You have to do a histogram here:
<span>11 sec: 2 people: probability is 2/50 = 1/25 = 0.04
12 sec: 5 people: probability is 5/50 = 1/10 = 0.1
13 sec: 8 people: probability is 8/50 = 4/25 = 0.16
</span>14 sec: 10 people: probability is 10/50 = 1/5 = 0.2
15 sec: 21 people: probability is 21/50 = 2.38
16 sec: 2 people: probability is 2/50 = 1/25 = 0.04
17 sec: 2 people: probability is 2/50 = 1/25 = 0.04
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
= 
Multiply both sides by 7, thus
AC = 7sin40° → A
Your answer would be 9 1/8
They can NOT. A right angle is 90°. An obtuse angle is greater than 90°. All the angles in a triangle must add up to exactly 180°. If two angles are greater than 90° then they will add up to greater than 180, beacuse 90 plus 90 equals 180. You cannot have a triangle with two obtuse angles because they will add up to greater than 180°.
Answer:
median: 28
mean: 55 + 25 + 28 + 42 + 25 = 175 175 / 5= 35
Step-by-step explanation:
median is the number that is in the middle of all of the other numbers
mean is when you add all of the numbers together and then divide the total depending how many numbers you added together.
