Suppose you choose to keep a jar of readjust on her desk. Currently, the jar includes the following: 17 Pennies 10 Dimes 19 Nickels

starrkingschool.net:

0.0688 = 6.88% probability the you reach into the jar and also randomly grab a nickel and then, without replacement, a penny.

You are watching: What is the modulus of 2+6i

Step-by-step explanation:

A probability is the variety of desired outcomes divided by the number of total outcomes.

Probability of grabbing a nickel:

19 nickels out of 17+10+19+23 = 69 coins, so: Probability that grabbing a penny, considering the an initial coin ordered was a nickel:

17 pennies the end of 68 coins. So What is the probability the you reach right into the jar and randomly take a nickel and then, there is no replacement, a penny? 0.0688 = 6.88% probability the you reach into the jar and randomly seize a nickel and then, there is no replacement, a penny.

Use the WeierstrassM-test to show that every of the following series converges uniformly ~ above the provided domain:
ryzh <129>

starrkingschool.net:

Step-by-step explanation:

Given a collection , the Weierstrass M-test tell us that if we uncover a succession of hopeful numbers such the in a particular domain D, and the series converges, then the collection converges uniformly in the domain D.

So, our target is to uncover the so dubbed sequence . The main idea is to bound the succession of attributes .

Now, an alert that the worths of z are constantly positive, for this reason is constantly positive, for this reason because that all worths of z in . Then, because if us make the worths of the denominator smaller, the whole portion becomes larger.

Moreover, together z is in the term <0,r>, we have that and as an effect . With this in enhancement to the vault bound us obtain With this, our sequence is and the corresponding collection is , i m sorry is a geometric collection with ratio less than 1, hence it is convergent.

Then, as consequence of Weierstrass M-test we have actually the uniform convergence the the series in the offered domain.

By what number must I main point 1 1/4 through to achieve 3/4(fractions)
Reptile <31>
1 1/4x = 3/45/4x = 3/4x = (3/4) / (5/4)x = 3/4 * 4/5x = 12/20 i beg your pardon reduces to 3/5check..1 1/4 * 3/5 =5/4 * 3/5 =15/20 reduces to 3/4 so u would certainly multiply 1 1/4 by 3/5 to get 3/4
