Answer:

0.303

Step-by-step explanation:

The number of students who plays both flute and Piano can be obtained thus :

Let numbwr who plays both =x

Piano only + flute only + both + neither = total

12 + 1 + x + 10 = 33

23 + x = 33

x = 33 - 23

x = 10

Hence, probability that student plays both instrument :

P = required outcome / Total possible outcomes

P(plays both) = 10 / 33 = 0.303

Write the equation of the line that is parallel to the line and through the given point y=-2x+1 point (0,5)
marysya [2.9K]

Answer:

y = -2x+5

Step-by-step explanation:

y = -2x+1 is in the form y= mx+b where m is the slope and b is the y intercept

-2 is the slope

Parallel lines have the same slope so our new line will have the same slope

y = -2x+b

The point given is the y intercept (value when x is zero)

b = 5

y = -2x+5

What percent of students ran the mile in 12 minutes or less?
otez555 [7]
41% of students ran in 12 minutes or less.

Using the histogram we see that there were 2+12+11+9=34 students that ran.  Out of those, 2+12=14 ran in 12 minutes or less (the first two bars).

14/34 = 0.411 = 41%.

A fence is 695
Rasek [7]
Let the two parts with equal length have length x.
The longer part has length x + 20.

The sum of the three lengths is 695 m.

x + x + x + 20 = 695

3x + 20 = 695

3x = 675

x = 225

x + 20 = 245

The two short parts measure 225 m, and the long part measures 245 m.
