Step-by-step explanation:

A 1 / A 2 = B2 / B1

4 / A 2 = - 72 / 9

A 2 = - I / 2

Let A = any rational number is the absolute value of a different if A is a positive number or negative number Explain

artcher [175]

Absolute value is always positive because its talking about the real distance or steps to zero and even when you at a negative number it takes real steps to get back to zero.

A spinner of a board game can land on any one of three regionslabeled: A, B, and C. If the probability the spinner lands on B

Veseljchak [2.6K]

Answer:

The probability of the spinner landing on A is 0.1111.

Step-by-step explanation:

The possible outcomes of a board game is that it can lead on any three of the regions, A, B and C.

The probability of all the outcomes of an event sums up to be 1.

$P(E) = P(E_{1})+P(E_{2})+...+P(E_{n})=1$

According to the provided information:

P (B) = 3 P (A)

P (C) = 5 P (A)

Compute the probability of the spinner landing on A as follows:

$P(A)+P(B)+P(C)=1\\P(A)+3P(A)+5P(A)=1\\9P(A)=1\\P(A)=\frac{1}{9}\\=0.111111\\\approx0.1111$

Thus, the probability of the spinner landing on A is 0.1111.

Based on a survey, assume that % of consumers are comfortable having drones deliver their purchases. Suppose that we want to f

n200080 [17]

Answer and Step-by-step explanation:

Solution:

Given:

Assume that 46% of consumers are comfortable to deliver their purchase.

Five consumers randomly selected.

Exactly three of them are comfortable with delivery by drones.

Identify the value of n, x, p?

Probability of success on any one trial = 46% = 0.46

Probability of failure on any trial = q = 1-p

= 1- 0.46

= 0.54

The number of trial = n = 5

The number of comfortable consumers =x = 3

n represent the number of subject included.in this question, there are five consumers randomly selected.

X represents the number of success. In question, there are exactly three consumers that are comfortable with delivery by drones.

P represents the probability of success, and q represent the probability of failure.

Hence,

n = 5

x= 3

p = 0.46

q= 0.54
