Area of square tiles = 16 ft²
Area of rectangular floor = 52 yards * 40 yards = 2080 yards²
Number of square tiles needed = Area of Rectangular floor / Area of square tiles
3feet = 1 yard
Number = 2080 yards² / 16 ft²
= 2080 * (3 ft)² / 16 ft² having substituted
= 2080 * 3² ft² / 16 ft²
= (2080 *9) / 16
= 1170
So 1170 tiles are needed.
Answer:
(0,−13),(1,−10),(2,−7)
Step-by-step explanation:
Answer:
1) 2/3, two triangle segments
2) 1/7, one triangle segment
3) 3/9, three triangle segments left
really, you could do this by subtracting the top number, the numerator, because these visual diagrams have the same bottom number, or denominator, but for now, just subtract the segments. hope this helps, good luck.
Answer:
0.11% probability that you must ask 20 people to find one person without a social networking site
Step-by-step explanation:
We have these following probabilities:
75% probability that a millenial has a profile in a social netwok site.
25% probability that a millenial does not have a profile in a social network site.
What is the probability that you must ask 20 people to find one person without a social networking site?
The first 19 people have a social network site, each with a 75% probability.
The 20th person does not have a profile, with a 25% probability.
So
0.11% probability that you must ask 20 people to find one person without a social networking site
