Answer:$12,800

Step-by-step explanation:

Add 400 to every n in the equation, I’ll be using y for the “p(n)” part cus it always confuses me like that.

Y=52(400)-0.05 x 400^2

=20,800 - 0.05 x 160,000

=20,800 - 8,000

=12,800

1. The mark up price of a pair of shoes which costs $125. 00 is 8. 35%. A)What is the final price? If the tax is 6 1/2% How much

Xelga [282]

Answer:

Step-by-step explanation:

Remark

The wholesale price of the shoes is 125 dollars

The retailer marks it uu to 35% more to the wholesale price.

So the price is now 125 + 35% * 125 dollars

That amount is 125 + 35/100 * 125 = 125 + 43.75 = 168.75

The government wants its cut of 6.5% of the selling price

So the final price is 168.75 + 168.75 * 6.5/100

The final price is 168.75 + 10.97 = 179.72

Answer: A customer pays 179.72 dollars.

Historical data for a local manufacturing company show that the average number of defects per product produced is 2. In addition

charle [14.2K]

Answer:

The probability that there will be a total of 7 defects on four units is 0.14.

Step-by-step explanation:

A Poisson distribution describes the probability distribution of number of success in a specified time interval.

The probability distribution function for a Poisson distribution is:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}, x=0,1,2,3,...$

Let <em>X</em> = number of defects in a unit produced.

It is provided that there are, on average, 2 defects per unit produced.

Then in 4 units the number of defects is, $(2\times4)=8$ .

Compute the probability of exactly 7 defects in 4 units as follows:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}\\P(X=7)=\frac{e^{-8}8^{7}}{7!}\\=\frac{0.0003355\times2097152}{5040}\\ =0.1396\\\approx0.14$

Thus, the probability of exactly 7 defects in 4 units is 0.14.

Witch of the s-values satisfy the following inequality?

levacccp [35]

Answer:

the possible answer would be A, 6.

Step-by-step explanation:

6/2 is equal to 3 wholes. 7 minus 3 is 4. the sign > is used to indicate that the left number is greater than the right number, which is 3. 4 > 3 would be shown. this means that 6, or A, is the answer! :)

(6 IS ALSO THE ONLY OPTION. I NOTICED IT SAYS “ALL ANSWERS“

hello

to solve this question, we need to use know the number of possible outcomes

$\begin{gathered} \text{probability = }\frac{nX}{nS} \\ S=\text{ number of possible outcomes} \\ X=\text{ number of events} \end{gathered}$

let's find the number of possible outcomes

we have four tiles numbered 1, 4, 5 and 8

possible outcomes are
