H=(...-2,-10,1,2,...3what type of set is H

e-lub [12.9K]

Answer: Universal set

Step-by-step explanation:

A universal set is usually represented by U and it is set that has all the elements of a related sets.

For example, if there are two sets which are X and Y. Let's say X = {1,2,3} and Y = {1,a,b,c}, therefore, the universal set will be U = {1,2,3,a,b,c}.

In the above scenario, H(...-2,-10,1,2,...3) is a Universal set.

Suppose two dice (one red, one green) are rolled. Consider the following events. A: the red die shows 1; B: the numbers add to 4

kirill115 [55]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given by

Event A: the red die shows 1

Event B : the numbers add to 4

Event C: at least one of the numbers is 3

Event D : the numbers do not add to 9.

D' means the number add to 9.

We need to write the following statement in symbolic form:

Either the numbers add to 9 or the red die shows a 1.

So, it becomes,

$D'\cup A$

Number of elements in D'∪A = 1.

Hence, Third option is correct.

What is the measure of angle x?

arsen [322]

Answer:

x° = 83°

Step-by-step explanation:

All angles in a triangle (any kind of triangle: right, isosceles, equilateral etc.) add up to 180 degrees.

So, if we are given the ABC triangle, then:

angle A + angle B + angle C = 180°

In this particular case, we are given values of two angles, so using the previous relation, we can write:

x° + 44° + 53° = 180°

Now, it's easy to find x°:

x° = 180° - 44° - 53°

x° = 83°

mihalych1998 [28]

Answer:

5 minutes.

Step-by-step explanation:

We have been given that a bank finds that the average number of people waiting in line during lunch hour is 10. On average, during this period, 2 people per minute leave the bank after receiving service.

We will use flow time formula to solve our given problem.

$\text{Flow time}=\frac{\text{Number of units produced}}{\text{Duration of time period}}$

$\text{Flow time}=\frac{10}{2}$

$\text{Flow time}=5$

Therefore, on average bank customers wait in line for 5 minutes.
