A fair coin is tossed 30 times and 12 heads result. What is the relative frequency of obtaining a tails?
Answer:
You have a 60% chance if obtaining tails
Step-by-step explanation:
30-12=18
30x60%=18
18 times of obtaining tails means you have a 60% chance of obtaining tails

Can anyone solve this linear equation with elimination method? Please its important!
Please give the code :/
Step-by-step explanation:
1. m = (9-3)/(2-1) = 6/1 = 6 => B
2. m = (-7-5)/(2+1) = -12/3 = -4 => G
3. the horizontal line passes (0,4) => m = 0 =>I
4. m = (2-1)/(8-8) = 1/0 = oo => undefined => A

Find the area of each rectangle first
and then add the two areas together.
Answer:
44m²
Step-by-step explanation:
Area of larger rectangle
= length × breadth
= 8m × 4m
= 32m²
Area of smaller rectangle
= length × breadth
= 4m × 3m
= 12m²
Total area of the figure
= Area of larger rectangle + Area of smaller rectangle
= 32m² + 12m²
= 44m²
2. Show that a. the points 3 + i,6,4 + 4i are vertices of right triangle
Answer:
Step-by-step explanation:
[tex]Z_1=3+i\\Z_2=6\\Z_3=4+4i\\\\||Z_2\ Z_1||^2=||-3+i||^2=9+1=10\\\\||Z_1\ Z_3||^2=||1+3i||^2=10\\\\||Z_2\ Z_3||^2=||-2+4i||^2=20\\\\And\ 10+10=20[/tex]
Using the converse of the Pythagorean's theorem, the triangle is right.
Using Pythagorean theorem, the points 3 + i, 6, and 4 + 4i indeed form the vertices of a right triangle.
The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).
Let's calculate the distances between the points and then check if the Pythagorean theorem holds for them.
Distance between points A (3 + i) and B (6):
Distance AB = |6 - (3 + i)|
= |6 - 3 - i|
= |3 - i|
= [tex]\sqrt{(3^2 + (-1)^2)[/tex]
= √10
Distance between points A (3 + i) and C (4 + 4i):
Distance AC = |4 + 4i - (3 + i)|
= |1 + 3i|
= [tex]\sqrt{(1^2 + 3^2)[/tex]
= √10
Distance between points B (6) and C (4 + 4i):
Distance BC = |4 + 4i - 6|
= |-2 + 4i|
= [tex]\sqrt{((-2)^2 + 4^2)[/tex]
= √20
Now let's check if the Pythagorean theorem holds for these distances:
Longest side: [tex]BC^2 = (\sqrt20)^2 = 20[/tex]
Sum of squares of shorter sides:
[tex]AB^2 + AC^2 = (\sqrt10)^2 + (\sqrt10)^2[/tex] = 10 + 10 = 20
Since the sum of the squares of the shorter sides is equal to the square of the longest side.
So, the points 3 + i, 6, and 4 + 4i are vertices of a right triangle.

Find an equation for the line that passes through the points -4, -1 and 2, 3
Answer:
x1=-4,y1=-1,x2=2,y2=3
Now,
slope (m)=3/2
By formula,
(y-y1)=m (X-x1)
y-(-1)=3/2(x+4)
y+1=3/2(x+4)

solve |5-9|+2·3= help porfavor !! asap pls
Answer:
10
Step-by-step explanation:
|5-9|+2*3
lets use the P.E.M.D.A.S order of operations rule
we have no parenthesis or exponents, so we skip to multiplication
2*3=6
then we do addition/subtraction
since the subtraction sign comes first in the equation, we evaluate
5-9=-4
since the subtraction part is in the absolution value signs, we change -4 to its absolute value.
|-4|=4
now we are left with 4+6
add
4+6=10
so, |5-9|+2*3=10

On the planet Tott, there are 9 frenks to every 8 vreels. If farmer Yoy
has 80 frenks on her rew farm, how many vreels are on the farm?
Round to the nearest tenth if rounding is needed?
Answer:
71.1 vreels on the farm
Step-by-step explanation:
Create a proportion where x is how many vreels are on the farm:
[tex]\frac{9}{8}[/tex] = [tex]\frac{80}{x}[/tex]
Cross multiply and solve for x:
9x = 640
x = 71.1
So, to the nearest tenth, there are 71.1 vreels on the farm.

A bag contains three types of candy (gumdrops, jelly beans, and jawbreakers). If
chosen at random, the probability of getting a gumdrop is 1/6 and the probability
of getting a jellybean is 1/3 What is the probability of getting a jawbreaker?
Answer:
P) = 1/2 jawbreaker
simplified P) 3/6 = 1/2 jawbreaker
Which both mean the same, so show simplified if asked and either answer if not asked would be marked high.
as 2/6 + 1/3 = 3/6
1 - 3/6 = 3/6
= 1/2 are the workings.
Step-by-step explanation:
Jelly bean = 1/3 = 2/6
Gumdrop = 1/6
2/6 + 1/6 = 3/6 = the difference of 1
1-3/6 = 3/6
Therefore; P) = 3/6 jawbreaker

Answer:
y=-3/11x+67/11
Step-by-step explanation:
y-8=-5-8/4--7(x--7)
y-8=-3/11(x+7)
11y-88=-3x-21
11y=-3x-21+88
11y=-3x+67
y=-3/11x+67/11
Answer:
y = -13/11x - 3/11
Step-by-step explanation:
First, find the slope of the line using the slope formula.
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-5-8}{4-(-7)}\\m=-\frac{13}{11}[/tex]
Then, use the point-slope formula and substitute the values for the variables.
[tex]y-y_1=m(x-x_1)\\y-8=-\frac{13}{11}(x-(-7))\\y-8=-\frac{13}{11}x-\frac{91}{11}\\y=-\frac{13}{11}x-\frac{3}{11}[/tex]
