Answer:
(C) 3 feet
Step-by-step explanation:
We have a function of f(x) here. When Sarina throws the ball, it has been 0 seconds since she threw it.
Since x represents the amount of seconds, we can find the height of the ball (f(x)) by substituting x in as 0.
0 squared is 0, 0 minus zero is 0, and 0+3 = 3, so
Meaning that when Sarina threw the ball, it's height was 3 feet.
Hope this helped!
D. Since 8+1+3=12 and the lines between +1 and p= is absolute value so its makes it positive so instead of 1+-8 its 1+8 which is 9 so just then do 9+3.
Answer: 0.6
-------------------------------------------------------------------------------
To get this answer, subtract the given value (0.4) from 1 to get
1-0.4 = 0.6
The reason why this works is because the event either happens or it doesn't happen. There are no other options. So if
A = event happens
B = event doesn't happen
then P(A)+P(B) = 1 which leads to P(B) = 1-P(A)
