Why would a box and whisker plot be unequal?

1 answer:

4 0

Becasue the data may be skewed right or left (not symmetrical)

that is obvious when the median lean to left or right while the maximum and minimum records are still as they are.

A coin is tossed 15 times. Find the probability of tossing seven or eight heads.

Mamont248 [21]

We will use Binomial Distribution in this case.

Since the coin is tossed 15 times. N which is the number of trails will be 15.

P = Probability of heads

Q = Probability of tails

X = No. heads occurring in each toss.

So, now we have to find the probability for exactly 10 heads.

P(x = 10) = C(15, 10) P^x Q^N-x

C(15, 10) (1/2)^10 (1/2)^5 = 0.0916

A firm produces two types of earphones per year: x thousand of type A and y thousand of type B. The cost function (in thousands

tino4ka555 [31]

Answer:

9000 A and 7000 B should be produced
p = 100, q = 170
$350,000 is the maximum profit

Step-by-step explanation:

We assume that "p" and "q" are given in dollars, so that the profit function (in thousands of dollars) can be written:

P = xp +yq -C(x, y)

Profit will be maximized when the partial derivatives of P with respect to x and y are both zero:

∂P/∂x = p +x(∂p/∂x) +y(∂q/∂x) -∂C/∂x = 0

(120 -3x +y) +x(-3) +y(1) -80 = 0

-6x +2y +40 = 0

3x -y = 20 . . . . put in standard form

and ...

∂P/∂y = x(∂p/∂y) +q +y(∂q/∂y) -∂C/∂y = 0

x(1) +(210 +x -7y) +y(-7) -(130) = 0

2x -14y +80 = 0

x -7y = -40 . . . . put in standard form

The solution to these simultaneous equations can be found a variety of ways. Using Cramer's Rule, we have ...

x = ((-1)(-40) -(-7)(20))/(-1·1-(-7)(3)) = 180/20 = 9

y = (20(1) -(-40)(3))/20 = 140/20 = 7

9000 type A and 7000 type B earphones should be produced.

The corresponding selling prices are ...

p = 120 -3(9) +7 = 100

q = 210 +9 -7(7) = 170

The selling prices should be ...

p = $100, q = $170

The maximum profit is ...

P = xp +yq -C(x, y) = (9)(100) +(7)(170) -(110 +80(9) +130(7))

P = 9(100 -180) +7(170 -130) -110 = 180 +280 -110

P = 350

The maximum profit is $350,000.

The amount of money you have is $ 20864.521

<h3>Solution:</h3>

Given that you invested $15,000 dollars for 11 years at 3% annual interest compounded continuously.

To find: total amount of money

The compound interest formula for compounded continously is given as:

$A = p e^{rt}$

Where "p" is the principal

"r" is the rate of interest

"t" is the number of years

Here in this problem, p = 15000

t = 11 years

$r = 3 \% = \frac{3}{100} = 0.03$

Substituting the values in formula we get,

$A = 15000e^{0.03 \times 11}\\\\A = 15000e^{0.33}\\\\A = 15000 \times 1.390968\\\\A = 20864.521$

Thus the amount of money you have is $ 20864.521
