A coin was flipped 150 times. The results of the experiment are shown in the following table:Heads Tails
90 60
Which of the following best describes the experimental probability of getting heads?
It is 10% higher than the theoretical probability.
It is 10% lower than the theoretical probability.
It is equal to the theoretical probability for this data.
The experimental probability cannot be concluded from the data in the table.
Answers
Answer:
The statement that best describes the experimental probability of getting heads is:
It is 10% higher than the theoretical probability.
Step-by-step explanation:
We know that the theoretical probability of getting head is: 0.5
and the theoretical probability of getting tail is: 0.5
Also, the results of experiments are:
Heads Tails
90 60
This means that the experimental probability of getting head is: 90/150=3/5=0.6
and the experimental probability of getting tail is: 60/150=2/5=0.4
Hence, the experimental and theoretical probability of getting head is not same or equal.
Also, the experimental probability of getting head is more than the theoretical probability of getting head and the percent increase is calculated as:
Answer:
Its 10% higher than theoretical
Step-by-step explanation:
90/150 x 100= 60%
60-50=10

The distance of salmon from the surface of the water is 8 feet.
What are mathematical operations?
Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Given that,
The distance of school of salmon for the surface of the river = 5 feet.
Since, to escape a hungry bear, the school of salmon went down to 3 feet.
The position of the salmon to the surface = 5 + 3 = 8 feet.
The required distance of school of salmon from the surface of water is 8 feet.

Answer:
8 Feet below the surface
Step-by-step explanation:
If the salmon were initially 5 feet below the surface, and then travelled down an additional 3 feet from the initial 5, then the new position would be 8 feet down relative to the surface.
You can write this as -5 + -3 = -8, assuming that 0 represents surface level.
Cheers.

Answer:
The equation has two different real solutions
Step-by-step explanation:
The discriminant of the quadratic equation ax² + bx + c = 0 is Δ = b² - 4ac, it used to find the number and type of solutions
- Δ > 0, means two different real solutions
- Δ = 0, means one real solution
- Δ < 0, means no real solutions
∵ The equation is a² + 8a = 13
- Put it in the form ax² + bx + c = 0
- Subtract 13 from both sides
∴ a² + 8a - 13 = 0
∴ The coefficient of a² = 1, the coefficient of a = 8 and the
numerical term = -13
∵ Δ = (coefficient of a)² - 4(coefficient of a²)(numerical term)
∴ Δ = (8)² - 4(1)(-13)
∴ Δ = 64 + 52
∴ Δ = 116
∵ Δ > 0
∴ The equation has two different real solutions

Step-by-step explanation:
Given that the manager of a plant nursery bought 120 lb of soil to use for potting plants. the manager can put 5 lb into each of the small pots and 12 lb into each of the large pots.
Let no of 5 lbs pots be x and 12 lbs pots be y.
Then total no of weight of soil used will be
Hence
x intercept of this line is
y intercept of this line is
Hence correct answer is option b.
B=6p3 + 29p2 – 22p + 21
C=6p3 + 29p2 + 22p – 21
D=6p3 + 29p2 + 34p – 21
Answers
To calculate the product, we need to multiply each member of each multiplier:
(2p + 7)(3p2 + 4p – 3) = 2p · 3p² + 2p · 4p + 2p · -3 + 7 ·3p² + 7 · 4p + 7 · -3
= 6p³ + 8p² - 6p + 21p² + 28p - 21
= 6p³ + 8p² + 21p² + 28p - 6p -21
= 6p³ + 29p² + 22p - 21
Therefore, the product of (2p + 7)(3p2 + 4p – 3) is 6p³ + 29p² + 22p -21
