Answer:

You are right!

Step-by-step explanation:

I'll go through why the others aren't right.

B:  BD/XY do not correspond to the similar sides of the two.  BC would need to be over WX and XY would need to be under CD

C:  The second proportion is reversed, you need to keep the shape that has its side in the numerator in the numerator and the one in the denominator int he denominator.

D:  Same as B.  You don't need to actually answer me, but maybe you can tell which sides correspond to those written.

Also let me know if you need any further explanation.

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

How do you solve this? [question in attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

In order to find the perimeter of a shape, we should add all of its sides.

Since a triangle has only 3 sides, we add 3 sides together, like so:-

      ⇒ 9x-7+12x-13+3x+8

Combine like terms:-

    ➪ 9x+12x+3x-7-13-8

Which simplifies to

     ➪9x+15x-7-21

On further simplification,

➪24x-28

So we conclude that the perimeter of the triangle is 24x-28 units.

<h3 /><h3>Good luck.</h3>

Kaylis [27]

The probabilities can be calculated using an online calculator or tables, depending on which is more readily available.

QUESTION A

P(Z>1.48)

Using calculators, the probability will be:

P(Z\gt1.48)=0.069

QUESTION B

P(Z\leq1.94)

Using calculators, the probability will be:

P(Z\leq1.94)=0.974

QUESTION C

P(-0.76Using calculators, the probability will be:[tex]P(-0.76\lt Z\lt2.05)=0.756
