Answer:
3/10
Step-by-step explanation:
<em>Step 1 : Write the formula of calculating probability</em>
Probability = Number of favourable outcomes/Number of total outcomes
<em>Step 2 : Identify the favourable (requires) outcomes and the total outcomes</em>
- Total outcomes are the total cards that are placed on the table = 10 cards
- The favourable outcomes are the number of cards that have an even number on them.
12, 14, 18 = 3 cards
<em>Step 3 : Substitute the values in the formula</em>
Probability = Number of favourable outcomes/Number of total outcomes
Probability = 3/10
Therefore, the probability of picking a card with and even number is 3/10.

Answer: 40.5 square feet
Step-by-step explanation:
Given : Zhi needs new flooring for her two laundry rooms.each room is 4.5 feet long and 4.5 feet wide .
We assume that the room is rectangular in shape .
Area of rectangle = Length x width
Then area of one laundry room = 4.5 feet x 4.5 feet = 20.25 square feet
Area of two laundry room = 2 x 20.25 = 40.5 square feet.
Hence, The flooring need to cover a total of <u>40.5 square feet</u> of area.
Answer:
y = - 13, y = 13
Step-by-step explanation:
Given
y² = 169 ( take the square root of both sides )
y = ± 
= ± 13
Since 13 × 13 = 169 and - 13 × - 13 = 169
