Answer:
5 seconds
Step-by-step explanation:
The ground is 25 eet, so 25=-16t^2+400
-16t^2=-400, 16t^2=400
t^2=25, dividing both sides by 16
t=5 seconds.
Answer: 90°
Explanation: the sum of all the angles in a triangle = 180. So 70 + 30 = 90 and 180-90=90
3/4 × 20 = 5/6y
60/4 = 5/6y
360 = 30y
y = 12

I dont understand that sorry
Answer:
The correct option is (C) 10.
Step-by-step explanation:
The five-number summary for the number of teams in each of Brad's fantasy football leagues is as follows:
Minimum: 4
<em>Q</em>₁: 7
Median: 10
<em>Q</em>₃: 14
Maximum: 18
The minimum value is the smallest value in the data set.
The first quartile (<em>Q</em>₁) is the value that is less than 75% of the observations.
The median is the middle most value of the data set. It is the value that is less than 50% of the observations.
The third quartile (<em>Q</em>₃) is the value that is less than 25% of the observations.
And the maximum value is the largest value in the data set.
So, the five-number summary suggests that about 50% of Brad's fantasy football leagues have fewer than 10 teams.
Thus, the correct option is (C).
