Answer: a(x) =
An easy way to find this is by going on a graphing website like desmos. You simply put all of the equations into desmos and it will automatically recognize them as exponential functions, quadratic functions, etc. Once you do this you can write out x = 3 to create a line to compare them all.
If you can't use a graphing site, then simply insert 3 for x in each equation.
c(x) = 3 + 5(3) + 22
27 + 15 + 22 = 64
j(x) = 12(3)
12 * 3 = 36
a(x) =
9 * 9 * 9 or 9^3 = 729
c(x) = 64
j(x) = 36
a(x) = 729
defective rate on the assembly line has gone up to 12% and the manager wants to know the
probability that a skid of 50 DVD players will contain at least 3 defective units.
a) Help Avery use the binomial distribution P(x)=, C.pqrs to answer this question
Answer:
0.9487
Step-by-step explanation:
a) The probability of having a defective product = p = 12% = 0.12
The probability of not having a defective product = q = 1 - p = 1 - 0.12 = 0.88
The number of DVD players = n = 50
X is the number of defective products.
The probability that a skid of 50 DVD players will contain at least 3 defective units = P(X ≥ 3) = 1 - P(X ≤ 2)
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
Using binomial:
P(X = 0) =
P(X = 1) =
P(X = 2) =
P(X ≤ 2)= 0.0017 + 0.0114 + 0.0382 = 0.0513
P(X ≥ 3) = 1 - P(X ≤ 2) = 1 - 0.0513 = 0.9487 = 94.87%

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.
The statement that best describes the experimental probability of getting heads is:
It is 10% higher than the theoretical probability.
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
Answer:
32.45%
Step-by-step explanation:
To find the buying price as a percent of the selling price, we need to calculate the profit margin as a decimal first:
Profit margin = Selling price - Buying price
Profit margin = $59.95 - $40.50
Profit margin = $19.45
Now we can find the percent by dividing the profit margin by the selling price and multiplying by 100:
Percent = (Profit margin ÷ Selling price) x 100
Percent = ($19.45 / $59.95) x 100
Percent = 32.45%
Therefore, the buying price is 32.45% of the selling price.
Answer:
B) UY
Step-by-step explanation:
From the given figure, TUYX is one of the side of the rectangular prism and UVYZ is another side of the rectangular prism.
The both sides are intersecting perpendicular in one edge, that is the line segment UY.
You can see it on the figure.
Therefore, the intersecting line is UY.
Answer: B) UY
