 cm²
top/ bottom = 2(5 × 2) = 2 × 10 = 20 cm²
sides = 2(8.1 × 2) = 2 × 16.2 =32.4 cm²
Thus
Surface area = 81 + 20 + 32.4 = 133.4 cm²

HELP ASAP‼️‼️ A walkway surrounds a rectangular garden. The width of the garden is 5 feet, and the length is 4 feet. The width s of the walkway around the garden is the same on every side. Write an expression that represents the total area of the garden and walkway.
___ s^2+_____s+______
Answers
Answer:
=4x^2 +28x+48
Step-by-step explanation:
Width of the garden is 8
There is walkway on each side of width so add x on each side
With the walkway is x+8+x = 2x+8
Length of the garden is 6
There is walkway on each side of length so add x on each side
With the walkway is x+6+x = 2x+6
The area of the garden is
A = lw
A = 8*6 = 48
The area of the walkway and garden is
A = lw
= (2x+8) (2x+6)
FOIL (first outer inner last)
= 4x^2 + 12x + 16x +48
=4x^2 +28x+48
(a) n is an integer.
−2 < n ≤ 3
List the possible values of n.
Then solve;
Solve 3y − 4 > 17
Answers
The possible integer values of n are:
-1, 0, 1 , 2 , and 3.
-1 to 3 are all greater than -2.
3 is the maximum since 3 is the greatest number where n is equal to it or lesser than it.
Solving the inequality: 3y - 4 > 17
3y - 4 > 17
Add 4 to both sides to move it.
3y > 17 + 4
3y > 21
Divide both sides by 3 to get the value of y.
3y/3 > 21
y > 7
The sign does not change since we did not divide or multiply by a negative.
Therefore, y is greater than 7.

Answer:
(11/20 by 19/40 by 1/40) OR (0.55 by 0.475 by 0.025)
Step-by-step explanation:
To scale down a set of measurements, simply multiply the original measurement by the factors you're scaling it by. For example, take the first measurement of 5 1/2. To scale this down, I turned the value into an improper fraction (11/2) to make the multiplication process easier. Then, I multiplied 11/2 by the factor of 1/10.
After that, I got 11/20, which is the new first measurement.
