Answer:A. The theoretical probability for pink is 95/185 or about 51.35%
B. The theoretical probability for brown is 90/185 or about 47.82%.
C. To find the experimental probability, we will make another fraction. The number of outcomes will be the numerator and the total will be the denominator.
Pink 36/69 = 52.17%
Brown 33/69 = 47.82%

Exercise 2: Calculate the height at which the kite is flying. Approach the height to the nearest integer. Show your work.
plz, help its Pythagorean Tioerm or however you spell it.
Answer:
Exercise 1:
base [b]=8cm
perpendicular [p]=6cm
hypotenuse [h]=?
By using Pythagoras law
h²=p²+b²
h²=6²+8²
h=√100
h=10cm
So another side's length is 10cm
Exercise 2:
base [b]=6m
perpendicular [p]=bm
hypotenuse [h]=8m
By using Pythagoras law
h²=p²+b²
8²=b²+6²
b²=8²-6²
b=√28=2√7 0r 5.29 or 5.3
So height of kite is√28or 2√7 0r 5.29 or 5.3 m

Find the area of AABC.
If entering your answer as a decimal, round your final answer to the nearest hundredth.
Square units
Answer:
Solution given:
AD=1.8
AC=3.0
we have
∆ADC is a right angled triangle
Cos A=b/h
<A=cos-¹ (1.8/3)
<A=53.13°
again
∆ABC is a right angled triangle
Tan A=p/b=BC/AC
Tan 53.13×3=BC
BC=4
NOW
Area of triangle =½(AC*BC)=½(4×3)=6 square units is a required area.
The area of triangle ABC is 6 square units.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
From triangle ADC, We find the side CD by using pythagoras theorem.
AD²+CD²=3²
1.8²+CD²=9
3.24+CD²=9
Subtract 3.24 from both sides
CD²=9-3.24
CD²=5.76
CD=2.4
Triangle ACD is similar to triangle ACB
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
AC/CD=AB/AC
3/1.8=AB/3
AB=9/1.8
=5
Area of triangle ABC= 1/2. AB.CD
=1/2×5×2.4
=6
Hence, the area of triangle ABC is 6 square units.

Step-by-step explanation:
Travis used 76% of the money in his savings account to buy something that cost him $380. How much money is left in his savings account?
Answer:
$120
Step-by-step explanation:
Step 1: Find how much he had in total. One way of doing that is setting up a fraction, then solve
[tex]\frac{76\%\:}{380}=\frac{100\%\:}{x}[/tex]
[tex]76\% =\frac{19}{25}[/tex]
[tex]100 =1[/tex]
Cross Multiply
[tex]\frac{19}{25}x=380\cdot \:1[/tex]
SImplify
[tex]\frac{19}{25}x=380[/tex]
Multiply both sides by 25
[tex]\frac{19}{25}x\cdot \:25=380\cdot \:25[/tex]
Simplify
[tex]19x=9500[/tex]
Divide both sides by 19
[tex]\frac{19x}{19}=\frac{9500}{19}[/tex]
Simplify
[tex]x=500[/tex]
That means he had a total of $500 in his account.
Step 2: Subtract the amount used from the total
[tex]500 - 380\\\\= 120[/tex]
Therefore, $120 is left in Travis' savings account.Answer:
$120
Step-by-step explanation:
Before the purchase, the amount of money in the account was x.
76% of the amount of money in the account is $380.
We write the above statement as an equation and solve for x, the original amount of money in the account.
76% of x = 380
0.76x = 380
Divide both sides by 0.76
0.76x/0.76 = 380/0.76
x = 500
He had $500 in his account.
He spent $380.
$500 - $380 = $120
He has $120 left in the account.

x = 82
Answer:
x = [tex]\frac{16}{\sqrt{2} }[/tex] and y = [tex]\frac{16}{\sqrt{2} }[/tex]
Step-by-step explanation:
Applying the trigonometric functions to the given triangle;
i. To determine the value of x;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Sin 45 = [tex]\frac{x}{16}[/tex]
x = 16 * Sin 45
= 16 * [tex]\frac{1}{\sqrt{2} }[/tex]
x = [tex]\frac{16}{\sqrt{2} }[/tex]
ii. To determine the value of y;
Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]
Cos 45 = [tex]\frac{y}{16}[/tex]
y = 16 * Cos 45
= 16 * [tex]\frac{1}{\sqrt{2} }[/tex]
y = [tex]\frac{16}{\sqrt{2} }[/tex]
Thus, x = [tex]\frac{16}{\sqrt{2} }[/tex] and y = [tex]\frac{16}{\sqrt{2} }[/tex]

The height of the square pyramid is 24 unit.Step-by-step explanation:
Given that:
Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unitTo Find:
The height of the square pyramid.We know that:
In pythagoras theorem.
H² = P² + B²Where,
H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unitFinding the height of the square pyramid:
⇒ H² = P² + B²
⇒ (25)² = x² + (7)²
⇒ 625 = x² + 49
⇒ x² = 625 - 49
⇒ x² = 576
⇒ x = √576
⇒ x = 24
Hence,
The height of the square pyramid = 24 unitYou sold your friend a raffle ticket for $1. If his ticket is selected from the 1000 sold, he will win
