Answer:

The probability of getting a black pen from the bag is 13.5%.

Step-by-step explanation:

To determine the percentage probability that a black pen will be obtained from the bag, the following calculation must be performed:

12 + 20 + 5 = 37

37 = 100%

5 = X

(5 x 100) / 37 = X

500/37 = X

13.5 = X

Thus, it is determined that the totality of pens is 100%, and through a cross multiplication the percentage of the 5 black pens with respect to the total of pens is obtained.

Therefore, the probability of getting a black pen from the bag is 13.5%.

Explain how your knowledge of place value helps you divide a number in the thousands by whole numbers to ten . Give an example t

poizon [28]

Place value is the value individual digit has in its location: in order from higher to lower value, there is thousands, hundreds, tens, and ones.
When you divide by 10, you are affecting (only once) every digit from its current place value to the right.
For example 1000 divided by 10 = 100, you have relocated every digit to the right, making the zero dissolve (or better yet, divided by a hidden and in this case unusable comma).

MULTIPLE CHOICE A thermometer is

pav-90 [236]

The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F

Thermometer accuracy = ±2°F
Thermometer reading = 17°F

The least possible value of temperature can be calculated thus :

Thermometer reading - thermometer accuracy

17 - 2 = 15°F

The highest possible temperature can be calculated thus :

Themometer reading - thermometer accuracy

17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
