An art classroom has 5 boxes with sharpie pens and clipboards. Each box has 4 sharpies there are 25 supplies in all how many tot

Step2247 [10]

Answer:

1 clipboard per box

Step-by-step explanation:

First, multiply 4 by 5 (because we need to see how many supplies there are already taken up)

4x5= 20

Next, subtract 25 from 20 (to see how many total clipboards there are)

25-20= 5

Since there are 5 boxes, we divide the number of clipboards(5) by the number boxes(5):

5/5= 1

the terms in sequence A increases by 3. The terms in sequence B increase by 8. In which sequence do the terms form a steeper lin

il63 [147K]

Solution: The sequence B shows the steeper line.

Exanation:

The line having greater slope is always steeper than the other lines.

Since it is given that the sequence A increases by 3 and the sequence B increases by 8. It means for each additional value the sequences increased by 3 and 5 units respectively.

The slope of line is rate of change of one variable with respect to another variable.

The sequence A increased by 3, therefore the slope of line of sequence A is 3.

The sequence B increased by 8, therefore the slope of line of sequence B is 8.

Since the slope of sequence B is greater than the slope of sequence A, therefore the line of sequence B is steeper than the line of sequence A.

The sequence A can be defined as 3,6,9,12,.... and the sequence B can be defined as 8,16,24,....

So the coordinates points of sequence A are (0,0)(1,3),(2,6) and the coordinates points of sequence B are (0,0),(1,8),(2,16).

From the given figure it is notes that the blue line is steeper than red line.

Therefore, the sequence B shows the steeper line.

Answer:

Given that a person was identified as a future terrorist, there is a 2.8544% probability that he/she actually is a future terrorist.

Step-by-step explanation:

There are 1000 future terrorists in a population of 300,000,000. So the probability that a randomly selected person in this population is a terrorist is:

$P = \frac{1,000}{300,000,000} = 0.000003 = 0.0003%$

So, we have these following probabilities:

A 99.9997% probability that a randomly chosen person is not a terrorist.

A 0.0003% probability that a randomly chosen person is a terrorist.

A 98% probability that a future terrorist is correctly identified

A 99.9% chance of correctly identifying someone who is not a future terrorist. This also means that there is a 0.01% probability of someone who is not a terrorist being identified as one.

This can be formulated as the following problem:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

$P = \frac{P(B).P(A/B)}{P(A)}$

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

Here we have:

What is the probability that the person is a terrorist, given that she was identified as a terrorist.

P(B) is the probability that the person is a terrorist. So $P(B) = 0.000003$

P(A/B) is the probability that the person was identified as a terrorist, given that she is a terrorist. The problem states that the system has a 98% chance of correctly identifying a future terrorist, so $P(A/B) = 0.98$
