((-2^2)(-1^-3))•((-2^-3)(-1^5))^-2
Vitek1552 [10]

Answer:

  256

Step-by-step explanation:

A calculator works well for this.

_____

None of the minus signs are subject to the exponents (because they are not in parentheses, as (-1)^5, for example. Since there are an even number of them in the product, their product is +1 and they can be ignored.

1 to any power is still 1, so the factors (1^n) can be ignored.

After you ignore all of the things that can be ignored, your problem simplifies to ...

  (2^2)(2^-3)^-2

The rules of exponents applicable to this are ...

  (a^b)^c = a^(b·c)

  (a^b)(a^c) = a^(b+c)

Then your product simplifies to ...

  (2^2)(2^((-3)(-2)) = (2^2)(2^6)

  = 2^(2+6)

  = 2^8 = 256

daser333 [38]

Answer:

d. Twenty-five cars are randomly selected with the new transmission and 25 with the old transmission.

Step-by-step explanation:

A hypothesis test on the difference between the means must satisfy the following conditions

1) the samples must be randomly selected

2) each sample must have a known standard deviation

3) the samples must be independent

4) the samples must be from normal distribution

Hence only part d gives the right answer.

The story is set in the Upper West Sideneighborhood in New York City in the mid 1950s, a multiracial, blue-collar neighborhood. The musical explores the rivalry between the Jets and the Sharks, two teenage street gangsof different ethnic backgrounds. The members of the Sharks, from Puerto Rico, are taunted by the Jets, a white gang.[2] The young protagonist, Tony, a former member of the Jets and best friend of the gang's leader, Riff, falls in love with Maria, the sister of Bernardo, the leader of the Sharks. The dark theme, sophisticated music, extended dance scenes, and focus on social problems marked a turning point in American musical theatre. Bernstein's score for the musical includes "Jet Song", "Something's Coming", "Maria", "Tonight", "America", "Cool", "One Hand, One Heart", "I Feel Pretty", "Somewhere", "Gee, Officer Krupke" and "A Boy Like That".

The original 1957 Broadway production, conceived, directed and choreographed by Jerome Robbins and produced by Robert E. Griffith and Harold Prince, marked Sondheim's Broadway debut. It ran for 732 performances before going on tour. The production was nominated for six Tony Awards including Best Musical in 1958,[3] but the award for Best Musical went to Meredith Willson's The Music Man. Robbins won the Tony Award for his choreography and Oliver Smith won for his scenic designs. The show had an even longer-running London production, a number of revivals and international productions. A 1961 musical film adaptation, directed by Robert Wise and Robbins, starred Natalie Wood, Richard Beymer, Rita Moreno, George Chakirisand Russ Tamblyn. The film was nominated for eleven Academy Awards and won ten, including George Chakiris for Supporting Actor, Rita Moreno for Supporting Actress, and Best Picture.
