AnnZ [28]

Answer:

  • A. 3 weeks, $160

Step-by-step explanation:

If the value of y is same for both then we have equal right sides of equations

  • 50x + 10 = 30x + 70

Solve this for x

  • 50x - 30x = 70 - 10
  • 20x = 60
  • x = 60/20
  • x = 3

Find the value of y

  • y = 50*3 + 10 = 150 + 10 = 160

Correct choice is A

eimsori [14]

Answer:

You should perform x trials until you observe a success.

Step-by-step explanation:

By process of elimination:

A binomial experiment is a statistical experiment that must meet certain requirements:

Each outcome is either a success (P) or a failure (Q).

All trials are independent.

There are a fixed number of "n" trials.

The probability of success, p, is the same for each trial.
