What is the solution set of {x | x < -3} ∪ {x | x > 5}

Answers

Answer 1

Answer: The union of two sets is defined as all elements that are members of both sets.

The first set evaluuates to (...,...,...-7,-6,-5,-4) and the second eveluates to (6,7,8,9,...,...).

There are no elements that belong to both sets so the solution is the empty set. {∅}

Another way is to think about it in words: "What number(s) are less than -3 and also greater than 5?" There are no numbers that fit both of these.

Hi There! :)

A top fuel dragster can use a s much as 6 gallons in 4seconds to travelmile. At this rate, how many gallonsof fuel will it take for the dragster to go 1mile?

6 gallons in 4 1/2 seconds to travel 1/4 mile
Multiply through by 4

The dragster will :
use 24 gallons in 18 seconds to travel 1 mile.

If the volume for 3-D polyhedra A is 300 cm3 and the volume for 3-D polyhedral B is 900 cm3. How many times bigger is the volume of pyramid B than pyramid A? Select one:
a. 3%
b. 30%
c. 300%
d. 3000%

Answers

Answer:

c. 300%

Step-by-step explanation:

In order to solve this problem you just have to divide the bigger polyhedral by the smaller polyhedral:

$(900 cm^(3) )/(300cm^(3))$

As this is equal to 3, you know that the bigger polyhedral is 3 times bigger than the smaller polyhedral so now you just make a rule of three, if an object that is 100% bigger than other is 1 time bigger, what would be the percentage of an object that is 3 times bigger?

$(1)/(100)=(3)/(x)$

Once you clear the X the equation would look like this:

$x=(3*100)/(1)$

$x=300$

Hello Marie,

V(B)/V(A)=900/300=3=300/100=300%

A jar contains 4 red marbles, numbered 1 to 4, and 11 blue marbles numbered 1 to 11. A marble is chosen at random. If you're told the marble is red, what is the probability that it has the number 2 on it?

Answers

Answer:

25%

Step-by-step explanation:

So there are four marbles that are red.

It doesnt matter if we have a probability of picking blue because the question says you are picking red.

There are four possible outcomes and one favorable outcome so it is 1/4 of 25/100 or 25%

If my answer is incorrect, pls correct me!
