Nour and Rana are shopping for a Christmas tree. They are deciding between 222 different types of trees (real and fake) and 444

ioda

From what the statement says the question seems to be to represent the sample space of randomly choosing a type of tree and a color for the decorations

In this case, what we must do is identify the events that exist and the options that each event has, like this:

Event 1:

Tree type: real or fake

Event 2:

Colors for the ornaments: White (W), Silver (S), Gold (G) or Purple (P)

Since in an event there are 2 options and the other 4 options, the final number of options would be 2 * 4, that is, 8 options, represented below:

(real, W), (real, S), (real, G), (real, P), (fake, W), (fake, S), (fake, G), (fake, P)

The above would be the sample space of the events.

Now the probability of 1 coming out is 1 over the event total, or 1/8.

Categorize the following variables as being qualitative or quantitative: (relevant section):

FrozenT [24]

Answer:

1. Quantitative

2. Quantitative

3. Qualitative

4. Qualitative

5. Quantitative

Step-by-step explanation:

A variable is quantitative if it assumes numerical values, for example 1,2,3.

If it assumes "labels", for example good or bad, it is qualitative.

1. Rating of the quality of a movie on a 7-point scale

It assumes numerical values, for example, 1,2,3,...

So it is quantitative

2. Age

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

3. Country you were born in

Descriptive, such as Brazil, USA, Colombia, ...

So it is qualitative.

4. Favorite Color

Descriptive, such as black, brown, red, blue

So it is qualitative

5. Time to respond to a question

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

Prove that if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.

hammer [34]

It is proved that the if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.

According to the statement

we have to prove that the if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.

And for this proof we use the contradiction

So,

Proof by contradiction is a common proof technique that is based on a very simple principle: something that leads to a contradiction can not be true, and if so, the opposite must be true.

So for this purpose,

Assume a is even, so a = 2k for some integer k. Now let a and b be integers such that a divides b and a + b is odd.

Since a divides b, b = an for integer n, and in turn b = 2nk, which means b is even and hence a + b is also even. But this contradicts our initial assumption, so a must be odd.

So, It is proved that the if a and b are nonzero integers, a divides b, and a b is odd, then a is odd.

A.
5x+12=3x+18
2x+12=18
2x=6
x=3
you would get paid the same amount if you worked 3 hours at each job

B.
5(5)+12
10+12
22

3(5)+18
15+18
33

you would get paid more at the second job if you worked for 5 hours
