The range rule of thumb roughly estimates the standard deviation of a data set as _______.

1 answer:

5 0

Range is the measure of variation that is very sensitive to extreme values. It is the difference between high and low values, while standard deviation is the standard measure of variation.The range rule of thumb roughly estimates the standard deviation of a data set as s=range/4 , where s stands for standard deviation and
range = Maximum - Minimum

You must pick one of two wagers, for an outcome based on flipping a fair coin. 1. You win $440 if it comes up heads and lose

UkoKoshka [18]

Answer:

See Below

Explanation:

Expected value is the sum of the products of the probability and payoff of each.

Wager 1:

probability of heads and tails, both is 0.5

Win = 440

Loose = 110

So,

Expected Value = 440(0.5) + (-110)(0.5) = 220 - 55 = $165

Wager 2:

Similar to wager 1

Win = 770

Loose = 220

So,

Expected value = 770(0.5) + (-220)(0.5) = 385 - 110 = $275

2nd wager is better, in this sense.

For the following transaction, determine whether cash flows from operating activities will increase, decrease, or remain the sam

grandymaker [24]

In case collected cash from a customer is for services that will be performed in the next accounting period the cash flow from operating activities will increase.

The cash flow from operating activities will increase cash flow in the period of receipt itself as it will result in an increase in the cash balance of the organization In case collected cash from a customer is for services that will be performed in the next accounting period.

If the balance of an asset will increase, cash float from operations will be lower. If the stability of an asset decreases, cash flow from operations will boom. If the balance of liability will increase, cash flows with the flow from operations will grow. If the balance of a liability decreases, cash flows with the flow from operations will decrease.

An accounting period, in bookkeeping, is the length with reference to which control accounts and economic statements are organized. In management accounting, the accounting length varies extensively and is decided with the aid of management. monthly accounting durations are common.

Let $S$ be the set of complex numbers of the form $a + bi,$ where $a$ and $b$ are integers. We say that $z \in S$ is a unit if t

lakkis [162]

Answer:

Number of units possible in S are 4.

Explanation:

Given S is a set of complex number of the form $a+bi$ where a and b are integers.

$z\in S$ is a unit if $w\in z$ exists such that $zw=1$ .

To find:

Number of units possible = ?

Solution:

Given that:

$zw = 1$

Taking modulus both sides:

$|zw| = |1|$

Using the property that modulus of product of two complex numbers is equal to their individual modulus multiplied.

i.e.

$|z_1z_2|=|z_1|.|z_2|$

So,

$|zw| = |1|\\\Rightarrow |zw| =|z|.|w| =1\\\Rightarrow |z|=\dfrac{1}{|w|}$ ......... (1)

Let $z=a+bi$

Then modulus of z is $|z| = \sqrt{a^2+b^2}$

Given that a and b are integers, so the equation (1) can be true only when $|z| = |w| =1$ (Reciprocal of 1 is 1). Modulus can be equal only when one of the following is satisfied:

(a = 1, b = 0) , (a = -1, b = 0), (a = 0, b = 1) OR (a = 0, b = -1)

So, the possible complex numbers can be:

$1.\ 1 + 0i = 1\\2.\ -1 + 0i = -1\\3.\ 0+ 1i = i\\4.\ 0 -1i = -i$

Hence, number of units possible in S are 4.
