Answer:

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Step-by-step explanation:

Given

[tex]S = \{1,2,3,4,5\}[/tex]

[tex]n(S) = 5[/tex]

Required

[tex]P(x > 1\ and\ x < 2)[/tex]

[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:

[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]

Since it is a probability with replacement, we have:

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

For x > 1, we have:

[tex]x > 1 = \{2,3,4,5\}\\[/tex]

[tex]n(x > 1) = 4[/tex]

For x < 2, we have:

[tex]x < 2 = \{1\}[/tex]

[tex]n(x < 2) = 1[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

becomes

[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

5x = 45

divide both sides by 5

x = 9

Answer:

x = 9

Step-by-step explanation:

49 degrees and (5x + 4) are vertical lines, meaning they are congruent.

We can make an equation with this information:

(5x + 4) = 49

SAVE SPIRIT WEEK By David Pinsky Teachers at Harrison Middle school feel that Spirit week should be canceled. They argue that it interrupts classes in many ways. Students may forget to do their homework as they concentrate on the Spirit Week themes. A few students skip classes and some go to a different lunch period. Students spend extra time in the bathrooms combing their hair and adjusting their outfits. Some students goof around in class and find it hard to settle down. If Spirit Week isnt canceled, teachers warn that school will no longer be a good place to learn. We, the students, feel that Spirit Week encourages us to be better students. Spirit Week is a way for us to show our creativity. For example, last year we had a 70s theme. Students learned how a person dressed during this decade, and they tried to imitate those fashions. Such a theme teaches us about culture and history. Spirit week also gives us feelings of pride. At the end of the week, we wear our school colors and support our basketball team against our rivals, the Wildcats. Finally, we feel that Spirit Week teaches us how to work in groups and how to pan and organize an event. Everyone loves Spirit Week.
