Answer:
A
Step-by-step explanation:
You are given the table
This table represents a linear relationship between time and water leaked, because
The linear function has the equation
Find m and b:
So,
Find the x-intercept:
Hence, point (7,0) is x-intercept with the meaning x=7 is the time it takes to empty the water in the pool
Answer:
im soooo sorry but i have no idea.
Step-by-step explanation:
Answer:
34.13%
Step-by-step explanation:
Given the mean score is 450 and the standard deviation is 120.
-The probability of scoring between 450 and 570 can be calculated as below:
Hence, 34.13% of the scores lies between 450 and 570
Let and . By the product rule,
By the power rule, we have and , but are functions of , so we also need to apply the chain rule:
and we have
So we end up with
Replace to get everything in terms of :
We can simplify this by factoring:
Answer:
16 cm, 63 cm, 65 cm
Step-by-step explanation:
Because those side lengths are to big to make a right triangle
