Out of 18 people in a room, 2 have red hair. What is the probability that a person picked at random from the room does NOT have red hair?
Give an explanation plz:)
Answer :
Total number of people in the room = 18Number of people with red hair = 2Number of people not with red hair = 18 - 2 = 16Probability of picking a person who doesn't have red hair = [tex]\sf\dfrac{Number\:of\:favourable\:outcomes}{Total\:outcomes}[/tex]Probability = 16/18
Reduce the fraction with 2
Probability = 8/9
Answer:
[tex]\implies\boxed{\red{\sf P( not \ having\ red\ hair)=\dfrac{ 8}{9}}}[/tex]
Step-by-step explanation:
Given :-
There are 18 people in the room .Two of them have Red hair.And we need to find the probability that a person picked at random from the room does not have red hair . So for that firstly let us find how many people do not have red hair.
According to Question :-
[tex]\implies n_{(red)}+ n_{(not\ red)}= 18 \\\\\implies 2 + n_{(not\ red)}= 18 \\\\\implies n_{(not\ red)}= 18 -2 =\boxed{\red{16}}[/tex]
Hence the probability is :-
[tex]\implies P( not \ having\ red\ hair)=\dfrac{ n_{(favourable\ outcomes)}}{n_{(possible\ outcomes)}} \\\\\implies P( not \ having\ red\ hair)=\dfrac{ 16}{18} \\\\\implies\boxed{P( not \ having\ red\ hair)=\dfrac{ 8}{9}}[/tex]
Hence the required probability is 8/9 .

What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Given AB= 22 units
BC=16 units
AC=12 units
The property of Triangle says, in a triangle, angle opposite to the greater side have greater angle.
That is angle opposite to the shorter side have shorter angle.
Therefore, we have
Therefore,
angle opposite to side AC is angle B,
angle opposite to side BC is angle A,
angle opposite to side AB is angle C,
Therefore, the sequence from the smallest to the largest is angle B, angle A, angle C .

What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2
12x + 32 = 4
Given:
The equation is:
[tex]x^2-12x+32=4[/tex]
To find:
The result of completing the square for the given equation.
Solution:
We have,
[tex]x^2-12x+32=4[/tex]
It can be written as:
[tex]x^2-12x=4-32[/tex]
[tex]x^2-12x=-28[/tex]
Now, we need to add half of square of coefficient of x, to complete the square.
Adding [tex](\dfrac{-12}{2})^2[/tex] on both sides, we get
[tex]x^2-12x+(\dfrac{-12}{2})^2=-28+(\dfrac{-12}{2})^2[/tex]
[tex]x^2-2(x)(6)+(-6)^2=-28+(-6)^2[/tex]
[tex]x^2-2(x)(6)+(6)^2=-28+36[/tex] [tex][\because (-a)^2=(a)^2][/tex]
Using the formula [tex](a-b)^2=a^2-2ab+b^2[/tex], we get
[tex](x-6)^2=8[/tex]
Therefore, the required equation after completing the square is [tex](x-6)^2=8[/tex].

If two points known on the line A B in the coordinate plane is (7,15) and (18,42), calculate the slope of the line AB and the length of the line AB
Answer:
Slope = 27/11
AB = 29.15 u
Step-by-step explanation:
Given :-
Two points are given to us .The points are A(7,15) and B(18,42)To Find :-
The slope of the line .The length of line AB .We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,
[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]
Plug in the respective values ,[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]
Hence the slope of the line is 27/11 .
[tex]\rule{200}2[/tex]
Finding the length of AB :-
We can find the distance between them by using the Distance Formula .[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]
Hence the length of AB is 29.15 units .

Find the volume of the rectangular pyramid
Thank you!!
Answer:

Step-by-step explanation:
Please help! I don't really understand this.
Step-by-step explanation:
11.
Area of rectangle = 408 in²
Length = 3x-2 and width = x
The area of a rectangle is given by :
A = lb
(3x-2)x = 408
x = 12 inch and x = -11.33 in
Neglecting negative value,
The width of rectangle = 12 inch
The length of rectangle = 3x-2 = 3(12)-2 = 34 inch
12.
Base of triangle = 2x+2
Height = x
The area of a triangle is given by :
[tex]A=\dfrac{1}{2}bh\\\\600=\dfrac{1}{2}\times (2x+2)x\\\\600=(x+1)x[/tex]
x = 24 cm and x = -25 cm
Neglecting negative value, x = 24 cm
Base = 2x+2 = 2(24)+2 = 50 cm
Hence, this is the required solution.
soccer ball inflation:
How many pumps will it take to fill the large soccer ball with a circumference of 71 inches? Recall that the amount of air in one pump was about 11 cubic inches.
must show all work and justify work
Answer:
549 pumps
Step-by-step explanation:
We'll begin by calculating the radius of the larger ball. This can be obtained as follow:
Circumference (C) = 71
Pi (π) = 3.14
Radius (r) =?
C = 2πr
71 = 2 × 3.14 × r
71 = 6.28 × r
Divide both side by 6.28
r = 71 / 6.28
r = 11.3 in
Next, we shall determine the volume of the larger ball.
Since a ball is spherical in shape, we shall use the formula for calculating the volume of a sphere to obtain the volume of the ball. This can be obtained as follow:
Pi (π) = 3.14
Radius (r) = 11.3 in
Volume (V) =?
V = 4/3πr³
V = 4/3 × 3.14 × 11.3³
V = 4/3 × 3.14 × 1442.897
V = 6041 in³
Finally, we shall determine the number of pumps will it take to fill the large soccer ball. This can be obtained as follow:
11 in³ = 1 pump
Therefore,
6041 in³ = 6041 in³ × 1 pump / 11 in³
6041 in³ = 549 pumps
Thus, it will take approximately 549 pumps of air to fill the large soccer ball.

HELPPPP PLEASE HELP ME WITH BASIC MATH I REALLY APPRECIATE IT ((WILL MARK AS BRAINLIEST))
Answer:
3) 522
4) 468
Step-by-step explanation:
hello!
3) in the question, it says the cross section is a square, and the area of PQRS is 81.
for the square, we know that the length and height have to be the same, so if the area is 81, then we know the sides are both 9 because 9*9 is 81 and they're the same numbers multiplied. (same height and length)
with the information that all 4 sides of the square is 9 and the other side is labeled 10, we can figure out the rest.
both squares : 81+81=162
both 10 by 9 sides: 90+90=180
both 10 by 9 sides (top and bottom): 90+90=180
total surface area=162+180+180=522
4) for this problem, we can see that the triangle is a right triangle.
to solve the area of the triangle, we can do (9*12)/2=108/2=54.
there are two sides with triangles, so we double 54 (54*2=108)
9 by 10 side: 90
10 by 12 side: 120
now for the last slide, theres no information on the length. the formula for the diagonal is
a^2+b^2=c^2
which is
9^2+12^2=81+144=255=15^2
with this, the area of the rectangular side gives us 10*15 which is 150.
adding it together, we get
108+90+120+150=468.
hope this helps!
