The probability = outcome/total outcomes

The total of the outcomes is the total number of the letters of the given word, then

The total outcomes = 11

The outcome is the number of letter "s" in the word

The outcome = 4, then

The probability of "s" is

P(s)=\frac{4}{11}

To change it to percent multiply it by 100% and round it to the nearest 1 decimal place

\begin{gathered} P(s)=\frac{4}{11}\times100 \\ P(s)=36.4 \end{gathered}

The answer is 36.4%

The distance between the cities Atlanta and Indianapolis is 540 miles. A motorcycle's speed is 48 mph. For a car it takes 2.25 h
bezimeni [28]

Answer:


Step-by-step explanation:

let they travel the distance between them alone

d = common distance traveled by both motorcycle and car = 540 miles

t_{m}= time taken by motorcycle to travel distance between them

v_{m} = speed of the motorcycle = 48 mph

time taken by motorcycle to travel distance between them is given as

t_{m}= d/v_{m}

t_{m}=540/48

t_{m}= 11.25 h



t_{c}= time taken by car to travel distance "d" =11.25 - 2.25 = 9 h

v_{m} = speed of the motorcycle

speed of motorcycle is given as

v_{m} = d/t_{m}

v_{m} = 540/9

v_{m} = 60 mph


when the car and motorcycle move towards each other, the relative speed is given as

v = v_{m} + v_{c}

v = 60 + 48

v = 108 mph

t = time taken to meet

Time taken to meet is given as

t = d/v

t = 540/108

t = 5 h

There are 15 students in a class. 9 of them play basketball, and 11 of them play soccer. How many students in the class play bot
Bezzdna [24]

We will see that the number of students that play both sports is given by the inequality:

5 ≤ x ≤ 9

<h3>How to find the number of students that play both sports?</h3>

We do know that in the class, there are 15 students.

Such that:

  • 9 of them play basketball.
  • 11 of them play soccer.

If you add these numbers, you get:

9 + 11 = 20

This gives more than the number of students that we have, to get the minimum <em>number of students</em> that play both sports we subtract the number of students:

20 - 15  = 5

5 students play both sports, but this is the minimum number.

There is also the case where out of the 11 students that play soccer, there are 9 that play basketball (so 9 students play both sports) and 4 students don't play any sport.

So the number of students that play both sports is given by the inequality:

5 ≤ x ≤ 9
