What proportion of a normal distribution is located between z = 1.00 and z = 1.50?
lesya692 [45]

Answer:

0.092 is the required proportion.

Step-by-step explanation:

We are given the following in the question:

A normal distribution.

We have to find the proportion of data lying between z = 1.00 and z = 1.50.

P(between z = 1.00 and z = 1.50)

P(.001 \leq z \leq 1.50)\\= P(z \leq 1.50) - P(z < 1.00)\\= 0.933 - 0.841 = 0.092 = 9.2\%

Thus, 0.092 is the proportion of data located between z = 1.00 and z = 1.50.

A chess tournament was being held. This single-elimination tournament (in which paired competitors
Sergeeva-Olga [200]

Answer:

A total of 15 matches were played.

Step-by-step explanation:

To determine the number of matches that were played in the chess tournament, knowing that there are 16 participants who face each other in a tournament of direct elimination, the following logical reasoning must be carried out:

In the first round there are 16 players, so being matches between 2 players, there are 8 matches (16/2). In the second round, applying the same reasoning and taking into account that there are only 8 players left, since the others have been eliminated, there are 4 matches (8/2). The same in the semifinals, where there are 2 games (4/2), and finally, the final to a single game.

Therefore, since 8 + 4 + 2 + 1 equals 15, the number of matches played in the tournament is 15.

Write the additive and multiplicative inverse of -1/2​
stellarik [79]

Answers:

Additive Inverse = 1/2

Multiplicative Inverse = -2

========================================

Explanation:

The additive inverse of x is -x. The two add to 0.

So the additive inverse of -1/2 is 1/2 because -1/2+1/2 = 0.

--------------

The multiplicative inverse of x is 1/x

More thoroughly, the multiplicative inverse of a/b is b/a.

We apply the reciprocal operation here.

That means the multiplicative inverse of -1/2 is -2/1 which simplifies to -2.

We can see that (-1/2)*(-2) = 1

Any nonzero value multiplied with its multiplicative inverse will always result in 1.
