Annie has a lemonade stand and her mom pays her 5 dollars every week for her to go get her supplies. Her dad pays her ten dollars one week. She has 35 dollars that month. How many weeks did Annie’s mom pay her?

35 - 10 = 25

25 divided by 5 equals 5.

To check: 5 x 5 equals 25 plus 10 equals 35

The probability that a randomly selected 3-year-old male chipmunk will live to be 4 years old is 0.96516.
mezya [45]

Using the binomial distribution, it is found that there is a:

a) The probability that two randomly selected 3-year-old male chipmunks will live to be 4 years old is 0.93153 = 93.153%.

b) The probability that six randomly selected 3-year-old male chipmunks will live to be 4 years old is 0.80834 = 80.834%.

c) The probability that at least one of six randomly selected 3-year-old male chipmunks will not live to be 4 years old is 0.19166 = 19.166%. This probability is not unusual, as it is greater than 5%.

-----------

For each chipmunk, there are only two possible outcomes. Either they will live to be 4 years old, or they will not. The probability of a chipmunk living is independent of any other chipmunk, which means that the binomial distribution is used to solve this question.

Binomial probability distribution  

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

In this problem:

  • 0.96516 probability of a chipmunk living through the year, thus p = 0.96516

Item a:

  • Two is P(X = 2) when n = 2, thus:

P(X = 2) = C_{2,2}(0.96516)^2(1-0.96516)^{0} = 0.9315

The probability that two randomly selected 3-year-old male chipmunks will live to be 4 years old is 0.93153 = 93.153%.

Item b:

  • Six is P(X = 6) when n = 6, then:

P(X = 6) = C_{6,6}(0.96516)^6(1-0.96516)^{0} = 0.80834

The probability that six randomly selected 3-year-old male chipmunks will live to be 4 years old is 0.80834 = 80.834%.

Item c:

  • At least one not living is:

P(X < 6) = 1 - P(X = 6) = 1 - 0.80834 = 0.19166

The probability that at least one of six randomly selected 3-year-old male chipmunks will not live to be 4 years old is 0.19166 = 19.166%. This probability is not unusual, as it is greater than 5%.

MakcuM [25]

By definition, a rectangle is:

Any four sided polygon (quadrilateral) that contains four right angles.

By extension, a square is:

Any rectangle where all sides are of the same, or equal, length.

<h3>So yes, a square is always a rectangle.</h3>

PROBLEM. 11.1: Rewrite These! Rewrite each quotient as a sum or a difference.
Jet001 [13]

Answer:

1. (4x-10)/2

   4x/2 - 10/2

    2x - 5

2. (1-50x)/-2

   1/-2 -50x/-2

   25x - 1/2

3. 5(x + 10)/25

   (5x + 50)/25

   5x/25 + 50/25

   1/5 x + 2

4.(-0.2x + 5)/2​

   -0.2x/2 + 5/2

   -0.1x + 2.5
