The area of the triangle QRS vertices have coordinates as (-1,2), (1,-4) and (-2,-2) is given by: Option: 7 sq. units.
How to find the area of a triangle whose vertices' coordinates are given?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.

A sample space contains six sample points and events A, B, and C as shown in the Venn diagram. The probablities of the sample points are P(1)=0.15, P(2)=0.15, P(3)=0.15, P(4)=0.2, P(5)=0.15, P(6)=0.2.
Use the Venn diagram and the probabilities of the sample points to find:
P(B|C)
P(B¯¯¯¯|C¯¯¯¯)
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

A zip line runs from the top of a platform on the edge of a pond to the ground across the pond. A camp counselor places a mirror on the edge of the pond across from the platform and stands back until the top of the platform is visible in the mirror. Use similar triangles to find the height of the platform.
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

Answer: " s = 21. 5 " ; or, write as: " s = [tex]21\frac{1}{2}[/tex] "
____________________________
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] " .

How is adding two negative fractions like adding two positive fractions, and how is it different?
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

Suppose that a disease is inherited via a dominant mode of inheritance and that only one of the two parents is affected with the disease. The implications of this mode of inheritance are that the probability is 0.3 that any particular offspring will get the disease, and is 0.15 that all the offspring will get the disease.
A) What is the probability that in a family with two children, both siblings are affected?B) What is the probability that exactly one sibling is affected?C) What is the probability that neither sibling is affected?D) Suppose the older child is affected. What is the probability that the younger child is affected?
Answer:
Step-by-step explanation:
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
= .214

How do I do this problem?
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

Which of the following statements are true? Remember that a mathematical statement is said to be true if it is always true, under all circumstances.
A. Every matrix equation Ax b corresponds to a vector equation with the same solution set.
B. If A is an m x n matrix and if the equation Axb is inconsistent for some b in R", then A cannot have a pivot in every row.
C. The first entry in the product Ax is a sum of products.
D. If the augmented matrix [A l b] has a pivot position in every row, then the equation Ax-b is inconsistent.
E. The equation Ax-b is consistent if the augmented matrix [A I b] has a pivot position in every row.
F. If A is an m x n matrix whose columns do not span Rm, then the equation Ax-b İs inconsistent for some b in R.
Answer:
A, B, C, F
Step-by-step explanation:
Statement A is true.
All the matrix equation of the order always corresponds to any vector equation having the same solution set.
Statement B is true.
If P is any matrix of the order m x n and if the equation [tex]$Px=b$[/tex] is inconsistent for any b in [tex]$R^m$[/tex] , then P does not have a pivot in all the rows.
Statement C is true.
The first entry of elements in a product Ax is the sum of the products.
Statement F is true.
If a matrix A of order m x n and whose columns does not span [tex]$R^m$[/tex] , then equation [tex]$Ax=b$[/tex] will be inconsistent for any b in [tex]$R^m$[/tex] .
