Solution: Yes, the random variable y will have a binomial distribution. Because there are two possible outcomes 1. number of days of rain and 2. number of days of no rain.

The parameters of binomial distribution are n and p

The parameter n is given as the number of day's under consideration.

\therefore n=30

The parameter p is not given, but it can be estimated by number of days it rained divided by the total number of days under consideration.

\therefore p=\frac{y}{n} =\frac{y}{30}

Sonja [21]

Answer:she spent 10 hours working in her aunt's store last week.

Step-by-step explanation:

Let x represent the number of hours that Lee spent working at the movie theater.

Let y represent the number of hours that Lee spent working at her aunt's store.

Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that

x + y = 30

Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that

9x + 6y = 240 - - - - - - - - - -1

Substituting x = 30 - y into equation 1, it becomes

9(30 - y) + 6y = 240

270 - 9y + 6y = 240

- 9y + 6y = 240 - 270

- 3y = - 30

y = - 30/ - 3 = 10 hours

Reil [10]

Answer:  G

<u>Step-by-step explanation:</u>

(x, y) → (\frac{1}{8}x, \frac{1}{8}y)

means that the new quadrilateral will be \frac{1}{8} the size of the original quadrilateral, so it will be smaller because the it maps to a fraction that is less than 1.
