Calculate the probability of tossing a coin 6 times and getting the given number of tails. I get that I'll be using 1/2 for the problem but that's it..

if you can just please explain step by step , I don't understand .. thank you !

#1 : 0

For the given statement, write the if-then form, the converse , the inverse, and the contrapositive.

1) the complementary angles add to 90 degrees.

2) ants are insects.

For the given statement, write the if-then form, the converse , the inverse, and the contrapositive.

1) the complementary angles add to 90 degrees.

2) ants are insects.

Decide whether the statement is true or false.If false, provide a counterexample.

1) if m <a is 85 degrees, then the measure of the complement of <a is 5 degrees.

2) supplementary angles are always linear pairs.

3) if a number is an integer, then it is rational.

4)if a number is a real number, then it is irrational.

Rewrite the definition as a biconditional statement.

1)an angle with a measure between 90 degrees and 180 degrees is called obtuse .

2) two angles are a linear pair if they are adjacent angles whose non common sides are opposite rays.

3)coplanar points are points that lie in the same plane.

Decide whether the statement is true or false. If false, provide a counterexample.

1) if m <a is 85 degrees, then the measure of the complement of <a is 5 degrees.

2) supplementary angles are always linear pairs.

3) if a number is an integer, then it is rational.

4)if a number is a real number, then it is irrational.

For the given statement, write the if-then form, the converse , the inverse, and the contrapositive.

1) the complementary angles add to 90 degrees.

2) ants are insects.

This is my first time doing this and in lost , in only an 8th grader :(

Rewrite the conditional statement in if-then form.

1) when x=6,x^2=36

2) the measure of a straight angle is 180 degrees.

3)only people who are registered are allowed to vote.

A diesel train left the station and traveled toward the fueling station at an average speed of 90 km/h. A freight train left one hour later and traveled in the opposite direction with and average speed of 4 km/h. find the number of hours the freight train needs to travel before the trains are 30 km apart.

Please explain :)

There are 2 questions,you don't have to answer both but I would appreciate it if you do :)

1) Castel left the hardware store and traveled toward his cabin on the lake. Eduardo left two hours later traveling 24 mph faster in an effort to catch up.After three hours Eduardo finally caught up.Find Castel's average speed.

2) Alberto left the hardware store and drove toward the lake at an average speed of 40 mph. Castel left at the same time and drove in the opposite direction with an average speed of 70 mph. How long does Castel need to drive before they are 660 mi. apart.

Please explain :)
