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.

Answer:

6.3 ft

Step-by-step explanation:

The ladder lying on the wall with an elevation of 39° forms a right angled triangle.

Hypotenuse = length of ladder = 10 ft

Opposite = x = ?

θ = 39°

Use trigonometric ratio formula to find, x, which is how far the ladder goes up the wall.

The trigonometric ratio formula to use is:

sin(θ) = opposite/hypotenuse

Sin(39) = x/10

Multiply both sides by 10

10*sin(39) = x

x = 10*sin(39)

x = 6.29 ≈ 6.3 ft (to nearest tenth)

Mitchell is one of the goalies for an ice hockey team. He wants to be goalie in the game today, but that depends on who coaches
seropon [69]

Answer:

49% probability that Mitchell will be a goalie today

Step-by-step explanation:

Coach White coaches with 70% probability. So 70% of the time, there is a 55% probability that Mitchell is the goalie.

The other 100-70 = 30% of the time, 35% probability that Mitchell will be the goalie.

What is the probability that Mitchell will be a goalie today?

P = 0.7*0.55 + 0.3*0.35 = 0.49

49% probability that Mitchell will be a goalie today
