Answer: 0.09

2.25 = 2 1/4
0.04 = 1/25

2 1/4 (Equals 9/4 In Improper Fraction Form) x 1/25 
9/4 x 1/25 = 9/100
9/100 Equals 0.09

6. a. Sixty students in a class took an examination in Physics and Mathematics. If 17 of them passed Physics only, 25 passed in
Ivahew [28]

Let C be the set of all students in the <u>c</u>lassroom.

Let P and M be the sets of students that pass <u>p</u>hysics and <u>m</u>ath, respectively.

We're given

n(C) = 60

n(P \cap M') = 17

n(P \cap M) = 25

n((P \cup M)') = n(P' \cap M') = 9

i. We can split up P into subsets of students that pass both physics and math (P\cap M) and those that pass only physics (P\cap M'). These sets are disjoint, so

n(P) = n(P\cap M) + n(P\cap M') = 25 + 17 = \boxed{42}

ii. 9 students fails both subjects, so we find

n(C) = n(P\cup M) + n(P\cup M)' \implies n(P\cup M) = 60 - 9 = 51

By the inclusion/exclusion principle,

n(P\cup M) = n(P) + n(M) - n(P\cap M)

Using the result from part (i), we have

n(M) = 51 - 42 + 25 = 34

and so the probability of selecting a student from this set is

\mathrm{Pr}(M) = \dfrac{34}{60} = \boxed{\dfrac{17}{30}}

For the following right triangle, find the side length x. Round your answer to the nearest hundredth.
anastassius [24]

Answer:

  15.62

Step-by-step explanation:

The Pythagorean theorem tells you the relation between the side lengths is ...

  x^2 = 12^2 + 10^2 . . . the sum of squares of sides is the square of the hypotenuse

  x^2 = 244

  x = √244 ≈ 15.62

I really need help with this.

Answer:

  a.  (1.4, 2.6)

  b.  (3, 2)

Step-by-step explanation:

a. The circumcenter is the intersection point of the perpendicular bisectors of the sides of the triangle.

For points X(a, b) and Y(c, d), the perpendicular bisector of XY can be written as ...

  (c -a)(x -(c+a)/2) +(d -b)(y -(d+b)/2) = 0

Then the equation of the perpendicular bisector of MN is ...

  (-2-4)(x -(-2+4)/2) +(4-0)(y -(4+0)/2) = 0

  -6(x -1) +4(y -2) = 0

  3x -2y = -1 . . . .  divide by -2 and put in standard form

Similarly, the perpendicular bisector of NO is ...

  (0-(-2))(x -(0-2)/2) +(6 -4)(y -(6+4)/2) = 0

  2(x +1) +2(y -5) = 0

   x + y = 4 . . . . divide by 2 and put in standard form

So, the point of intersection is ...

  (3x -2y) +2(x +y) = (-1) +2(4) . . . . . add twice the 2nd equation to the 1st

  5x = 7 . . . . . . simplify

  x = 1.4 . . . . . . divide by 5

  y = 4-1.4 = 2.6 . . . . . find y from the second equation

The coordinates of the circumcenter are (1.4, 2.6).

__

b. The centroid is the average of the vertex coordinates.

  centroid = (A +B +C)/3 = ((1, 2) +(3, 4) +(5, 0))/3 = (1+3+5, 2+4+0)/3 = (9, 6)/3

  centroid = (3, 2)
