The answer to the question
Answer:
1
Step-by-step explanation:
Calculation steps:
-7-(-8) = ⇒ two negatives cancel and change to positive
- 7 + 8 = ⇒ 8-7 = 1
1 ⇒ answer
Answer:
16 cookies
Explanation:
If each box has 32 cookies then, 4•32=128
Then if Leslie divides them equally into 8 platters, 128/8 will equal 16.
Answer:
c) there is an efficient algorithm to test whether an integer is prime
Step-by-step explanation:
The basis of modern cryptography is the fact that factoring large numbers is computationally difficult. No algorithm is efficient for that purpose.
<h3>Choices</h3><h3>a)</h3>
False - there is no known efficient algorithm for factoring large numbers
<h3>b)</h3>
False - there are 78,498 prime numbers less than 1,000,000. That is about 8% of them--far from being "most of the integers."
<h3>c) </h3>
True - a variety of algorithms exist for testing primality. In 2002, a test was published that runs in time roughly proportional to the 7.5 power of the logarithm of the number being tested.
<h3>d)</h3>
False - there is no known efficient algorithm for factoring large numbers
Considering that the data is only noted and not changed, this is an example of an observational study.
<h3>What are observational and experimental studies?</h3>
- Experimental study: In an experimental study, there is an intervention in a sample, and it's effect is studied.
- Observational study: In an observational study, the sample is just analyzed, without any intervention.
In this problem, the data, which is the number of miles traveled, is only analyzed, no interventions are made, hence this is an example of an observational study.
