Answer:
The experimental probability --> [tex]\frac{13}{20}[/tex]
The theoretical probability --> [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Key skills needed: Experimental vs theoretical probability, Fractions
1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)
- Theoretical probability is based on simple reasoning
- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)
2) Now with this, let's start solving:
Experimental probability ---> [tex]\frac{heads}{total}[/tex] --> You flipped the coin a total of 100 times, so the denominator would be 100. 65 of those would be heads so 65 is our numerator. So our experimental probability is --> [tex]\frac{65}{100}[/tex] --> Both have the factor of 5, so take the factor of 5 out of the numerator and denominator and you will get --> [tex]\frac{13}{20}[/tex] Now onto theoretical probability --> [tex]\frac{heads}{total}[/tex] --> There are 2 faces of a coin, 1 side is heads, and 1 side is tails --> The total number of faces is 2, so 2 is our denominator. There is only 1 side that is heads, so 1 is the numerator. This means --> Our theoretical probability is [tex]\frac{1}{2}[/tex]Hope you understood and have a nice day!! :D
Answer:
Experimental Probability: 65/100 We tested the probability 100 times, 65 of those times being heads. So %65 is our experimental probability (in percentage form) of flipping a coin and landing on heads. Simplified, 13/20 is our fraction.
Theoretical Probability: 50/100 or 1/2. There are two sides to a coin, and one is heads, so the theoretical probability is 1/2. In percentage form, the probability would be %50, or 50/100.
Find the value of x PLS ANSWER THIS ASAP I WILL MARK THE BRAINIEST
Answer:
Answer: B. x=7
Step-by-step explanation:
Similar Triangles
Assuming the up arrows indicate parallel lines, then triangles PQT and PRS are similar. See the image provided below.
Similar triangles have their side lengths proportional by a constant scale factor. They also have all of their internal angles congruent, or with the same measure.
This means that the marked angles are equal:
2x + 5 = x + 12
Subtracting x
x + 5 = 12
Subtracting 5:
x = 7
Answer: B. x=7

5/8 is greater then 7/12.
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 8 and 12 is 24
For the 1st fraction, since 8 × 3 = 24,
5/8=5x3/8x3=15/24
Likewise, for the 2nd fraction, since 12 × 2 = 24,
7/12= 7x2/12x2=14/24
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
15/24>14/24 or 5/8>7/12
find the missing angle in the picture below. please help!:)
Answer:
24°
Step-by-step explanation:
Let's represent the unknown angle with x
So ;
66+x=90
x=90-66
x=24°
Therefore 24° is the missing angle.
Answer:
24°
Step-by-step explanation:
The missing angle is 90-66 = 24°.

Bridget is 5 years older than Angad. Paul is 4 years younger than Angad. If the total of their
ages is 49, how old is the eldest of them?
Answer: Bridge is 21 years old
Step-by-step explanation:
Ok so after reading the question I already know that B (Bridget), A (Angad) and P (Paul) is 49 in the sum of age. I also know that B=A+5 and P=A-4. After that I can assume B=P+5+4. So now after we gather everything, the age of all of them is the same if we delete 5, 4, 4 (From B=P+5+4 and P=A-4). 49-5-4-4=36. So now lets assume they are all 12 (36/3=12). B is 5 years older so lets add 5 to B. B=17, A=12 and P=8. 8+12+17= 37. We now know that but 37 is 12 under 49, so lets add the average 12/3=4 so we add 4 to all of them. B=21 A=16 P=12. 21+16+12=49. So Bridge is 21 years old, Angad is 16 years old and Paul is 12 years old

The pressure P of a gas varies inversely as its
volume V and directly as the temperature T. A
certain gas has a pressure of 2.7 atm, a
volume of 3.6 L, and a temperature of 324 K.
If the volume of the gas is kept constant and
the temperature is increased to 396 K, what
will the new pressure be?
Answer:
The new pressure P₂ is 3.3 atm
Step-by-step explanation:
Pressure of gas = 2.7 atm
Volume = 3.6 L
Temperature = 324 K
Now we are given that volume of the gas is kept constant.
Temperature is increased to 396 K
We need to find the pressure.
The formula used is: [tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]
We have P₁ = 2.7
T₁ = 324 K
T₂ = 396 K
P₂ = ?
Putting values in the formula and finding P₂
[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}\\\frac{2.7}{324}=\frac{P_2}{396}\\P_2=\frac{2.7}{324}\times 396\\P_2=0.0083 \times 396\\P_2=3.3[/tex]
So, the new pressure P₂ is 3.3 atm

Company A rents a bounce house for $100 rental fee plus $20 per hour. Company B rents a bounce house for $40 per hour . Let h=the number of hours the bounce house is rented.Write an expression that shows the cost of renting a bounce house from each company
Answer:
A= 100+20h B=40h
Step-by-step explanation:
A=100+20h
B= 40h
Answer:
For company A:
100 + (20h)
OR
100 + (20 x h)
For company B:
40h
OR
40 x h
Step-by-step explanation:
For company A, you are multiplying 20 by h because you must pay $20 per hour. Then, you have to add 100 to that because there is a $100 dollar rental fee.
For company B, you are multiplying 40 by h because you must pay $40 per hour. There is no rental fee, so that means you don't have to add anything.
Hope this helps!
