Jasmine created this spinner to predict whether a randomly selected student in her school will be traveling during the upcoming
777dan777 [17]

Answer:

The number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.

Step-by-step explanation:

The spinner created by Jasmine, to predict whether a randomly selected student in her school will be traveling during the upcoming holiday break, has 8 equal sections labeled:

{yes, yes, no, no, no, no, no, no}

So, there are two sections labeled yes and six labelled as no.

Compute the probability of a yes as follows:

P(\text{yes})=\frac{2}{8}=0.25

Jasmine selected <em>n</em> = 36 students in her gym class.

If a student in her school will be traveling during the upcoming holiday break is independent of the other students.

Let the random variable <em>X</em> be defined as the number f students that will be traveling during the upcoming holiday break.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 36 and <em>p</em> = 0.25.

Compute the expected value of <em>X</em> as follows:

E(X)=np\\=36\times 0.25\\=9

Thus, the number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.

The variable z is inversely proportional to x. When x is 16, z has the value 0.9375.
Setler [38]

Since z is inversely proportional to x, when x increases by a factor of 26/16, z will be multiplied by the inverse of that factor: 16/26

z=\dfrac{16}{26}\cdot 0.9375=0.5\overline{769230}=\dfrac{15}{26}

A standard unit of measurement in astronomy is the astronomical unit, or au. it equals is about 150,000,000,000 m. in 2000, pion
Maurinko [17]

First we convert the m to km by dividing the number by 1000. 1000m = 1 km.

150,000,000,000 / 1000 = 150,000,000 km

Now we divide 150,000,000/11,000,000 = 13.6363636364 au.
