The length of a text messaging conversation is normally distributed with a mean of 2 minutes and a standard deviation of 0.5 min
zhenek [66]

Answer:

Let x be a random variable representing the length of a text messaging conversation, then

P(x > 3) = 1 - P(x < 3) = 1 - P(z < (3 - 2)/0.5) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275

An amusement park sells adult tickets and children’s tickets, with adults tickets costing $5 and children’s tickets costing $3.
Katarina [22]

Answer:

Nine

Step-by-step explanation:

3 dollars for children tickets : x

5 dollars for adult tickets: y

Equation is:

3x+5y=57

Where 57 is the total amount spent

x+y=15  

where 15 is the total number of tickets bought

3x+5y=57

5(x+y)=5(15)

___________________

3x+5y=57

5x+5y=75

minus the equations top to bottom=

-2x= -18

x= -18/(-2)

x=9

He bought a total of 9 children tickets

Determine whether each sum, difference, product,
PIT_PIT [208]

Answer:

28. The difference represents an irrational number

29. The difference represents a rational number

30. The quotient represents a rational number

31. The quotient represents an irrational number

Step-by-step explanation:

* Lets explain how to solve the problem

- The rational number is any numbers can be put in the form of a/b,

  where a and b are integers b ≠ 0

- Ex: 1 , 2/3 , 5/4 , 22/7 , 100 , ................

- The irrational number is any number that is not rational

- It is a number that cannot be written as a ratio of two integers

 or cannot be expressed as a fraction

- Ex: √2 , √7 , π ,  ..... (π is irrational because it's approximated value)

- If the part of the the number is irrational, then the number

 is irrational

- Ex: (5 + √3) , (√7 + 5) , 2√5 , √11/4 , 5/√13

* Lets solve the problems

28. \frac{6}{23}-\frac{\sqrt{2}}{2}

∵ √2/2 is an irrational number

∵ One term is an irrational number

∴ The difference represents an irrational number

29. \frac{6}{23}-\frac{15}{127}

∵ The two terms are rational numbers

∴ The difference represents a rational number

30. \frac{6}{23} ÷ \frac{15}{127}

∵ The two terms are rational numbers

∴ The quotient represents a rational number

31. \frac{6}{23} ÷ \frac{\sqrt{2}}{2}

∵ √2/2 is an irrational number

∵ One term is an irrational number

∴ The quotient represents an irrational number
