I need help ASAP <br>Solve 2(x + 1) = 2x + 5. All real numbers No solution 0 3

Mice21 [21]

Answer: No solution 0=3

Step-by-step explanation:

2(x+1)=2x+5

Step 1: Simplify both sides of the equation.

2(x+1)=2x+5

(2)(x)+(2)(1)=2x+5(Distribute)

2x+2=2x+5

Step 2: Subtract 2x from both sides.

2x+2−2x=2x+5−2x

2=5

Step 3: Subtract 2 from both sides.

2−2=5−2

0=3

Answer:

There are no solutions.

Okay i know the answer but how to write it as an expression???<br> please help

givi [52]

Answer:

to write an expression, we often have to interpret a written phrase. For example, the phrase “ 6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.

A football team has a probability of .75 of winning when playing any of the other four teams in its conference. If the games are

Alexeev081 [22]

Answer:

0.3164 = 31.64% probability the team wins all its conference games

Step-by-step explanation:

For each conference game, there are only two possible outcomes. Either the team wins it, or they lose. The probability of winning a game is independent of any other game. This means that the binomial probability distribution is used 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.

A football team has a probability of .75 of winning when playing any of the other four teams in its conference.

The probability means that $p = 0.75$ , and four games means that $n = 4$

If the games are independent, what is the probability the team wins all its conference games?

This is P(X = 4). So

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

$P(X = 4) = C_{4,4}.(0.75)^{4}.(0.25)^{0} = 0.3164$

0.3164 = 31.64% probability the team wins all its conference games
