2.6\le2.6 classifies as \text{true}

-6 classifies as \text{false},

3.1>-3.1 classifies as \text{true}

so -5\ge -5 classifies as \text{true}

To classify the statements, we need to evaluate each of them:

\text{Evaluate }2.6\le2.6\\\implies (2.6

so 2.6\le2.6 classifies as \text{true}, since the statement also allows 2.6 to be equal to itself.

\text{Evaluate }-6

so -6 classifies as \text{false}, since -6 is equal to itself, not smaller.

\text{Evaluate }3.1>-3.1\\\implies \text{true}

so 3.1>-3.1 classifies as \text{true}, since x>-x, for all real numbers

\text{Evaluate }-5\ge-5\\\implies (-5>-5)\text{ or }(-5=-5)\\\implies \text{false  or  true}\\\implies\text{true}

so -5\ge -5 classifies as \text{true}, since the statement also allows -5 to be equal to itself.

14. A company uses many different delivery
ziro4ka [17]

Answer:

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Sent by ABC Speedy Delivery Service.

Event B: Arrived on time.

The probability that any given parcel will be sent by the ABC Speedy Delivery Service is 0.71.

This means that P(A) = 0.71

The probability that the parcel will arrive on time given the ABC Speedy Delivery Company was used is 0.93.

This means that P(B|A) = 0.93

Find the probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

This is P(A \cap B). So

P(B|A) = \frac{P(A \cap B)}{P(A)}

P(A \cap B) = P(B|A)*P(A) = 0.93*0.71 = 0.6603

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

Why are linear functions sometimes symmetric about the y-axis but never symmetric about the x-axis
lina2011 [118]
Test for symmetry about the x-axis: Replace y with (-y). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the x-axis. Example: Use the test for symmetry about the x-axis to determine if the graph of y - 5x2 = 4 is symmetric about the x-axis.
