Answer:
you add all the values up on the dot plot and then you divide that number by how many dots are in the plot and that is your median.
--Answer--
1. acute
2. right
3. acute
4. obtuse
5. straight
--Explanation--
Acute angle = Greater than 0 °, Less than 90°
Right angle = 90°
Obtuse angle = Greater than 90°, less than 180°
Straight angle = 180°
Answer:
2,
Step-by-step explanation:
The vertex is the very highest or very lowest point. X coordinates are listed first, then Y.
Answer:
2/3 or 0.66 repeated
Step-by-step explanation:
Since 2022 is only divisible by 1,2,4, and 5, the probability of getting a number that is a divisor of 2020 is 4/6, simplified to 2/3 or %0.66.
The volume of a cylinder is given by the formula <em>V</em>=π<em>r</em>²<em>h</em>². In this instance, <em>r</em> is 4 and the height is 47-12 (the height of the cone at the bottom is 12 mm and the sand goes up to 47 mm on the top portion of the hourglass, including both the cone and cylinder) or 35 mm.
<em>V</em>=π(4²)(35)=560π mm³.
The volume of a cone is given by the formula <em>V</em>=1/3π<em>r</em>²<em>h</em>². In this instance, <em>r</em> is 4 and the height is 12 mm.
<em>V</em>=1/3π(4²)(12)=π(1/3)(12)(4²)=π(4)(4²)=64π mm³.
This gives a total volume of 560π+64π=624π mm³ of sand.
Since the sand goes down to the bottom at a rate of 10π mm³/second, it will take 624π/10π=62.4 seconds for the sand to all drain out.
