Answer:

79.31%

Step-by-step explanation:

First we need to find the total number of students.

We do that summing all the four values in the table:

Total students = 2 + 18 + 3 + 6 = 29

Then, the students that play a sport or an instrument are all student but the ones that don't play both:

Students(sport or instrument) = 29 - 6 = 23

So the probability of a random student playing a sport or an instrument is 23/29 = 0.7931 = 79.31%

A pipe of length 1/2 yd is cut into 5 equal pieces. What is the length of each piece in yards?

avanturin [10]

The length of each piece is 0.1 yard.

<u>Step-by-step explanation:</u>

The length of the pipe is $\frac{1}{2}$ yard.

The pipe is cut into 5 equal pieces.

We have to find the length of the each piece.

The length of the each piece is calculated by dividing the pipe's initial length(L) by the the number of pieces(N).

Length of the each piece = $\frac{L}{N}$ .

= $\frac{\frac{1}{2}}{5}$ . ( 5 is also written as $\frac{5}{1}$ ⇒ $\frac{\frac{1}{2} }{\frac{5}{1} }$ .)

= $\frac{1}{2}$ × $\frac{1}{5}$ .

= $\frac{1}{10}$ .

= 0.1 yard.

Length of the each piece = 0.1 yard.

how do the values compare ? order the values from greatest to least 3/4 , - 1 3/4 , -1 1/4, - 2 1/4, 2 1/4, 1 1/4

natali 33 [55]

Answer:

The order of the values from greatest to least are as

$\frac{21}{4} > \frac{11}{4} > \frac{3}{4} > \frac{-11}{4} > \frac{-13}{4} > \frac{-21}{4}$

Step-by-step explanation:

Negative number goes on decreasing in this way as -1,-2,-3,-4,-5... and so on.

So,-11 > -13 > -21

Here the denominator is same and the numerator is in decreasing order i.e greatest to the least that is 21 > 11 > 3 > -11 > -13 >-21 .Therefore, the order is

$\frac{21}{4} > \frac{11}{4} > \frac{3}{4} > \frac{-11}{4} > \frac{-13}{4} > \frac{-21}{4}$
