Answer:

-4

Step-by-step explanation:

Answer:

  (a) 0.65

  (b) 3/7

  (c) 6/13

Step-by-step explanation:

(a) P(C') = 1 - p(5) -p(6) = 1 - 0.15 - 0.2

  P(C') = 0.65

__

(b) P(B|C) = P(BC)/P(C) = P(5)/(P(5)+P(6)) = 0.15/(0.15 +0.2)

  P(B|C) = 3/7

__

(c) P(B'|C') = P(B'C')/P(C') = (P(1) +P(2))/0.65 = (0.15+0.15)/0.65

  P(B'|C') = 6/13

Answer:

10x + 80      greater than or ewual to 200

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since the 2 horizontal lines are parallel,

angle 1 and 3 are corresponding angles and hence equal

So, angle 1  = angle 3

20x + 60 = 30x + 20

10x = 40

x = 4

Now, finding angle 1

Angle 1 = 20x + 60

Angle 1 = 20 (4) + 60

Angle 1 = 140 degrees

____________________________

Step-by-step explanation:

____________________________

Given:

 63 – 4 = 8 (2+1/4s) ; Solve for: "s" ;

Note: Rewrite the equation:

↔  8 (2+1/4s) = 63 - 4 ;   (commutative property);

Start with the "right-hand side" of the equation:

  " 63 − 4 " ;  which equals:  " 59. "

___________________________

Rewrite the equation:

___________________________

  →   8 (2 + 1/4s)  =  59 ;

Now, let us examine the "left-hand side" of the equation:

     " 8 (2 + 1/4s) " ;

Note the "distributive property" of multiplication:

           a(b + c) = ab + ac ;

As such:

       " 8 (2 + 1/4s) " ;

                     =  (8×2)  + (8× 1/4s) ;

                     =  16 + 8/4s ;

                      = 16 + 2s ;

Now, rewrite the equation:

                       16 + 2s = 59  ;  Subtract "16" from each side of the equation:

          16 + 2s − 16 = 59 − 16 ;

to get:   2s  = 43 ;

Now, divide each side of the equation by "2" ;  

 to isolate "s" on one side of the equation; & to solve for "s" ;

             2s / 2 =  43 / 2 ;

 to get:

              s =  21. 5 ;  

                  or;  write as " [tex]21 \frac{1}{2}[/tex]  " .

Answer:

8,510,002, 8,510,003, 5,510,004

Answer:

4 and 9

Step-by-step explanation:

let their ages be x and x - 5, then in 4 years their ages will be

x + 4 and x - 5 + 4 = x - 1 , and the product is 104, thus

(x + 4)(x - 1) = 104 ← expand factors on left using FOIL

x² + 3x - 4 = 104 ( subtract 104 from both sides )

x² + 3x - 108 = 0 ← in standard form

(x + 12)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 12 = 0 ⇒ x = - 12

x - 9 = 0 ⇒ x = 9

However, x > 0 ⇒ x = 9

Thus

Their present ages are 9 and 9 - 5 = 4

Answer:

The sum of 2 negative fractions will be negative, and the sum of 2 positive fractions will be positive.  They are similar because if you have the same number, just one positive and one negative, the absolute value of the sum of the 2 problems will be the same.  

Step-by-step explanation:

^

The least common denominator might be the same for both fractions but the result will be different due to their signs

Fractions are represented as the ratio of two integers. For instance, a/b is a fraction where a and b are integers

The sum of two positive fractions will result in a positive fraction while the difference of two negative fractions will result in negative fractions.

For example 1/2 + 1/2 = 1 while -1/2-1/2 = -1

Note that the least common denominator might be the same for both fractions but the result will be different due to their signs

Answer:

150 ft

Step-by-step explanation:

The diagram shown gives us a picture of two similar right triangle.

The height of the man is similar to the height of the platform.

To find the height of the platform, multiply the height of the man by the scale factor.

Scale factor = the ratio of any corresponding sides of two similar triangles.

Scale factor = 100 ft ÷ 4 ft = 25

Height of man = 6ft

Therefore, height of platform = 6 ft × 25 = 150 ft

A ) Let p be the probability of getting affected . Probability of not getting affected be q

p = .3 , q = .7

If n be the member of family , probability that x children will be affected will be given by the expression

p(x) = ⁿCₓ pˣqⁿ⁻ˣ

n = 2 , x=2

p(2) = ²C₂ .3².7²⁻²

= 1 x .09 x 1 = .09

B )

p(1) = ²C₁ .3¹.7²⁻¹

=  2 x .3 x .7

= .42

C ) x = 0

p (0) = ²C₀ .3⁰.7²⁻⁰

=  1 x 1 x .49

= .49

D ) Let A be the probability that older child is affected and B be the probability that younger child is affected

P( A /B ) = P(A∩B) / P(B )

= .09 / .42

The area of the triangle QRS vertices have coordinates as (-1,2), (1,-4) and (-2,-2) is given by: Option: 7 sq. units.

Suppose the vertices of the considered triangle ABC are on [tex]A(A_x,A_y), B(B_x,B_y), C(C_x,C_y)[/tex], then, the area of the triangle is given by:

[tex]Area = \dfrac{|A_x(B_y-C_y) + B_x(C_y-A_y) + C_x(A_y-B_y)|}{2}[/tex]

For this case, we're specified that:

Coordinates of the vertices of the triangle QRS are:

(-1,2), (1,-4) and (-2,-2)

Thus, its area is evaluated as:

[tex]Area = \dfrac{|-1(-4-(-2)) + 1(-2-2) + (-2)(2-(-4))|}{2} = \dfrac{|2-4-12|}{2}\\\\Area = \dfrac{14}{2} = 7 \: \rm unit^2[/tex]

Thus, the area of the triangle QRS vertices have coordinates as (-1,2), (1,-4) and (-2,-2) is given by: Option: 7 sq. units.
