Answer:

0.4394

Step-by-step explanation:

given that an auto parts store is examining how many items were purchased per transaction at the store as compared to their online website

The data is shown below:

Frequency Frequency*Midpt

Midpt Online Total Online Total

1-3 2 40 147 80 294

4-6 5 60 103 300 515

7-9 8 15 32 120 256

10-12 11 5 18 55 198

120 300 555 1263

Thus we find total items purchased on line = 555

and total items overall purchased = 1263

Hence the probability that a randomly selected item was purchased online

= $\frac{555}{1263} \\=0.4394$

He logical statement represents the inverse of the conditional statement “if you are human, then you were born on earth.”

Artyom0805 [142]

The conditional statement “if you are human, then you were born on earth.”

The logical statement is the inverse of the conditional statement.

So, the logical statement is If you are born on earth then you are a human.

Now we can say that our conditional statement is absolutely true in all condition

which states If i am a human⇒ I am born on earth

but logical statement is not true because If i am born on earth it does not mean that i can be only human, i can be other creature also.

The answer can be depicted by venn diagram also.

Jaun rides the bus to school each day he always arrives at his bus stop on time but his bus is late 80% of the time

Yuri [45]

The correct probability that Juan's bus is going to be late every week next week is 20 percent.

<h3>How to solve for the probability</h3>

We have the total number in the stimulation on to be from 0 to 9

On the fact that it would be late, the number ranges from 2 to 9

Hence the fact that it would be late would be

2/10

= 0.2

0.2 is also the same as 20 percent.

<h3>Complete question</h3>

Juan rides the bus to school each day. He always arrives at his bus stop on time, but his bus is late 80% of the time. Juan runs a simulation to model this using a random number generator. He assigns these digits to the possible outcomes for each day of the week:

• Let 0 and 1 = bus is on time

• Let 2, 3, 4, 5, 6, 7, 8, and 9 = bus is late

The table shows the results of the simulation.
