Answer:
Bob
Step-by-step explanation:
The "steepness," or slope, of the mountain is the ratio of height to horizontal distance to the base:
Joe's mountain slope = 1200/1500 = 0.8
Bob's mountain slope = 900/1000 = 0.9
Bob's mountain has a greater slope than Joe's. Bob climbed the steeper mountain.
It would be an acute triangle because the lengths are below 90 degrees
Answer:
Step-by-step explanation:
Sum the frequency column to find the total number of students
total = 2 + 9 + 5 + 5 + 3 = 24
number of students finished in less than 20 mins = 2 + 9 + 5 = 16
fraction of students = 
=
Answer:
$40
Step-by-step explanation:
Let the amount of money she has at first be $x.
She put 1/4 for savings, this means she decides to spend 3/4. The 3/4 is equivalent to (3/4)x
Now, she puts half of the money not saved to pay back her sister and has $15 left.
This means the (3/4)x is equivalent to $30. This is because she used half which is $15 to pay back her sister.
Now, since (3/4)x equals 30, we calculate x
(0.75)x = 30
x = 30/0.75 = $40
She originally had $40
The probability of making his 4th attempt is 0.77, since the probability of each attempt is independent.
The probability of making a field goal over 40 yards is 77%
Since the probability of making a field goal is independent, then the probability of succeeding in his 4th attempt does not depend on his previous attempts.
Hence, the probability of making his fourth attempt is the probability of making a field goal over 40 yards in each attempt which is 77% = 0.77
Hence, the probability of making it is 0.77
