Answer: Simple random sample

Step-by-step explanation:

  • A sample of a statistical population in which each participant of the sample has an equal probability of being chosen is called a simple random sample.

The given statement : A manager associated each employee's name with a number on one ball in a container, then drew balls without looking to select a sample of 555 employees.

Here the probability of each employee has equal chances of being selected.

Hence, this is a simple random sample.

Ierofanga [76]

Answer:

1. 2x - 5 + x = 20

Step-by-step explanation:

Let Aseem's car as x,

Stana's = 5 less than 2x

Aseem's + Stana's = 20

x + 2x - 5 = 20

2x - 5 + x = 20

Without actually writing the formula, explain how to expand (x + 3)7 using the binomial theorem.
Lyrx [107]

To write the coefficients of the 8 terms, either start with a combination of 7 things taken 0 at a time and continue to 7 things taken 7 at a time or use the 7th row of Pascal’s triangle.

For the first term, write x to the 7th power and 3 to the 0 power. Then decrease the power on x and increase the power on y until you reach x to the 0 and y to the 7.

Simplify by evaluating the coefficients and powers 3

Arte-miy333 [17]

Answer:    \frac{1}{16}


Step-by-step explanation:

Given: The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders the day before the game was released.

The probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released

=\frac{35}{140}\times\frac{35}{140}=\frac{1}{4}\times\frac{1}{4}=\frac{1}{16}

Hence, The probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released is \frac{1}{16}.
