Select the statement that is known to be true.
ser-zykov [4K]

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

Carlos and his family left for the amusement park at 8:35 Ask Your Teacher The trip took 1 hour 55 minutes. What time did they a
My name is Ann [436]

Answer:Carlos and his family arrived at 10:30

Step-by-step explanation:

The time Carlos and his family left for the amusement park =8:35

Since The trip took 1 hour 55 minutes., we have to add it to the time they left for  the amusement park to now the time they arrived

 8: 35  =8 hrs   35minutes

            <u> 1 hr      55 minutes</u>

<u>                            90  minutes </u>

but 90minues is greater than 60 so we convert to hours and minutres by dividing by 60 giving us

90/60=1.5hrs=1hr 30mins

8¹ hrs   35minutes

<u> 1 hr      55 minutes</u>

<u>  10hrs  30  minutes </u>

Therefore, They arrived at 10:30

Find the measure of each acute angle in a right triangle where the measure of one acute angle is 3 times the sum of the measure
luda_lava [24]
A right triangle has 1 90 degree angle and the interior angles must add to 180.

3(x+8)+x+90=180
3x+24+x+90=180
4x+114=180
4x=66
x= 16.5

Plug this value in to find the last angle
16.5+90+x=180
106.5+x=180
x=73.5

Final answer: 73.5 degrees and 16.5 degrees
