2. Use the following statement to answer ALL three parts of the question.
Statement: If two lines do not intersect, then they are parallel.
(a) Write the inverse of the statement. Is the inverse true or false? Explain your reasoning.
(b) Write the converse of the statement. Is the converse true or false? Explain your reasoning.
(c) Write the contrapositive of the statement. Is the contrapositive true or false? Explain your reasoning.

Answers

a) The inverse of the statement is the opposite. The statement stated that if two lines do not intersect, they are parallel. So, the opposite would be if two lines intercept, they are parallel. This inverse statement is false because, that is not true. Parallel lines mean they never intercept, not if they intercept its parallel.

b) Converse means to engage or explain, I think…so, the converse of the statement would be that yes, it is true that when two lines do not intercept then they are parallel. Because parallel lines never cross or meet, meaning they will NEVER ever have a crossing point.

c) the contrapositive of the statement would be: if two lines do not cross then they are parallel. If they do intercept, then they are not parallel. As simple as that. I think contrapositive means that…I looked what contrapositive means…so I think I’m right.

I hope this helps!! Or some at least. :)

Good luck!

m=3

y-y1=m(x-x1)

A rental car agency charges $220.00 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $380.00?

Answers

40 miles per week

Step-by-step explanation:

380-220 = 160÷4 = 40

You can travel 320 miles in one week for $320 miles.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

A rental car agency charges $220.00 per week plus $0.25 per mile to rent a car.

If the amount is $380.

Then, 380 - 220 = 160

And 160 divided by 0.5,

= 160/0.5

= 320 miles.

Therefore, the required distance is 320 miles.

In the game of Scrabble, each player begins by drawing 7 tiles from a bag containing 100 tiles. There are 42 vowels, 56 consonants, and 2 blank tiles in the bag. Cait chooses her 7 tiles and is surprised to discover that all of them are vowels. Can we use a binomial distribution to approximate this probability?

Answers

Considering the hypergeometric variable, it is found that since the population size is less than 20 times the sample size, the binomial distribution cannot be used.

The tiles are chosen without replacement, hence, the hypergeometric distribution is used.

The population is composed by the 100 tiles.The sample is composed by 7 tiles.

The hypergeometric distribution can be approximated to the binomial if the population size is at least 20 times the sample size.

[tex]\frac{100}{7} = 14.28 < 20[/tex]

Hence, the binomial distribution cannot be used.

Answers

The expression that represents the required distance is [tex]\mathbf{ s = \frac{h}{0.5878}}[/tex]

The given parameters are:

[tex]\mathbf{\theta =36^o}[/tex] --- the angle of elevation to the top of the tree

To do this, we make use of the following representations

s represents the distance from the tip of the shadow to the top of the treeh represents the height of the tree

The distance (s) is then calculated using the following sine ratio

[tex]\mathbf{ sin(\theta) = \frac{h}{s}}[/tex]

Make s the subject

[tex]\mathbf{ s = \frac{h}{sin(\theta)}}[/tex]

Substitute [tex]\mathbf{\theta =36^o}[/tex]

[tex]\mathbf{ s = \frac{h}{sin(36)}}[/tex]

Evaluate sin(36)

[tex]\mathbf{ s = \frac{h}{0.5878}}[/tex]

The height of the tree is not known.
