Answer:

Games played= 21 games

Step-by-step explanation:

Giving the following information:

Peyton's field hockey team wins 4 games out of every 7 games played.

We know that Peyton's team loses 3 games out of 7.

So if the team lost 9 games, the proportion is completed 3 times.

Games played= 3*7= 21 games

The probability that a certain hockey team will win any given game is 0.3723 based on their 13 year win history of 385 wins out
Whitepunk [10]

Answer:

0.1505 = 15.05% probability that the hockey team wins 6 games in November

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the team wins, or it does not. The probability of winning a game is independent of winning other games. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

The probability that a certain hockey team will win any given game is 0.3723

So p = 0.3723

12 games in November

So n = 12

What is the probability that the hockey team wins 6 games in November?

This is P(X = 6)

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 6) = C_{12,6}.(0.3723)^{6}.(1-0.3723)^{6} = 0.1505

0.1505 = 15.05% probability that the hockey team wins 6 games in November

How to solve the problem and the answer plz.
BlackZzzverrR [31]

Answer:

x° =125° y°= 125°

Step-by-step explanation:

55° + x° = 180° because they are complementry angles

solve for x by subtracting 55° from both sides

x° = 125°

x° and y° is equal because they are vertical angles

Write an equation in slope intercept form for the line through the two points
Musya8 [376]
m= \frac{y2-y1}{x2-x1}  \\  \\ m= \frac{-2-2}{2-(-2)}  \\  \\ m= \frac{-4}{4}  \\  \\ m=-1


y=mx+b \\  \\ y=-1x+b


(2)=(-1)(-2)+b \\  \\ 2=2+b \\  \\ 0=b


y=-1x+0 \\  \\ y=-x
