Cut out 18%
100=all,
all-cut out=remaining
100-18=82

A bird catches a fish, flies 100 yards upward in a straight line, and then drops the fish. The fish lands at a spot that is 50 y
Marina CMI [18]
You can solve this using trigonometric functions.

The angle between the fish and the ground is
tan θ = 100 / 50
θ = tan-1 (2)
θ = 63.43°

The height of the bird before it dropped the fish is already given, which is 100 yards.

In a math class with 29 students, a test was given the same day that an assignment was due. There were 22 students who passed th
Phoenix [80]

4/29 is the probability that a student who did not complete the homework passed the test.

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

It is given that,

There are 29 students in a math class.

Two types of students who passed the test and are not passed the test.

The other two types of students are who completed the assignment and did not complete the assignment.

So, the given data can be formed as a table.

  • There were 22 students who passed the test.
  • There were 20 students who completed the assignment.
  • There were 18 students who passed the test and also completed the assignment.

                                         Passed the test     Not passed the test    Total

Completed assignment        18                             -                             20

Not completed assignment   x                             -                                -

Total                                       22                           -                               29

Now, you need to find the probability that a student who did not complete the homework passed the test.

⇒ No.of students completed assignment passed the test / Total students.

<u>To find the no.of students completed assignment passed the test :</u>

Let 'x' is the no.of students completed assignment passed the test.

⇒ 18+x = 22

⇒ x = 22 - 18

⇒ x = 4

∴ P(students completed assignment passed the test) = 4 / 29.
