Which of the following functions has the largest value when x = 3? (1 point)c(x) = 3x2 + 5x + 22
j(x) = 12x
a(x) = 9x


All the functions are equal at x = 3.
c(x)
j(x)
a(x)

Answers

Answer 1
Answer: x = 3

c(x) = 3x² + 5x + 22 
⇒ c(3) = 3(3²) + 5(3) + 22 
⇒ c(3) = 3(9) + 15 + 22
⇒ c(3) = 27 + 15 + 22
⇒ c(3) = 64

j(x) = 12x
⇒ j(3) = 12(3)
⇒ j(3) = 36

a(x) = 9x
⇒ a(3) = 9(3)
⇒ a(3) = 27

c(x) = 3x² + 5x + 22 is the function that has the largest value when x = 3.

False. Not all functions are equal at x = 3.
Answer 2
Answer:

Answer: a(x) = 9^(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(3)^(2) + 5(3) + 22

27 + 15 + 22 = 64

j(x) = 12(3)

12 * 3 = 36

a(x) = 9^((3))

9 * 9 * 9 or 9^3 = 729

c(x) = 64

j(x) = 36

a(x) = 729

MDM4U11. Avery and Bradley work at a large electronics manufacturer that produces DVD players. The
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

Answers

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) = C(n,x)p^xq^(n-x)=C(50,0)p^0q^(50-0)=(50!)/((50-0)!0!)*0.12^0*0.88^(50-0)=0.0017

P(X = 1) = C(n,x)p^xq^(n-x)=C(50,1)p^1q^(50-1)=(50!)/((50-1)!1!)*0.12^1*0.88^(50-1)=0.0114

P(X = 2) = C(n,x)p^xq^(n-x)=C(50,2)p^2q^(50-2)=(50!)/((50-2)!2!)*0.12^2*0.88^(50-2)=0.0382

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%

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:

(0.6-0.5)* 100\n\n\n=(0.1)* 100\n\n=10\%

Answer:

Its 10% higher than theoretical

Step-by-step explanation:

90/150 x 100= 60%

60-50=10

Amir owns and operates a clothing store. He sells a shirt for $59.95. He Originally bought the shirt for $40.50. What is the buying price as a percent of his selling price?

Answers

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.
