Answer:
any number equal or greater than 1
Step-by-step explanation:
5 time what is bigger the 4
1. 12 feet = 144 inches
15 feet = 180 inches
144 inches / 8 inches = 18
180 inches / 10 inches = 18
The scale factor was 18.
2. Volume = Length x Width X height:
Volume = 16 x 13 x 11 = 2,288 cubic inches.
Answer:
-8/5 = -1.6 (the smallest number here)
-5/8 = -0.625
your answer is A :)
Answer:
There is approximately 17% chance of a person not having a disease if he or she has tested positive.
Step-by-step explanation:
Denote the events as follows:
<em>D</em> = a person has contracted the disease.
+ = a person tests positive
- = a person tests negative
The information provided is:
Compute the missing probabilities as follows:
The Bayes' theorem states that the conditional probability of an event, say <em>A</em> provided that another event <em>B</em> has already occurred is:
Compute the probability that a random selected person does not have the infection if he or she has tested positive as follows:
So, there is approximately 17% chance of a person not having a disease if he or she has tested positive.
As the false negative rate of the test is 1%, this probability is not unusual considering the huge number of test done.

7 - 4x = 7y
4x + 7y = -7
The parallel through (2,0) keeps the coefficients on x and y and just changes the constant:
4x + 7y = 4(2)+7(0)= 8
7y = -4x + 8
y = (-4/7) x + 8/7
Choice B
