for selling magazines jenng is paid 15% commission of the tot sales if she recivied $14.88 one week what were her total sales​

Answer:

(a) The probability that more than three arrive in one hour is approximately 0.018988

(b) The probability that no interval contains more than 3 arrivals in 30 separate one-hour intervals is approximately 0.56264

(c) The length of time such that the probability of no arrival is 0.1 is approximately 2.30259 hours

Step-by-step explanation:

The distribution of the arrival time of a small aircraft = Exponential distribution

The mean arrival time, μ = 1 hour

The pdf of a exponential distribution, f(x) = λ·e^(-λ·x)

The mean, μ = 1/λ

∴ 1 = 1/λ

λ = 1 hour

∴ For the exponential distribution, f(x) = 1·e^(-x)

(a) The Poisson probability is given as follows;

[tex]P(X = k) = \dfrac{\lambda^k \times e^{-k}}{k!}[/tex]

The probability for more than 3 is given as follows;

[tex]P(X > 3) = 1 - \dfrac{1^0 \times e^{-1}}{0!} - \dfrac{1^1 \times e^{-1}}{1!} - \dfrac{1^2 \times e^{-1}}{2!} - \dfrac{1^3 \times e^{-1}}{3!} \approx 0.018988[/tex]

(b) P(X ≤ 3) for 30 1 hour intervals = P(X ≤ 3)³⁰ = (1 - 0.018988)³⁰ ≈ 0.56264

(c) When the probability that no arrival occurs is 0.1, we have;

0.1 P(X > x) = f(x) = 1·e^(-x) = e^(-x)

-x·ln(e) = ln(0.1)

∴ x = -㏑(0.1) ≈ 2.30259

The length of time such that the probability that no arrival occur during the interval is 0.1, x ≈ 2.30259 hours.

Answer:

$50

Step-by-step explanation:

Given data

Let the total purchase be x

Hence 30% of x is $15

Let us find the value of x

30/100*x= 15

0.3*x=15

0.3x=15

x= 15/0.3

x= $50

Hence the purchase is $50

Answer:

$50 is the total

Step-by-step explanation:

30% over 100% =  15 over x

then you cross multiply and get:

30x = 1500

you then divide both sides by 30

30 and 30 cross out

1500 ÷ 30 = $50

Answer:

-2+4i

Step-by-step explanation:

Simplify by combining the real and imaginary parts of each expression.

The simplified form of the complex expression is -2 + 4i.

Complex numbers are numbers which are of the form [tex]a+ib[/tex],

where a and b are real numbers and i is the imaginary number called iota whose value is [tex]i^{2}[/tex] = -1.

Given expression is (2 + 3i) + (-4 + i).

Addition of complex numbers is defined as,

(a + ib) + (a' + ib') = (a + a') + i(b + b')

Using the definition of addition of complex numbers, given expression can be added as,

(2 + 3i) + (-4 + i) = (2 + -4) + i(3 + 1) = -2 + 4i

Hence the resulting value is -2 + 4i.

Answer:

C.) 87 years

Step-by-step explanation:

I've taken the test! Hope this helps! ;)

The number of years for her to have at least $100,000 if interest is compounded continuously is 90

The given parameters are:

Amount, A = 100,000

Principal, P = 100

Rate, r = 8%

Amount is calculated using:

A = P * (1 + r)^t

So, we have:

100000 = 100 * (1 + 8%)^t

Divide by 100

1000 = (1 + 8%)^t

Evaluate the sum

1000 = 1.08^t

Take the logarithm of both sides

log(1000) = log(1.08)^t

Apply the law of logarithm

log(1000) = tlog(1.08)

Solve for t

t = log(1000)/log(1.08)

Divide

t = 89.7

Approximate

t = 90

Hence, the number of years is 90

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Your plan for your T-shirt business calls for you to be able to produce 60,000 screen printed shirts in a month.

And, Each screen press can handle 500 shirts per day.

Now,

Since, In a month there are 30 days.

And, Your plan for your T-shirt business calls for you to be able to produce 60,000 screen printed shirts in a month.

Hence, Number of shirts need to press per day = 60,000 / 30

                                                                          = 2,000

Since, Each screen press can handle 500 shirts per day.

Hence, Number of press for 2,000 shirts = 2,000 / 500

                                                                = 4

Thus, There are 4 presses we need.
