Correct me if I’m wrong. But the answer should be 18.75 minutes
We can use the points given to solve for the slope.
Slope formula: y2-y1/x2-x1
7-3/4-1
4/3
Find the y-intercept.
y = mx + b
3 = 4/3(1) + b
3 = 4/3 + b
5/3 = b
The slope of a perpendicular line is the opposite and reciprocal.
4/3 -> -3/4
Write the new equation.
y = -3/4x + 5/3
Best of Luck!
Answer:
To increase an amount by 7%, you would want to use 1.07 as the multiplier. To decrease it, you would use 0.93
Step-by-step explanation:
Answer:
$2.03
Step-by-step explanation:
2.25-(2.25*.1)=2.025
Answer:
Step-by-step explanation:
a. #We notice this is a Poisson probability function expressed as:
x-number of occurrences in a given interval.
-mean occurrences of the event
-The mean is calculated as:
#the probability of no accidents in a 15-minute period is :
Hence, the probability of no accident in a 15-min period is
b. The the probability of at least one accident in a 15-minute period. is calculated as:
Hence, the probability of at least one accident in a 15-minute period is
c. The probability of four or more accidents in a 15-minute period is calculated as:
Hence,the probability of four or more accidents in a 15-minute period. is 0.9997
