16 teams In a football league, each team plays each other twice , how many games are there in the football league in total ?
Brilliant_brown [7]

Answer:

120 games.

Step-by-step explanation:

We have been given that there are 16 teams in a football league. Each team plays each other twice. We are asked to find total number of games are there in the football league.

We will use formula \frac{n(n-1)}{2} to solve our given problem.

Each team will play matches with one team less as it will not play match with itself.

We will divide all number of matches by 2 to avoid repetition.

\frac{16(16-1)}{2}=\frac{16(15)}{2}=8*15=120

Therefore, there are 120 games in the football league.

the sum of the internal angles of a regular polygon is equivalent to 56 right angles. Find the measure of the central angle of t
kykrilka [37]
If x is the number of sides of the regular polygon, then the sum of the interior angles is (x - 2) * 180 = 56 * 90. Solving for x gives 30 for the number of sides of the regular polygon.

To get the central angles measure, divide 360 by 30 to get 12 degrees for the measure of one of the 30 central angles.

Answer: 12 degrees

MrRissso [65]

Answer:

If we define the random variable X ="time spend by the students doign homework"

And we want to tes t is students spend more than 1 hour doing homework per night, on average (alternative hypothesis), so then the system of hypothesis for this case are:

Null hypothesis: \mu \leq 1

Alternative hypothesis: \mu >1

And they wnat to use a sample size of n = 100 and a significance level of 0.05

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

Solution to the problem

If we define the random variable X ="time spend by the students doign homework"

And we want to tes t is students spend more than 1 hour doing homework per night, on average (alternative hypothesis), so then the system of hypothesis for this case are:

Null hypothesis: \mu \leq 1

Alternative hypothesis: \mu >1

And they wnat to use a sample size of n = 100 and a significance level of 0.05
